Very recently I bought a pair of Tannoy HPD 315 A with crossover for Tannoy Cheviot. I want to make a cabinet like Tannoy Cheviot Legacy. I could find and get cabinet plan for vintage Cheviot, but I need the cabinet measurement of Legacy. Can someone please help me getting it. Regards

It's design is not public, it's still a cabinet that is in their catalogue. But it's a basic ported cabinet with a dual round port. So measure the driver (or find specs of it) and it's rather easy to design in a similar styling. The drawing i included is a schematic design from how it looks inside.

Thank you so much for your reply. I have also seen this one, and probably the dimension of old and new cabinet is almost same as I see in various pictures. I have confusion on the following issues:
1. Cheviot vintage has got one port, whereas Legacy has two ports and located at the middle of the cabinet. So, what would be the port length if I put two ports in the cabinet.
2. If I change the cabinet then do I have to change anything in the crossover or I can use the same crossover. I am in the process of replacing the old caps.
3. Any suggestion about stuffing damping material.
4. How the new tweeter tone control of legacy functions, I mean the mechanism inside, I also want to change the and tone control switch and DIY the new tone control system.

I don't know, that is all classified info as it's an actual model, the only info i have is the drawing. So measure your driver and try to reverse engineer it.
Good to know, but DIYers being DIYers, maybe some reverse engineering/best guess here:

1, 3: Will have to use Hornresp
to 'guesstimate' based on Cheviot info.
2. No, the XO point is way above the cab's bandwidth [BW].
4. No clue, but the links I just posted is best 'bet' along with 1,3 AFAIK.

Thanks for the guidance. Let me understand what all these says and how to implement. I'll update this post if I can make some way out.
