Help with enclosure... Is there a better sub for the money?

Anything better for the money?

I was thinking about going with this sub in a vented box tuned around 25hz for home theater use. I will run it with an ED LT1300. I was wondering how big of an enclosure I would need as well.

7.0t^3 tuned to 20hz looks like a decent choice but you are going to need a really large vent to keep noise below audible limits. (5"H x 15"W x 64.75"L)

Definitely a good sub but it needs a lot of space (that slot vent alone would displace 3.23ft^3 of air!!!) and a lot of power.

In my opinion one either does some big passives (3 of the 18" from AE speakers) or sealed.



This is my single biggest pet peeve with TC sounds drivers. They have great mechanical performance but their parameters suck for real world applications.

In my opinion they are best suited for smaller enclosure heavy eq applications with a massive amplifier since the T/S parameters natural suggested enclosures are never close to what works for most people. In other words they do not model very well.

Agreed - although they seem to be direct decedents of starting out their heritage with Car Audio and haven't changed in their specs much.... To me it seems they do very well in smaller sealed designs, PR - otherwise they jump way the hell up in box size for ported.... which as stated not everyone can accomodate....


I have yet to find a driver that matches them in SQ though, and I have had many.... JL's are very close - the LMS's are just that next step.... Which also tends to bring out higher levels of SPL to adjust for the lack of distortion, requiring more output then the same size higher distortion drivers...


BTW - I wouldn't say they need tons of heavy EQ for every application - that is generally a room dependent give and take.
I am running my new sealed 18" LMS with a EP2500 (1800w) in a smallish room (1800 cu ft) corner loaded, and I'm gettin very good room coupling (low end gain) which allows me little EQ to get flat down to 10hz, yet I still have plenty of headroom to boot...

Thanks Warp.

Remember that the JL W7 broke onto the scene over 10 years ago too

The LMS is a few iterations newer also.

I agree with your last statement more so because it is an 18" and it plays lower naturally.

True, I was also getting close to those results down low with my 15" TC2000 in that room (same spot) although that driver had a pretty heavy induction hump in the 50-60hz range...

No question that the JL W7 was a ground breaking product in terms of motor engineering offering great output with very high SQ all in a relatively small package, at least built to utilize a small container.... I still have the utmost respect for JL, and its obvious there are reasons they haven't needed to change their design in the W7 - still well at the top of the heap....

OK back to topic, I'm not sure one would need 3 x 18" PR's from AE....

TC recommends 2 of its 15" Passive Radiators for that sub and it will perform very well within its limits, you can adjust the moving mass on the PR's to meet the specs your shooting for....

See this post on the TC forum and check out the charts...

I started at 3 as a total guess since I did not model it. The xmax on the AE PRs is not as long as the TCs.
