The Momentum SX3i is a compact 2-way iso-baric loaded bookshelf/standmount design.

Don’t be fooled by this unassuming modesty – this is a real heavyweight contender with giant-killing credentials. Here, the benefits of iso-baric 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.

Neat Acoustics Momentum SX3i

The new SXT tweeter in the Neat Acoustics Momentum SX3i is one of the finest available at any price. This unit features an inverted anodised aluminium 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 attractive, room-friendly cabinets in a variety of finishes to match any décor.

More importantly, the Momentum SX3i is capable of delivering a compelling musical experience where it really
matters – in the listening room.


Available in Natural Oak, American Walnut, Black Oak and Satin White.

The Momentum Range

The Momentum range models incorporate aspects of the class-leading Ultimatum range, stripped down to be more affordable. The most obvious feature being the use of iso-baric bass loading. This system is an arrangement where two bass units (or bass/midrange units) are coupled together, receiving the same signal, with one unit on the baffle of the speaker, and another concealed internally with a small sealed chamber between them. The benefit of this arrangement is two fold; the bass extension for a given enclosure is equivalent to an enclosure of twice the size, thus allowing very deep bass from relatively small cabinets. This bass output is also extremely well controlled, due to two units having double the motor power controlling the effective area of a single drive unit. The drive units employed are the latest versions of the Neat designed units, as used in the prestige Ultimatum models.

The Momentum range in its current SX guise also uses the exceptional ‘SXT’ type tweeter, designed by Neat Acoustics and using a black anodised dome, with a massive ferrite dual magnet assembly. This is a very dynamic and insightful tweeter, yet possessing a smooth character free of the fatiguing effects attributed to many analytical tweeters.

All Momentum models use low-loss, close tolerance crossover components, carefully designed to extract the maximum performance from the drive units.
