4 ohm 2x15?

Discussion in 'Amps and Cabs [BG]' started by rexspangle, Jul 16, 2001.

  1. I mainly prefer the sound of 15" speakers but has anyone ever heard of doing a set-up with a 2x15 and a 2x10 cab together?

    I know most of you will say why not a 1x15 and a 2x10 or 1x15 and a 4x10.

    But just to think a little bit outside of the box for a minute what do you think, assuming the impedance is 4 ohms?

    Using a 2x10 and a 2x15 is fine. Why would it not be? You can get whatever sounds good to you.

    sunn makes an affordable 2x15. i'm fairly sure it's 4 ohms. no tweete, but lots of balls.
  6. Hey cool I didn't think many people did that. What I meant about the ohms was a total of 4 ohms with both cabs (two2 8 ohm cabs). Thanx for the pic EString:)

    thanx guys
  7. Sorry my fault -I noticed I titled this 4 ohm 2x15, I meant to put 8 ohm 2x15.

    As Spike mentioned, I wrote a review of my Eden 2x15 (which is 4 ohms). Thanks, Spike! My rig has a Carvin 2x10 (4 ohms) on top and it works very well. If you want a really fat bottom end - particularly out in the audience, this set-up probably beats having a 1x15 or 4x10 on the bottom (generally speaking). If you like 15s but need better mids, this combination is excellent. If you want a total load of 8 ohms, this is one way to achieve it. I feed my cabinets from a stereo head, though, so I can adjust the respective power to each cabinet. If you have a mono head, it might be a little harder to balance. Your EQ might take care of it, though. I don't know of a current 8-ohm 2x15, other than the old Kustom 2x15 I have - two 16-ohm drivers in parallel.

    One other thought: IMO you want the 2x15 to handle the bottom and to relieve your 2x10 of the lowest notes. The 10s will struggle to keep up with the 15s in the lowest octave and will have to work much harder. What I do is insert a simple high-pass filter to my 2x10 amp channel to attenuate below about 200 Hz. That way, when I crank it up, I don't have the 2x10 trying to throw its cones across the room!

  9. MikeyD that was a decent review.

    Has anyone ever considered a 2x12 and a 2x10 together?

    or would the speaker sizes be to similiar and not really make much of a difference?

    just wondering
  10. You'd have to find drivers in either 4 or 16 ohms to make this happen. Eminence makes some of their drivers in 4 ohm, but they state these are for the United Kingdom market only.

    This was a common configuration for JBL professional drives, typically with a "B" suffix. Their 130B are 16-ohm drivers, intended to be run as a pair in parallel, providing 8 ohms load.

    The JBL E-120 12" drivers are available in 16 ohm, typically used as a pair in parallel in a Fender Twin amp. Their E-155 18" drivers are available in 4 ohms, and can be run in series where a pair will total 8 ohms. Neither of these drivers are really worth a crap for a low register bass. The E-120 is strictly lead only, and the E-155 has very anemic low bass response.

    Nope...Sunn 2x15 is 8 ohms. I have it and do plan on adding a 2x10 sometime in the near future.
  12. yeah I checked out the sunn 2x15. Any reviews on this? or what do you guys think?
  13. It's loud and best suited for a 4 string.

    Thanks, I hope it was informative. It took quite a bit of time. It would be great if more members submitted reviews of their favorite gear. Copy mine and use it as a "template" for things to talk about (sound, appearance, cost, quality, etc.) for your cabinets. I would enjoy seeing more submissions. (Hint, hint!)

    I did before I went ahead with my 2x15. I was comparing the Eden cabinets. The 2x12 looked very nice, but its low end response wasn't as good as the 2x15's, and its high end was too similar to the 2x10 that I have. It was priced higher as well. I auditioned the 2x15, and its only shortcoming was in the frequency band over which I knew my 2x10 would excel. This is not to say that there may be some 12"-based systems out there that would be good. But in general, combinations of 10s and 15s seem to be the ideal for full-range sound.

  15. I'm revamping my bi-amp rig now, and replacing my pair of 6.5" mid-bass drivers with a pair of JBL E-110 10" drivers.

    My subwoofers start to roll off at 100 Hz, and this is too low for the 6.5" mid-bass drivers to handle. The JBLs will be right there from 100 ~ 8000 Hz. This will give me more punch and presence than I was getting from the smaller drivers, and I'll still have the massive bottom with the 15" subs.

    That sounds like the Plan, Man! I agree - the 10s will be more effective/efficient at getting the upper bass and lower midrange out. As you've seen in a recent thread, J. Turner likes 4x12 guitar cabinets for this duty, and it would be really interesting to hear such a setup. After a little consideration, I decided not to pursue the idea myself now. A typical 4x12 cabinet is considerably wider than my 2x15 cabinet and would look silly perched on top of it. Besides, if I put the head(s) on top of that, I'd need a ladder to reach the controls! So I'll probably stay with 10s for the foreseeable future.
