Thanks, that's what I've been thinking but I just wanted to confirm that it would work better.

I thought that too but I spoke with the owner of Sundownonly.com and he told me that in a sealed box the SD-2's would perform better then the SA's. I was just going off of his assumption. In the sealed box, the subs would be seeing around .75ft^3 after displacement.

I've got an AQ1200d to power my new system. I am going to either use one 10 capable of handling all 1200+ watts or two 10's that will split the power. The single sub would be something like a Fi SSD and the two subs would be Sundown SD-2's. What differences will I see in these two setups? I'd have twice the cone area with the SD's, so does that mean twice the volume?

Thanks for that. That'd really suck if that happened!

What does the QTS option offer? How does that affect it in a sealed box and how would it make that much of a difference in resale?

Does anyone have any experience with a Fi SSD in a sealed box? I've never owned a Fi but know that they're solid. I'd love to get a 10" Q but I dont have room to mount it in my truck. The downfiring box I have has 6.5" from the outside bottom of the box to the inside top. The SSD has a mounting depth of 6", including the thickness of the wood. Is there enough room to make this work? Does the SSD have a pole vent? And if it does is .5" enough space for it to perform well? Box is .95 ft^3. Sub displacement is .12". Fi suggests between .6-1ft^3 for airspace so I'd be right in the middle. Powered by an AQ1200d. Would this work?

That is extremely helpful. Thanks for posting that. I didn't think that ported was an option but damn I may have to do that. Do you have any experience with that box/company? Is it pretty solid. I've always heard to stay away from prefabbed.

LOL I was hoping you weren't going to say that.

GAH I hate when this happens, I am horrible at making decisions between two subs. Does anyone have any experience with either of these? I feel like with two 10" drivers in bigger boxes on around 1200 watts they will both be reasonably loud. Is there a way to tell if one or the other will get lower or sound better in the same size box on the same power?

This is very helpful. Thanks. If the SD 10 wants .5 ft^3, would .75ft^3 be overkill? I'd definitely be willing to sacrifice some SQ for some improved lows.

The SA 8 is sweet but it actually has a bigger mounting depth than the SA 10 does. If you look at the pictures of it on their website you can actually see that the motor is bigger, I have no idea why. Its too bad though because I have some weird attraction with 8" subwoofers, especially 8s as big as those. I didn't know DC made a Lvl 2 8". I looked into the 10" a little bit and like it alot. Do either of y'all have any experience with it? How would it do in a sealed box you think?

When you say tune lower you mean in a sealed box? It seems like sealed is my only real option if I want to do 2 subs? Does building a bigger sealed box allow it go get lower? Like if I put two 10" SD's in a box where they saw .75 ft^3 after displacement, would it be lower/louder then if it was in a box that was .5 ft^3 after displacement?

I've only looked at the displacement for the sundown's but they're only .1, so I still would have a box with more than the minimum space.

I guess another option I have is to go with one larger sub that can handle around 1200 watts on its on like a Fi SSD. So if you have some options like that, throw them out there too.

I've got an AQ1200d sitting around from a previous system that I am going to use to power two subs to go under the seat of my 2011 Silverado crew cab. Space is definitely the limiting factor here. The VERY most I can get if I go with two subs is around .8 ft^3 sealed per sub. Max mounting depth I am looking at is 6". I've been looking at sundown for a little bit and am liking the SD series aswell as the SA series. I can get both the 10" and 12" SD to fit, but can only get the 10" SA to fit. I'm hoping to get a system that sounds good and can hit the lows well. Take in to account the only other system I've ever had was an HDC3 15" in a box tuned to 39hz. I was hoping to get something that could at least match that in hitting the lows, is that possible? Throw some other brands/models out there that will work or is sundown the way to go? Thanks guys.
