Why would you choose.....>

if you lived in canada and the shipping was dirt cheap,

I think its the same amp as PE #300-793 but tweaked a bit more output, or like the rhythmic but with the remote controls thingy

 

so you are just comparing two amps, one with EQ and the other doesn't?

well seems pretty cut and dry, if you need EQ, that would be a big advantage to getting that one. If you don't need it, get the one with out.

As for the tempest in a ported enclosure, you don't really need the boost if you follow adire's specs, it should be flat, so i would get the one with out the EQ.

 

You'll 'know' by measuring the in-room performance. Your existing sub should provide adequate info for the decision.

 

bass boost is a for of EQ

by flat, i mean that with a normal amp it models flat, i only see major spikes around 60-70hz, room diffraction and other stuff thats above me.

If its a commercial generic sub, not that i am saying it is, then most likely it has internal EQ(boost) to give you more output at 30 hz.

Where is the sub located in your room? Move the sub around the room, see if you still have that 30 hz boost right in the center of the room, if you do then chances are the peaking you see is the subs fault not your room.

my theory is start flat, if you need boost get a better driver, and to tame in room response get a BFD.

 

I built the Adire alignment as my first diy home sub and was quite happy with it in a room wider/longer and mostly open on the back but not as tall as yours. I used a QSC RMX2450, bridged at first with 2400W. After several "pops", I backed off and used a single channel giving 750 watts. Still had problems overdriving it. I never used any bass boost or eq (except for running the gains a little high) and did not see any reason to do so. Stuffed it in a corner and it gave me plenty of deep bass.

I bought a 250W plate amp from Parts Express, but before I installed it I picked up 2 Tumults (the Tempest was not cracking the sheet rock) and never got around to it. But I would bet that 250W is plenty of power with the Adire alignment based on the Tempest's near-death experiences using 750W. Most plate amps also offer signal-sensing turn-on. I wish my pro-amp did the same.

If you go ported or PR'd and have the option, buy a plate amp that provides a subsonic (or infrasonic or rumble) filter, adjustable if possible. A class D/G/T/non-AB amp would be good too, but probably more expensive. 250W-350W. Auto turn-on. I don't consider the other options to be as important to the decision (such as remote, bass boost, eq, or low-pass filter). Parts Express has just this for $128 US (although it is clas AB).
