GK 115MBX Cab Photos

This was my Christmas present from my wife and children. The goal here was to find a cheap, used cab with decent tone to leave at the main church where I play bass. Cheap because ownership will probably default to the church over time, and others will likely use it as well.

The cab with the 15" driver removed. It's screwed in to the baffle with regular screws. No surprise as this is not one of GK's top of the line cabs.

The driver is GK's 200w 15" paragon. No surprise as that's stock.

The tweeter which started to make a crackling noise on the 2nd gig. Good thing I don't like tweeters on, and the replacement is only $16 on the GK web store. I haven't decided if I will replace it.

The bracing inside is largely from the large V brace that spans the sides, back, and baffle. Some bracing is provided by the two corner ports on the bottom.

The jack plate and crossover. Perhaps not a true crossover, but really just a simple HPF to the tweeter using a capacitor. Plus a switch to turn it on/off. The driver receives the full range. Calculating the capacitor value, the tweeter receives frequencies just over 4k. I doubt the driver does much above 2k.

There was no stuffing inside, just bare plywood (good grade too). I added stuffing and tested. Ended up with a small strip on the front bottom that sound the best to me. I know that some here like to say the factory knows best, and they certain do. But their parameters to decide something subjectively is not the same as mine.

I'm only deciding what sounds best for my ears. The factories are deciding what would sound best for a majority of buyers, plus how much would it increase the cost to manufacture. Since I already had the stuffing, and this is weekend time, I'm not worried about cost.

So I've been playing it for over a month now, twice a week. It's sounds pretty darn good from something not much over $100. I use a Markbass LM250 amp with it that's rated for 175W at 8ohm. There has been some talk about the cab's low power handling at 200W, but for me, it's not a concern. It would be a concern if someone brings their 800W amp head. But they would be overplaying, volume-wise, to blow the driver.

This setup has made me into a SpeakOn praiser. Far, far better than 1/4" jacks.

Hopefully I’m not going to be smacked for bringing up a ghost but I figure it could be applicable here rather than making a new thread.

OP if you’re still around, be glad to hear your take and anyone else obviously would be welcomed.

Curious if this cab is indeed of a quality enough to merit swapping drivers as I’ve got an empty one for free and I’d like to know if it’s a complete no and I’d be better off leaving it just as empty or putting a driver in it.

Driver I have on hand is an Eminence Kappa 15A.

Thank you and apologies for violating protocol by bumping this but I figure it beats creating a new post that’s detestable.

Be well just the same.
