I don't know if this will work! Please advise?

I have an Ibanez Promethean P5110

It's 250W into the 8ohm 10" speaker attached

I want to pair it with another cab to get the full 500W from the amp.

Someone has offered me a Markbass Traveler 102P at a very reasonable price. 8ohm, 2x10.

Will this work? I've never heard of anyone pairing a 1x10 combo with a 2x10 cab before!

I need to let this guy know in the next couple of hours or he'll sell the cab to someone else

For a good match the 210 must be 4 ohms. If the amp can't push the resulting 2.7 ohm load don't bother, get a matched 1x10. And forget the watts, they don't matter.

Yes it will work but you'll still be limited to whatever power the 110 can take before farting out, which likely isn't much. You'd end up with a 310 rig, you'd still have to keep a lid on the volume knob but should be enough to play a gig if you stand the 210 on end and put the combo on top of it. When the little 110 starts to distort, turn down.

If you're SURE the internal speaker is 8 Ohms, it will work fine. But how it will sound is anybody's guess. Probably pretty good, but there's no way to know without trying it. And as Bill said, it needs to be 4 Ohms to really work well, so the speakers all get equal power. Better to get a 1x10 at 8 Ohms, really.

The amp has a minimum impedance of 4 ohms.

I'm not entirely sure I understand where the 2.7 ohm load has come from.

Basically, I need something that's going to get me a louder sound than the 1x10, without going for something crazy heavy.

If there's an output on the amp for an extension cabinet, then more than likely it will work. You will probably not be able to crank to full power before the attached speaker hits its limit but your volume should increase simply based on the fact that there are more speakers. Tip the Markbass up on end for a nice vertical stack and I'd say you are in business.

If your head can handle a 4 ohm load then two 8 ohm cabs will work perfect so make sure the 102p is the 8 ohm version and you are good to go. The MB should sound better than your original 10.

BTW what is a good price?

Evil Undead · #9 07-25-2011, 02:08 PM

What about adding a 1x12 instead of a 2x10?

Got a pretty good offer on one of those as well

The 2.7 is the result of pairing the 8ohm internal speaker with a 4ohm 210 ext. That would be the best combination as all 3 speakers would be getting equal power but that impedance is too low for your amp so make sure any ext. cab you get is 8ohms and yes, it's always best to pair it with something identical like another promethian 110. The markbass cab will work, it's not the absolute best choice.

Trouble is, the 10's in the extension cabinet will receive half the power that the built-in 10 will get. That's why Bill said to use a 4 Ohm cab, but the amp probably can't handle it.

Anything other than another identical speaker is a crapshoot, might sound good might not. Any ext. cab will make it louder. Some people equate louder with better. Bring your amp and bass and play it with whatever you're looking at buying.

Evil Undead · #13 07-25-2011, 02:21 PM

I'm confused haha!

So basically anything other than another 1x10 wouldn't be ideal?

The identical Promethean is on back order, at the earliest it's going to be October. I have a larger than usual gig in September that I need to be a bit louder than usual for...

Evil Undead · #14 07-25-2011, 02:23 PM

What about another 8 ohm 1x10, but from a different manufacturer?

dmusic148 · #15 07-25-2011, 02:23 PM

In my opinion, if you need some REAL volume, get a 4 Ohm 4x10 and pull the head out of the case and use just the 4x10 for loud gigs, that'll pin your ears back.

will33 · #16 07-25-2011, 02:27 PM

If it's just for one gig I'd see if I could borrow, rent or buy and return/resell a big cab. Disconnect the internal speaker in the combo and just run the amp to the larger cab.

Evil Undead · #17 07-25-2011, 02:27 PM

Hehe, I'm sure it would!

But I'm looking for a lightweight solution only as I have back trouble

makes it a little more difficult.

Oh, I didn't think of disconnecting the internal speaker... That's a damn good plan
