Please dont take this as a flame or jab at you, but you have about a 1/2 dozen threads between here and AH asking which sub to choose. You have HUGE room (5400cf) if I remember. IMO, you either need the VTF15 or the Empire (figuring that your budget is about 1k). IF you could up that to about 1300, then I would say the FV15HP would be your best bet. If you dont want to spend that much, THIS would be a crazy steal at $550 shipped if its in mint like the seller says. Then you could add a second LFM-1 EX as your funds would allow.

Best of luck to you!

I have been looking into both of these subs as well and would also like to know what people think about them both. From what I have read on reviews is that the Rythmik is slightly louder all around and one review said the HSU rolls off wuickly at 30hz. I kind of find that hard to believe about the HSU.

By all accounts (and threads on here and elsewhere), the VTF-15 is beast of a sub, borderlining on indestructible with several tuning options. Two members on here I know for certain (Ack-bk and Oztech) have them and rave about them. I was seriously considering one but in the end went with the Empire. To me, at the 1000 price point, its going to be very hard to beat the VTF-15 or the Empire. IF you can get two Outlaw LFM-1 EX's on sale then that would also be a heck of an option. By no means am I saying that the F15 is a bad sub in any way. Quite the contrary in fact as I have yet to read a bad review on it. However, with the OP's room size, I dont think it will have the output of the others I mentioned.

The supplied CD will more than confirm that it will play the 16Hz organ note and you have several tuning options with the fact room gain will add to these. It is a beast of a sub and at its price point IMO it has no equal.

What's making it hard for me to decide between the Rythmik F15 or the Hsu 15 H is that the F15 is only ported whereas the Hsu is ported and sealed by preference. Not sure what is better in my 5400 cf room.

I think Rythmik has nice subs if i were to get one it would be their FV15HP
but it is almost 500.00 more with shipping and tax.

I also have been debating between these two. The issue isn't going to be the sound as I am sure are both very nice. The main question I have is I see that the Rythmik has a heat sink and the HSU does not. At least according to the pics I have seen. Does the VFT 15H have a heat sink design?

Paradigm Signature S8v3, C5v3, S2v3, Studio 20v5, SIG-1.5Rv3(x4), and Rythmik FV15HP

The whole plate acts as a sink but I have yet to get mine past just warm.

For about the sasme money......Would you rather have 2 HSU VTF15's or a submersive? I have also been debating this. I know the submersive is a beast but have two different sub locations has its advantages as well.

Even though I own the 15H, I would probably say to get the Submersive based on what I have read from those that have heard them.

With the caveat that if you are sitting in the middle of the room or in a null, the dual 15H's would probably be better.

I have the 15H and I played around with the different settings and found that mine sounds best with 1 port open and 1 port closed. It's a different sound with each different configuration option.

Yes it does and it is the beauty of it. You can make it sound the way you like. One port, two ports or sealed. Then you got EQ1 and 2 plus the Q controls...hard to not find one mode that fits your needs.

The SubM. Unless I had a giant room (ala the OP) that would benefit from duals.

I think I will settle with the vtf 3 mk4 according to hsu it covers 6000 cf. On another note I can only place my sub near a window on a corner. Will it rattle the window?

Don't let the negatives get you down. Also most will want to cover your floor with subs. I don't need my dishes to rattle and move around with my sub. Not sure if your area is open like mine. Someone here on AVS did a review of the Rythmik F15 and the HSU 3.4 and the Rythmik won out on the sound. Again your choice and your money.

I don't think anyone can tell you if your window will rattle or not. That's not a generic question, but one that is relative only to your house's structure. I can tell you I have a 18inch/sub sitting next to my window and it doesn't rattle....are our houses built the same???? Neither one of us can say. Are there ppl that have windows rattle when their sub hits high output? Probably.

How could they possibly know?

Anyway, even if they did know - if they said "yes, it will rattle your window" - IMO the solution would be to cure the window rattle, not to forego the sub!

If your window rattles, then you need to fix it anyway (especially if you live in a place where it sometimes gets cold enough for you to need to heat your home)

Rythmik F15 is sealed. FV15 is ported and has a similar multi-tune option like the HSU. IMO ported would be the way to go in a large room if not going multiples.

asere,
Before you decide which sub to buy you should go to Data-Bass.com and compare the different subs. The thing you need to look at is the output curves of the different subs look at the shape of the curve and realize that the loudest is not always the best sounding. Look at the $5000 Velodyne and compare the other subs to it. I have a Rythmik DS1505 in a sealed box which is Rythmik’s DIY sub, basically a F15 in a little larger box. I have this in a 4800 cu ft very open room and it matches very well with my Klipsch speakers and has no problem keeping up. You need to be honest about how loud you listen to your system; mine will get loud enough to hurt my ears. I will listen to music around 75-85db's and movies 90-100db. All the Rythmik subs have the same curve; the difference is how loud they will play. Try to match the sub to the system you have or the system you are building. Just my 2C hope it helps
