I'm not using any eq on my AVR. So, the only eq is for sub only via MiniDSP 2x4 unbalanced.

Sub only measure in REW didn't change between 12dB and 24dB slopes in Line In. Same for CC+sub.

Right now I'm listening with crossover set to 100Hz in AVR to see if it sounds better despite no difference in measurements...

Hello Synaptech,

Hope you are well.

I thought you purchased two L12s? Did you send those back for two L22s?

Your room is slightly larger than mine with two large openings, I have one opening, and a dead end hallway that I can close all the doors in.

If you are rattling your windows with 2 L12s then I should be good to go. If 2 L22s I will have to see if I need another one.

Later,

Tony

You're right! Sorry! I was considering the L22.... went with 2xL12. They're half the L22

My room is roughly 15x20x9 with a large opening into the foyer/staircase (10x10x9) and another large opening to the dining room (15x15x9).

L22s would likely cause me structural issues

Hi Enrico

I have an F15 and was wondering if I add another sub ( mostly an f15hp or e15hp) as you no longer sell f15, will I be fine with an avr with audessey xt 32 or should I be looking at disposing the f15 and start afresh with two new subs?

Thanks

You can for sure add a F15HP or an E15HP to match your F15 but also know that we can build a F15 with A370PEQ3 amp to match your actual F15. Just send me an email to give you the price... About the AVR with Audyssey XT32 + SubEQ HT, it's always good to have a receiver with SubEQ HT or any kind of DSP with independent subwoofer outs when you run dual subwoofers.

You might be able to find a review for a F15, F15HP, or E15 and assume greater output. I suspect that Rythmik's sealed 15" models are quite similar.

I'm certainly not a professional reviewer, but I'm happy to share my opinions or answer questions.

Tell e about your F25s. Do you change anything from music to movies?

Does Rythmik Audio still offer the home trial where you can test them out for a month and if they don't work out you can return them for a full refund? I've narrowed my search to the svs pb-1000 and the Rythmik lv12r and after reading some threads the general consensus seems to be to go with the Rythmik.

The thing is that my bedroom is 12x12x8 and the LV12R maybe too much sub for my room when watching movies. Id like to rule out if that's the case or not.

I can answer this question, yes! The only minor exception is the F25, in which case you have to pay return shipping.

Just get the better sub. You're not going to be in a 12x12 room forever. I hope!

All the more reason to get the cleaner sub, in my opinion. Room modes are going to be a b****, though.

This is what mine looks like with Line In, 120Hz crossover on sub, and 24dB slope (12dB slope looks the same too). AVR crossover is 80Hz.

^ And by the way, I experimented with sub placement everywhere I could and this is actually as good as it gets (pre EQ sub response).

I have the exact same room dimensions and the LV12R is not too much sub for me. And I only listen at moderate volumes.

Return shipping is not covered as far as I know, but you do have 45 days.

Yes, cleaner bass is better than muddy or boomy bass. Room modes are terrible with 12 x 12 x 8 feet, which is why the best I can do before EQ looks like it does in the image above.

Too much sub is an easy fix. Just turn it down.

Not enough sub is expensive to reconcile though.

Yes they do.

Brian makes terrific products but (as I have told him) does a poor job selling and marketing them, and finding important info on the web page takes way too long, if you can find it at all. (Also, I proofread technical documents all day long, so his typos bug the heck out of me. )

He has a 45 day audition period. (Although many of the sub pages say "30 day satisfaction guarantee")
  • All returns need a RMA number. Please contact us before you return the product.
  • Complete subwoofers can be returned within 45 days after you receive the unit. In case of return, customers only pay for return shipping.
For me returning the F25 was going to cost me almost $500 bucks.

Yes, which is why I made the rather huge jump from a $150 Dayton sub to the LV12R. I didn't want to have to upgrade again anytime in the near future.


(Next upgrade in store will be an Audyssey XT32/Sub EQ HT AVR.)

He has a 45 day audition period. (Although many of the sub pages say "30 day satisfaction guarantee")
  • All returns need a RMA number. Please contact us before you return the product.
  • Complete subwoofers can be returned within 45 days after you receive the unit. In case of return, customers only pay for return shipping.
This statement is not 100% accurate, like I said the F25 customer has to pay return shipping, and residential pickup, and liftgate service. For me returning the F25 was going to cost me almost $500 bucks.

Are you sure return shipping is covered on the LV12R? I wasn't aware of anything like that.

Return shipping is paid by the customer, as quoted from the Rythmik website - "In case of return, customers only pay for return shipping."

They are clean and articulate. They make it sound like your mains got great bass, rather than drawing attention to themselves. They aren't power monsters, but the pricing is good enough that you buy more to make up for it, and I'd rather have more subs for room modes and better seat to seat consistency. I have a 6000 cu. ft. room, so I have demanding power needs.

I was able to compare them to FV15HPs, and I much preferred the F25s for music. I also preferred the F25s for movies, but by a smaller margin. In both cases, the F25s had more detail in the bottom couple octaves and had less localization, although the FV15HPs could produce more output per sub.

For the difference in detail in movies, one particularly clear example was in Incredibles on the island, when the killer robot was rolling around chasing Mr. Incredible, bouncing around the ground and smashing through trees. With FV15HPs, it sounded like Rumble! BOOOM! BOOOOM! And impressive sound effect. With the F25s, it was like you were really standing there, able to feel every subtle interaction between the robot and the ground in detail, not a sound effect.

With music, the F25 sounded more like real bass drums, and less like subs.

These differences were mainly below 40hz. Above that, they sounded extremely similar. Above the bottom octaves, the only way I'd be able to tell in a blind test was that the FV15HPs were easier to localize when using a crossover over 80hz. Mine are currently crossed at 100hz, so this was an issue for me. Compared to my previous Velodyne sub, I am impressed with the Rythmik subs' abilities to handle higher frequencies.

To really get drums sounding lifelike, I found that combining with high efficiency mains (running JTRs) and fine tuning frequency and impulse response with Dirac also contribute a lot. After all, drums aren't just in the subwoofer frequencies, and typical tweeters simply can't reproduce lifelike transients.

Once I used Dirac to fine tune the response, I was able to find a single setting that worked very well for most movies and music. I struggled with that when I was trying to dial in the response by just tuning the crossover and sub gain.

Also, I was much happier with the results when I corner loaded (4 corners) and used EQ, instead of going with sub placement that produced the flattest natural response (front and back center wall). As long as there are no nulls, Dirac and XT32 each did a fine job managing peaks (although I prefer Dirac, especially for full-range EQ). With center wall placement, I found that I was sacrificing too much output to produce truly satisfying bass in my room.
