how come they used tons of drivers in a single speaker in the 70's?

    How come?

    I mean, I'll look at a pair of old speakers from the 1970's and they'll have 6 or 7 speakers in them.

    And, in the wierdest spots..

    Like, backfiring or up-ward fireing.

    Now-a-days we don't put that many speakers in there.

    Why did they do it back then?

    Is it sonically better?

    I think it was a combination of efficiency, since more drivers often brings the efficiency of the speaker up. The sound can sometimes seem bigger. The firing of drivers in different directions is often to create ambience, but really, that should be in the recording already. The effect isn't too bad sometimes. My modern PSB image 6T's have 3 mid-bass drivers and tweeter. Thats a fair number of drivers.

    You may be too young to remember the geologic upheavals which occurred near that historical epoch. Atmospheric density was much higher in the 1970's than today. The increased air density created radically different acoustic conditions than we deal with today. This allowed "disco" music to sound much different than it does today. It actually sounded much better at the air pressure of the time. The higher air density was also associated with horrific disasters in the textile, garment and hair care industries. At any rate, air density has dropped since the last century so things have returned to normal and fewer drivers are needed in today's speakers to move the air. You are lucky to be young enough not to remember. The survivors of that epoch are so traumatized that the actual events are almost never publicly repeated.

    Oh no! The historical cleansing police have knocked down my doo...

    I see the occasional high end speakers still using multiple drivers, including rear firing. Just depends on the manufacturer.

    I actually heard those once Miles! [​IMG]
    It's a complete waste unless you listen to classical or Jazz all the time. They image very well though.

    Bottlehead Corp. sells the high-efficiency (96dB) Straight 8 kit to complement their low-power SET amps. Each tower has 8 5" drivers and a tweeter. I haven't heard them but I've heard good things about them.
