  • Speakers from an SVT 810

    Didn't know if this was the appropriate place to post this. Not sure where speaker discussions should go...

    There's a local guy selling a couple of 10" speakers from an SVT 810 for $50. Does anyone know how these sound for guitar? Is $50 a good deal? They appear to be in excellent condition.

    I tried a 70's Marshall 100W thru an old SVT cab I had a couple years ago. Not a good experience . . . very murky tone . . . unless you like that sort of thing. Let someone who's trying to repopulate an old SVT cab buy those. FWIW SVT 10's have 32 ohm voice coil, not good for much as a single speaker.

    Interesting to note Jensen suggests their MOD 50 as an SVT replacement. To keep SVT fans happy they have a 32 ohm model, also 16, 8 and 4 ohm. I have used MOD 50 for guitar and they have much more clarity than on old SVT 10". And you may be able to find them cheaper than those SVT speakers.
    This isn't the future I signed up for.

      He's selling two of them, so it would be 16 ohm in parallel.

      I'm surprised the MOD 50 would be a good SVT replacements since the SVTs are 150 watt speakers.

      But if they don't sound good, I'm not interested. Thanks.

        I've got a single 10 out of an SVT cab; no way it's 150W. I believe the reason the original SVTs were supposed to be used with TWO 8x10s is because one cab was only rated about 250W total, and risked being blown up. Maybe they upgraded later, but not in the early 70s...

        I doubt those speakers were intended to sound murky... at the time, there was no difference between guitar & bass speakers... I'd venture they were just old, tired, and soggy... I personally don't mind playing bass through a vintage "bass" cab with old-fashioned paper speakers. I get more whining about being too loud through a 50W Bassman & old 2x15 than any uber-powered sandblaster. An added bonus? I plug my Tele in and still sound awesome. The cab construction may have been a factor, too.

          Matches my experiences. To be clear, the SVT 8x10 I have sounds terrific when driven by its SVT head, all early 70's. Even more so with my 66 P-Bass. All "period correct" sounds like the good ol' days. But the SVT speakers don't sound like much anybody would want to hear when I tried the Marshall or other guitar heads. I thought the SVT speakers were specially designed for bass, what with a long 32 ohm voice coil that tends to stay in the speaker's magnetic field for more linear drive on loud notes, plus a compliance/spider that allowed a lot of movement for the cone, what's now called Xmax. As you mentioned 2x10, times four: the cab is divided up into four cavities behind the baffle. It's bad enough when you blow a speaker, and the inactive cone is pushed opposite to the working cones by air pressure in the cab, effectively an out-of-polarity driver even with an open voice coil. If a bad speaker was driven by the back pressure of seven good ones, might push the baddie's cone right into orbit! Well, pop it right out of the basket anyway.

          Having swapped in replacements all era SVT cabs, none I saw looked 150W. The most recent ones I got from LOUD a couple years back were claimed to be 75W rated, both 32 and 16 ohm versions. The point of having 8 of 'em, you could expect to use up a 300W amp plus a bit more in clip & spread that power equally over the 8, not overstressing any of them. Similar idea in a hi fi speaker article, "The Sweet Sixteen" early 60's Popular Mechanics or Pop. Electronics, probably by David Weems their speaker expert. Imagine the guys at Ampeg must have read that one. And Mr. Bose too.

          I have heard of some who loaded their SVT cabs with SRO or later ElectroVoice 10" speakers. If that cab wasn't heavy enough with the stock speakers, holey crow what a back breaking project i must be to move an EV loaded one. OTOH what a bonus for someone looking for guitar speakers, those would be prime and have high power ratings. But far as we're concerned that's legend, I've never actually run across one done like that.
          This isn't the future I signed up for.

            I have one 32 ohm SVT 10" in stock from the SLM era.
