sub links

[redd454]

i have two 12" monoprice powered subs, both work great, these subs have both rca inputs and rca outputs, manf. sugg. fo linking to link to rca outs from first sub, to rca in on secons sub in rear and so on, second sub is 50' i am running ex. cables, sec sub is barly audiable, and does not hit like the front ,i checked the sub by moveing to front, works great, but whent in rear does not, i have also tried wye adpt bypassing line outs still the same, everywhere i look says these links should work,even at a 100',so what's the deal?

That's a tough read, but I think what you're doing is daisy-chaining the subs. Never a good idea, better to just use a splitter at the source and send the signal direct to the input of each sub.

You say the second sub is 50 feet away? Then your level problem is likely just a matter of being too far away. Move it closer or turn it WAY up. You are also probably having phase cancellation problems with those distances. Try altering the phase on one of the subs to see if that helps.

my room is extreemly large, have read agout people placing subs 75 to 100' no problem, i'm using good cable, yet i placed #2 sub where #1 is, to be sure it's working' when i do' it performs the same as # one great, bu not at 50', is there an inline signal booster that can be used?

I'm no expert. Post this in the subwoofer section and there you'll get more attention from the folks who like bass a lot more than me. Expect more questions, though I can tell you a subwoofer that's 50 feet away isn't going to sound as loud or be as forceful as one 10 feet away if set at the same level. The signal is low-voltage and not subject to distance the same way soundwaves are.

Are the people putting subs 75 to 100 feet away using much larger subs with far more powerful amps? Probably.

Physics...can't escape it.

What are the distances from each sub to the listening position? I'm assuming the cable run is much longer to go in/along walls etc than the actual distance to the listening position, but not much info to go on here. Sounds like a very large room for a couple of small subs in any case. Knowing more about the steps taken to set each sub up for level/delay/phase would help, too.

12" sub's 150-250 watt, wire's run top of floor testing mode,still haven't reached satisfaction, i may boost gain on signals by linking three amp's one per sub, but first i'm trying splitting signal at source

The wattage of the sub amp has little to do with it. What is the distance from your primary seat to each sub where you plan on placing them? How did you choose the locations? Not sure what this means "boost gain on signals by linking three amp's one per sub". What are the settings in your avr as well as on each sub?

If you have 75 to 100' of sub runs, your going to need a bigger sub or 6.

I doubt that what I’m going to add is the case here but I’ve tried to daisy chain before, and found the output voltage on the output side(to the second sub) had much less voltage. I split at the source and it worked fine after that. Just thought I’d muddy up the waters!!!

Looking at the monoprice blurb on the sub they actually suggest using both inputs, too, which may give a slight gain advantage as well.

Additionally, the subwoofer has a set of right/left Line Level inputs. If using a standard stereo system, without a special subwoofer output, you can connect these to the left and right line level outputs on the amp. The subwoofer will then combine the signals to process the mono bass signal it needs to drive the speaker. If you are using an amplifier with a single mono subwoofer line level output, simply use an RCA "Y" cable to split the output and send it to the two line level inputs on the subwoofer. The Line Level outputs can be used to daisy chain additional subwoofers to provide even more room-filling bass!

one main front sub 35' from couch, 15' from source rear sub, 10' from couch, behind me, third sub. ri side of room around the middle, already had two subs needed more to fill room, so i am attemting it,maybe wrong, but from what i've read it's not rocket science, and i'm 63 have been in audio both sides of the bench a long long time, just getting back into

What is the total cubic feet of the room?

Lol

That's somewhat confusing...as to the relative positions of subs to couch and not sure what you mean by source.

What are the overall dimensions of your room? Got pics or a diagram?

thank you,if i want to split it three way's at the source, what splitter would work i could only find one with three female rcaxone mini but i have an adpter to take that to rca male, if it does not sound good i still have alot of amps i could link, just don't want to get into all tha,someone said split at source rather than at the sub, that does make since, also i have a bearinger a/c cross/with input gain out put gain and sub out poss. could use somewhere, well getting back into after all these years/xlr conn. ect. is quite fun, thanks for the input

I have a hard time just reading what you write and understanding what you have and where. Capitalization/complete sentences/paragraphs would be nice.

I'd piggyback splitters if needed (and have done so). Don't understand the "alot of amps i could link" or "i have a bearinger a/c cross/with input gain out put gain and sub out" at all.

 

[redd454]

source my man, is the sub out at the amp. point of conn.

 

[redd454]

55 longx 40' wide' room size, i have alot of unused eq. surly i'll get it some way,however this imput from you guy's is great, the heads of the many are better than the head of the one lol

 

[redd454]

yes sorry about cap's punc. i'm good to type at all,one finger looking at keyboard, not checking for mistakes i'm sure it's a challenge

 

[redd454]

hey,just a thought, i also have two rear tower spk. close to rear sub, how bout if i patch through high side useing spk wires to feed sub. i always use sub. out, never tried this how does a sub sound when fed by spk wires?
