    I'm not sure what you mean. The Tannoy is a full range driver, although you could use a subwoofer with it.

    Picking a suitable box design should not be too tricky. Bass can be extended below the driver resonance with a bit of port tuning. Port dimensions can be worked out once you pick a cabinet volume.

    I can't see why you would not be able to use the existing crossover. You might want to use an alternative terminal plate equipped with banana sockets. That should be easy to sort.

    Your suggestion of "the bigger the better" for a Tannoy Is even more useless, unfortunately, that's another Internet myth.

    The only way to do It properly, Is to completely reverse engineer the speaker - crossover and all. Everything else Is just guesswork. If Steve gave me the Internal volume and port dimensions, I could model the driver using the specs In franks link. If It matched the actual port tuning (beans trick) then that's part of the puzzle solved.

    Hi again, and thanks so much for your continued input! What I meant when talking about an additional driver was that it the driver required it. I would much prefer to use the vx12 as is, without additional complexity / cost. I see mention of cabinet size in litres but I find it hard to visualise. I am not that restricted on size but I would much prefer a cabinet with as slim a front profile as possible. Yeah I was looking at the connectors on the back and as you say they are far more than would be required and in fact I already have a pair of recessed banana plug connectors that would do the job. I have access to a commercial woodworking shop and all the machinery I could dream of too.

    Thanks Steve

    You know I was generalising.

    You'd suggest smaller boxes would you?

    Tannoy quote 36.07 litres. I have just measured the 4 ports and each is 3" (76.2mm) long and 2" (50.8mm) wide.

    I can only go by what you said "the bigger the better" - which is rubbish.

    I didn't suggest smaller boxes either - more rubbish.

    Marco, If you read through, you'll see I was only replying in the same manner I was spoken too, and correcting misinformation at the same time.

    I'm a little busy just now. Who was speaking to you in that manner? In any case, as they say, two wrongs don't make a right...
