I have a couple of questions for the Altec gurus.

I have been using Meyer Sound speakers in my home theater and I believe the drivers are descendants of Altec.

I believe when Meyer first introduced the UPA-1 they used Altec 414s as their 12" woofers and Altec 288s on custom designed horns. They used an OEM woofer and Yamaha compression driver next and currently make their own compression drivers in-house.

The woofers are rated at 101dB sensitivity with a 12.25 frame and 3" VC.

The compression driver has a 3" aluminum diaphragm and 1.4" throat.

Can anyone give me more info on the original Altec components?
