Will Polk Audio RTi A7 output good sound with DENON X3000 and Bi-Amplified?

I can say, I just upgraded to a NAD C375BEE (150 watts/side) with RTI A7s, the low end is outstanding. That being said, on songs with extreme low end such as Eric Clapton's "Come Back Baby" I have heard the woofers bottom out a few times. Given this is at pretty high volumes however nothing too ridiculous. The RTI A7s have their limits this is for sure.

Really? If thats true that is good news, I have 58 days to take it back...The sound seems to be an empty "wump" that can be heard when a bass string is hit.
-
Wow, well now that I know this isn't something I'm just going to have to accept, lets go about diagnosing this. The amp is 150 watts per, I have a hard time believing its clipping. The speakers were bought second hand...could there be a preexisting issue? They sound great with most songs
-
It's about current, not watts.
Spec says, "Peak output current >50A (ref. 1Ω, 1ms)"
So, that's 50 amps (current), which isn't bad, but that spec is at 1 ohm for 1 millisecond, which means in reality it's a lot less.Political Correctness'.........defined

So what would you recommend...what in its price range can beat it?
-
That NAD has preouts it looks like. Lots of amps under $1k would have significantly more power.afterburnt wrote: »They didn't speak a word of English, they were from South Carolina.

Would the Emotiva XDA-2 with the XPA-2 smoke the NAD? This would be cheaper than the NAD to boot.

RTiA's and Emotiva combo will make your ears bleed.
B&K would go nicely with them.afterburnt wrote: »They didn't speak a word of English, they were from South Carolina.

Not trying to hijack this thread but I listen mostly to jazz and when I listen to other music it's certainly at AC/DC BACK in Black concert tour volume levels. I know it's been said that RTia7's need lots of power and it seems no way that Yamaha CA-2010 power won't cut it according to most. Are you guys sure it won't for small ensemble type jazz?
I believe the same... I have my pair of RTiA7 connected to a DENON X3000 AVReceiver (105w p/ch), I was said that is not enough power (RTiA7 can be used up to 300w). But I've been testing them during 2 days, and I couldn't go further than 90db volume and just for one theme, all my furniture and the wood floor was shanking, my DENON's control was jumping over the table, and I live in a department. I like to hear them between 50db and 70db, and just sometimes go higher to about 85db or 90db.
They are just great. There are some songs where RTiA7 seems to have a little too much bass, maybe in the future I will check some configuration.
For music Im 100% sure I will not need subwoofer, not even for electronic/dance music.
For movies Im 99% sure that I will not need a subwoofer, maybe just for explosions but that would be at the botton of my "shopping list". -
Is that because Emotivas are bright? B&K and Parasound amps are much more expensive, I guess you get what you pay for.

Alright thats what I'll try to do, out of curiosity what kind of amperage would I be looking for in terms of current that would be sufficient for the RTIA7s? and would it be peak or continuous
-
Alright, you guys have been a big help and opened my eyes...right now it's looking like the NAD is going back (Crutchfield 60 day satisfaction guarantee) and I will put that $1600 to a pre and power amp that can handle these towers.

Which was your previous amps? how much power?
I have a DENON X3000 and I cant use it over 90db (too much loud), why a more powerfull amp is needed?
Thanks -

You don't have to get separates, there are plenty of integrated amps that easily outperform any number of separates.
Take a look here, http://app.audiogon.com/categories/integrateds-solid-state
Something like the Musical Fidelity A5 integrated would do quite nicely, 250 wpc with 75 real amps peak to peak. A used one should run $1500.00 or less.Political Correctness'.........defined

The integrated mentioned above is a great idea and Musical Fidelity should be on anyones short list. Though may be a tad overkill for A7's, would carry you through many speaker upgrades down the line.HT SYSTEM-

I really don't want to spend more than $1600...just can't. I was thinking of going with a smaller integrated amp like the RA-12 (if only the damn thing had PC USB) that I could take with me to my dorm room and hooking a nice b&k or parasound power amp to its pre-outs with my rti a7s at home or in an apartment next year.

