Man my room is only slightly larger than yours, and it's my belief that chasing the sub 15hz frequencies is a waste in rooms this large. I would go ported all day long and never look back (oh wait, I already did! ).

My advice, go for all the output you can get 20 hz and up, sit back and enjoy the ride

I thought you got the best response with all 4 XS15's stacked up front?

I agree with most of your post Randy but after having ported subs I would really say that I think 15hz and up and the important range. Even with me changing back to sealed subs I still think for me 15hz is the starting point of where I want serious output.

Since two XV30+2XV15 appear to be in the budget, I would get three XV30's. I really find it hard to believe that you won't be able to get a flat response with three subs and a miniDSP. Not that three XS30's does not sound sexy as hell, I just think 3 subs that each cranks out 110 dB at 20 Hz will pretty much rip your face off.

Oh man. Now that's a great problem to have!

Hmm… let me think. Do I want four awesome sealed subwoofers? Or do I want four awesome ported subwoofers? What's great about this dilemma is there is not a bad choice, just a good choice and maybe a little better choice.

But since you ask, personally I would take the four ported subs. Yes three XV30s would probably work but I would lean towards your original suggestion of two XV30s and two XV15s because with four subs you will gain even better bass response throughout the room.

Regarding depth of bass: Correct me if I'm wrong but wouldn't an armada of subs consisting of 2 XV15s and 2 XV30s have good output down to at least 16Hz?

Alan, I don't think there is a down side here but since you haven't been happy with the sealed subs you have I would just go right to the ported subs. I can tell you that dual XV15s are pretty wonderful, I can't even fathom how incredible dual XV15s coupled with their big brothers the XV30s would be.

The problem with having the XV15 in the mix is that it cannot match the output of the XV30. The reason I asked why not 3 XV30's? Two up front and one nearfield behind seat should have smooth FR along with very high output and tactile feeling.

I thought about 3 XV30s but think I would be better off with 4 subs for the most placement flexibility/room coverage.

Thanks for the confirmation that chasing ULF in a room this large is kind of a waste of time.

With all 4 XS15s up front I get the most extension, not the best response. Also, pretty bad seat-to-seat variance.

See my comments above concerning placement options....and the other option would be 4 XS30s, not 3.

Hmmm...do you guys think the XV15s would have trouble keeping up? This is a good point and something I would like to know for sure.

I would either opt for one or the other. Quad XV15se's or 2-3 XV30fse's. Although personally I would just go with a pair of the latter.

Display - LG 65EF9500
Receiver - Denon 4311CI
Speakers - Klipsch RF-82 II's, RC-62 II, RB-61 II's
Subs - Rythmik FV15HP's

Oh that is right Alan, I had it backwards. I do not think you will be satisfied with just duals of any sub. If my memory serves me correct(it is all coming together after a quick glance back through your thread), you need 4 subs. I do not think you will have issues running 2 XV15's in the back and 2 XV30's up front. The subs in the rear will probably need to be calibrated lower then the fronts, so I do not see any issues hitting limiters. Even if you had 4 XV15's I think you would have enough headroom because you were hitting the XS15 limits in the deep bass. the XV15 will net significantly more output in that region...I am betting a 8-10db difference factoring in the new drivers. The only reason why I said XV30's is the fact that you will be getting a massive performance increase which will keep the upgrade bug from biting for a bit.










Just think


4 XV30's will net 122db @ 20hz 2m rms


4 XS30's will net around 116-117db

2 XV30 & 2 XV15 will net around 120.5db

4 XV15's will net around 119db


Your 4 XS15's(older driver) net around 108-109db


As you can see either way you go will be a substantial increase in deep bass output.

I just love it when you pull out the hard numbers.

Wow, seems any way I go I'm gonna blow away the XS15s....can't really go wrong here.

Yeah, my thought as well...but if I can be perfectly satisfied with 4 XV15s (and, by the numbers above, it looks like I should) it will be considerably easier on the pocketbook and look better in my living room (higher WAF...not like she really cares though).

But...will I always wonder what 2 XV30s + 2 XV15s sounds like? Probably.

I think so if you listen loud close to or at reference level. The XV15 is 3db to 3.5db less output. Your subs system will sound as good as your weakest sub which is the xv15 in this case. I would opt for 3 XV30's if it was me.

3 XV30's and 4 XV15's will have very similar output capabilities(+1.5db to the 3 XV30's).

About your weakest link comment.. Yes that would apply if both the XV30 and XV15 were placed equal distance. However If the XV15's are only 6ft from the LP and the XV30's are 20ft from the LP, they both should hit the limits at the same time when calibrated correctly. You can not gain match the nearfield subs with the farfield subs or they will be out of balance. Remember you loose 6db of output every 1m of distance that is added between the LP and Sub. So the XV30's would need to be ran roughly 3db hotter to get a good balance imo.

I agree with basshead, I really don't think it would be too hard for you to pull off the combination you are thinking of. A little while ago I asked this very question, whether my dual XV15s would work well with an XV30 and IIRC Tom said they would work well.

In your case I would put my dual XV30s up front and run my dual XV15s nearfield (as basshead suggested) or at least close by to even out the response.

I guess the person who could give you a definitive answer would be Tom. Hopefully he will pop in here soon and give his input.

It's nice to know that the designer of the products we are discussing frequently comes by to spend time with us and help us with our little dilemmas.

And it costs less with 3XV30's. It is always a good idea to have the same subs anyway. If the 3 XV30's does not meet his expectation (highly doubt it), he can always add the fourth one. Going with the two XV15's will have him asking 'what if...' even with great result from the 4 XV30/15's combo.

