Hey everyone,

About a week and a half ago I started building the Tuba HT (first enclosure I've built) and it looks like I'll be sealing it up this Saturday. But I'm having issues deciding on an amp...

First, i was going for the O-Audio 500w bash amp. But then I read about the boost that the amp gives depending on what the subsonic filter is set to. Pretty much the only negative thing I have seen though with this plate amp...

My next choice was to buy a PE 500w bash amp and then add an EQ down the road (possibly eq.2). But from what I have read, the PE 500w bash will start to roll off around 30 Hz, unless I change out the resistors.

I was also thinking of going with a Behringer EP4000 with a dsp, but I am worried that the fan will be to loud (though I could do the fan mod).

The last amp I have been looking at is the Crown XTI2000. I really like what I've seen with the Crown so far, but I've seen some tests that show (at least for the xti1000) that the output is considerably less in the 20 to 40 hz range. But I've heard that this one isn't to loud compared to the ep4000 and like the built in dsp.


So I'm pretty much stuck on what amp to go for. I may be building another Tuba HT, so I like the idea of buying a pro amp now and not having to worry about buying another plate amp.

I would appreciate any ideas or recommendations!

I'm really beginning to consider the Crown XTI2000. I can get it new for around 430 and I could add a second Tuba HT without having to worry buying another amp.

Has anyone used the Crown XTI2000, especially to power a Tuba HT? Also, what did you think of the built in DSP?

Crown xti Series are a big hit around here. You won't be disapointed. If it can deliver the voltage you need +10%, it will work fine for your needs.

Dayton SA-1000 FTW


Last thing you want to be doing after sweating over the cab is to fart around with connectors, impedance matching, additional filters, building a box for it, wondering if you'll ever have enough power...etc etc.


It is an exceptional, fully featured amp for the price and very easy to set up. Not enough dough? Then go SA-230, which can still over-power the THT, but doesn't have onboard PEQ or HPF options. The 1000 could quite possibly be the last HT subwoofer amp you'd buy.

Thanks guys for your help! It actually came down to the Crown XTI2000 and the Dayton SA-1000, but I ended up going with the XTI2000 since I was able to get it for 430 new. I hope I made the right choice! Thanks again!
