Best cab for Tannoy 12"

About twelve years ago, I decided a return to Tannoy was something I had to do. I bought a pair of HPD 315 (12" Dual Concentric from the mid-seventies) on Ebay UK. I had a pair of enclosures made that are 150 liters, bass-reflex that are 17" X  20" X 48" H. They are made of a 3/4" inner MDF layer laminated to 1 1/8" MDF for 1 7/8" net. They weigh 192 lbs. net, w/o drivers or crossovers.

They perform extremely well, though mine are 58" from the wall behind them. I expect they would work pretty well close to the wall, since the reflex ports are in the front of the speakers. The original crossovers are mounted in a small pocket at the bottom rear of the cabinets, and can still be used by changing some connections in that pocket. 

I use some DIY built outboard crossovers using Alpha Core ribbon inductors, Mundorf S-I-O caps, and Dueland resistors.

I love these speakers unreservedly, they will be my only speakers until I draw my last breath.

You can read about them in Virtual Systems, "Done For Now", titled "The Summit".  By the way, my oldest son's name is Brook. I don't know where you are located, but Google is your friend. Check with reputable cabinet makers in your area.

Best of luck on your project, regards,
Dan

broockies, the way to go would be a tal,l narrow transmission line enclosure. I saw a design in a you tube video that was very clever. Google You tube transmission line speaker and you should come up with it. It would be like using two 12 inch drivers instead of one. Way better bass.

Hey Mijostyn;
I had a pair of IMF (Irving Freed) Studio Monitors. the IMFs were serious
transmission line floor-standers from the late '60s - info down to 16 CPS
(oops - Hz) on the bottom. 12 " driver, and cab was 16' wide, as I recall.
Made me a fan. I'll check your suggestion out.
Dan; I'm interested in your crossover note: Investigation indicates 
improving technology offers significant improvement over stock
Tannoy x-overs. Could you send pics or a schematic  of your x-over mod to me?
Here's more info on my situation:
Room: 27'x 17', 8'H.;  Fairly "live";  Kit: Oppo 95, resto Mac C-37,
resto MC-7270 (so I'm a Gordon Gow fan). Prefer a warmer, expansive
sound to a brighter, analytical one. Inclusive, rich orchestral over
hyper-definitive, close-miked. 
Another question (too many?): Could you guys identify a couple of
top-level Tannoy resto sources? Several in England, but who needs the
shipping costs? This would be most helpful !
Your thoughts?

I forgot to ask, Islandmandan, is there any way you could send 
specs and pics on your Cabs? These sound interesting, as they are front- loaded (bass reflex) and the wall problem is minimized.
he dimensions are nearly perfect !

Brookies, did you check out my system page on Virtual Systems? There's quite a bit of information and photos there, including those of the outboard crossovers.

I don't really have specs, as the enclosures were built for me using the limited information I was able to find regarding cabinet designs twelve years ago. Google Hans Hilberink's Tannoy forum, lot to read about and learn there. Check out Speakerex in Florida, they have parts and do a lot of service work on Tannoy. There's a Tannoy Lovers forum on Facebook. If you still need more info, try PM'ing me, I will do what I can to help.
