A single PMC DB1a active speaker.  Built in amp rated at 120W.  XLR balanced input and built in volume control.  Bass extension way beyond what you would think possible from a speaker this size due to the transmission line.

Complete in box with all the paperwork etc.  I bought a 5.1 set of these speakers a few years ago planning to do a balanced, active home cinema install.  This is the final speaker in the set.  It has been out of the box and tested (fully working) otherwise as new.  There is one very slight mark on the bottom surface as pictured.  

I have wall brackets for the speakers which bolt to the 4 holes you see on the back of the speakers - available for purchase by the winning bidder.  

The last pair of these to auction sold for £920 so this is far less than half price.  

Shipping cost includes full cover for loss or damage, I can ship for £15 without cover or you can collect from Guildford.
