Hi, I had the opportunity of purchasing a pair of used Cerin Vega Prostax Ps-410 speakers, 8ohms. I'm searching about reviews and technical information but nothing appear. Somebody can tell me something about it? Thanks.

We used Cerwin Vega's Mini Earthquakes as our main PA for many years when I was on the road. I was always a huge fan of Cerwin Vega's performance.

Yeah...we had an all-Cerwin-Vega 3-Way PA back in the day...great stuff.
Huge 18" bass reflex cabs...12" pairs for the mids and big fiberglass horns.

I still have a leftover pair of V-34 cabs with the 15" speaker, horn and a pair of tweeters that I used as a "smaller" PA system.
They are NOT small! And it's all 3/4" plywood construction with the gray "carpet" exterior (my cats love them )...so they are quite heavy.
I like to use just the 15" for some guitar stuff.

Sounds like the mini earth quakes we had...

Those suckers really threw the bass. I remember standing on the other end of a club and feeling the kick drum hit my chest. Best part was, they were loud, with out sounding loud.
