Neat Acoustics Momentum SX5i

The iso-baric principle is exploited in quite a radical way in the design of the Neat Acoustics 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 anodised aluminium 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 cabinets 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.


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

Momentum SX5i Neat Feet Kit

The Momentum SX5i can be upgraded easily with the addition of the dedicated Neat Feet Kit. These feet allow greater stability and overall cleaner presentation.

(* This kit can also be retro-fitted to the earlier Momentum 4i model.)

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.
