The High End acoustics of the Response series will work perfectly with almost any amplifier (including tube push-pull models) with a nominal output impedance of 8 Ohms. And despite the unprecedented sensitivity (88 dB per 1 W per 1 m), even a 20-watt amplifier can drive the D18. The cabinet is made of MDF boards with excellent quality finishing with precious wood veneer - cherry. In addition, it is necessary to note the excellent damping of the internal volume of the speaker with high-quality materials. The bass reflex of the speaker system is directed towards the floor, so the speakers can be installed in close proximity to the wall.Height 930 mm, width 190 mm, depth 265 mm, weight 25 kgResistance 8 Ohm, sensitivity 88 dB/W/mThe original studs were replaced with Soundcare SuperSpeake. There are original boxes.

A pair of highly regarded Proac Response D18 Floor standing speakers with Maple finish. Very good condition and in perfect working order. The speakers are bottom ported to simplify positioning; there are currently foam pads attached to the bases, but I also have the original spikes. There are many reviews online including the following ProAc Response D18 review | What Hi-Fi? (whathifi.com) I have found the speakers to be very good allrounders, that work very well with Jazz, Rock and Orchestral. There are no chips in the veneer. There is a slight colour variance where the covers have been in place, the photo of the speaker to the left best demonstrates this. The original covers are also in very good condition. I have the original boxes and packaging so could courier to the UK only. This will be relatively expensive as a result of large size and weight and will be in addition to the buy-now price. Otherwise pickup from Chelmsford, Essex. Please ask any questions.
