Tannoy Dual Concentric HPD 385's In DIY Rectangular GRF Cabinets

I was lucky to find a pair of Tannoy HPD 385's on eBay at a knock- down price some years ago, they were damaged, so that was a benefit to me as I knew that Lockwood Audio in London UK were capable of reckoning them for a reasonable cost. I researched which cabinets to build and settled on the Rectangular GRF design. Some say that this is not the best cabinet and I possibly agree, several people on the web have built the GRF's and then converted them to a ported design. I have stuck with the GRF horns and with a lot of fiddling, I am now happy with the result, although they are possibly a bit bass light. If you are looking to build these, I hope that the video will help you. Please click "Like", thanks
