I have two pamphlets from the 70s Heil Sound. first one:

The early Heil Sound systems had a profound effect on my loudspeaker collection.

In the early 70's I got two blown up Altec A7-500s from a local band for $200. I refurbished them with stock components and they sounded awesome.

I listened to the Heil Tr-ax system used by the James Gang at a fairgrounds concert. Sold my rebuilt A7s for $400 and got a new 1975 Klipsch LaScala including shipping for $425.

Later I built several systems based on the Heil Citation. I still use/have these in my near field kit.

Hello turk 182, in the above pix I have the EV ST350A tweeter, EV SM120A horn with an EV 1824M driver, and two EV 15B woofers. The bass box is sized as a 7 cu/ft center slot ported tuned at 43Hz. Similar to the EV TL606B with 15Ls. Mine would be a TL506B that EV didn't name, per DBKeele.

The speaker has 107dB/W so the pair is 110dB/W. The 15Bs are Pro-line.

As for my LaScala it has always been the center channel for my modified Klipschorns, I also have a pair Belles for rear surround duty. I have an EV 15B in the LaScala, also I sawed off the top portion of the Klipsch box, added two pcs of 3/4 plywood to the outsides of the bass horn and changed the mid horn to the EV HR-90.

I also needed a Large horn and BR sub ;)

Alright, YOU need to post pics of your whole system! That center channel is WICKED!
 
Hello BP1Fanatic, I could not get the pix into one post due to size? no problem.
