Iota Series

Iota Overview

Neat Acoustics’ Iota Series takes its given name seriously (especially if one considers their physical size):

 

i·o·ta
īˈōdə/
noun
1.
the ninth letter of the Greek alphabet ( Ι, ι ), transliterated as ‘i.’
2.
an extremely small amount.
“nothing she said seemed to make an iota of difference”
synonyms: bit, speck, mite, scrap, shred, ounce, scintilla, atom, jot, grain, whit, trace; More

However, only by their size should they to be considered “small” for both the original Iota and its younger, bigger brother the Iota ALPHA are able to present a big, rich sound that belies their spatial footprint (this trait is in fact a Neat family-wide one). And recently with the birth of the youngest, biggest brother the Iota XPLORER, the Neat Acoustics Iota Family is complete. This allows music lovers to place a high performance loudspeaker in spaces previously not considered ideal for audiophile performance. Added to this ease of placement is the reaction many people have when they first behold them: “Cute! How can something so small sound so big?!”

The answer is that technically speaking, the Iota loudspeaker series share a lot with their bigger Neat Acoustics brethren the Motive SX Series. And now with the addition of the Iota XPLORER, many of the attributes (mid-range and bass drivers; isobaric bass loading) of the Momentum Series have found their way into the largest speaker in the Iota Series. The Iota cabinets are constructed of the highest grade materials and finished with the highest grade veneers in order to show little in the way of seams or fasteners. For the Iota and Iota ALPHA, the main Iota drive unit (which is also the bass unit as well in the Iota ALPHA) is a smaller version of that used in the Motive speakers. It’s a 4 inch polypropylene cone with a ferrite magnet assembly. However, they break from their brethren when it comes to the tweeter. In Iota and Iota ALPHA, the tweeter is a 2 inch vertical planar magnetic ‘ribbon’ device, while the Iota XPLORER features for the first time anywhere in a Neat Acoustics loudspeaker an AMT (“Air Motion  Transformer”) tweeter. For the Iota loudspeaker series, the choice of tweeter is critical, because the tweeter lends the whole speaker its essential character and integrity. As with all Neat Acoustics speakers, here the tweeter’s strengths of superb dynamic contrast and accurate tonal color are well matched to those of the main drive unit.

Do you need an iota of something in your life? Well, read on and then go listen to the Iota Series. If you have further questions call or visit your local Neat Acoustics specialist or call us at HFS. We’ll still recommend you go check them out in person at your local specialist’s store, though regardless we’re happy to answer any questions you may have!

Iota

The Neat Acoustics Iota incorporates the implementation of radical and unorthodox thinking in order to offer the same integrity and musical capability that distinguishes all Neat loudspeakers. It is especially suited to the current crop of all-in-one streaming systems, from which a very high level of sound quality can be attained, but space is usually at a premium.

The main drive unit is a smaller version of that used in the highly successful Motive range; a 4 inch polypropylene cone with a ferrite magnet assembly. The tweeter is a 2 inch vertical planar magnetic ‘ribbon’ device. The choice of tweeter is critical, because the tweeter lends the whole speaker its essential character and integrity. In this context, the tweeter’s strengths of superb dynamic contrast and accurate tonal color are well matched to those of the main drive unit.

This tiny loudspeaker is extremely flexible in terms of placement. It can be placed on shelves, sideboards, worktops or desktops (some form of isolation is recommended ). There are also dedicated stands available upon request.

The Iota can also be mounted on wall brackets if required. 6mm (M6) 60mm-spaced threaded holes are accessible on the rear panel to fit a range of widely available proprietary wall brackets, such as the B-Tech BT33 model.

Iota ALPHA

Neat Acoustics’ loudspeakers have long been renowned for creating big sounds from compact and elegant enclosures. However, the Iota ALPHA succeeds in stretching this concept well beyond the limits of what might be expected.

The original Iota loudspeaker has been a huge and continuing success since its appearance in 2011, and the idea of a low-down floor standing version has been mooted ever since. All that was necessary for the new model was to retain the exceptional abilities of the Iota and build on these in a floor-standing configuration. This is easier said than done, of course. But the Iota ALPHA delivers completely on target.

The crossover is a simple two-and-a-half-way design, employing 1st & 2nd order slopes. The crossover components are all hard-wired, with point-to-point connections in order to maximize integrity. The crossover components are of premium audiophile quality and include Mundorf Supreme capacitors and low-dcr air-core inductors.

