Yay! Congratulations and welcome to the family. I too have a FV15HP and absolutely love it. I listen as much to music as I do watch movies and this sub does it all extremely well. Enjoy and report back once you've put a few hours on it.

Sounds like wireless isn't the best option. So now I'm between rerunning 50' of RCA up through wall, across the ceiling, down the wall, etc...or do I go with his route of the Balun and Cat5 connectors. It's cheaper to go with RCA, but that's probably a pretty rough run to restring it.

50' is really long. Is there any way that u can run the RCA along the bottom of the walls. It will shorten the cable long quite a bit and esthetically, is not looking that bad either.

I'm sure I could, but at that point why not just get the balun and use cat5? All of my equipment is in a closet next to the room too, so that makes a run on the ground a little trickier; I'd have to go under the carpet at some point.

Don't worry about a 50ft run. I have two 50 footers and two 35 foot RCA runs to my subs without degradation or foreign feedback etc. $11 plus shipping for a decent 50ft RCA from Monoprice. If you have the access to pull the cable that might be the best. The Cat 5 route is something I've never used for a sub, but it too woud probably function fine. I'm not sure of the cost of the connections yet all you can do is try it, see if its degraded or has any feedback or hum. Do you know if its shielded Cat 5? Depending on the run and its proximity/orientation to AC power/romex runs it may not matter.
Let us know how it goes.

Congrats!

Are you planning to run your sub off the pre-pro or receiver's dedicated sub out? If so, that's a low voltage circuit that would probably do just fine with the Cat5. It's a little unorthodox to do so and the only problem you might encounter is..........even though Cat5 is twisted wires it still doesn't have any shielding so you might pick up stray RF noise on a run of that length. Others with more knowledge on Cat5's attributes might chime in and correct me if I'm wrong.

I can't wait to get into my house, so I can hook up my 2nd Rythmik LV12R. It has been sitting unopened in a box for a few months. One impressed me, so I'm chomping at the bit to see what duals will do.

I admire you as I cannot do that. I always open my toy the minute it arrives use it or not at least to know it is in good shape and working.

I expected to run it into the receiver (Pioneer sc-61).

If it's better to run something else I'm open to giving it a shot. There's a speaker wire run to that location that I could try to attach it to to do the pull...and hope it doesn't fall off or get caught. #ducttape

I really wish Rythmik (Brian) would chime in on the cat 5 cabling for sub signal input. I'm sure he has seen it, tried it, or has some valuable input on this. A bit unorthodox but thats not to say it might work out fine for the subwoofer input. I've never tried it or seen it myself. He must be on vacation with the family or traveling or something. I sent him a PM on another subject a couple days ago, waiting for a reply.
RCA cabling has some shielding, usually a foil wrap surrounding the two conductors. Cat 5 to my knowledge has none.

It has been rather difficult. I did pick up some Infinity Primus P363 towers and the matching center channel PC351 to tie me over somewhat smile.gif

Love these speakers by the way! Great natural sound that is not exaggerated with some nice low end. It's hard to explain as I am somewhat of a newbie when it comes to home theater, but my ears like what they hear.

Not the greatest pics, but they blend beautifully with the black oak of my Rythmiks.

Both CAT5 and CAT6 can be purchased shielded. The price can be substantially higher thus many home runs are not. As long as its not run parallel/in close proximity to high current lines non-shielded is typically fine for most applications.
I too have never seen it used for a sub but as Torqdog mentioned it is low current and the CAT5 to RCA bulans may even utilize more than two leads. I would definitely give it a try vs attempting to pull an RCA cable. A quick search found audio RCA to CAT5 bulan/connectors for less than $20 each. This little conversation has given me some new ideas.. biggrin.gif


Cheers

I spoke with Brian about this and what he said is if the Cat5 cable is shielded, then it should work without any problem. But if it is a not shielded Cat5 cable then you will probably get a hum, most if the Cat5 is near or it's running aside a high current line. I would give it a try before run a RCA or coaxial cable.

I use these at church with shielded Cat5 over 300 ft with no problems.

These speakers are a steal for the price.

I know for a fact this works..Our touch tunes juke box computers have rj45 audio outputs for zone 1,2, and3. so we use a cat5 cable from the computer to a DI(Digital cat5 to RCA Interface) box.This allows us to hook up a external amp or subwoofer via rca or lfe inputs.

I bought UMIK-1 miniDSP
I will do later schedules
post #10040 of 15242
If the only thing on the CATx run is the subwoofer feed, why are baluns needed? Unless to break a ground loop... I'd probably pick a pair of wires in the cable, put RCA's on each end, and hook it up to see what happens.

Hello everyone,

I borrowed my friend's Denon 1911 to test and compare with my Yamaha V1800. The subwoofer used is F15HP.

I noticed a big difference in the bass produced from the Denon 1911. All the 20hz bass that I had heard from the Yamaha 1800 seems to have disappeared. I tested with Audyssey on as well as off. All speakers are set to SMALL. The subwoofer was never moved. A good demo scene for this is from X-Men First Class; the scene where Magneto extracts a metal filing from the banker's teeth.

Do you guys think it's because of Audyssey or something else? Maybe it's a low end AVR that can't produce sub bass??
post #10042 of 15242
Try re-running the calibration. The AVR does not supply significant power to the sub so it is most likely something to do with Audyssey. It is also possible bass was boosted by the Yamaha, of course.
post #10043 of 15242
Yes, it could be Double Bass or some other bass management / eq setting in the Yamaha and/or Denon.
post #10044 of 15242
One day I will save enough coin for a Rythmik sub.

Very unlikely any bass deleted because of an inexpensive AVR. Like other posters said, more like a setting such as bass boost or bass enhancement, or perhaps LFE assignment. Instead of using a demo scene, you can download test tones and either put them on a cd or thumb drive. Specific frequency test tones much more reliable....link below.

The strange thing is when I disabled Audyssey MultEQ, the deep bass still cannot be heard.

When I used the Yamaha V1800, I didn't boost the bass at all. The deep bass sounded pretty good, it can be heard and felt when it needed to be.
It didn't overpower all the other frequencies.
post #10047 of 15242
Did you re-run the cal? Try a couple of times with the mic secured on a tripod if possible and in a couple of positions. I would check all the settings on the Yamaha, including things like running the sub with the mains, and check the trim levels on the sub. Maybe the Yammie had the basss boosted just a little, or Audyssey may have more filters and sensed a peak (dropping the level). If nothing else try boosting the sub's gain a little.

Check all of the speaker settings, such as speaker size Large/Small, LFE/bass management (how the receiver routes the bass from Small speakers), etc. There's probably a setting somewhere there that you are missing, in one of the two receivers.

I was thinking about getting a LV12R for my 13x17 living room will this be enough or will I need something bigger?

I recently did a review on the LV-12R, and ironcially my room is also 13x17. If you're interested in one persons assessment it can be found here.
