I Hate My 15 inch cab

I've owned both the Acoustic B115 MkII and the Acoustic B410 MkII and I gotta say I agree with OP. And I have always leaned more towards 15s. The B115 was lacking in a lot of substance and sounded real boring brand new. I traded it back into GC for the B410 and it was light years above the tone of the B115. However the B410 was a beast to move, even with casters. I think mine was around 91lbs. I could also never quite coax enough volume out of it to compete with both of the guitards 4x12s. I've since moved on to two Schroeder 15PLs and would never look at any other cabinets.
 
The weakest link in your tone is the speakers. The best bass, pre-amp, pedals, cables and all the other stuff in your signal chain can be the best. But if the speakers are not very good at reproducing your sound then you will not benefit with having that grate signal chain.
Always spend the most time and or money on getting good cabs.
 
Try CL. A quick NJ search reveals a few cabinets that'd kick an Acoustic's ass. What's an Acoustic 810? $400? There's an Ampeg for 5, and an Avatar 410 for 4, both of which would be miles better.
 
I love my 410 115 stack, but if I ever gave it any real juice the 15 would quit!
Sorry the 15 didn't do it for you anymore, I tend to like 115s more than 410s and a lot of them really rock!
If you decide to get another 115, whatever brand, make sure the power handling is close to your 410, preferably higher, or get a head that's stable at 2 ohms and have an 8 ohm 115 and a 4 ohm 410. It'll protect it better.
As you can see getting another 410 might save you a lot headache. I like my rig enough to wrestle it, but trust me, my 210 115 rig sees a lot more play than the other one.
 
Not arguing, just asking (got no dog in this fight):

Am I correct in thinking that the top end response of 15s _generally_ tends to tail off at a lower frequency than 10s? Apart from the voicing of the box they're put in--the speakers themselves, IOW.

It depends on the cab. The Ampeg 4x10HLF has subwoofer like lows. The old Mesa Engineering Roadrunner 15" cabs are midrange monsters.

I ran a GK MB Neo 1x15 and a GK MB Neo 2x10 together for a while. I thought they sounded good together, but apart the 1x15 sounded pretty boomy and dead. Now I'm running two Fender Pro Neo 115 cabs and they sound great. Either as a single or both.

do yourself a big favor and ditch the 115, stay away from the acoustic 810, and buy the best cab you can afford. it makes the world of difference. buy used, you will save yourself money.

personally, i didnt think much of it when i had my acoustic 410. i thought it sounded great. till i got my schroeder 1515l. the difference was night and day, immiediately noticable (both on and off stage). bought it used at a deep discount. now i dont think i could go back to "budget" cabs. you dont have to go schroeder, but something "better" is well worth the money.

edit to add-
if you like the acoustic 410 you have, and just need more, buy another acoustic 410 of the same model.

To the OP,
FWIW------ I had the setup you are speaking about. The original "Guitar Center" Acoustic brand 4x10 and 1-15. The tone and efficency of the 1-15 was less than ideal to my ears. The 4x10 was much better. Both are available used at GC from time to time. Trade the 1-15 toward a 4x10 and life will be better for your ears.
I like 15" speakers for bass, but not GC Acoustic 15 speakers.
YMMV
 
If you're not happy with the Acoustic 1x15, and you confirm it's not broken in some way, it does sound like getting rid of it is the right way to go.

...and figured I'd use the 15 for practice at home. I plugged it in and immediately hated it. I can't believe I have owned this so long with out using it by its self.

Just a reminder, that sometimes things that don't sound so hot when played alone at home work pretty well in a band setting. Not saying that's the case here, but just something to consider. You could try just the 1x15 during a band practice just to make sure (before you unload it).

I've been very pleased with my Bag End 15s, but that's neither here nor there...
 
so years ago i bought an Acoustic B410 which I loved. So a year later i bought the matching 15 inch cab to add to it. For about 3 years I either only used the 410 or the full stack but the 15 was never played alone. Recently I joined a band and brought the 410 back and forth to practice and I couldn't figure out why I liked the tone so much more when playing with my band. So this week I left my 410 at my drummers house and figured I'd use the 15 for practice at home. I plugged it in and immediately hated it. I can't believe I have owned this so long with out using it by its self.

I play an old school Acoustic 136 with a single 15". It has a replacement EV speaker that totally revamped the sound(weighs a ton). The reason I post this is because the speaker make and style has as much to do with the sound quality as the width of the speaker. Also, a really well designed cab makes a world of difference. Sometimes cabs are nothing more than a cube with a speaker screwed to it. Those cabs make the best amps and speakers sound scrappy.
