Best 10 sub for small sealed space

This is an extension of my previous post on my smaller sealed box that the installer made. Its about .5 cu ft. net air space per sub. So about 1 cu ft. total. With the recent demise of my new Eclipse Aluminum I am thinking of changing the subs all together. I guess the Eclipses sounded ok, just not loud enough for my taste. I may have had the amp a little high for those subs, but not much when the one smoked. Yeah I know, I should have known better and kept it from clipping and so on. So what I really would like is to find a more robust sub that will work in my relatively small sealed enclosure. I do believe the Eclipses would have sounded a lot better in a larger box, but since this was a custom deal, much easier said than done. the box is within specs for the 10's.

Just for anyone with suggestions, I have a Diamond Audio 1200.1 for the subs. The subs are built into the wheel well firing up. When i smoked the Eclipse, the amp wasn't even hot. So I guess I'm looking for more of an SQL sound. Some sub that will be ok in the smaller sealed enclosure and handle the power I give it. I want it to sound good, but still hit the lows. I saw the new IDMAX's on a website, but no specs were posted. I have also thought about the RF T1's as i did listen to them before I got my Eclipses and they are rated to handle more power than the Eclipses. I don't think the Eclipses were a bad choice. I think in a different setup they could sound great, just not mine I guess. Please help, I can't stand not having bass.

You WANT subs rated for more power than you have.  To be clear:  Power handling is a MAX number, NOT a requirement. 

1200w to 2 Brahmas would be awesome. 

The 2 subs on the top of my head for top of the line performance in a small enclosure would be the Image Dynamics IDMAX, and Adire Brahma.  Both ask for about 1000 wrms each tho.

I have seen/heard both of those subs bumping off about 300 wrms but they were in large ported box's to specs, , in such small enclosures you will need more power to get the bump you want.

With the power you have they will hit pretty hard, but you will definately have to watch the amp clipping issue.

I actually just got off the phone with an Adire rep and he was telling me, which I'm sure most of you know, that they will be coming out with several new lines in the next 3-4 weeks is what he said. The Brahma is spec'd for smaller spaces like I have. the IDMAX, a very good sub as well is spec'd for a larger sealed enclosure. Closer to 1cu ft. per sub for the 10". That's almost twice the space I have. So it is a decision I will have to make, wait for the new Adire lineup, get the box re-made to accomodate 1 cu ft. per sub, or just get the Brahma Mark II and break the bank right off the bat. Tough decision I think. I have had experience with Polk in the past, and although I'm sure they've changed, I don't think I'll try that as an option. I want something that is going to last and impress as well.

Mathmatically the Brahma is a better fit. As far as sound and quality, I have no idea as no one I know has these subs, but I have heard and read nothing but good things. Price is somewhat of an issue, but not as much as the space and sound. I might have to put my blown Eclipse in for shows until I figure it out. At least my inside speakers still work:)
