rti12 bi amp with tx-sr608 ?

deseroner

ok i just got rti12's they sound great i have 7.2 system, i want to get the most or a little more juice out of the rti12s subs. i want to bi amp ,but on a budget after getting these bad boys,i was wondering where can i get a 200watt amplifier to power these. looking for something under $250 . anyone can recommend a good amp for a good price. i saw this one ,any good AudioSource AMP200. i have onkyo tx-sr608 reciever.

The 608 doesn't have pre-outs, and is not able to integrate with a separate amplifier. You'd have to jump up to the onkyo 70x series or higher, and add that to your budget with the amp. Even if you scour the used markets, you'd be hard pressed to keep this project under $250 for a 200watt amp and a new receiver. If you you were able to pull all this together for $500, I'd say you got really lucky.

Not trying to burst your bubble...just being realistic

Good luck!

edit: You could probably sell the 608 and break even on an older Onkyo 705, 706, 707 in the used market. If HDMI 1.4 isn't important to you (ie no 3DTV), its a move that makes sense IMO.

Depending on your budget, that cs1 isn't doing you any favors in keeping up with the 12's. Look for a used pioneer elite sc series receiver, no amp needed and will power your speakers fine.
That said, how do you have these crossed over with your subs ? Lower the crossover point if you want more to come out of the 12's. You have them set as large or small ?
That 608 in 7 channel surround is probably only feeding them around 30 watts, time for an upgrade or keep the volume reasonable until you can.

it says on onkyo site you can bi amp fronts http://www.us.onkyo.com/model.cfm?m=TX-SR608&class=Receiver&p=f

Yes the 608 can bi-amp,but theres no need..It wont make a difference to the sound.Best bet for you,is to forget about bi-amping and just get another AVR, i went through the samething as you,and ended up buying a Pioneer SC-25 and put the 608 in my bed-room as a stereo set-up

The 'bi-amped' configuration they referenced isn't a true bi-amped set-up. It simply pushes the LR signals out of a set of the surround channels, allowing you to run the full-range front channels through the top and bottom binding posts of your speakers. Because you're still drawing from the same power source in this configuration, it isn't techincally a bi-amped set-up...its a bi-wired set-up.

A true bi-amped set-up involves passing the signal from the pre-outs of a pre/pro or receiver to a separate amp(s) (ideally two identical amps) via RCA cables. Without pre-outs, its not possible to pass a signal to an external amplifier.

edit: I don't blame you or anyone for making this mistake. AVR manufacturers are being a little deceptive in how they market this feature IMO.

Bi-Amping is not going to help you on this one.

You need a new reciever at the very least.

If you Bi-Amp on this reciever, you will cause the reciever to put out less power channel. You are already giving the RTi12 minimum power to operate on. You don't want any less than you already have going to each channel.

alright , i am selling my sr608 for nr708,it has pre outs.that should help me right. 110 watts per channel, sr608 is 100 but no pre outs for fronts.

deseroner

plus i use my onkyo to control all my components. all hdmi 1.4 cables

You still may want to pick up an amp for those 12's. Keep in mind that 110 watts per channel is not 110 watts per channel when you drive 5 or 7 speakers. Look into upgrading the center channel too,keep an eye out for a used one in the FS section.

deseroner

ok looks like i am getting a nr-708, ok have another question, what amp can i get just drive the rti12's ,this is for movies(bluray,cable receiver,ps3) and music, the receriver is 7.2 , whats a good amp from $250-400 range . i saw audiosource amp300, will that work.

deseroner

so basically I can run the Audiosource amp300 power amplifier (300 watts 2 channel) for rti12's , will it heart the surround aspect of it, or not at all.

deseroner

so a carver m1.0 is also a good a amp to power these speakers.

Ewww...audiosource. I rarely knock on makers of amps, but these guys would be the ones to knock and then some. I'll tell you why...

1) Their units are tiny. Tiny. That means either heat buildup or it doesn't produce much heat (i.e. energy), which leads to:

2) They inflate their wattage ratings bigtime. How bigtime? That 300 watts/2 channels is into 1KHz at 8Ω. It isn't even rating at the full bandwidth, but a mere test signal at one specific frequency.

Realistically with the Audiosource amps you'd be lucky to get even half that power to your speakers when driving the amp just below its clipping point.

You'd be better off going the route of an Emotiva XPA-2, or two XPA-2s, each one driving a single speaker in bi-amp mode (left output to bass section, right output to upper array). A single XPA-2 will sound far better than any Audiosource amp no matter which dimension you're in/from. Two XPA-2s in the configuration I noted gives you both the benefit of bi-amp and zero crosstalk between channels. It's the latter that will give you the most sonic improvement. You'd be surprised just how much two channel and front channel soundstages open up when there is no crosstalk between them. Do note that you'll need a Y-Splitter from each pre-out as you'll be sending identical signals to each of the L/R inputs on two separate amps for a total of four outputs from the AVR (Y-splitter on L -> Amp 1 L input and Amp 2 L input, etc).

The upshot of using an external amp (or two) to power the fronts, even if not in bi-amp mode? The AVR's power is then only used by the surround/presence channels, and the power going to them is much less constrained, thus they can actually receive the full benefit of the AVR's capabilities since the fronts are offloaded to external amps.

Just whatever you do don't use Audiosource. Every time you do a kitten is punched in the face somewhere. Or somebody purposely makes themselves deaf. Either way. :P

The Amp300 is 150X2 and isn't the last word in refinement, but it's 2 ohm stable and is of respectable size and weight. Their little AMP/One As were 80w X 2 was very flat and ran my SDAs with no problems for awhile. They are a budget solution that you can find used for < $200 if you look (the 300) and for that price it's just fine. A buddy of mine has 2 of them and an XPA 3. I wouldn't pay retail for one, but I wouldn't kick it to the curb either.

got me carver m1.0t 200watt per 2 channel and also nr708.
