This might sound like a dumb question but can you tune a sealed box?
for the most part, nope, after a certain airspace you see miniscule changes. You can get slight shifts in the low end while sacrificing some with a much bigger box but its nothing to write home about at all. Most people cant even tell the difference. Honestly you are literally just stuck with the frequency response your vehicle acoustics give you and thats it.

As said earlier you can EQ but thats not really optimal,

No. Porting usually gives you some flexibility to shape your output once you know what effects the vehicle acoustics factor in. You can buy some adjustable length round ports and play around to dial it in to your liking.

I can vouch for the Brahma being a great sounding and capable driver. There's a couple of the originals around this area and they're really great. W7 is also nice but MSRP is a bit outrageous I think. Either of those are 1000W subs. The IDMax is more of a 500W sub but if you're not going for more power than that they're very nice in their power range. Add Dayton to the low power list too. I've only used their mids and tweets myself but there's enough guys swear by Dayton subs that I'd feel safe in recommending them either.

Yeah I'm looking for something probably around the 1000RMS range. Audiofrog, W7, and Brahma are looking great right now

Unless you can find a great deal on a W7, I’d get the frog or adire. For that power, I’d lean more towards the adire. The frogs do like small boxes which is a plus though.

i ran my brahma sealed in quite a few different enclosures 1.5 to .65cuft. .65 to .75 sounded the best, still plenty of low end i was impressed

Was your the 12? I want to be able to hit the notes on rap songs but still sound really good and not overpowering. The bigger sealed box you go the more lower end youll get?

yes single 12".... anything over 1.25 she bottomed out way to easily on the lows...not much difference on the low freq. with a bigger box vs smaller. sounded way cleaner/accurate 50hz+ in smaller enclosure

If you’re serious about getting a GB, look at DIYMA as they often have used ones for sale for a fraction of that price. Where in the world are you seeing the Frog at $899??

Based on the choices mentioned in this thread, I'd say W7 for the win....... it will beat the XBL2 /Adire woofers. The W7 has been a benchmark SQL sub for a couple of decades now. They are pricey though.

I'd personally go for the Ultimax and save some cash......... true mirrored spiders, low Le, shorting rings.......that's a very refined sub at a reasonable price.

And that's kinda the problem. It got it's reputation when competition was weaker and now that competition has gotten tighter they haven't adjusted the prices. Amazing product but id' rather have a Tumult/Brahma that's 90-95% as good for a fraction of the price
