Mid Detail

ProAc have improved the mid-range detail and a opened up a cleaner, faster and more extended bass response. A new studio monitor quality bass driver was designed for the D48, featuring a special impregnated cone and mid frequencies tuned by a cap of greater size than standard. This gives the new unit greater mid-range detail along with excellent bass control giving a tighter and more extended response.

Dual Bass

The two new bass drivers are each loaded through ProAc's special floor loading with side vents, this makes the loudspeaker easier to place and reacts less to surroundings. The two bass units are then seamlessly mated to our ribbon or dome tweeter depending on your preference.

With such a large slim floor standing design the sound stage is superb being very large and with pinpoint imagery. Another achievement for the D48 is its ability to create large orchestral works as well as heavy rock music.

HQ Filter

The D48 has a high quality filter network designed by Stewart Tyler comprising of the finest components, ProAc cable on a special board. The filter is also split for bi-amping and bi-wiring. This is one of the best designs from ProAc and should please all audio files regardless of their taste in music.

D40 Legacy

The ProAc Response D48 is built to replace the immense flagship Response D40, and has some big shoes to fill! ProAc aren't in the business of making tweaks and changes for the sake of it, so for all purposes the D48 is a wholly new speaker.

ProAc have moved away from the carbon fibre cone material utilised on the D40, instead opting for a carbon fibre pulp which delivers improved midrange frequency reproduction as well as tighter bass with less low frequency hangover.

Enhanced Sound

These differences give the listener a more detailed, open midrange and a more expansive soundstage. Also, the leading edge of bass instruments is more audible with less muddling in comparison to other carbon fibre based drivers. The cabinet used for the D48 is the same size as the outgoing D40.
