Choosing an SQL subwoofer for a sealed box.

[Miguels]

The only other concern I have with a sub like the Fi Q, is that it's only rated at 1500W RMS. Not that I don't think that's enough but even with the extra cooling options it doesn't look like it would handle 2000W safely. I'd really r rather not have to get another amp. Thoughts?

you are worried over something that no matter what sub you get you are going to be running the risk of over heating the coils.. sealed boxes are really bad with cooling of the sub.. if you have the room go ported and im sure the Fi Q can handle that amp. plus its a hifonics rated at 2000 so it should be around the 1500 rms you will get 2000 out of it if you get lucky

That's true, but more probable to happen pushing higher than the rated RMS, no?

I could probably fit a ported box, but traditionally in the past I've always been happier with sealed. Rock and metal are usually much better sounding in a sealed setup so that's what's keeping me to a sealed.

The amp is Hifonics top tier line and it's CEA certified so I'm sure it's pretty close to the posted specs.

Reading most of these posts it really looks like most of the subs that are being named are more for ported applications, not sealed.

For SQ, as long as you take your time with the car, and the box, you can get a totally flat response out of almost anything in a ported enclosure. 90% of the work on an SQ setup is enclosure when it comes to subs.

If you're looking for a good SQ sub that is going to handle 2000 watts sealed, I'm not sure that you'll find one. Most of the time, especially "in car" you dont need to run that much to one sub to get a flat response, especially if you're not running at least that much to your interior speakers. Get something like WinISD and play around with box design on the subs you're looking at, and look at the response curves. You'll get a pretty good idea of what the sub will do. The best way to get flat response is to take a sub, put it where you're going to build your sub stage, and play it in car to measure your peaks and valleys on frequency response. Then you can tune the box accordingly to get it flat.

An SSA Icon or Xcon will sound really good in a sealed box (on the bigger size).
I tried them both in sealed enclosures, and in ported ones. My personal taste : ported, because of the increased outpup

I found the Icon was a nice sounding sub, but the Xcon has more punch.

Fi Q or AA Havoc are on the same level.

All of those are good choices on that amp. Don't be afraid. You can always turn the amp down if you feel ther is too much power !

Honnestly, I can tell you I'd rather get an SSA sub, just because of their customer service. They all will ask you to wait for a month, as they're built in the same factory in Vegas.

Well even with a flat response, isn't it true that a sealed box will still be more punchy and fast paced to handle quick bass notes in rock better?

I will take a look at some of these subs in ported boxes. The other thing I realized also is that I can run my amp at 1600W at 2ohms. So if I go for the Fi Q I'll run it that way.

I know what your looking for, i am kinda in the say situation exept my sub set up with a T1D212 the box is tuned to high with to much power to it. So i want to to sealed as well but run 2 12s at about 2000 watts off a T1500 in 1 ohm. Looking at the FI Qs myself.

Nah, plenty of SQ people use ported boxes. You just have less wiggle room when it comes to designing a ported box than you do a sealed one.

The Fi Q is a very sexy sounding sub in sealed. It does it all. It was my favorite sub until I traded it for an XBL^2 XXX

I'll have to play around in WinISD a little and see what I can come up with.

By XBL^2 XXX you mean the older ones and not the current models right?
