Advice Please! MB121P with UL112 or UL110

According to the audio scientists on here, matching driver sizes is the way to go. But I usually play out with that combo on top of an Ampeg B-15 cab, and I dig it quite well, so I think there's really no bad answer here. I'd worry less about SPL's and more about tone at the very least.

 

The UL110 is a great sounding 110, but it's a 110... much more compressed and 'boxy' sounding than the more open 112UL (more low end).

That being said, if you like the tone of your MB combo, IMO and IME it's usually a good thing to add another 'identical' cab. That way, you get 'more of the same tone' with a more open low end and more volume.

If your heart is set on an Epi, it would the be 112UL all the way versus the 110UL for electric bass if you are looking to add some low end along with increased volume. The MB 112 in that combo has plenty of punch already IMO.

Regarding sensitivity ratings, those are usually not very accurate anyway. Very low versus very high SPL (i.e. 96 versus 103) might cause some problems (unbalanced tone and very different cab voicings, etc.), but the SPL differences you quote are probably meaningless.

 

I use an Epi UL112 with my 121P. Great conbination. I like it
almost as much as my UL110/UL112 stack, and that's saying
alot.
When you put the 121P up on another speaker, it tends to
speak more like a 1x10 box. The UL112 adds some depth to
the sound.

 

That's what I would have guessed.... the mid presence and punch of the MB112 combined with the wider, deeper, smoother voicing of the 112UL would have a similar 'feel' to it as the punchy little 110UL on top of the 112UL.

Man, the MB121P/UL112 combination gets LOUD! That will work just fine. Personally I would prefer another Markbass cab for consistency but the UL112 works great.

 

From a post on another thread, the new UL112 with the different grill cover now weighs about 34 pounds... still nice and light.

 

One thing to consider may be a Markbass Traveler 2x10...8-ohm box, same weight as the Epi and the same size as the 121H. You could also pull the head out of the combo and use the 2x10 for some gigs if you wanted. Same tweeter as the 121P. Just thinking out loud...

I was considering a mini 12 until I read somebody's came in a bit overweight...about 4 or 5lbs. Not that big a deal, but it is when you are talking 25lb printed specs.

That was here:

I agree with you, the following are the most fudged statistics in the business:

1. Cab weights
2. Amp ratings
3. Custom bass lead times!

 

Epi's weight specs were right on the money. They just changed the design a couple of months ago, and they haven't updated the spec's on the marketing material.

I again would not think a single 10 is going to get you where you want to go as an extension speaker. The Genz Shuttle cabs are nicely made, and really lightweight, but the 112 really lacked 'balls'. Given that, unless you are using it purely for rehearsals or very small gigs, the Genz 110 (nor the Epi110) would be my choice.

The Epi112UL is still quite lightweight, and they really do sound good... that would still be my call, unless you could literally get the identical cab that is part of your MB combo as an extension (especially if it had a tweeter attenuator!)

 

There is a post on the 'Perfect Bass' sponsored area on this site about someone who just got one and weighed it. You might want to follow that thread. I've sent an email or two to Epi asking for the new weight spec's, but have not heard back. I assume they aren't in a big hurry to tell the world that their Ultra Light cabs have gotten heavier

Given that a TBer weighed the new UL410 and found it about 9 pounds over published spec, 4 pounds for the UL112 seems reasonable to me.

 

I own a UL110, UL112, UL210, and UL310. I like all of them.
The MB121P/UL112 kills my UL210 LMII combo. The thing I
like about it, is that it sounds good at lower volume as well as
when its pushed. Sounds simple but many boxes like to be
pushed before they open up and sound good. Try to find a
series 1 UL112. You can always take the LMII out of the
combo and use it with the UL112. Another good combo.

 

I have tried to take my head out of my Mini CMD121P and I can't do it, but B String has claimed in the past that he's been able to do it or a friend has been able to do it. There definitely is no cover on it, though, so that's a concern when traveling with it. You'd have to get one made, which voids the warranty, so probably not the best idea.

That's one thing I really could have used, too. I think they easily could have made it removable. All they'd have to do is have some sort of strap in the back to hold it in.

 

I have both the head and combo. I didn't know about taking
the head out. My friend has one. Its VERY easy.
Take out the four screws on the back of the combo, then
just slide the head out through the top. The first time or so
it will be snug and you'll have to use both hands pushing the
amp up from the bottom. It gets easier every time.
The opening on the top of the amp is very smal. One of my
friends had a piece of steel or aluminium cut to size for about
$10. Another guy used a piece of plastic. Both used double
stick tape. It sits flush on the amp top. My opinion is that
Markbass could allow us to take the amp out. It makes no
sense not to. It makes no sense not to be able to attenuate
the piezo either. And still...... A GREAT COMBO AMP!!!
