There have been quite a few posts about Subs lately so though I would post some pics of my custom Salk Rythmik 15" sub I recently received. I have a second one on order, but there was a delay on some parts so I just have the one for now.
I apologize for the poor quality of the pics, I am not much of a photographer.
I was evaluating all of the various ID subs HSU, Rythmik, Epik, SVS etc etc. My primary interest is clean bass for music, although I use my system for HT as well. Extremely high volume isn't a priority for me so I focused mainly on sealed designs.
I decided to call Jim since I have been so pleased with my STs and he recommended the Rythmik in a Custom Cabinet. I decided to order from Salk and am really pleased with the result. The Cabinet is stunning (straight mahogany veneer to match my STs) so even though they are quite large, they don't seem out of place in my Living room. The sound quality is fantastic and very musical.
I am using a Denon 4311 with Audyssey XT32 for the sub EQ.

Wow, gorgeous cabinet. Did Jim only do the cabinet for you, or did he assemble the whole sub for you?

Thank you!
Jim put together the whole sub for me, so it arrived ready to plug in and go. I think he uses a Rythmik driver/amp kit, and in one of Jim's e-mails he mentioned he modeled the cabinet to optimize it for the 15" Rythmik driver. It is a bit larger than the standard Rythmik design.
I also wanted a down-firing design to avoid damage from my big dog and two cats who love to scratch on speaker grills, so he modified it to be down-firing rather than have the driver in front.

Nice. I bet that will be amazing when both are set up. I love the Rythmik subs with the GR Research cones. Enjoy :thumb:

beautiful.

Wow that is nice! Congrats on that beautiful subwoofer. Dual custom D15SE's should sound amazing! Do you plan to apply any PEQ using something other than what's built into the sub amp(s)?

I am hoping to get by with the built in PEQ. I have identified some really good spots that worked with my old subwoofer, so I am hoping the new ones measure out similarly. If not I can use my Denon 4311 Audyssey XT32 on top of that and use the "Bypass L/R". I am not a fan of what Audessey does to my mid-high frequencies, its just too bright for my tastes with the ST RAALS. It measures pretty flat but seems harsh to my ears.
I don't plan to spend much time on it until the 2nd Sub arrives.

Actually our woofers aren't clones. Brian and I worked together to design our woofers. The goal was a lighter weight paper based version that will be cleaner, faster, and offer better resolution levels. Basically our woofers are the audiophile version while the heavier metal cone version is more suited for home theater applications where they will be driven hard or where quality is less of a concern to overall SPL levels.
-
Hey Danny, which is the heavier HT based woofer and which are the paper ones? I thought all the Rythmik ones were paper, but now I'm not sure of the differences.

Brians observations posted on his site: Driver comparison
The GR drivers use a lower mass paper cone, which has a slightly better transient response. The result is slightly better dynamics. At higher output, due to less cone stiffness, the sound may become softer due to the pressure placed on the cone.
The GR drivers also have a more extended response, allowing a higher crossover point if desired.

Cool - sounds like a plan. I agree that Audyssey does some funky stuff above the Schroeder Frequency, and that's why I never use it. My subs are DIY, and the amps I chose don't have built-in PEQ. I got a used Behringer 1124p for $50 that works extremely well; I couldn't be happier...well, unless my subs were 18" LMS5400's rather than TC2000 15's. HA!

Sounds like a nice setup! Ideally I would like to find an EQ solution that would allow me to tweak the mains up to the Schroeder Frequency as well as the Subs. Audessey really tightens things up in the 80Hz-200Hz region in my room, but the compromise of the harsh high end isn't worth it.

Am very envious. Still trying to figure out how to sneak in
a 20"x20" sub without the wife noticing. Fat chance !

Ah, so it has. Probably in a futile attempt to enforce sensible behavior. Must have been a while ago now.

Topic: "Delete Own Post" now disabled
http://www.audiocircle.com/index.php?topic=101466.0
I don't think it had much effect on behavior, as posts are now being edited and replaced with either "Deleted" or ".", whereas previously being able to delete a post visually cleaned up the topic.
Ocassionaly I removed a post because I later decided my comment was better left unsaid, but more often it was because the comment was either not relevant, had previously been said, or was posted in the wrong topic.

Oh right. I don't remember what caused that. I'm pretty fed up with the whole thing, frankly. Might as well turn all of it off.
Apologies to Salk folks for the intrusion.

DOH - sorry for taking this thread off-topic; that was not my intent.
I forgot to ask, do these Rythmik subs utilize the new HP amp @ 600 watts as opposed to 370?

Yes, it is the H600-PEQ3 and I assume the DS1510 Driver, although the DS1505 looks identical on the exterior.