Stop putting ideas in my head!!

Can you imagine....quad XV30s?? O...M...G!

Not sure if my house would still be standing after that assault...but, boy would it be fun while it lasted.


I'm currently waiting to hear back from Tom on the 2 XV15/2 XV30 vs. 3 XV30 debate. If he recommends the 3 XV30 combo, I just know I will eventually have to get the 4th...gotta keep it symmetrical, y'know.

I am not disagreeing with that...I was just commenting about the lesser sub hitting its limits. I personally would want 4 matching subs.

I think Tom's recommendation of quad XS30se is solid. Alan would basically gain 6-8db across the entire bandwidth instead of the majority gains being in the 16-30hz by going ported. Multiple sealed subs are a potent combination. 4 XS30's would get Alan reference capability down to 16hz even in that large room and possibly close into the 12hz. He would basically double his headroom across the entire bandwidth.

Alan, could you imagine being able to turn your subs up twice as loud?

Like I said it all depends where you want the majority of your gains.

XV30's would have enough 16-30hz headroom to allow a healthy house curve and get flat down to about 15hz. Do you need the extra 4db in the 16-30hz over the XS30's or would you rather have 3db more upper bass headroom with deeper extension going with the XS30's?

Decisions decisions....

I think @basshead81 already answered that adequately: yes, they'd keep up if they are placed closer.

This isn't right though. You loose 6 dB each time you *double* the distance. (When performing dB SPL computations starting from a speaker's sensitivity, it's most often rated at 1 m; or when converting CEA-2010 data at 1m to data at 2m; so you subtract 6 dB when at 2 m, but it's not because you added one meter, it's because the distance is doubled).

So if there is 6 dB difference in the max output of the XV15 vs XV30 (not sure what the real numbers are), then placing the XV30 twice as far as the XV15 would be sufficient to compensate for the difference. If you were in an anechoic parking lot, of course.

In a room, things are harder to predict, although a nearfield sub sure would not have to work as hard as a sub on the front stage. So if you go with 2xXV30 + 2xXV15, placing the XV15s nearfield should be sufficient to ensure they're not the limiting factor in the setup.

That is what I meant...forgive my typing from a Note 3. I agree in room things are tough to predict hence why I referenced to 2m rms. Point was the XV15 should be fine placed closer.

I can get flat to 8hz now with the XS15s...I should expect the same from the XS30s, no?? However, that is with all 4 subs up front, when I put 2 in back it kills my low end...not sure why it does, but it does. And, yes, I've tweaked delay and phase on the rear subs 'til the cows came home and the ULF just won't come back.

Alan, could you imagine being able to turn your subs up twice as loud?
This gave me goosebumps...and I think I peed myself a little.

Like I said it all depends where you want the majority of your gains.
What I really think I'm missing most is that "chest-slam" and "pressure in the ears" feeling that a lot of guys (with a lot of subs) talk about around these parts.

XV30's would have enough 16-30hz headroom to allow a healthy house curve and get flat down to about 15hz. Do you need the extra 4db in the 16-30hz over the XS30's or would you rather have 3db more upper bass headroom with deeper extension going with the XS30's?
Just when I think I have my mind made up on vented...you have to come along and make me re-think my decision...again.

Sure wish Tom would poke his head in here and give me a definitive answer. He must be really busy with the new speakers 'cause I only got one email from him today even though I've sent him like 4 or 5.

Maybe he's just sick of me.....

Go big or go home...another vote for 3 XV30's....ya know, income tax season is right around the corner, you can always add that 4th XV30 later on. Didn't you say this would even be a little cheaper?

But the XV30s are just such BEHEMOTHS! I'd rather have the less-tall XS30s (or XV15s) for the aesthetics in my living room, and big gains across the entire bandwidth is tempting.

Basshead seems to be the lone supporter of sealed over vented, but he makes some really good points.

I really think I would enjoy having the extra extension, I know I miss it from when I had the 4 XS15s up front and was digging down to 8hz. But now I drop off around 25hz, with the vented subs that would be more like 17-18hz...what to do, what to do....

Still saying, Alan you really can't make a bad decision no matter which way you decide to go. Nice predicament to be in.

Im in the sealed camp.

I had an XV15...and went with the XS30...now I have 2 of them

I am more for the superb extension and very good output as opposed to good extension and superb output

Alan, get the four XS30s and stack all four in the front of your room, two in each front L&R corners. I'm going with two more XS30s as soon as I get REW worked out, I AM GOING TO DO IT THIS TIME FOR SURE. Either way I would go for the quad XS30s, no matter where you put them. As long as PSA continues with the free return shipping promotion I have nothing to lose. Question: I've read Jerry's comments on the CSL and MiniDSP UMIK-1s and how critical is it in your opinion to have the FRCs at 0 degree (MiniDSP mic) and 0, 45 and 90 degree angles (CSL mic)? He mentioned that he used both cal files and it only appears critical in the higher FR. TIA and I know you'll make the right decision.
Cheers Jeff

PS: I might have a brand new MiniDSP UMIK-1 still in the box for sale at $75 shipped

I just thought of something.....

From your description it seems the issue is placement, not lack of output down low. If true, then wouldn't you have the same problem no matter which model you choose?

Dimensions are the same as the triax with 15 inch drivers. Specs should still be on their webpage.

Pictures have been posted on their Facebook page and also in the triax thread here:
