Hello Raceone,
I am glad you're embracing Tannoys. If you go to the Tannoy Yahoo forum site, in the photo section, look up "Custom Heavweights for HPD 315's", you'll find photos of my 150 liter cabinets under construction, and also plans for them. It's something to at least get some ideas from. When I was building mine, there was a paucity of info to be had regarding cabinet design for 12" MG's or HPD's. I had mine built by Frank Wyatt in PA to my specs, they aren't the nicest-looking cabinets, but boy, do they work.
I then built custom outboard crossovers with premium parts, and changed from the rot-prone foam surrounds to hard edge, which improved their performance, and will never rot.
Monitor Golds don't have this problem, but are not built to be able to handle as much power as the HPD's. I run mine with either 500 Wpc class D, or 9 Wpc SET 300B, I happy listening to either.
I would stick with 12 DC's, the 10" (Turnberry) Tannoys I've heard didn't quite do it for me.
Let me know if I can help, audiophildan at yahoo dot com is my private email (or was, until now) if you want to discuss one-on-one any of this.
Regards,
Dan