Wow - even better! Jeez...what a setup you have. :D

Yes I am really pleased with it.
Jim is just incredible to work with. I just explained my requirements, preferences, room size etc. and trusted his judgement on the details. I only specified 15", but he still went with top of the line components across the board.
-
How much was it for the two subs? I am considering the same set-up you have and I am wondering how big of a change there is between the ST's vs. ST's with dual subs.
Thanks,
Kevin

Any improvement would largely depend on the content you enjoy, size of your room and volumes you prefer so it is difficult to estimate "how big" the change may be without some more details.
Unfortunately I can't fully comment as I am still waiting on the 2nd Sub. I think Jim has the cabinet completed and is just waiting on parts from Rythmik to finish it up. Even the single sub for me is a huge improvement in the clarity and impact of the bass.
I would recommend calling Jim for pricing as I am not sure if its kosher to post here, but will say that at least to me the Salk subs are extremely good values and much less than I would have expected.
There are many folks here with dual (or quad?) subwoofer systems who I am sure would be happy to chime in if you post additional details or start a new thread specific to your requirements.

Well my 2nd Sub has arrived!
All I can say is WOW!
I was expecting some improvement, maybe 25% subjectively, but I would call it close to 200% in reality. The 2nd sub really evens out the bass and energizes the entire room (6000+cuft due to open floor plan and cathedral ceilings). I was really happy with the single sub, but adding the 2nd is an entirely different deal - just amazing.
Thanks again to Jim and the crew at Salk for a fantastic job! :notworthy: :bowdown: I couldn't be happier with the result.

Congrats again! Dual subs is certainly a necessity in that size room IMO, and I am glad they're working out for you.

Dual subs is certainly a necessity
I prefer 4. :D

Danny---Is there a cabinet maker offering a box for a double 12" GR driver/Rythmik 370 amp combo? And do you offer drawings for such a cabinet (3-4 cu.ft.)---Eric.

I had an 8 ohm woofer designed just for using a pair of woofers with one amp. I sold out of them though, and Brian decided that instead of paralleling two woofers onto one amp, he wanted to go to a two channel amp. I think his new two channel amps are still under development.
However, as I was going through my 4 ohm woofers, a few weeks ago, I found one last pair of the 8 ohm woofers. So if anyone wants the last pair to build out a dual woofer sub then now is your chance.
I would replicate the single box or single sand box design as a double with a common dividing wall between them. So they then have a common top/bottom and front/back panel.
And you are posting in the circle of one of the best cabinet makers around. I am sure that Jim can take care of you on the cabinet.
-
Ooh, that would be great Danny. But I'm going to have stereo subs, so I would need four of the 8 ohm drivers, two per side. You have the two only, eh? Thanks---Eric.

Yep, only two left.
You might want to wait for Brian's new two channel servo amps. Then each SW-12-04 has it's own amp channel.
-
Ah, so I see.....I would have two boxes per side, each containing a 4 ohm 12" driver, the two powered by the upcoming dual-channel Rythmik amp. For stereo, I would need one of these set-ups on each side. Or to get two 12"ers per side right now, I could just get four F12's, and stack them two high on each side. I was under the impression that I could presently get two cabinets, each containing a pair of 8 ohm 12" GR drivers powered by a 370W Rythmik amp, a dual F12 in otherwords. I didn't know that the Rythmik amp's servo-system would not work with two drivers. Never mind! And thanks for setting me straight.

No, the Rythmik amps work fine with multiple woofers. With our SW-12-16FR woofers (16 ohm woofers used in free air, open baffle or infinite baffle applications) we can put as many as three woofers on each amp. You just have to keep the impedance to 4 ohms or more.
So with our SW-12-08 (8 ohm woofer) you can run a pair per amp. But I only have two left.
Using our SW-12-04 (4 ohm woofer) you can only use one woofer per amp. But Brian's new amps that will be available later this year are suppose to be modular. So with one set of servo controls You can use two amp channels or three amp channels, etc. You just add another amplifier module. So each 4 ohm woofer has its own amp.
If you are looking to run four woofers in your room then from a performance stand point I have to mention that there are great advantages from putting a pair of woofers in the front of the room and a pair of woofers in the back of the room. You then run the woofers in the back of the room out of phase from the woofers in the front of the room. This can take away a lot of room loading and balance out the bass response very well. So you get very high quality bass without the boom of the room being mixed in.
And Jim can build you the cabinets for all of them. :thumb:

Okay Danny, NOW I got it! I at least now know I'm getting my F12's with your GR driver and Brian's 370W amp. I just need to wait for the XLR2 version to get into production (I want to send a balanced signal from my pre-amp to the subs). Thanks for all of your help---Eric.
