I was thinking about going with dual f25's, however rythmik said that's way overkill and they are not shipping f25's right now. My main focus is on music so I prefer sealed enclosure, however I do watch a lot hd cable. Not really into watching movies, mainly sports, one hour shows etc...So now my choice is either 2 f15hp or 2 e15hp. My budget is around 2k and I got the e15's with the 550 amp down to 2130. Any suggestions?

Well now, that certainly happened rather quickly. You saved up 2 grand since this morning? biggrin.gif

If you're budget is 2k -- and you can get the E15's for just a little over it -- then perhaps that's the best way to go. With strategic placement you should be able to flood a 2400 ft^3 room with deep bass.

Thanks qguy, been looking at the F12 for a minute now. It looks to be the one for me. Hookups still blurry for me.
Now I would run b&w’s off the arcam, then use L&R rac pre amp out to L&R rca in on sub,, right?
I’ve been doing a lot of reading and seen L&R used or single cable used or L&R in to a Y.
Which is best? And does it matter if single cable is in the L or R rca port?
Thanks, try to get my mind around all this.

Okay, in a cloud of ignorance, I ask; why don't you upgrade your AVR?
post #8885 of 15196
Still works and sounds great. And may be a little sentimental I guess to,, after all I’ve had new from 1999.
post #8886 of 15196
Allow me to be an AVR friend. Much has happened since 1999 (fourteen years) it's time to upgrade.

As encouragement, I recently upgraded to a Marantz, SR5007 from a perfectly fine working AVR and I'm glad I did.

Just saying.

Yes it’s a good idea, I agree. If I by a new avr I won’t have the funds to pick up the f12. So, if the arcam can do the job now them sweet. Oh ya,,, my wifes keeping a close eye on me, so little at a time,,, yes. smile.gif

I understand. One needs to choose what they choose, one item at a time.

Currently, I'm playing with the middle ground, buying measuring gear and stuffing the cabinets with poly-fill. From there I have to decide if I want to add a subwoofer or add an amplifier as we just upgraded the size of the TV and the center channel.

Baby steps.

I have had the coin saved to upgrade for awhile, but its hard to pull the trigger on something that costs 2k without hearing it first. so being gun shy i went the budget route.

Ok so I can get the e15's with 550watt amp for 1914.00. thats 200 less than with the 600watt amps. website claims .5db differrence between the two? Thoughts??

Up to you if you think the extra 0.5 db is worth the money. I opted for the 550 watt with the FV15HP.

Sounds like a good deal. Don't think you'll notice the 0.5 difference.

Didn't know Rythmik offered the H550PEQ3 option for the E15.
post #8893 of 15196
Hey guys,
I'm looking to replace my Velodyne minivee 10 with bigger sealed unit (I was previously looking at a used DD-12 for ~$1100). My living room is 14X25X8ft, I use corner placement with carpet and an Auralex sub-dude. I prefer extension over max SPLs as I have small kids and listen to quite a big of chamber music (pipe organ). The Rythmik site says the F12 extends down past 20hz and is only 3 down at 14hz...can anyone verify that? Also, I see on here you guys talking about 550watt amps, all I'm seeing on their site is the 370watt, do you have to call them for the upgrade (and how much is it), also, does it only add max SPL or does it increase excursion and extension?

Thanks,
Cory

Two F12 or two F15 for left and right would be another option.

They may not. I just looked and did not see an option for a 550 watt on the E15.

post #8896 of 15196
Single cable to any of the L or R inputs of the subwoofer works for the HT amplifiers as it has a dedicated subwoofer outputs, Since your running a 2 channel amp, you might as well use 2 runs of RCA to the L and R inputs of the subwoofer.

Another option is using the speaker level inputs. You connect another set of speaker wires from the Speaker B of the amplifier and then connect the other end to the Speaker level inputs of the subwoofer

post #8897 of 15196
From reading everything, I get the impression rca hookup has a better cleaner sound then going through the speaker post’s. is there any truth to that? Or they basically work and sound the same. Then again I can try both and see.

I see the line levels are filtered at 80 hz so i'll use rca's over the speaker wire.

post #8898 of 15196
I tried the speaker level hookup for a year and a half and then tried the RCA level and could not hear any difference.

REL another respected subwoofer manufacturer, believes that speaker level connection makes the best connection as you do get the power amps character (and distortion ???) being fed to the subwoofer which makes for better integration, whereas Rythmik suggest RCA level for less distortion.

Thanks qguy for all your input. I see more clearly with you help. Never thought I’d have to spend a couple of weeks reading up on sub’s just to buy one:eek:
I went to the order page of the F12, they say it comes in HONEY OAK, put when I go to buy all they have is the black.
Does anyone know if there no longer selling the honey or just out or what? mad.gif

Correct, with a two channel amp with preouts you run RCA interconnects from the L&R preout to the L&R line in on the sub. This allows you to use the sub's crossover which is a must since a two channel amplifier does not have a built in crossover. This is how I have the two channel system in my office set up. Do not use the LFE input on the F12 it is designed to be used with an AVR that has bass management built in.

Are you saying the line level preouts from your amp are filtered at 80 Hz?

When I looked at the ARCAM Alpha 7 amp manual it didn't say anything about the preamp out channels being filtered at 80 Hz. The manual says that these preamp out channels can be used to bi-amp the main speakers which means they are full range channels and will pass the entire spectrum supported by your amp (Say 20 Hz to 20kHz) to whatever they are hooked up to. To filter the signal you need to use the F12's crossover. You choose where to set this limit, anywhere between 25 and 100 Hz, whatever works best with your speakers. You can use the F12's crossover with either the high level (speaker) or the low level (RCA / line in) inputs but not the LFE (1 or 2) inputs.

