ProAc Response D48D and D48R Loudspeakers.
ProAc Response D48 / D48R Loudspeakers - The Response D40 has successfully been in production for nearly 4 years, but with new driver technology now available to ProAc the decision was made to upgrade this model to the D48 available in both ribbon (R) and soft dome (D) mode.
The D48 comes with an all new bass / mid driver with a special modified cone made from carbon fibre and pulp. This driver has all the attributes of being stiff, light and impregnated with pulp to damp out any resonances associated with thin stiff material. The new cone brings unrivalled midrange, being richer and more natural, negating the use of a midrange unit.
The new cone also has a very tight extended bass response.
The new carbon fibre pulp cone is made from impregnated carbon fibre pulp, the cone is terminated with a unique new roll surround giving the cone a very linear extended throw, important for bass extension.
The new D48 utilises 2 new 6.5 carbon fibre pulp full range units achieving a powerful and extended bass, plus a new rich and detailed mid-range. These bass drivers are loaded through an equalised vent to air under the speaker and then side vented using 2 side bars to couple to the room.
Areas of improvement have been mid-range detail and a cleaner, faster and more extended bass response. A new studio monitor quality bass driver was designed for the D48. It features a special impregnated cone and mid frequencies are 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. The two new bass drivers are each loaded through our special floor loading with side vents, this makes the loudspeaker easier to sight 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.
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.
