I just bought a pair of these off of Ebay. Do you guys know anything about them?
Thanks!

I don't remember the model # but the RTR's I remember were similar to those but the two dome mids were offset by two dome tweets not the single horn shown here. They were a dual 12" sealed and had some impressive noise coming out of them. They had a built in protection device that kept shutting them off when the boss was out. Not sure how that happened

They had the same wrap around grille held on with velcro and were the inspiration for my first tower speaker build. This would be about 1978.

How much did you pay for them?

The_Mox00 · 15th October 2006, 06:56 PM

Got em' for $50.00

They were a little too laid back but while messing with the crossover adjustment and general position I've been warming up to them. There's just something about giant monolithic speakers <3

Is it a dual 12?

Is that a piezo?

As I remember they were about 60" high?

The_Mox00 · 15th October 2006, 08:57 PM

Yes

Yes

and 4' tall

I wonder when they changed from two domes to one piezo, or the other way around?

It was set up with one tweeter above the mid on the left and one below the mid on the right in a criss cross pattern. Kind of goofy but that was from the days when a lot of tweeters were side by side.

What are they doing for an XO on the piezo?

4 feet tall? I must have been shorter then.

I remember they were a large and impressive tower.

Not sure, the midrange and tweeter are adjustable from the back but I can't tell you specifics cause I haven't opened them up yet.

Well get on it man

I'm always interested what the engineers do to piezos.

Can't say I'm a fan but those were the tweeters we used in the old days.

Those things bring back memories for me. I had a later pair of 600D's (with double dome tweeters) and also had a pair of ESR-15 electrostatic tweeters which I experimented with.
The woofer surrounds all rotted and I finally got rid of them. I never missed them.

Not what you would call accurate speakers relative to what's available now. They were great for playing "Crime of the Century" at ear-splitting levels though.

Cheers,

Davey.
