There are so many threads where I could have posted this question, but this one seemed the best. I've read with interest all the great threads on the GK MB210 and its various issues (lining, bracing, boominess, etc.). We purchased one used for a great price and it's perfect for our application: my 10-year old kid needs a light, loud combo amp to schlep to and from rock band class. The unit needs to be cheap, fit in the trunk of a Chevy, needs to be something he and his mom can lift/carry. This thing fits our needs... for now.
This question is about crossovers.
1) Is there a passive crossover in this cab between the amp and the 10" drivers & tweeter?
Stupid follow up question:
2) Would it be possible to add a passive crossover while running the GK 115MBE as the ext. cab? I know you can use the 115MBE 8ohm cab as the ext. full-range (and I've read why this isn't a good idea). But could you include a passive crossover to send higher signals to the 2x10 and lower to the 1x15?
The 10-year old wants an ext. cab for this thing quite badly. Looks like a patient dad could snag one used for about $200. So I am wondering. I know it wouldn't be perfect, but a cheap 500w dual-cabinet rig could be perfect for this pre-teen rocker of mine.
Many years ago, I used a 2x10/1x15 bi-amped rig with a variety of heads (including a GK, but that wasn't my favorite). I realize that was an active crossover situation, but I am wondering if we could modify the MB210/115MBE unit into something similar.
This is obviously related to mixing cabs. If I understood all the threads, the biggest problem with mixing cabs is when they are full range; when they are programmed with different frequencies, it's less of a problem. This was certainly my experience with the 2x10/1x15 rig I had back in the day. It sounded like crap full-range, but it was the best when bi-amped with highs going to the Hartke 2x10 and the lows going to my Boogie 1x15.

P.S. FWIW, the tweeter in our MB210 isn't that big of a problem; we've learned that you need totally different EQ for use at home during practice and in a band setting. We turn the tweeter off at home, but the buzz is not nearly so noticeable in a band context. The master volume needs to be much lower in the living room, too.
