they used to pay him half a Denari

Seeing as I started off this thread, it's about time I posted a reply!

That's a nice set of custom builds you've got there Tony and they're some pretty serious mids you've got there!  Volt VM752's by any chance?

I see you've also been using 'ring radiator' tweeters, how do you like their sound in comparison to conventional soft dome tweeters?  I was very impressed with their performance especially considering the low price they cost!

Look foward to seeing yours as always!

I'd set up the floorstanders in a much more typical symmetrical fashion, however my mate decided that he wanted more stereo width and he found that the new arrangement caused less issues with reflections in the room.  Unfortunately it's a awkward room for speaker placement when considering the room characteristics and other furniture placement!  He's very happy now with the setup so I'm not going to try and interfere with his stereo setup now.,

You've got it spot on!  It's a kitchen worktop, solid oak and 40mm in thickness.  I rubbed in some natural danish oil to give the finish a nice contrast with the patterns.

It was surplus to requirements from a friend so I recycled it, but it still cost me £200 for half a worktop sheet!

As for the other projects posted:-

perttu - very nice finish, superb quality - looks like the cabs have been veneered, how many ply is the exterior finish on those?  The reason you've had comments about kits is that they look too good to be homemade!  So that's a compliment for sure....  I still want to try veneering speakers but I didn't want to risk it on a build for a friend as I didn't expect that I'd manage to pull it off very well on a first attempt!

Tony Wilkes - your cabinets look understated (not saying they look bad btw!) however I can imagine they sound very clear and accurate.  I used to have some 'Living Voice' floorstanders which used the D2905/950000 tweeters and they had a very natural and non-fatiguing sound.  So would like to hear what yours sound like!

So Chris, your floorstanders look interesting...I was considering trying out some ribbons that looked just like those - I've always been very curious about ribbons but I know that they can sometimes be very difficult to integrate well.  How do you find yours generally sound?

And finally Ibex, wtf that is weird!!  Good to have some music whilst reading the newspaper during an extended crapping session :)

Hi Rossco:

Regarding the ribbons, they are actually made by TangBand and distributed by Monacor.  They are very well made though and that is reflected in the price still being fairly high.  The soft dome midrange is from the same place and also very impressive.  The sound from both drivers is very natural and incredibly detailed.  The ribbons are particularly good on cymbals etc.

The integration between the two with a 5kHz passive crossover is pretty seamless.  I have more of an issue with the integration between the 10" and the midrange, probably because of the spacing, something which will be sorted in the final version.  One issue with the ribbon/soft dome combo is that one is set back into the baffle and one sits proud.  I can't hear any time/phase alignment issues but I will be setting the soft dome back into the baffle further to minimise the path length difference.

I'm wondering whether it would be worth the effort to build a transmission line for the Volt 10" drivers.  They work fine in the reflex box although a little EQ is required to bring the bottom octave up for a flat response.

I should really get round to doing an RTA measurement of them, I've just done it all by ear so far.

Also on the to-do list are the amplifiers, unfortunately my amp designs have stalled for various reasons, mainly lack of time.

Ahh you've made my mind up now Tony, I was wondering whether to go for the upgrade... (ive got the non-super ATC's and you can't get the Supers at the moment).

Where do you cross the domes over at? (On the bottom end....) I see PMC use a 380Hz Xover ... but theirs may be modified?

I see. Volt seem to think the VM752 doesn't drop that low ? (They suggest 500Hz as I recall?).
