Can i bridge this reciever?

[quakefiend420]

here's a link to the manual

reciever model is an onkyo tx-ds484

can i bridge left A and left B to one speaker and right A and right B to another speaker?

the tower speakers i just got are 150w rms and the reciever only puts out 55@8 ohms...i have to turn the volume up way too high to get decent output from them...however, it says 6 ohm minumum load on the back of the reciever...but that would pull 8 ohm on each channel since they're 8 ohms at the terminal...right?

i just don't wanna burn the amp up

thx

link to how i'm planning to wire it...yes my paint skillz rock

The way you're suggesting would simply be bi-wiring, but this will be more than likely detrimental to your receiver as you're taxing the amplifer stage more than you're making a better sound. Bridging an amplifier in the traditional sense would be done on the amp "internally" and then used in a traditional channel-to-speaker, instead of two outputs to one input.

With modern receivers, people have been taking unused rear surround channels (6 and 7) and bi-amping speakers by taking the pre-outs of said channels and looping them into the multi-channel ins...some people think it's an improvement, some don't. I say that if you're so worried...buy an actual amp. A cheap adcom, acurus, rotel, whatever will only cost you 100-200.

Lastly, don't be so concerned on the numbers on your speakers...but you're right in that your reciever's a bit on the weak side. 55W@8ohms will probably be like 80W@6ohm, but then you're driving the amplifier harder because it's drawing more current which it wasn't designed for. Pushed too hard, it'll probably force your receiver into a protection mode of some sort...if your amps are running really really hot, I wouldn't do any more to them.

I don't know if anything I just said makes any sense.

i just want a little more power...the speakers are only getting to about as loud as the standard tv speakers...granted, bass and midgange response are a lot better

i just want a little more volume...

i was gonna try it and see if it is an improvement over what it is now...the amp has decent ventilation.

i just want to make sure i'm not gonna fry anything in the process of experimenting

...

that they can handle 150w of constant power each

the 55w that the reciever is giving them now isn't loud enough for my tastes...i guess the sensitivity of the speaker is kinda low(<85db i'm guessing)

no i'm not your garden variety dumbass, i just want to make sure i'm not gonna toast my receiver

Do you know what "Elite Member" means? Guess not.


quakefiend420:

I doubt that it's a good idea, though I won't say for sure that it will or will not work. Question, though - aren't the A/B speaker options either one or the other, or reduced output if both are selected? I doubt both A & B are seperately amplified channels, so trying to bridge them would be pointless regardless of it being possible. Again, I don't know that amp, but usually A/B is either A OR B, or A and B at 50/50 power.

good point, i didn't consider that

i guess i can take a closer look at that manual and find out right quick, though

Seriously, I don't take to noticing anyone in particular, but recently you've been standing out as a real douchebag. Perhaps the mods need to clean their spectacles.

I'm going to take this opportunity to say that I don't know what will happen if you try it or if you will get any gain from it.

I think EvilYoda's suggestion of getting an actual amp would be your best bet if you really want more power.

 

[spidey07]

short answer.

Yes, but with bad results.

want more power? get more power.

Trust me, us big boys have tried to squeeze more volume/power out of things for years. There is no free money and there is no free power.

If your stereo/HT isn't proviging the volume you want then you need more power. an onkyo receiver is going to barely provide conversation levels as far as volume is concerned.

Want more volume? Purchase an amp off of e-bay.

 

[EvilYoda]

No, he's right...I was also right that my original reply didn't make much sense.

That's why I said that you'd just be running your amp harder w/o any positive effects.

You do know what that means. Many people see that spec and think the speaker puts out 150 RMS.
Both your receiver and speakers are on the low end. Running them as you diagrammed will likely cause problems or shorten the life of the receiver.

that's what i'm thinking...i was looking for a temporary solution

the reciever isn't all that great anyway...i was going to replace it eventually, regardless...i guess that will be sooner than later

i have a 100w rms X 2 JVC amp from the early 80's in my closet, i just don't have room in my entertainment center for it and the reciever...and it's too old to even have video i/o

oh well, i'll figure something out, i suppose

thx everyone :beer: 's all around

i would think you would have known i had some clue of what i was talking about, considering i was pretty clear in my OP, but that's cool

and yeah, i know this is low-end equipment...the kenwood soverign and my jbl's are in the bedroom...that's just the secondary equipment in the living room

i'll upgrade eventually...it never ends...between cpmputers and stereo equipment, i blow way too much damn money on electronics

 

[olds]

When I got my Denon 3805 I felt it was underpowered. I added a Parasound 200 X 2 to the pre-outs for the mains, for music. It really bumped up the system a notch.
You'll be dropping your impedance and risking your receiver.

 

[Eli]

Geez, I'm perfectly happy with my vintage Dynaco SCA-80Q conservativly rated ~30Wrms/Ch.

Granted, the speakers I have are only rated at 30Wrms, so they compliment eachother nicely..

But it has no problem shaking the house...

Music wattages are confusing.
