Is the new HP F25 going to use the same cabinet as the standard F25?
and is there a CI Price yet?

Brian, I noticed a few days ago that the new link for the PEQ3 quickguide on the F12SE web page was broken... it still is.

Thanks.

Just received a shipment notice from Rythmik that my FV15HP has shipped and will be here on Thursday! Can't wait to start playing with the sub. For those waiting on subs, looks like the wait will soon be over.

And just in time for the holidays, eh... Post back here with your impression of your new FV15HP once you've got it set-up and dialed into your system. I have two sealed Rythmiks but I for one would like to read more personal subjective reviews on the vented models. Thanks...

I'm still enjoying my FV15HP. I think I got the last one before they ran out of amps. Sounds super clean like my old F12 and can put out the rumble effortlessly. Love it.

Hi Brian,

From conversations with Danny (and looking at his website) I see the 8 inch driver is now available.

The one Danny has is 16ohm and best used in a multiple driver configuration.

He indicated you were receiving a shipment with lower impedance.

I want to do a single driver, sealed sub (about 1.2cf) and wonder what would be the best driver/amp combo.

Thanks

Why are the new amps needed? Wouldn't one of the 370PEQ or 600PEQ amps work?

Brian, are you guys going to be at CES?

Hi -

Will the new PEQ3 amp be included on the F15 subs? Should I care?

What are the main differences vs. the PEQ2? I saw something about it having no high pass filter. Is the PEQ2 being phased out?

Hi
I just sold my SVS PB 12+, and I have setup a new 11 channel system in a space which is about 10 (W), 10 (H), 20 (L). My sitting position is about 10 feet away from the screen, and the subs will be located at either side of my TV console which is about 11 feet away from my sitting position - the spot for the SVS in the picture, and the other side will be used to site a 8 inch Velodyne Minivee (which I am thinking of using to fill in the mid-bass).

I liked the extension and SPLs of the SVS, but it felt a tad loose, and will like a new sub which is tight, deep and can give me that nice thump and rumble in the chest.

My question:

Will the F15HP be able to do this, or should I get the FV15HP?
I am concerned that the vented one is less tight.
Also will I need to use the Minivee at all?

Thanks

That is too bad for those who want a quality sub in a 2.1 system where there is no HPF in the pre-amp. It means those systems are restricted to 370watts (by the way, what impedance are your wattage figures for).

They've all been rated at 4 ohms so far. http://www.rythmikaudio.com/amplifiers.html

IMO:

1. The F15HP should be fine unless you really want/need the higher output of the vented design.

2. Probably true, but "less tight" with the servo circuit is still "tighter" than most other subs. I doubt you would notice the difference.

3. I would not, especially for midbass. You risk localizing the upper bass and destroying the image. It could be useful as another woofer, if your AVR can properly integrate two subs. Even then it may corrupt the clean sound from your new Rythmik. Use it elsewhere or sell it. Do not put it in a closet in case you might need it later; I have tens of thousands of dollars of ancient equipment in storage that would have been far better off in somebody's home...

Agreed^.

If your main reason for changing is to get a tighter sound, go for the sealed option. You can't make the sound tighter by adding subs later, but you can make the sound louder by adding another sub. Having said this, I don't think you will find an F15HP wanting for output in a room that size.

Ditch the Minivee. It will be more trouble than it's worth to integrate. Localisability and distortion are your enemy.

Thanks friends
I visited my local retailer, and the D15SE impressed me more than the F15HP in terms of the tactile rumble.

So I asked him if the F15HP does the same, he said it's tight, easier to place, but the FV15HP does all of the above, and more, except ported subs are harder to place.

In the end, I went with the FV15HP. The SVS PB 12+ has a lot of bass, but it felt flabby. So I wanted a unit with plenty of bass and yet was a tad tighter.

It seems the FV15HP can do this and keep a little in reserve. Fingers crossed though on placement as I only have one dedicated spot and crawling around for bass isn't an option since the position of the sub is pretty much fixed due to aesthetic reasons...

Will turn off the miniVee first and re-calibrate when my sub comes.

Really hoping the corner placement gets me that rumble and feeling in the chest.

Hi everyone

I've been lurking in this thread (and I've read the whole thing) over the past several weeks. I'm about to replace my stereo/home theater setup (trying to sell it now). I'm pretty sure I want the sound of sealed subs for the new system. Originally I was looking at a pair of Hsu ULS-15, but then I found Rythmik and began investigating. Based on what I've read, it sounds like I can at least match the SQ of the Hsu (and likely exceed it) for less coin if I build a pair of DS1501 or DS1510. I'd love to do a pair of dual driver kits (F25), but the budget, space, WAF might preclude it. And I don't really need it . . . not that that would stop me!

My current system uses a pair of 12" subs, each having two 10" passive radiators and a 500 watt amp. This sub is part of Phase Technology's dARTS system. I have not had a problem with output (never bottomed the subs), but the Rythmiks should get me an entire octave of additional extension and probably more output as well.

I'm not entirely sure what speakers I will be using (still investigating that), but likely it will be a large 2-way "bookshelf" speaker with an 8" woofer for the front soundstage. An Anthem MRX receiver will likely drive them. The room itself is about 1860 cu ft, but it also opens via three stairs up to a hallway. The total volume entirely enclosed by walls is about 3140 cu ft.

My time is probably split about 70/30 movies/music, but I do value the cleanest, tightest sound for both. I've attached a drawing of my room. What do you guys think? Will a pair of DS1501 do the trick, or should I pop for the DS1510? Or perhaps I need to stretch the budget a bit and duplicate a pair of F25! You can never have too much headroom . . .

I'd do twin DS1510s with the 600 watt amps. Like you said, one cannot have too much headroom, and rarely do you hear many folks complaining of too much, overpowering, tight accurate bass reproduction (especially for HT).

I have a single F15 (purchased this past August) in my LR, kitchen, dining room, foyer adjoining rooms. About 7000 ft3. It has punch but I'm thinking about a second F15 down the road perhaps for HT output authority. The F15 is so tight and clean, no boomy junk here. I did the first 15 minutes once again of the Master and Commander dvd just this morning, awesome cannon battle. In a room of your size, I think you would be well pleased with the 2 DS1510s (F15HP). For musical clarity, Rythmiks are the ticket. Very pleased with mine.

Hello all,
I am a very proud owner of a F12se. I have a question? Is there any switch on the back of the sub that forces the sub to cross over at 80hz, even though I have the cross over dial set to the highest #?

Yes there is, the "Low Pass" 3 position switch can do this when set to 80hz/24. If you are using an AVR (with its own Low Pass settings) to manage your sub, this switch should be set to Ext/12. The "Low Pass" switch works in conjunction with the "Crossover knob". See Rythmik's detailed description of controls below:

http://www.rythmikaudio.com/amplifier_controls.html

Hello thanks for the reply. On my sub it says
LFE switch all the way down (3rd pos),. AVR 12, middle switch ( 2nd pos) , And 80hz/24. Top ( 1st pos). So iAVR 12 the same as Ext/12?
what is the diff between LFE, and AVR/12?

Actually I just read that LFE switch increases the subs crossover range to 180hz.
