I use a pair of Tannoy 215 DMTIIs. Very recently I decided to bi-amp them with a pair of Amphion 500s.
Also, I obtained a DEQX HDP-4 preamp. After messing around with the crossover for a while I landed on 1.5khz with a relatively steep slope using linear phase filters. I ended up there just by eyeballing the speaker response and choozing a zone where both the drivers and the tweeter were relatively flat. I know that the original crossover had different slopes on the driver and tweeter but that was not available in the HDP-4.

After time aligning the speakers through the DEQX the sound is STUNNING. I would be happy to pit these against anything available today at any price.
Absolutely love these speakers and listening to anything through them is a pleasure.
