Cheers Joe,
I ended up with no internal damping on the first pair after much experimentation and waiting for the drivers to settle in. They sound really nice the way i have them, the originals had no damping so i thought this may be the outcome. I suspect the same will be the case for these. Ferenc, the fellow who's build gave Dave the inspiration to build these used a lot of internal wadding but i found i preferred the sound on my build without...i have about £150 worth of various damping materials that are now redundant but will try them again on the new pair and do some measuring again.
I hope that the more solid curved sections and the ply will be a nicer sound through these but will have to wait and see...must chat re. cross overs at some point again, will be in touch in a few months
One reason for the curves being built outside and not into the cabinet is that veneer can be vacuum pressed onto them so a nice veneer needs to be chosen for my third and final pair.
Cheers Si.
Yes I can see where you are heading with this, I also removed all the dampening from all the horn paths. With the result that the music opened up considerably. Over some months also experimented with various equipment.
With no obvious path to follow(we don't have concise and proven plans for covers, drivers or cabinets)it is very much feel your way along. For this reason I think it is a great idea to share our knowledge as to individual results with this experiment.
I filled the space above the driver with sand bags and the enclosure on either side as well. Attach carpet squares to the rear baffle directly behind the driver enclosure and the enclosure below. The cabinet has much less resonance now particularly with the addition of stiffening the outer panels.
The xovers have without a doubt had a very significant change to the sound. I can't stress enough how important this is.
Of course the addition of an Audio Research PH5 Phono Pre made a huge difference to the result as well.IMG_1458.jpg