At a mere 19.2” or 45cm tall the Iota ALPH can be placed discreetly in the room, yet it delivers a genuine full-range musical experience on a scale that suggests a far bigger (and more expensive) loudspeaker.

Visually deceptive, the Iota ALPHA required some unorthodox “imagineering.” The basis of the original Iota (the main drive unit and the EMIT type planar magnetic tweeter) is housed in the top section of the cabinet, in a sealed  volume, angled upwards. This section is configured as a two-way closed box loudspeaker. The whole of the ported lower section is dedicated to augmenting the lower frequencies, via a downward-firing 134mm drive unit mounted on the bottom panel.

Iota XPLORER

Neat have taken the concept of the groundbreaking Iota ALPHA to a new level with this intriguing additional model to the Iota range.

Introducing the Iota XPLORER. This exciting new design uses the same basic configuration as the Iota Alpha, in an enlarged form. The top section is sealed off from the lower, and acts as a two-way infinite baffle loudspeaker. It houses Neat’s own P1-R3 170mm bass/midrange drive unit alongside an Air Motion Transformer (AMT) tweeter in a horizontal array, as per the Iota and Iota Alpha models.

The lower, ported, section of the XPLORER houses not one, but two of Neat’s P1-R2 bass drive units. These are similar to the R3 unit, but specially tailored for extended low-frequency response. One unit is located on the bottom panel, facing the floor, whilst the second is located internally, directly above the first, in a sealed isobaric arrangement, handling only low frequencies and acting as an integral subwoofer system. Isobaric loading allows deep, well controlled LF performance from a compact enclosure.
The IotaXPLORER delivers a compelling portrayal of all types of music. Like the Alpha, the XPLORER belies its small stature with a full-range agile presentation and huge soundstage, which projects far beyond the modest confines of the cabinet.

Motive SX Series

Motive SX Series Overview

The Neat Acoustics’ Motive Series was introduced in 2005. In 2013 the entire Motive Series was revised to the current ‘SX’ status with the addition of the new SXT tweeter. This tweeter, which is also used in the Momentum SX Series, employs a massive magnet system with an anodized aluminum driver. The end result is an detailed yet musical tweeter with outstanding clarity, power handling, and smooth high frequency performance. To match this new tweeter the Movtive Series English-made cabinets received further tuning refinements to their structural elements. The electronic internals as well were treated with some key upgrades in the crossover. All of these SX Series upgrades have been mated with the excellent polypropylene mid-range and bass driver to produce a beautiful British loudspeaker with a sound that matches its physical beauty.

Do you need a motive to add more music to your life? Well, read on and then go listen to the Motive SX Series loudspeakers. If you have further questions call or visit your localNeat Acoustics specialist or call us at HFS.

Momentum SX Series

Momentum SX Series Overview

The quest for affordable high performance is addressed in the Neat Acoustics’ Momentum SX Series. Here, Neat seeks to deliver valuable aspects of their Ultimatum technology such as the isobaric woofer configuration and performance at a much lower cost. The Momentum SX range effectively bridges the gap between the Motive SX and Ultimatum ranges, offering a glimpse of the consummate performance of the award-winning Ultimatum models, but with the price vs performance values of the Motive SX models.

The Momentum SX models use the same low frequency drive units and isobaric bass loading principle as is employed in the Ultimatum models. The Momentum models are now in ‘SX’ guise, using the same anodized aluminum dome tweeter as the Motive SX models. To house this remarkable collection of drivers in each speaker the Momentum SX models offer class-leading performance from elegant, high tech enclosures which take up a minimum of floor space. The Neat Acoustics Momentum SX range has been developed in the established Neat fashion: listening trials and empirical experimentation rather than a reliance on technical measurements, allowing the music to dictate the design and character of the system. 

Once the ball gets rolling it’s often difficult to stop it. That’s often called “momentum” and likely once you start listening to your music with a pair of Momentum SX loudspeakers it’ll be difficult to stop listening! Well, read on and then go listen to the Momentum SX Series loudspeakers. If you have further questions call or visit your local Neat Acoustics specialist or call us at HFS. We’ll still recommend you go check them out in person at your local specialist’s store, though regardless we’re happy to answer any questions you may have!

