Ok, so I'm about to have some graduation money and I'm thinking about starting my new setup. I would like to go with a single 10" this time though, and go ported still I believe. I think the amp of choice will be an orion 1200D. So let's say I have a max of $350 to spend on this sub.

My box right now is 2cubes net, I'm not sure how much more space I could get, I could go longer but I would have to go down in how tall the box can be.

so just keep all those factors in please.

SX 10

2cf is far more than you are going to need for a vented 10, and honestly that would work pretty well for most vented 12s as well.

I run a single TC7 10 in 0.7cf sealed off of 225w, and it's more than capable of matching and exceeding my front stage.

Personally I'd just run a single good 12 in a sealed box. A 10 won't offer "better SQ" if that is what you were looking for, and a sealed 12 can offer as much output as the ported 10 as well as vastly superior sub 30Hz output, and use about the same size box as the vented 10 would.

With the budget that you have available, I'd say the Avalanche 12 is a good option, as well as the RL-p 12.

If you want a really good deal, I'd also consider the Dayton Titanic 12 MKIII as well as the Soundstream Exact 12.

Now obviously those are far below your budget, but I think that they offer an exceptional bargain and performance, without the usual pricetag associated with it.

The Avalanche and the Rl-p are both capable of more output, but the Vd/$ is lower.

I didn't know you could get avalanche 12's yet. On AA's page it still says "coming soon" or so I last read. I just want a 10" for kind of a "wow factor" while also getting similar output of a 12" while cutting back on how big the box has to be, ya know?

and no it's no for SQ, we are going for output. I've had an SQ system for a while now and it's time to change things up a bit. and yes I love the T/S parameters on the RL-P and have heard good things about them. Dunno I should probably look into the AA avalanche to compare it to the RL-P.

I was thinking some about the set up, if you want a sweet ten, look at the RL-i 10, and then you could save money and run a 600D

since the RL-i is dual 4 and the Orion runs at 2ohms its a perfect match, and the amp takes less space than the 1200D
