Momentum SX5i


The Momentum SX5i is a full range 2.5-way iso-baric floorstanding design which uses four drive units in each enclosure.

Iso-baric loading is a familiar feature on Neat loudspeakers,
this being our favoured system for delivering exemplary bass

The iso-baric 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 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.


Momentum SX5i Tri-laminate Feet Kit

The Momentum SX5i can be upgraded easily with the addition of the dedicated Tri-laminate Feet Kit (as pictured). These feet allow greater stability and overall cleaner presentation. 

(* This kit can also be retro-fitted to the

earlier Momentum 4i model.)
