I currently have a yung 500w rms plate amp pushing a 12" kicker comp from around 1998. I also have a 10" Martin Logan that has 100w.


What I want to do is get rid of the Martin and go to a dual 12" sealed. I only want to spend about $200 on subs and enclosures. I would go with dual 15's but from what I can tell that's more than I want to spend.



Here's what I'm thinking so far.

I need to get down to 20hz. That's my goal. My current setup gets to 24hz with plenty of umph. But the 12" only is rated to get about 26hz, the 10" is only good to 32hz. Also the current box the 12 is in is small.



2 subs and 2 boxes. Also has to come out to 4ohm after wired. I need to have two subs due to my mains in my room are crossed over at 120hz, when I take the 10" out the bass comes to the left. I don't want to be able to place it.


Under $200 budget

the infinity 1262w is a dual 4 ohm, series wire coils, parallel the drivers for net 4 ohms.


$60 on amazon and folks seem to be pleased with it. there are a few builds around here, but i don't recall links to them.

"But the 12" only is rated to get about 26hz, the 10" is only good to 32hz."


there may be a bit of misunderstanding there, as subs are really 'rated' that way.


also, a ported cab would get you a whole crap ton more spl 8-12db around the tuning frequency (depending on size), but the build would be slightly more complex.


here is a pair of those drivers in sealed (5 cubic feet) vs. ported (7 cubic feet, 21hz tuning).




most rooms will have some gain below about 30hz or so depending on the size of the room, but that this is a decent rough comparo between two configurations that might work for you.

also, +6db is about what you get if you double the number of subs and amps, so the difference shown above if fairly large.

I'm lazy and don't want to build boxes, also my wife would say something with 2 5 cubic ft boxes.


Buy those subs look good and they say bsealed Is recommended as 1.25cbf. Which is a easy box to find.

check the TS-W3003D4, they just came out and cost only slighly more than the TS-W310D4.

They have a bigger magnet and a rubber boot, otherwise the cone and surround are the same.

Rated power is higher, 600W rms each

I have 2 of these new ones in my Isuzu Trooper, and have replaced the TS-W310D4.

I do feel they go a bit lower. I have them in an enclosure bigger than recommended, but I get pretty good low end.

It hits MUCH lower, compare to my Polk PSW505 12", which is a "HT" sub.

For around $200 you can get 2 of these new ones and an enclosure....


Also, according to the specs, these should go lower compared to the Infinity (?)


Left is the TS-W310D4 Champion 12", right is the TS-W3003D4 Champion PRO

1.25cf is for a car sub box. Home use needs a bigger box because you don't get all the Cabin Gain like you do in a car.

Now I can't decide between the infinity and the pioneer.


There is the 20hz (pioneer) vs. 23hz (infinity). But what they state and what they do are probably different things.


The box I'm looking at is 1.5cbf


The infinity max size size sealed is 1.25, in a car though

The pioneer is 1.75cbf. In car, optimal 1.5.


Which sub would sound best in a 1.5 box in a house? Fairly big room, but like I said the setup I have now works fine, just want to have the under 25hz better and a more even blend than what I have now.

I can, audyseyy sets it at 150hz, which I mainly do to location of one speaker not getting great bass in the location it's in, and that location cannot change. I change it to 120hz, any lower I do start to lose the upper bass guitar notes quality.


My one speaker on the right is about a foot from wall just like the left, but it has a open hallway and just doesn't have any room or wall help for bass. My center, left and right are all the same speaker, (BIC lcr fh6 ) the center audyseyy sets at 80hz.

There is another thread here (or Home Theater Shack) that used the Infinity 1262 so you could see what box he built. You need to forget all about car audio (
) if planning a home use sub. Box size is calculated using Winisd and the speakers specs from the manufacturer. I have a 1.25cf sealed box you are thinking of in my truck but it has the Infinity Kappa Perfect 12.1D instead of the 1262.

Nothing larger than a ten, probably an eight. In a small box you can go low, or you can go loud, but you can't do both.

+1. Look at the SPL charts here, which compare response of small cabs inside of a car versus out:

Car audio uses small sub enclosures because you can. Home audio doesn't because you can't.

I'm using a 12 in a less than 1cbf right now, it's insanely loud and clean.

Figuring if I do 2 with bigger boxes and they go lower, I will get a better low end response.


If my memory from my old age serves me right, small sealed equates to sq, bigger equates to better bottom end but sloppier.


I guess what I'm really looking for is someone to say those pioneers or infinity's are junk or here's a better brand that you missed that will do exactly what you want.


Looking at all of svs's subs that are sealed they are around 1-1.8 cbf.

If you have a fairly big room, I'd go straight for 15s or 18s and forget the 12s. I have a dedicated room that is 14x20, I went from a couple 12s to dual 18s (sealed). Absolutely no regrets what so ever.
If you really have to stick to 12s, I'd go ported and get the most output you can out of them.
