I think it's fair to say that things are always more complicated in room than in theory.

Just 20Hz and below. Above 20Hz, the wavelengths will get progressively shorter.

But it wouldn't necessarily be worth a trade to go from two Rythmiks to one cap depending on circumstances.

Figure with two Rythmiks non co-located like you are using them - there is only about a 3dB advantage over having a single Rythmik. (a six dB advantage would require you had the pair double stacked (or otherwise co-located))

You can overlay the two subs max output and frequency response, one over the other at data-bass.com now days. Just select the sub from the drop down you want to compare.

http://www.data-bass.com/data?page=s...d=117&mset=129

When you do so you see the JTR has 3dB-6dB advantage over the FV15HP everywhere except 30-40hzish. BUT with a pair of subs you get some nice frequency smoothing in room, so your bass experience will be more consistent seat to seat over that of a single subwoofer.

The 20hz difference between the two subs is pretty impactful. The JTR has about a 6dB advantage in output at 20hz over the Rhythmic. 6dB is right at twice as loud. So putting this all together that means at 20hz, the JTR would be about the same volume as your two Rhythmic stacked on top of each other. 20hz is a pretty critical area for movie use --- so the advantage is there, but it will really depend on room, volume preferences, and bass smoothing needs as to whether you find the swap worthwhile.

Thanks for the responses! So, if I'm only concerned about the bass response in the main listening position, I should definitely go with a single Cap 1400. Is that correct?

I don't believe you'll gain much by switching from a pair of FV15HPs to a single Cap 1400; however, if you only have space for a single, or if you're looking to upgrade to a pair of Caps, it could be worthwhile.

@Archaea .. I'm sure a lot of members and others including some ID companies here. Is probably waiting for you to put up another gtg blind test shootout. Especially with all the new sub designs from different ID companies. Sound quality, capabilities, and a all out spl till what level each sub start spittn. A gtg would put a lot of questions to rest..

No way I'd give up a pair of FV15HP's for a single Cap. Dual Caps for sure! Are your FV's running out of steam?

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

My only current issue with the FV15HPs stems from the drop off above 70Hz, which is evident in the measurements both from data-bass and within my own room (my own room actually causes them to drop closer to 60Hz, and much faster than the data-bass measurements). My cross-overs are set at 80-90Hz (depending on Audyssey minimums for each speaker), so I feel like I have a gap in my response that could potentially be solved by the Cap 1400 (or so it seems by looking at the measurements). Thoughts?

Are you using line in or LFE? I believe line in only extends to 90hz and LFE extends to 200hz.

Sorry for the delayed response, I was using the line in for the longest time, but have since switched to LFE as of a few months ago. Weird thing is that my measured response is no different

@tvuong

Any ideas here on what chipless could do to rectify his issue?

Are the sub crossovers set to max? What's the Avr LFE set to? 120hz? If you turn off one sub and just measure one sub at the time, does it still roll off that early? Do you use REW to measure? What REW channel was used to measure subs? I would call Brian.

Don't know how many of you from the KC metro area still frequent this thread, but wanted to let you know that the Home Acoustics Alliance is planning to hold a class in KC right after July 4th. This is a rare event. I don't think they have ever come to Kansas City before to teach a class. There are many levels to choose from. Classes are for both professionals and enthusiasts. Want to know how to actually calibrate for multiple subwoofers the correct way? How to calibrate Atmos, DTS:X and Auro? How to calibrate using different types of DSP's and work with multiplexers and how to use excellent acoustic equipment? Want to know how to treat your room and lay out the room properly? Then this is the series of classes that teach you to do this correctly. I'll post details as soon as I have them, but I do know seats are limited.

Thanks Shawn,

FWIW, the Des Moines and Omaha avsforum gangs live within about 3 hours and sometimes come to our KC events as well. Both also have similar area meet threads.

Let us know details.

FWIW ---

I'm hosting a movie/game night at my house on Friday August 19 at 7PM. All forum friends are invited. It's posted in the KC thread.

Gamers/AVS forum friends welcome. @stitch1 is signed up to attend. @Luke Kamp you need to come. I invited @Scott Simonian and @jedimastergrant , but I don't think any of the other KC crowd is that much into PC gaming? (and Scott would have a LONG way to travel). @sigma722 is only a console gamer I think?

Anyway - this chock full weekend of movie and gaming fun is compliments of my wife being out town for the weekend with the 3 kids visiting her family in PA. You know what they say?!?! When the cat is away...........

That's quite an event....unfortunately not my cup of tea. I know if I got into gaming..I'd be addicted ....and eventually single.