Momentum SX3i

 

The Momentum SX3i is a compact 2-way isobaric loaded bookshelf/stand-mount design. Don’t be fooled by this unassuming modesty – this is a real heavyweight contender with giant-killing credentials. Here, the benefits of isobaric bass loading combine with the significant virtues of a compact enclosure – to magnificent effect.

All of the drive units used in the Momentum models are custom-made to Neat Acoustics’ designs. The new SXT tweeter is one of the finest available at any price. This unit features an inverted anodized aluminum dome and heavy duty ferrite magnet. With a dynamic delivery of great insight, along with complete freedom from compression effects, it is also very easy to listen to for long periods without a trace of ‘listener fatigue’. Coupled with Neat’s long established R2 & R3 6.5″ doped paper cone mass/midrange unit, this is a combination made in heaven.

The close tolerance Mundorf MCap Supreme capacitors and chokes used in the hardwired crossover networks are, likewise, made to our exacting requirements by leading suppliers. All of this technology is presented in an attractive, room-friendly cabinet in a variety of finishes to match any décor.

Perhaps most important to note: the Momentum SX3i is capable of delivering a compelling musical experience where it really matters – in the listening room.

Momentum SX3i Specifications

  • Design: 2-way isobaric bass reflex
  • Bandwidth:  30Hz – 25kHz
  • Impedance: 6 Ohms (minimum 4 Ohms)
  • Sensitivity: 87dB/1 watt
  • Dimensions (H x W x D): 15” x 8.7” x 10.6” or  38 x 22 x 27cm
  • Weight: 19.9 lbs. or 10 Kg each
  • Standard finishes: Natural Oak, American Walnut, Black Oak, Satin White

Momentum SX5i

 

The Momentum SX5i is a full range 2.5-way isobaric floor-standing design which uses four drive units in each enclosure. Isobaric loading is a familiar feature on Neat loudspeakers, this being their favored system for delivering exemplary bass performance. The isobaric principle is exploited in quite a radical way in the design of the Momentum SX5i, which features two 6.5″ bass drive units in an integral subwoofer arrangement (this part of the system is hidden from view).

An ‘Ultimatum’ type bass/midrange main driver then handles frequencies up to the crossover point, where the new ‘SXT’  inverted anodized aluminum dome tweeter, with its fluid & dynamic HF response, takes over. All of the drive units used in the Momentum models are custom-made to Neat Acoustics’ designs. The close tolerance capacitors and chokes used in the hardwired crossover networks are, likewise, made to our exacting requirements by leading UK suppliers. All of this technology is presented in attractive, room-friendly cabinet in a variety of finishes to match any décor.

More importantly, the Momentum loudspeakers are capable of delivering a compelling musical experience where it really matters – in the listening room.

Momentum SX5i Specifications

  • Design: 2.5-way isobaric bass reflex
  • Bandwidth: 25Hz – 25kHz
  • Impedance: 8 Ohms (5 Ohm Minimum)
  • Sensitivity: 88 dB/1 Watt
  • Dimensions (H x W x D):   41.4” x 8.7” x 9.1” or 105 x 22 x 23cm
  • Weight: 55.1 lb. or 20 Kg each
  • Standard finishes: Natural Oak, American Walnut, Black Oak, Satin White

Momentum SX7i

 

The Momentum SX7i delivers a true full-range performance from a  room-friendly enclosure with a relatively small footprint, measuring just 10.6” x 11.4” or 27 x 29cm. This means it effectively takes up little more floor space than the average stand-mount design.

To achieve its extraordinary level of performance, an extensively braced and damped cabinet constructed from 18mm high-grade MDF is used, with each of the five drive units housed in its own discrete cavity.

The upper section of the enclosure is, in effect, an infinite baffle two-way loudspeaker. Neat’s SXT tweeter is an anodized aluminum type, which delivers a detailed presentation, with extremely low compression, yet is also easy on the ear and free of the fatiguing effect of other highly analytical HF units. The SXT tweeter is flanked by two of Neat’s recently upgraded P1/R3 bass/midrange drive units in a d’Appolito arrangement. This section is fed from a simple 1st / 2nd order two-way crossover using superior quality low tolerance components. The crossover point here is 3.8kHz.

