Looking for sub..these are what I narrowed down to. The klipsch is 3k with the amp, SVS is 1600 and Rythmik is 1274.

I can't demo any of these..any preferences ?

20 x 14 room. Using Klipsch 650 THX mains.

Why not consider Funk Audio if you're considering up to 3k? http://www.funkaudio.ca/Home.html

Based on your above stated budget choices, I'd expand my choices out to include the likes of three, PSA, XS15's. And if you just have to go with a single subwoofer solution, I would consider the likes of a PSA, XV30, XV30f or a XS30. I would also consider a Rythmik, F-25.

The reasons are, output and depth of extension.

There is a Funk Audio sub for sale in the AVS classifieds right now. Funk is rather exclusive, you don't see lots of guys owning them, build some fine cabs. The PB 13 Ultra has some serious output and some of the lowest test distortion figures recorded. In the USA the PB ultra is $1999. I owned a Rythmik FV-15HP, for the price its very hard to beat. Substantial accurate output. See the test data performed by Josh Ricci on the Ultra and the FV15HP.... link below. Do a little research.
Many people will give you opinions on subs but better to trust valid test data, and those reviewers who have listened and tested many subs. Opinions are like a$$holes, everybody has one.

Yea the PC ultra not the PB for 1600..my bad.

The FV15HP does look to be the better deal based on the test data above

I own a Rythmik f15hp. It is the best sounding subwoofer I have ever owned. I have previously owned SVS, HSU and Velodyne. In my opinion for the money you cannot beat the Rythmiks for sound quality.

my humble opinion cool.gif

What few will say or try to emphasize, once a fine testing subwoofer, without first being properly integrated into a room's acoustics, reproduces sound waves, all bets are off. There is no "Mother Nature." There is only nature and in nature, room acoustics will ruin the output of poorly integrated subwoofers.

(yes, the FV15HP is a well respected subwoofer)

If I had to choose among the three you listed I'd go dual FV15HPs myself but if I were Canadian Funk would be my first choice. For up to 3k you might be able to get a Seaton Submersive HP, a very nice sub....

Perhaps consider the Funk 18.0 summer sale model -- $2,550.00, or so, shipped. Otherwise, dual Rythmiks seem hard to beat.

I don't know anything about funk audio. Does the Funk 18.0 outperform the Rythmik or say a Seaton Submesive HP?

I hope so, having just purchased one! Its component set would suggest as much.

i would say it does not outperform the Rythmik, but not really a fair fight considering the size difference. aimed at different customers

I know there isn't any measurements on the SubM HP but I still think it would out perform a Funk 18.0.

My Gear:

JTR Noesis 228HT (LCR)
Axiom Audio QS8 surrounds
Sherbourn PA 7-350
Pioneer VSX-21TXH
JVC RS45

SENSITIVITY:130dB @ 30Hz, 122dB @ 20Hz, 112dB @ 15Hz 1/8 space, 1m (2 enclosures side-by-side per THX Ultra2)

As per the specs on Klipsch website, all those SPL numbers are with two enclosures co-located and @ 1m.

Going by the measurement technique used by Josh Ricci (2m ground plane), let's take SPL @ 20Hz.
If measured from 2m, it is 116dB. Make it one sub and it is 110dB. Also, subtract the room gain (1/8 space = corner placement) i.e. roughly 4-6dB. Taking the average figure of 5dB. So, with the acutal 2m ground plane measurement, it dwindles down to a paltry 105dB @ 20Hz.

SVS PB-13 Ultra and Rythmik FV15HP will easily best KW120 THX. Too bad on Klipsch's part to charge $3K for an average sub.

I think your math is a little bit off.
Subtract 12 dB for going from 1/8 space to 1/2 space, and that leaves you with 98 dB / 20 Hz / 2m.

It was 2m compared to 1m. That's 6dB drop for every doubling of distance.

I get that, I'm just saying going from 1/8 space to 1/2 space should drop another 12 dB. I of course could be wrong biggrin.gif
122 dB / 20 hz / 1m / 1/8 space / 2 subs
116 dB / 20 hz / 1m / 1/8 space / 1 sub
110 dB / 20 hz / 2m / 1/8 space / 1 sub
98 dB / 20 hz / 2m / 1/2 space / 1 sub

thanks for that guys. Klipsch cost to performance ratio does seem to be a little high.

Still dialing it in a bit -- will go through the DSP with Nathan Funk some time upcoming. That said, so far, so great. I bought it to fill in the deepest frequencies (within reason) in a fairly sizable room otherwise handled by two JBL 1400s and a JL 112. I have since lifted the LFE duties from the 1400s, which are incredible with music and provide great slam from 30 Hz and above, so I just run them as part of the front tower system with the corresponding JBL PT800s and cross to the FA and JL at 40 Hz.

Used this way, and with lots of SPL orchestrations between the FA and JL, I seem to be on to something. First impressions, borne of a few days of experiments, are that this is a terrific piece, and a most worthy alternative to the best from Paradigm, JL, and Velodyne, and presumably other ID brands. The reach down deep makes it further compelling versus otherwise terrific subs like those offered by SVS. I otherwise considered the JL 112 (to match the pair), the JL 113, the Paradigm Sub 25 (and similar models, though i was less interested in the Sub 1 and Sub 2), and SVS 13-inch models. I have not heard the Seaton or JTRs, but their size and appearance would not have worked in our space so well.

Further to the FA, the "work of art" aesthetics, intriguing ID genesis (had not owned such before, as I have JL, JBL Performance and Synthesis, Revel, and Pioneer EX otherwise), and that low end sold me. I love the JL 112, by the way, and would not hesitate to recommend any of the Fathom or Gotham models. Nevertheless, I was not sure if even two of the 112s aside of the 1400s would have had me hitting the built in limiters (I have done that on my single unit several times before dialing it in more effectively).

The FA seems limitless in comparison and even with the 1400s consigned to front tower, crossed-over duty, would overwhelm my large (4000-plus cubic foot) room with the JL if I did not keep it on a leash.

My new favorite pastime is watching the driver/cone excursions on the two subs. I assume this will pass so I can watch movies again. I do not have a grill cover for the FA, yet (and usually keep the cover off the JL). The driver/cone is a wonderful thing to behold on both, particularly on the Funk.

I would do the same thing all over again (as to the FA) and would have purchased a new one in the first place, but was impatient and saw Banisher's highlight reel, piano black model for sale, so I jumped. The sale model FAs are a great deal, as are the list prices for the full-on deluxe FA 18 models. SVS and Rythmik subs both are a great deal, but the lowest-end extension, overall frequency curve, and work-of-art profile of this sub give me the truest, five-star smile.
