Folks I joined just because of this thread. My first set was in my '68 Camaro 327... Mindblowers? Yes, they're were that good. Everyone in school knew it was the best system in school. It was always the focal car on scene for tunes hanging out or just cruising.
We had no high power amps, 12" subs, tweeters, woofers or cones. It was a 20 oz magnet overdriven system or nothing if you didnt have a set of Tenna's MindBlowers. I had several sets through into the 80's and the MindBlower II sets were a bit clearer though did not the driving force the original sets had. Jensen Triaxe's came out in the mid to late 70's and were good sounding and they would rival sound, though not thump. MindBlowers would rattle the hood on every car I installed them in.
In the the later 70's I wound up installing around 50 different stereo units for friends and a couple of car lots that wanted clean professional installs and no muss systems. MindBlowers were my choice when folks would let me and never was there a complaint. The Jensen, Craig and Pioneer systems were always so, so after an install and the buyer had twice as much in that system.
For the cost They still could not be beat today. In 2013 I set up a show boat for the BassMasters Classic Expo in Tulsa, OK with Kickers latest version, 10" sub, 1000 amp, 6" quads, quad tweeters and four 6" cans on posts, all driven by a very dependable Sony 910 head unit for outdoor use. The sound was very good, though I really think today a set of original MindBlowers would have rivaled the system with a good head unit behind them.
Over the years we have installed head units and speakers by Kenwood, Clarion, JVC, Sony, Pioneer, ProSpec, Maxxima, Panasonic, and many more newcomers. We have done thousands of head units since those high school days and obviously feel we have some limited feel for what works.
I did a search looking for Tenna and this thread popped up. I think enough of the Tenna MindBlower systems still today that I would install them in what we do now. And we install about 200 stereo units annually today, opting for Sony 910 as we bought a years supply before they ended production, and Kickers with a Tweeter set for marine use. Nothing has had so much punch for the bucks spent then or now.
This thread obviously won't die and it shouldn't.
