Putting together a box o' drivers...
Will be a while, as it is slow going in my garage, but I have a box of drivers I am putting together. I am in the process of reducing my inventory, so as per my usual method I will not be asking much for these.
So far (if I recall correctly), these are in the box:
Qty: 4 Gradient Axis 7" woofers. Visually similar to the Dayton RS paper woofers, but with a different motor. The Fs is slightly higher, Xmax slightly lower, but impedance at Fs is considerably higher than Dayton. I think they end up being a few db more sensitive than the Dayton.
Qty: 2 Gradient Axis high sensitivity 5" or 6" midrange. These are very nice. I think someone here did a build with these last year.
Qty: 5 MCM Audio Select 1" soft dome tweeters. These are great tweeters, with world class distortion above 2K. Very nicely designed rear chamber, copper cap.
Qty: 2 Dayton Audio 4" square frame things, use the plastic frame, aluminum cones, you know the ones. Probably make for a very solid dedicated midrange if you are willing to deal with the square frame. They measure 104mm x 104mm which is also the dimensions of the Beston ribbon tweeter. Can't remember if these are 4 or 8 ohm.
Qty: 2 Small form factor ring radiators. Not sure they are made by Tymphany, likely a Chinese clone, but they have some pretty copper nipples. At some point I measured them, good consistency and Fs somewhere in the 900 range IIRC. Flat above 2K.
Qty: 2 MCM Audio Select 55-3669. These are the black anodized, copper-capped version of the Barbie Girl woofers. These are incredibly good for the money, and hold their own against any number of woofers under $50-$60. A pair in a tower around 1 cubic foot will play loud to 40Hz, with decent cone control below Fb. JP has done some advanced modeling along those lines, make him design the bass alignment for you.
There is still room in the box for some stuff, as I sort things out I will top it off and send it out for the cost of shipping. All or nothing. Some very nice potential builds in this box, guys. I will also cart it to Iowa this October if any attendees are interested in a pile of very nice, essentially free (you may need to ply me with a few alcoholic drinks while there) drivers, although I'd just as soon get that space in the garage sooner than later.
I a working off memory here, so there may be other drivers or missing drivers than what this list calls out. I will try and finish the sorting process this weekend and update here.
Stay tuned!

Qty: 2 Peerless by Tymphany DA25 something or other, 6 ohm dome tweeters.
Box is pretty well full, the person who made dibs will probably be at IowaDIY so I will deliver it there.
Thank you
