subwoofer suggestions for two channel audio

Is that Nak one of the ones using Nelson Pass' Stasis technology. The Nak amps I've heard with Stasis technology sound superb. Everyone (sic) knows that DQ-10's are soundstage champs.
 
Yes JoeE, It is so fast and dynamic on complex stuff I just can't believe it. All instruments or Artists are almost point source and solid. On Stevie Nixes Another kind of love you can tell that she is standing on the left of center stage. On a big coral piece all the sections are seperate not blurred together like other equipment that I have used. The 60 wpc drives the DQ 10's with no effort or strain at any level. The phono is DEAD quiet at FULL volume. most of my listening takes place at 12 to 1:00 on the volume with the 24 db of gain on the MC section. I know many laugh and say who is this guy
trying to fool. The Koetsu will reproduce human voice to die for, I did not know how good it was until the Nak. I had used a Dynavector DV6a SUT and the real music was getting stuck in there.

Sorry, no experience with that sub but it's a Yamaha and I've had good luck with their speakers.
An inexpensive way to start out with sub woofers is to surf the CL ads for mobile audio subwoofers being sold as someone switches cars or grows out of their "boom-era". They usually go for low prices and quality is all over the map. If you research which brands are good, I'd bet you can score a good pair at dirt price. I'd also suggest to skip the plate amps and buy a pro-audio amp. You will get more for your buck. Distributed bass is > than one subwoofer, get at least two.

stuck in the same quandary as OP myself. Have not used a subwoofer for 2 channel before. My entire 2 channel system is vintage. Didn't want to go expensive on first sub in case it really doesn't work out. Very similar to OP. I am currently thinking about one Dayton SUB-1200 ($148 for 1) or two Dayton SUB-10000 ($238 for two) or two Dayton SUB-800 ($178 for two). Room is 31'x12'x 9' ceiling (avg). Any suggestions on one big or two small or two smaller? I have four pair of primary speakers in the room (only use 1 pair at a time) they are: Focal 826v, ESS AMT-1 tower, KEF 104/2 and ADS L-730. Any thoughts?

You've got some good speakers there, all of them being fast and accurate. I'd suggest you get at least two subs and smaller than 15". If you get four 10" woofers and mount them in " H-cabinets", you'll get some good integration. One of the better systems I heard used Peerless woofers.
 
Question regarding Rythmik subwoofers: Does anyone know the main reason that the Rythmic L12 is only $569 while the F12 is $874?. They seems to both be servo subs, the L12 is 300 watt vs 400 watt for F12. F12 goes to 14 Hz while L12 goes to 18 Hz. Are those differences worth $305 in a 2 channel only system or am I missing something?

Edit: Aluminum vs paper cone.

westend, thanks for the multiple woofer suggestion. Pardon my ignorance but what is an "H cabinet". Thanks
Click to expand...

It is an enclosure housing two woofers in an open baffle, dipole alignment. One woofer faces you in a part of the "H" and the other woofer faces away in the other part of the "H". It is a four sided rectangular box with a baffle in the center.

Just remember two channels, two subs. And remember the cone displacement of the subwoofer should be 4 times the stereo speaker woofer.

Just a few of the differences I noticed at a quick glance, the F12 is 50% heavier, has a class AB amplifier vs a class D in the L12, the cabinet is considerably larger so more expensive to build and brace, etc, and there are other connection options and electronic features. The F12 also comes in a signature version with the grand piano gloss black exterior if looking for that, and I definitely would be.
 
There are lots of configurations for open baffle subs. This article is a great resource to understand those DIY "off the beaten path" options.

Other than the "I" or flat baffle I've yet to see any of these designs from a commercial speaker company and it has nothing to do with their sonics which put box subs to shame.

Nelson Pass uses his "SLOB" ( slot loaded open baffles ) subs with his Lowther OB's.

MJ King who pioneered the H-frame design uses a double version with his OB Lowthers.

Eric Alexander of Tekton sold these open baffle hybrid subs to be placed underneath his OB 4.5 speakers. The reviews were excellent but I no longer see them on his website.

Thanks for all the suggestions. Took the leap of faith and bought the Rythmik F12. Been using it for a week or so. I was expecting more pronounced low end. It is rather subtle which, I guess, is how it is supposed to be.

If set up correctly it's common to think the sub is not on until shutting it off, it really shouldn't call attention to itself. It's the lesser subs that need to cover up their inadequacies with over boosted bloated bass that soon becomes tiring leaving so many with the impression subs are for HT only.

That said, it can often take weeks of tweaking to get the sub where you want it sonically.

I replaced the rubber feet on the Rythmik F12 with casters. Now I can roll it into the living room (where the Altec 19s are) when wifey is away (like now). I am ABing the subwoofer on and off using channel 2 and I can really tell the difference. Listening to Blues on KPLU and it really makes a difference waaaayyyy dooowwwwn loooowww!

As it should be, I'm glad the Rythmik is working out. As I said earlier, I really like my two Daytons a lot, but even with two the servo sub wins in the musicality department. And if the pockets deep enough, nothing wrong with two or more of the Rythmik subs lol.

Kingshead thanks for coaching me on the subwoofer hunt. I can see what you were talking about now that I am breaking them (and me in) on the right music. I am not sure about the pockets but I am pretty certain about the WAF on a second sub in the living room even with casters!
