Its usually quite difficult to get diy stuff to look good in pics..........these look great......I'v spent many hours in a workshop making things...(wish i still had access to a cnc miller or laser cutter :().......i would be surprised if these were not better than the originals, although its a while since I have seen any close up.

Great job..........

now they look great , how are they sounding

Thanks for all the positive feedback on these speakers, the finishing has taken me every evening this week for about 4 or 5 hrs an evening, waiting for drivers now.
I made a "stretcher" for the grille cloth, i am not a fan of the original Tannoy cloth so have gone with a very fine painters linen over an oak frame-feedback on this would be good.
Dave-yes lots of work here and thanks for your input and for letting me crash your excellent thread.

Thanks for looking Si.

I think all the superlatives have been said before:)

Yes, really superb. I bet you can't wait to get the driver in there and fire it up.

Hi Simon
I'm pleased some one has picked up the baton and run with it. Are you using External Xovers. This is where the fun starts and the tweaking happens.

I am using external cross overs but will send them with the drive units up to Lockwood for their thoughts, a little tweaking i expect once the drivers are mounted but not too much i hope.
Really want to hear them now so a rather frustrating wait, hope its not too long now, i have bought an Acoustic Masterpiece AM201 (Airtight) to use with them so thats also something i am looking forward too.:)

Best Si.

Yes I know how agonising the wait can be. Thats a sweet amp. Its a pity you are so far away Simon.
I would love to hear that setup.

Hi Folks,

Minor set back here, the drive units were not re conable to 3839:(

...so to cut a long story short I will be using HPD 385's which will arrive on Monday.

This set back has meant re designing the inside of the baffle to fit the 385's and also changing the external cross overs to suit these drivers.

I have bought the 385's with the original cross overs which i intend on comparing with the external ones but they will have to be tweaked owing to the added efficiency of the bass driver-can anyone offer any advice on this as this is where i have no experience at all.

Dave-it is a nice amp, not heard it yet but its beautifully built as you would expect from an off shoot of Airtight, the previous owner used it with GRF's so it should be a good match at 22wpc.

Many Thanks in advance,

Si.

Regarding cross overs- i have gleaned a little from the Yahoo group and a few other sources so am on the right track i think-i have a schematic for a MG 15"for the Autograph which may be ok for the Westminster, component changes are changing the cap on the input to hf section to 10uf, changing the 50 ohm resistor to 100 ohms and the 20 ohm resistor to 10 ohms, another important change seems to be moving the drivers tap of the autoformer to the lowest rather than the second lowest tap which steps the tweeter level up more to match the efficiency of the woofer with horn loading to its full range-i will work through it with Nick and see how we get on-the drivers turned up yesterday so measured out and cut new carriers for them so the cross over is the last piece if the jigsaw.

Any other ideas for tweaking the 385 cross over for use in the Westminster.

Dave-what did you do for cross over duties?

Ta Si.
