Anyone have any ideas when/if they will release a new sub?? I hate getting something, then something newer comes along the next few weeks or so... Ha!

(just a hint, Shhhh we won't tell anyone) ;-)

Thx!!

Hi folks, I'm looking around for new sub(s). I'm wide open to all options, in my mind I think sealed would be better (for music), but I know that may not be true.

I currently have dual SVS CS-Ultras circa 2001/2002. My theater is in my avatar photo, and it is approximately 18x19x9. Sound treated walls 2 layers of 5/8" sheetrock, concrete floor covered with carpet.

I'm looking at the largest subs in the Rythmik line, and I plan to get a pair. I'll use it for music and HT, but I'm a more critical music listener.

I look forward to you folks sharing with me your thought process in selecting a Rhytmik sub, and how you like it or not now that you own it/them.

Thanks!!

The FV15HP is extremely popular and a potent vented sub, especially for its size.

The F25 might be another option you may want to take in serious consideration which is a sealed dual 15 woofers sub.

Either in pairs should be great but the FV15HP will have a bit more output at tuning while the F25 should dig deeper.

Myself, I have been quite pleased with my sealed DIY 15, with 370w amp, for last fours years+ but will be augmenting it with a pair of DIY 18s this coming year.

Best regards,
KvE

If you want the biggest I would recommend the F25s, but I really doubt you need that much output considering your room isn't huge. Take a look at 2xF15HP.

Thx Soul! From what I've read dual F15HPs may get the job done for me.

Do you have a Rythmik sub???

Uh, you're in the Rythmik thread, 697 pages and nearly 21,000 posts mostly from people who have Rythmik. Read back a few pages and you'll see why many of us have purchased and enjoy Rythmik subwoofers in all their many flavors.

Personally I would go with a pair of the FV15HPs, or F25 and enjoy. Always better to have some extra headroom than encountering sometime down the road not having enough output.

Rythmik subs are awesome in performance, efficiency, and ease of use.

I have sealed F15 in 1300 cubic feet room and was purchased originally for music only duties, its sounded awesome on 2 channel mode, eventually a TV was added and it is devastating in that size of room. In your room, you could go with dual F15HP, this way you could position the sub for best output and response across the room.

Thank you for the info and suggestions!! I'm leaning towards duals... I'm thinking more even room coverage.

That's a great looking room you have and although dual F15HPs would probably serve you well, IMO, it deserves dual F25s.

Hope the terrible weather in your neck of the woods hasn't affected you too much, it looks like it's been pretty horrible.

Seriously doubt it...that's why I added the Winky smiley, you know, because my comment was partially in jest.

So relax, he can decide for himself.

So, I got the LV12R today. Noticed a quiet fan like noise emanating directly from the driver when the amp is set to on or auto and power light is green... this is after powering down my AVR and source devices and TV and with the room silent.

Is this normal?

If it matters the MiniDSP 2x4 unbalanced is in the signal path and on and sub gain is 2/3 to 3/4 of max. LFE input is used.

It should not be making any noise. Take out the Mindidsp out of the signal chain and listen to whether the issue persists.

Also try plugging in the sub in another power socket on another circuit.

Good luck.

Please do this. Disconnect any RCA cable from the sub and set the amp to ON (need to see green light). If you don't hear any noise this way, then the noise is from the source. Then I will suggest to trace back using the same method.

Thank you. You cannot imagine how much rain we have gotten or how bad things have been here. 5 of the largest area hospitals are without water from water line breaks, and roads and dams are a complete mess. I've closed my business for the last two days, because the main road to it has been closed. Three of our major Interstates were closed until Monday afternoon.

I've been fortunate as I live on a hill but the creek in my backyard turned into a raging river for two days.

Dual F25s is also what the Rythmik folks suggested for me as well as the upper end, cost no object. I'm tired of bottoming outmy subs on peaks in movies, and I listen to orchestral organ music often.

I intend to audition one sub and see how that goes, I do not intend to upgrade subs again for many years, I've had my current pair since 2002!

Take care and thanks for the concern about our flooding.

I don't "need" subwoofers.

What I've been told is that dual subs will give me, besides more headroom, the opportunity to even out the bass throughout my entire room. That is appealing to me.

Perhaps that is incorrect.

Take care!

I would reword that to say, "smooth the frequency response at and expand the sweet spot".

For me, the difference is dramatic. I should take a measurement of 1 sub vs 2.

With your subs in their current location, a compression sweep will let you know how much headroom is available. REW is your friend here. AVS member AustinJerry has written a step by step guide on using REW with a USB mic here: Simplified REW Setup and Use (USB Mic & HDMI Connection) Including Measurement Techniques and How To Interpret Graphs

With REW, you can check smoothness of the low frequency response, check for decay (ringing) and how well the bass management been implemented by the pre/pro/receiver. For the main speakers, the ETC graph is quite useful.

The current placement of the subs may not be optimal. A 'sub crawl' will help determine some optimal locations where to place the new Rythmik F25 sub(s).

I unplugged the rca cable from the sub's LFE input and turned amp to on (green light)... the sound is still there.

It wasn't there when amp was off (red light) and rca cable was connected to LFE input.

How much does a FVX15 weight?

Its shipping weight is 120 pounds, so I assume 110+ range but that seems pretty heavy for its size.

The FV15HP's shipping weight is 130 pounds. so it is comparable in weight. In case no one knows how much the FVX15 actually weights, does anyone know how much the FV15HP weights for comparison?

Thanks Steve. I've just learned about REW. I'm gonna order a mic and stand from Amazon, then fire up REW and see where I stand now, and learn how to use it before I get a new processor or new subs. That way I'll be ready to optimize both, more quickly.

That step by step guide looks much easier to use than their official HELP file. I just downloaded it. Thanks!

Cool. I plan to order one to audition and if that's enough bass, and distributed satisfactorily, stop there. If not I'll get number 2 headed my way! My budget for subs in $5K so let's see how this all works out.

Take care.

Thanks for reminding me the typo. FVX15 shipping weight is 115lbs.