You are right. Thanks for your input; I feel I have all the pieces of how everything’s going to work. It only took me a couple of weeks to figure it out. lol smile.gif
I think I’m ready to buy just waiting on word on the honey oak.
i like these forums, everybody is so helpful.
thanks
post #8903 of 15196
You're gonna love the F12. I have one and am thrilled with it.
post #8904 of 15196
There is an RCA line out with a 80hz Filter on some models of the Rythmik Subwoofer. When you feed the Rythmiks using full range signals from the PRE-AMP, you can use the 80hz Line out to provide a filtered signal to your main power amp. This would protect your main speakers from low bass specially when your main speakers is on the small side. I use this when watching movies and disable it via a switch I made when listening to music.

I am thinking of changing my sub and would appreciate some comments:

currently have an F15HP and want to add a second sub: Preamp is Marantz 8801 with Audyssey Pro kit

wife says a second F15 is too big (it is the E type slightly smaller cabinet) , and I guess I agree so the idea is to get two F12 signature series

My question is if there is any risk in making this change? I do feel two subs will help but am a bit concerned about going to the smaller size

TIA for any input
post #8906 of 15196
By the way, what is the motive for the change, F15HP too big or you need more output ?

This might help...

The output at 20 Hz is shown relative to F12.
* F12: 0db (baseline)
* F15: +2db
* D15: +2db
* FV12: +3db
* E15HP: + 3.5db
* F15HP: +4db
* FV15: +7db
* FV15HP: +9db
* F25: +7db

motive is I feel I might get better coverage with 2 subs, and wife says 2 subs will make room look more balanced: can't argue that smile.gif

so the correct model I have now is E15HP
post #8908 of 15196
"MIGHT" is something you may want to take out of the equation before changing anything. If your getting good response now, I would not change anything, unless your upgrading to two better subs.

I read your above to be, the wife likes things to be symmetrical. I've read several times that symmetrical placement of subwoofers, equidistant from the main listening position is a bad thing. Asymmetrical placement will give better sound wave distribution. Do you have room measuring capabilities? If no, there's no way you'll be able to gain maximum benefit of any subwoofer system, you install in your listening venue.

From personal experience, I've found, for our room, a third sub is needed as opposed to one or two and based on all the graphs I've seen posted in the many threads on AVS, most here would benefit from a third or fourth subwoofer which will even out bass sound waves and create a larger, smoothed, listening area so all can get decent subwoofer sound, not just the person who happens to occupy the MLP.

(The wife's listening position, a few feet to my seated right, is terrible by measured comparison but lucky for me, she doesn't know she's in a terrible location or otherwise, we'd have to switch seating positions) tongue.gif

Personally, if possible (the budget will allow), I'd recommend keeping the FV15HP and pickup an additional pair of Rythmik, E15's or go with one E15 with an eye on a second one at a later time when the budget will allow for the adding of another E15.

I thought I would share a recent experience with Brian Ding and Rythmik. I purchased a little over a year ago a FV15HP and have been extremely pleased with the sub (and the company). I had (as many of you I'm sure) gone through the threads and evaluated what you could about each company and it's product line. In the end I had the FV15HP and the HSU VTF-15H on my short list. Obviously I went with the Rythmik. Here starts the story with a quote from my build thread.

Quote:
Well thought I would come here and drown my sorrows. I was doing some demoing in the theater watching the AVS Demo Disc 2 by Scubasteve and was going between How to Train Your Dragon, Cloverfield, and WOTW, I normally do my demoing at -19 or -18 (Yamaha Aventage 1010) and tonight I was listening watching at -14 or -13.5. About half way through the WOTW demo I noticed the lack of the sub. I stopped the clip and heard a loud humming coming from the sub and then I could smell an "electrical" type of smell. I quickly unplugged the sub to eliminate anything else going wrong/bad. I then called Rythmik to see what had happened. Brian (Rythmik sub guru) actually answered the phone (how's that for CS) and I described my tale of woe to him. He requested I send off an email to him and I included a few photos of the amp to show how it was set up. He said he would take a look at everything and see what he could come up with and would provide some suggestions on how to check to see if it is the amp or speaker driver. So as soon as I hear back Brian I'll keep all of you updated.

Sitting here in a puddle of my own tears...........lonely and subless. The horror of it all......................................

I never realized how empty the world feels without LFE.

After looking at things Brian determined that my driver was shot and he was also concerned about the amp. He requested I ship the amp to him so he could check it to make sure is was in proper working order or if there was something wrong it could be fixed. The only thing he requested was I pay for the shipping and he would cover the amp repair (if necessary) and replace the diver at no cost to me. Needless to say I was very happy with this arrangement. I shipped the amp to him and upon his inspection he determined the power amplifier module was bad. Brian did not elaborate on if the blown driver caused the amp issue or if the amp issue caused the blown driver. Either way it was repaired. Brian fixed the amp and sent it back to me along with a new driver. I couldn't be happier with the way the situation was handled and I feel this is a testimony to how Brian Ding and Rythmik feel about and handle their customer issues. This is what customer service it really about. Kudos to Rythmik, it's a great company with a fantastic product (but you already knew that didn't you).

Thanks to Brian and Rythmik I am now happily enjoying my sub again.

Regards,

RTROSE
