Here's the model with it based on driver 1 and then on driver 2-I'm hoping driver 1 measured correctly and driver 2 was messed up by me!

Right, remeasured the drivers, but didn't have the time to do added mass/known volume so have just got a fresh comparison between the drivers and also measured them mounted isobarically face to face. Looks like I didn't botch the measurement as both came out pretty much the same as before Will get them both hooked up for some burn in and see if it brings them more in line with each other-otherwise I'm just going to have to accept they'll be a little offf from each other or use some different subs: got a pair of REL 8", pair of IDQ10's and a Pioneer flat sub that would all give the right load for the amp I'll be using.

The clearout ones that were on ebay about five years ago? If so, so have I. Strangely, currently in an isobarik BR of about 30 litres.

Not using them at the moment though, as the old Maplin mosfet amp I powered them with self destructed...

They may have come from there a friend had 8 of them in his ML, now he has 8 Focal 5" subs and I had the two REL and the IDQs off him-Yuri on talkaudio and Diyma, not sure if he frequents here. Not done enaything with them except pull the specs with WT3! Was planning an underbed enlosure for them-they may now make it to the living room...

I've decided to go ahead with this and just see what the output is like, got a friend with CNC facilities so will get him to do the cutting and then get the glue and screws out

Thanks for everyones assistance, will post some pics of the build process as and when it starts!