I live in Argentina, here any HiFi driver costs about 2 times USA price, and sometimes even more. Its not easy for me to afford a HiFi setup, so I must be 100% sure and plan it to stay with same setup for many years.
In Argentina we do not have refund option, and it is not easy at all to listen a demo on several models.
My living is 4,3 x 3,3 metres, and I live at my own appartment, so the same living for a long time.
I have heavy curtains, and central carpet.
I already have a DENON X3000 (I could buy it same price USA). It is 95watts at 8ohms and 7.1 but I only care 5.1, so bi-amp is a nice opcion. 5.1 will be 60% music, and 40% movies.
I do care about sound quality, so I would prefere RTi line, instead TSi.
Will DENON X3000 make a good job with Polk RTi A7?? Bi-Amp??
Are Polk RTi A7 really too big for my living?? of course at high volume, but Im not interesting on listen them at the highest volume. So my idea is to have floor standers (some great ones really) & use them at moderate levels..
Thanks a lot..!!!
Fernando, I did not mean to hijack your thread at all. Here would be my humble advice to you: the Denon AVR you have would be FAR too weak for the RTI A7s (surprisingly tough to drive I'm finding out...) One thing I would consider since you have a small room and modest amp would be the tsi500. My brother runs tsi400 and they sound quite good with a modest AVR. They are very musical and are much more efficient than the RTI speakers. The tsi500 with four 6.5" woofers seems to be very underrated and would probably impress you (especially if you run a nice sub). -
I can say, I just upgraded to a NAD C375BEE (150 watts/side) with RTI A7s, the low end is outstanding.

Everything has it's limits. In Fernando's case, he has a small apartment and the Denon is plenty to keep him rockin'. Your room may be bigger, your placement not optimal, or associated gear and cables sub par. Any one of those can throw off the sound making you think you need more power. The Nad should be fine everything being equal, but we don't know all your parameters for the other things I mentioned.
Also, we all have different definitions of "loud". On a standard volume dial, once you start going higher than -10 your entering a danger zone. At 0 or in the + marks, your really tempting a call to CS for new tweeters. Listen for when the sound starts to sound congested/collapses....then back off that volume dial pronto...you've hit your limits and maybe then some. A good amp will allow you to play a tad higher and cleaner, but you still need to listen carefully at those higher volumes for any signs of stress.
The RTIA 7's are not that particularly hard to drive. Given the space you want to fill with sound of course.HT SYSTEM-

I already have both AV/R DENON X3000 (105wpc) and also RTI A7s (I bouth them finally about a month ago). Im still cant understand why 200-300wpc amp are recommended for RTI A7. With my denon I get excelent sound, at 90db my furniture and wood floor bibrates, I use to run it between 60db and 80db. Second day a neighbour asked me to drop down volume. I've never try it further than 90db, it seems that speakers would blow if so.
So... why 200-300wpc amp are recommended for RTI A7?? I does not seem a matter of power as 105wpc goes well. I believe that is a matter of distortion. Maybe it seems that further than 90db is too much for RTI A7s, but indeed it is too much for the amp. However since I use it between 60-80db its fine for me. -
Loudness does not equate to sound quality. Distortion also comes in many flavors, and what you are unaccustomed to hearing is an amp/receiver push a speaker well beyond its actual limits. While you may not hear any fragments or distortion in the common sense of the word, when it starts getting loud, the amp strains and causes the tonal balance to fall way out of whack. Soundstage collapses onto itself and everything sounds like its coming from one place. 99% of the world believes 'distortion' to be the only thing you can improve upon in audio, but it isn't.
I understand what you mean but not sure If I can recognize that in the sound. Since my room is 4x4metres, high volume is not an every day choise.
Indeed now Im also thinking on a vinyl tray, maybe a cheap one, due to I have about 50 vinyls from my grandparents, and there are some I would like to buy.If curiosity gets the better of you, start looking at some external amps. I'll give you an open warning that a journey like that might cost you much, much more than the amp itself.
Which way do you suggest for drop down the bass on RTi A7. I do love it most of the time, but when I want to hear music at very low volume, there seems to be much bass compare to mids and highs. -
Even in pure direct mode? How close are the speakers to the back wall?FernandoTorres wrote: »Which way do you suggest for drop down the bass on RTi A7.

In pure direct mode is better, but still occurs. The speakers are close to back wall, about 10 or 20 cm, but RTi A7 have an special rear port that allows that. -
