Im going to start planning the modification of my HT room subwoofers. Currently TC2K 15" ported subs

Costs are similar so which would be better?

I require solid performance down to 15Hz and maybe below but more importantly I want very good performance from 30Hz to 70Hz. My TC2Ks have that peak in the 50Hz range that is hard to control.

Up to 11 cuft boxes are allowed.

My biggest amp is my FACE F1200TS (1000W/ch) , it would be nice to not need more power.

Go with the dual 24" av15 + pr's

more output, less power required, no need for eq

boost down low, very similar sq.

You can run one off each amp channel

Still going to want a high pass though.

Penn ,

I agree with Warp. Go dual AV15's with PR's.

My next project will be upgrading my dual sealed AV15's to 24" PR enclosures.

Not that I am unhappy with the performance I have now but just to have another project lol.

You should be able to put the AV15x's in your existing TC2k boxes.

Anyone able to throw a quick model showing SPL/FR given 1000W to each 15 vs ~1800W to the single Mal-x Gen II (Penn's options with the F1200) to reinforce this?

I'm interested in this as well as I'm at a point where I have a Mal-x with no box yet, but some initial testing with some car subs in my tiny listening area puts a nasty null at listening position, so I'm worried about a single sub not fixing this.

I can't add another EP2500/Mal-x, as I think it is crazy that I need to dedicate one 15A for one speaker. Two is just not...well...it just isn't going to happen.

You can put 2, ep2500's on one 15A circuit. I can't promise that you won't trip it while testing sine waves at clipping, but I've heard of people doing that with success. A 20A circuit would be better though.

The 15's with PR-s can be significantly more efficient than a sealed Mael-X

Go apples to apples, a Mael-X with dual PR's can also Kick some serious A$$

Correct.... apples for apples....

Penns thought process would be leaning towards cost being apples to apples here though...

The cost for a Pair of the Dual PR Mal-X would be a good $500 more, but likely give you a good deal more output....

Usually performance is prioritized higher on Penn's scale though...

Does this imply the Mael-X with PR's will outperform 2 AV15 with PR's using his Face amp?

I agree 100%, but he did stipulate price....

Not exactly sure on room size for Penn there.... But I will state that the AV + PR's had some stupid crazy output, no joke here... 2 of those would be more then enough IMO, and the cost would be lower going in that direction.

I have absolutely no qualms about comparing SQ between AV PR and my F112 side by side, it was extremely clean but with what seemed almost 2 times the headroom.... Very Very good sub...

Nothing lacking in the SQ or performance with the less expensive route in this particular case, and I have a few Mal-X's in my house...

One of which I smoked just the other day.....

Got another on the way already....

Just wanted to post a couple quick notes. The AV15H and dual 18" PR's with 2100grams gives about a 17hz tuning and is preferred for the home theater alignments. The AV15X and dual 1600gram PR's gives a tuning about 21hz and gives a little more efficiency in the 20's. This is the one I brought to Warpdrv's GTG.

I'm putting together a package deal with the woofer, pair of PR's and either raw MDF, black textured, or veneered cabinets. The black textured will be the same as the one I brought to the GTG.

The package price will give a significant discount.

Very cool, can't wait to recommend it to people in the Subwoofer section

Also, that sure is a d*mn nice photograph of the sub... seems like maybe I've seen that somewhere before...

lennon_68's photobucket

Are we going to be seeing these on subs any time soon??

Nice John....

I know you brought the AV15X to my house, and it was an amazing performer, with fantastic SQ and extreme headroom, I'm sure the H tuned a touch lower would be just as impressive and roll off for movies with just enough LF response to make it scary

To everyone, the build quality of the boxes was truly top notch, with double walls all the way around....

John, quick question will there be grills planned out for that box ?

Now you tell me...I placed my order yesterday

Simon recommended the AV15X with dual 18" PRs (1600 grams each), I have 11 cuft boxes already so I can use one of them and I would ahve a 15Hz tuned sub.

Is there a discount for just two PRs/AV15x?

You also posted the AV15H is better for HT...hmmm. Should I re-order everything.

In the end performance is key but $$$ do always matter to me. Yes, I tend to buy too many things

and I should have just spend all the $$$ a long time ago on LMS drivers but where is the fun in that

This thread was specifically about the Mal-x vs AV15 w/ 2 PRs....both options are under $500.

I have already decided to go with the AV15 choice for now. I can not help being a loyal AE speaker fanboy

Note: my current twin TC2000 15" drivers tuned to 15Hz are no slouches down low so I do not expect any thing better although I suspect the PRs are superior to having 8" round ports. Im more interested in the 40Hz to 70Hz performance, that is where the TC2Ks fall a little short (especially in measurements).

Your GTG posts got me excited about the AV15s actually so I have been waiting to pull the trigger since I read all those posts.

penngray, you should be good with the AV15X, it performs better in the mid-bass, 1-2db's, that you're looking at. I had the same concern as you and went with the AV15X and two PR18-2100. It gives up about 1-2db's or so below 20hz to the AV15H. Since you're going with bigger boxes the AV15X is better suited for that, the AV15H is better for smaller boxes.

Also, I would put two PR in one box to better balance each other (less vibration), putting one PR might cause the box to shake too much. Finally, you might want to check out my thread at AE, under AV15X, AV15H or TD12S? I think it will answer some of your questions regarding both sub models.
