Combining a Genz Benz Neo1x12 with an older Genz 1x15

[Lincoln]

Anyone every combine these two types of cabinets? I have a Genz Benz NeoX 112 and I found a deal on a Genz Benz LS115B Live Series Bass Cabinet.

Would these work well together?

Years ago I had a GK MB150 combo amp which had one 12" speaker. I added a GK 115 8 ohm to it for the band I played with at that time. It sounded fine to me and made the overall sound fuller and louder. I have read on here before that a 12 and 15 together can cause phase problems, but I don't fully understand this. Hopefully you'll get more feedback. I now have a Markbass 112 mini combo, which is fine for my work with an acoustic guitarist, but if I ever do play with a full band again, I might consider buying a 115 cabinet to pair with the combo....

That sounds a little scary...I've got a question out to Jeff...but I thought I'd throw it out here as I might be able to get quicker responses...

I used an Aguilar GS112 + Mesa PH115 together once with mixed results. Basically the 112 just got overpowered at louder settings. I'd recommend from personal experience to find which you like best by itself and pair it with a twin. I'm not a huge fan of mixing driver sizes anymore.

2 votes of scariness....deal might not fly...anyone else with good news?

I have used Mesa Scout 12 and 15 (both 4 Ohms) and Epifani UL2 112 and 115 (both 8 Ohms) with good results. The physics dictates that a 2nd IDENTICAL 12 is the safest match, however. If you proceed and 1/2 your amp's power is enough to blow the 12 then you should listen for signs of the 12 crying if you push the stack hard.

hmmmmm...

the 1x12 is rated at 300watts at 8ohms...the 1x15 is rated at 300 at 8ohms...

The Shuttle 6.0 amp is rated at 600 watts at 4ohms... yes? no? maybe so?

[Lincoln]

any other advice before I pull the trigger on this? Anyone from Genz out there that could answer this question?

I often stack my Markbass CMD121P on a Bag End S-15. I've never had any problems.

Displacement limited power is your concern. The average 12 is displacement limited to around 100 watts, the average 15 closer to 200. It varies by driver obviously.

The big reason not to use a 12 is that you need about 50% more xmax to achieve the same displacement as a 15.

What kind of amp are you running through it?

The Markbass is a combo amp.

So rather than having more power I may end up with less power because if I pushed past a certain point on the amp I could blow the 12?

This is the same combo I have and would like to do the same thing. This gives you the full 500 watts of the Markbass if the Bag End is ohms right?

That's the theory.

If you're using a shuttle 6.0, I don't think you would be likely to push the 12 past Xmax with the 15, as long as you are responsible with the volume knob and bass eq.

The shuttle 6 is a good fit for two Neox112's in my opinion so chances are good the 15 would be fine.

That said: I don't see why you would want to put bologna on a steak, tonally.

In practice, there will be no problem.

Adding the 15 will increase the radiating area and the net displacement so you will definately see a real gain is SPL and low frequency extension.

Not sure I follow? What do you mean?

[rpsands]

I mean, the Neox112t is a cadillac, filet mignon, etc, and the Ls115 is a chevy nova, bologna, salisbury steak, etc.

Mixing an average cab with a superb cab is a good way to crap on the tone of your superb cabinet.

I'm fairly amp dumb - what does that translate to in practice on the stage?
