What amp for a Tumult?

[tvitarelli]

I am looking to build a sealed tumult in a 3ft sealed enclosure. I am having a difficult time finding an amp to power it. How much power do I need? I have been looking at these amps:
Adire audio DT300, AVA250
Rythmik Audio 350
Parts express 300-808.
Are there any other options that would work well? I really want this sub to shine while listening to audio and that is why I think I could use some of the lower power amps but I need advise. Any suggestions would help.

We'll have a few new amp options coming out this Fall that are perfectly matched for the Tumult...

some ideas.................

pro audio amplifiers, a good dollar per watt ratio for entry level
versions (maybe 20 - 30 cents per watt if you buy online).

Entry level;
Crown XLS
QSC RMX
etc.

You need a crossover unless you upgrade to a higher level
of amp.

I have a Crown XLS 402 powering a Adire Tempest (15") w/a linkwitz transform circuit in a 2 cu. ft. enclosure. Needless to say, the thing requires a massive amount of power, and the Crown performs well. I did have some problems running 4Ohm bridged with the amp so I am running 8Ohm stereo, but I am still able to rumble.

So I second the PA amp suggestion. Subs don't need ultra-low distortion amps, and if you need to do some active equalization like a linkwitz transform, you will need massive amounts of power. Even without the transform circuit, a 200+ watt rated amp will be all but a requirement if you plan on getting loud.

I am curious why the Hypex range of amps wouldn't be suitable, physical size maybe.

Any info you can share with us about these new amps?

Thanks

Dick,

They're suitable, but for some reason they don't sell much... The HS1000 is a great option, but because of the Euro/USD exchange rate, they're quite pricy...

We have some class D amps (designed and built right here at Adire) that are coming out. Up to 1200W into 4 Ohms, cascaded 2nd order filters (switchable bypass/2nd order/4th order), two full parametric EQ bands (+/- 12 dB gain, 0.5 to 5 Q, 16 to 80 Hz Fc), variable phase, gain, etc. Run REALLY cool (about 94% efficient), are pretty small (10.5" square OD, 9.5" square cutout), and going to be pretty cheap (under $600).

Crown K1 or K2 are pretty damn good sub-amps and are fanless so they don't make that PA amp noise
