Saw these on ebay--

I looked around the web at 12trxb pictures and the ones I saw look different, like a big cast frame with ridges. Was there more than one construction for these? This pair looks to have a stamped steel frame.

Hmm, I'm no EV expert, but it sure looks like a pristine original to me based on the formed roll surround and '50s era tone control.

There were several versions of these made, some for other manufacturers like Knight.
The early ones had a metallic pinkish color frame and basket and had a couple different versions of the tweeter (very early ones were narrower).
Later versions had a white frame and were seriously heavy. Both came in eight and sixteen ohm versions.

Having used EV speakers for some 30 years I would suggest these....

PS or if you can find them MC8A(s) - much like the Fostex FE207E.
Those are the later cast frame ones. The frame is so heavy that they'd probably survive re-entry from space...
The 12TRXB's model like a poor man's PHY-HP KM30. They look like they'd be great in an open baffle with a SET amp. The 12TRXB had a little less bass when modeled in the PHY-HP baffle compared to the KM30 due to it's slightly higher Fs.
If I had the room for big open baffles, I'd definitely give 'em a go.

Great Fun
I have a pair of EV 12" SP12B and T35 tweeters that I bought in 1975. I haven't used them for the past several years because of the size of the cabinets. I got rid of the cabinets after we moved because I had know where to put them. They were huge.
I pulled the drivers out today and mounted them on simple OB. I used what I had on hand so it's nothing special. They sound wonderful javascript:smilie('😀') and are easily a match for my Fostex FE166-ESR BLHs. This is the first time I have listened to an OB. They are truly special.
The SP12B is running full range. The T35 is crossed using a 1.5 uf cap and L-PAD.
Using Martins MathCad worksheets the bottom end is somewhere between 60 and 70 hz, which seems to be pretty close to what I am hearing. I filling the bottom end with a sub.
I will have to see if I can convince my wife that a nice looking OB in the living room would be a great thing javascript:smilie('😀'). I don't think she is going to go for it; anyhow a couple of pics.
