I'm trying to build a small sealed sub (2 cubic feet or below). Yes I know 12" in no longer in vogue but it's what I have to work with. My question is on my budget I could either get the Dayton, and have some money left over for eq, or the tc lms-r and not get eq. My room is about 15' x 15' and open.

I have a fair amount of experience with ported subs but this would be my first sealed sub. I care more about impact than going super low.

Any suggestions, I have been out of the game for 5 years and am feeling overwhelmed

Also I think I can get away with a 500w plate amp with a 25hz boost with the Dayton um12 but will without a doubt have to go with a pro amp with the tc those thing are hungry

Having EQ would make a larger improvement to SQ then the more expensive driver. The UM12 doesn't really like a box smaller then 2ft3, and even at that size it needs to be heavily stuffed to lower the Qtc, but having EQ would mean you can flatten things out anyway.

You dont need boost, just get a regular 500+ watt amp

Just asked a similar question on HTS. Audyssey XT32 any good at being the only eq in the chain for a diy sealed setup? Meaning something like the Inuke without DSP and using XT32 instead? Trying to get the maximum extension possible from the sealed sub.

The Dayton 15 HO works well in a small sealed enclosure. Here is a comparison of the Dayton 15 HO and Dayton Ultimax 12, both 500w.

But will it give me the impact I'm looking for. When something explodes I want my clothes to be ripped off. If looks like I could put 2 12" Dayton ho in 1 cu foot

To be frank, I think the HO driver is not the way to go... I suggest you go with the HF driver instead. The HO drivers can go in a smaller cabinet (15") but the trade off is that the HO driver has a lot less LF output than the HF... The HO has a f3 of about 65Hz and a f6 of about 45Hz in a 15" box. The HF in an 18" box will have an f3 of 43Hz and a f6 of about 30Hz.

I have a 12" HF and a 15" HO driver and the HF sub has tighter and lower bass, but not as much air displacement as the 15". Also, the HF drivers only need the 500-watt amp where as the HO seems to need more power. If I knew how the 15" sub would perform, I would have gone with 2 12" HF subs...

If it's not a BIG screen, it's not a theater...

Correct me if I'm wrong but the tc drivers just seem like different animals and if I need to spend more I will. I only have room for one small sub. Knowing this would ho still be the way to go?

I like the TC better if you're only getting 1 small box.

If price is not a factor and you are limited to one small enclosure then don't waist your time with the Dayton products. The TC with a couple passive radiators in a 2-2.5 cubic ft enclosure will give you similar output to an 18" Dayton HO in a 4 cubic ft. sealed enclosure. Case closed, no comparison.

If you're going to do something, do it right the first time. Post pictures wink.gif

I never said price wasn't a factor. Can someone please plot the Dayton um 12" and the TC sounds axis and epic 12" in winisd. I must be doing it wrong because the Dayton on my chart is running laps around the TCU drivers until 20 hz

It's with the LMS-R 12 instead of the Axis. These are the power levels it takes to bring each driver to xmax at 20hz in 2 ft3 sealed, and the SPL results.



UM12 + EQ makes the most sense.
