What speakers for this old Sunn amp

    I just picked up my bass after years of it collecting dust :( and the only amp I have left is an old Sunn Concert head that I don't know anything about.

    This thing has little to no information on it, about all it says under two jacks on the back is Max output power 200W. The front is simple with 4 knobs, two inputs ("brite" and normal, a red brite switch, and the power switch.

    I'm thinking about picking up a cab that will work with this amp OR in the event this head turns out to be fried I can use it with something else in the 200-400W range.

    There is no info that I can find about ohms...nothing I could find by searching except one pic that has this head sitting on top of a slave head and an assortment of cabs but I'm pretty much lost with this thing.

    What would you look to pair this amp up with?

    Something efficient like a Schroeder 15L

    Here is a pic of this old heavy monster...it feels like 40#'s.

    That pic? ;)

    That's my rig.

    My concert bass gets hooked up to my 4x12 (8ohms) and my 2x15 (4ohms). The slave amp runs the 4x10 and 1x18 (both 8ohms).

    I found an old ad for my amp, and it and the slave amp where both advertised as being 200 watts @ 2 ohms... I've had absolutely no problems running my amp at 2.6 ohms. My amps run pretty hot though, no matter what ohms they are hooked to. I always keep a fan blowing on the back of them when I'm playing full volume and it keeps the transistors and heat sink in back at room temperature. I also never push my volume past six on the Concert Bass. On my amp, it clips just a little with the volume at 6, but from what I've read, there are smaller transistors in the amp that are MEANT to be clipped. It was an attempt at simulating tube overdrive. I will say that clipping this amp does sound pretty damn good IMO. But I never put my amp past 6. It will get louder when it hits 8 though. Don't let the 200 watts fool you, this amp is loud.

    Here's the old ad I'm talking about...

  7. Well, I'm not playing in a "normal" band setting. My band is just drums and bass. No vocals, no guitars. With all that stuff I use, we're just as loud sometimes louder than the bands we play with that have half stacks for guitar(s) and 6x10's or 2x15's for bass which is exactly where we wanted our volume to be when we started this band.

    Now, if I was in a band with two guitar players... I'd probably just use my Concert Bass with the 4x10 and 1x18. But, I've never used any combination of my gear in a full band setting. But I'm certain the Concert with those two cabs would be loud enough. I use that setup (CB>4x10/1x18) when we practice most of the time and it can be heard very loudly over my hard hitting drummer. The slave amp and other two cabs rarely get used at practice, just live.

    It sounds like I can't go too wrong with a 4X10 to start out with.
  9. No problem.

    A band I saw last year, just drums, one guitar, bass, and vocals... Their guitar player was running through a full stack with a tube amp. Bass player was using an older 200 watt Peavey solidstate amp through an 8x10 that had a couple blown speakers. He could be heard clearly over everything. 200 watts can be very loud with the right EQ settings and the right cab(s). A 4x10 sounds like a great start.

    If it was 1973 it would be setting on top of 2 Sunn 118 cabs with my 4001 JG leaned against them.
