RTi A9 mid-bass help!!

For Tony B in Chicago...I just looked at the links you added for our friend and both are nice choices. I have question though with the parasound as the specs on the listing says 140 wpc @ 8 ohms which the rtia9's are and 200 wpc @ 4 ohms. I think the A9's can take 500 wpc and my question is...should you have something close? I have been looking hard at some A9's on ebay and some lsi 15's and 25's @polk online. I have a lot of questions about the lsi's and their appetite for 4 ohm power, what do you know.

for what it's worth, I prefer craigslist over e-bay for used gear as you get to go look it over and maybe use it some before the haggling begins.Main Family Room: Sony 46 LCD, Sony Blue Ray, Sony DVD/VCR combo,Onkyo TXNR 708, Parasound 5250,

You don't necessarily have to give it 500 w/c... i mean u can if you want but its always dependant on the application in which its used.
I'd like to get around 250-350 w/c for mine, but how would I run them @ 4 ohms?
I was talking to someone at Emotiva, I asked if it was possible to wire 1 positive & 1 negative from each tower together since 2 8 ohms wired in parallel gives 4 ohms and run the amp bridged in 4 ohms. He said he doesnt recommend it as it could possibly damage the speakers.... I was hoping to keep mine @ 8 ohms and drive 250-350 w/c to each tower. -

The speaker thing, you seriously do not want to do that and bridged amps do not want to see less than an 8 ohm nominal load.
You're also making a common rookie mistake by looking at a brand new shiny cheap amp while thinking specs are the end all. They are not. There's plenty of better used gear out there, just take your time looking and ye shall be rewarded.Political Correctness'.........defined

For 2 channel in that room, I'd suggest the LSi 9's with nice sub. Those other choices are too big for the room size.Political Correctness'.........defined

Different speakers are rated with different ohms. As I recall, your original issue was trying to provide enough power to play your music loudly enough. The best way to do this, is to power your speakers with a powered amps. You mentioned that you were considering the XPA-2 or XPA-3 from Emotiva which will give you the biggest bang for the buck. Many reviewers have commented about cranking up the music to the point of busting their eardrums, and the Emo amps sounded like the could still offer more volume.
Before considering other speakers, try getting an amp first. This WILL be your best investment ever. Any of the XPA amps will do you some good on those RTI-A9's. -
Thanks for the reply justlord.
Would the XPA-2 be a sufficient amp for the A9's? Would it do the towers justice or should I look into something bigger?
Seems like Emotiva is the best bang for the buck from a Canadian's perspective. I also looked into Parasound Model 2250 which could be had for just about the same price.
What do you guys suggest as the better choice? Please keep in mind that in Canada, the price of gear is much more expensive due to venders hiking up the price from exchange rates & also shipping to Canada is much more expensive. -
The Parasound is the better amp, period. On Ht you probably wouldn't notice much difference between the 2, but on music and at higher volumes, the parasound should spank the emo and is better suited for RTI speakers.HT SYSTEM-

what makes the Parasound a better buy? Just out of curiosity...
The Halo line-up is much more costly, but the 2250 isnt badly priced delivered compared to the Emotiva
I'll be using it for music, movies, & games... -
Better quality piece, a tad on the warm side of neutral sounding while the Emo is considered a tad on the brite side and so are the RTI speakers. The emo and rti combo may sound too brite for some is all I'm saying. Either one will power those speakers just fine though.HT SYSTEM-

Sounds good, maybe the Parasound is the way to go, especially since they are virtually the same in price bracket after shipping, etc & what makes the Parasound more convinient is there are dealers in Canada, whereas Emotiva has no dealers in Canada.
Thanks for the help

BTW, for the Model 2250 from Parasound, it has channel A/B, 2 speaker outputs for each channel. Would I bridge 1 speaker on 1 channel and bridge the other speaker on channel 2?

In just 2 channel, you would use speaker A only, if your going to use speakers a + b, or 4 speakers, then you will not get the most current to the front 2. Don't bridge the amp either.HT SYSTEM-

What would happen if I bridged the amp? I would essentially be at 8 ohms bridged wouldn't I?
So Just use 1 channel?
Would I be better off to buy a mono amp in that case?
If I do go with the Parasound and use 1 channel, it produces approx. 250x2... does this mean that if i use a right & left on channel 1 I would be doing approx. 62w for left + 62w for right? Or how does it work? Sorry for being a newbie.... :P -
All you have to do is read. Read the manuals or search around. No one is going to advise you to bridge ANY amp. That Parasound will be your end all for a very long time. Take a chance. We don't just BS around here with opinions and suggestions. People here know what works and how it's done. Your logic is to be more complicated though. Just plug it in and enjoy the music!

I think the reason why I make things much more complicated is because I'm much into big power car audio, and when I joined the Home Theater band-wagon everything changed. The way things are set-up & wired is totally different lol...
I was excited when I got a price for a Parasound Model 2250... then later found out it was a dealer price and I'm not eligable for it (since I'm not a dealer...). Now the price hiked up $700 for it to a grand total of $1,700 for it shipped. DAMN YOU CANADA!!!!! lol
Back to the drawing board to figure it out! lol... budget is a bit tight right now but I'm itching for the amp.
Question... Would the best choice be for me to use a 2 channel or monoblock for my application? -
Judging by bang for buck, not that the Parasound 2250 is almost 700 dollars more than the Emotiva-XP2, I think I might spring for the Emotiva XP-2, or even XP-1....
Hopefully it wont be too bright for my liking! Waiting for a call back from Tech @ Emotiva -

Well this is NOT car audio and while I know where your coming from. This is a much different world.
As to your question. Your best options for 2 channel is: A 2-channel amplifier OR Two (2 not 1) Monoblocks. You can't run a pair of speakers off a single monoblock amp. -
Trying to wrap my head around HT is harder than I thought :P
Just for my own knowledge...
Why do some monoblocks come with 2 positives & 2 negatives then? Would it not be to connect 2 speakers?