The lower half of the enclosure is sealed from the upper half and configured as a compound (isobaric) bass-only section. One of Neat’s P1/R2 drive units is located on the bottom panel, firing  downwards. This is augmented by an identical drive unit located above it, with a sealed chamber between the two. These operate together, in phase. The isobaric system enables the drive unit to deliver extremely deep and controlled bass from a comparatively small enclosure. This section is tuned by reflex port.

Momentum SX7i Specifications

  • Design: 2.5-way isobaric bass reflex, with integral isobaric sub-bass unit
  • Bandwidth: 22Hz – 25kHz
  • Impedance: 8 Ohms (5 Ohm Minimum)
  • Sensitivity: 88 dB/1 Watt
  • Dimensions (H x W x D): 47.3” x 8.7” x 9.1” or 120 x 22 x 23cm
  • Weight: 79.2 lb. or 36 Kg each
  • Standard finishes: Natural Oak, American Walnut, Black Oak, Satin White

Ultimatum Series

Ultimatum Series Overview

The Ultimatum project is a labor of love for Neat Acoustics’ founder Bob Surgeoner. It began in 1995 as a no-compromise design intended to deliver the very best attributes of Neat’s accumulated ideas and expertise, and development took place over several years.

Originally conceived as a single model, the prototype sported several design cues which can be identified in what eventually became the Ultimatum MF9 loudspeaker six years later. The slim, 59” or 150cm tall enclosure, with separate cavities to house each drive unit in an extended d’Appolito array. Employing 4 x 168mm main drive units in each cabinet, the driver configuration was designed to simulate a point source.

The Ultimatum MF9 was launched in 2001 to great critical acclaim and international commercial success. It was soon followed by smaller variants, the 47” or 120cm high MF7, the 39” or 100cm MF5, and the stand-mount/bookshelf MFS model. All of these versions adhered to those principles which rendered the Ultimatum models as being among the very best in the world.

The original line up was upgraded recently to ‘XL’ versions, further improving all aspects of their performance.

Have you set yourself an ultimatum to finally have an ultra-high performance and musically satisfying loudspeaker in your life? Well, read on and then go listen to the Ultimatum Series loudspeakers. If you have further questions call or visit your local Neat Acoustics specialist or call us at HFS.

Ultimatum XL10

 

The Ultimatum Series of high-performance loudspeakers was conceived by Neat Acoustics founder Bob Surgeoner in 1993 and launched in 1999 with the introduction of the Ultimatum MF9.  The XL10 is the result of a complete revision of the MF9, building upon its considerable strengths in order to deliver a world-class full range performance for the 21st century.

The enclosure comprises eight discrete internal cavities, each optimized for purpose and each different. The bass/midrange volumes are larger to suit the tuning whilst the main HF cavity is small to increase rigidity and resist back pressure from the main drive units. The two EMIT super tweeters are similarly isolated.

The main structure is damped 18mm Birch Plywood sourced from slow-growing forests as this ensures the densest, most consistent material. The drive unity-baffle sections are constructed from a 45mm thick ‘sandwich’ of Birch Plywood, Polyethylene and MDF. This provides a rigid non-resonant platform which allows the drive units to operate with minimal coloration.

All of these features are woven together in the traditional Neat Acoustics fashion: hundreds of hours of listening tests, empirical experimentation and years of expertise guarantee that the end result is a classic loudspeaker with qualities that few can equal.

Ultimatum XLC

 

The Ultimatum XLC Center-Channel loudspeaker has been designed to complement all Ultimatum main speakers in the context of multi-channel & home theatre systems.

The XLC incorporates key Ultimatum features; a multi-chamber, multi-driver enclosure constructed from Birch Plywood. It is a 2-way design, using four of Neat’s 168mm main drivers (two of which have been re-designed to meet the exacting requirements of the Ultimatum range) in a reflex tuned isobaric configuration, coupled with SEAS soft dome tweeter with Sonomex surround.

Three years of development have been spent on solving the problem of deleterious vibrational effects and the driver-mounting baffle is decoupled from the main structure via a polyethylene membrane. The total baffle is a 45mm thick ‘sandwich’ of Birch Plywood, Polyethylene and MDF. This provides a rigid non-resonant platform, which is ideal for optimal performance of the drive units.

The crossover is a minimalist 3-element type (plus damping & attenuating resistors) employing precision tolerance, low loss air-cored inductors and Neat’s newly-developed polypropylene capacitors.
