I Hate My 15 inch cab

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.

What do you hate about it? I suppose it's possible that using it for that long underneath a 4x10 means the 15 has become over-stressed and doesn't work quite right anymore. It's a massive speaker mismatch, and a 15 will struggle mightily to keep up with 4x10s. Perhaps the speaker is just shot? If not, well... yeah, always good to test your gear before (and after!) buying...

Hi Novak,

A 10 inch and a 15 inch speaker are two very different drivers and shouldn't be compared pound for pound. A ten inch driver is usually much more musical (generally speaking), because it's moving system has less mass to drag back-n-forth so it tends to focus more on the 'upper-bass' pass-band. The fifteen incher OTOH, has a much heavier moving mass to control so tends to default to a lower frequency pass-band as a result. You can definitely EQ the fifteen to your liking, but maybe at the expense of the four ten's 'preferred tone'. Rgds

OP: do yourself a favor and ignore the above post. It has little basis in fact in 2015.

What i don't like about the cab is it kills all the attack that I get from my basses. I'm using the same head for all 3 configurations so its not that anything else changed. I'm already looking into replacing the 115 with an 810 cab to use at home and at gigs.

If I didn't know any better I'd think you were being extremely rude w/ that last post...

Sorry for coming off as terse, but I stand behind what I said.

The size of the speaker tells you exactly one thing: what frequency it will start to beam at. It has no bearing on the frequencies it can reproduce.

Now that the mixed cab police will be here in full force, someone is bound to explain better and more than me, but this has been covered a lot. But honestly, it's a distraction from the OP's problem which is why I suggested we ignore that post.

I used to play Acoustic cabs. If you're thinking of getting a new one, especially an 810, I'd recommend ditching them entirely. Get yourself something like an Ampeg 810e or a Bergantino NV610. It'll change your life immensely for the better.

You may have fried it. One of the problems with a 4x10 on a 1x15 is that that single 15 is getting 4 times the power of each 10. Since it was probably on the bottom, you may not have heard it straining.

Take off the grill and look for any damage on the cone and surround.

Agree with you on getting rid of it, you just don't want to sell a broken cab as good or vice versa.

The 410 is rated for 400 watts
The 115 is rated for 150 watts
The only time I use the 15 inch cab with the exception of tonight is which the 410. The combined impedance is 4 ohms which My Behringer head only puts out 180 watts at so i couldn't imagine it would be fired. If it is fried from that then good riddance to the cab i don't want something that craps out at %75 of its rated power.
