    Default Receiver/Speakers Confusion

    SO,

    Pretty much im a noob and have a pretty basic or close to no knowledge about this stuff but here's how it went down

    Ive bought a pair of Rti A9's along with a Denon AVR 2113 receiver
    .
    Receiver:
    http://www.denonasia.com/ap/Product/...uctId=AVR-2113

    And after some research....

    I know youre supposed to be matching the impedance of the speakers and receiver and ive done that (i think) but my question is, If the speakers are 500W and the receiver is producing 95 WPC, am i not using the speakers as efficiently as i could or to their fullest potiental??? ALSO, the most powerful receivers seem to provide 150WPC so if my speakers were 500 watts or above would i need an additional amp??? Is there a mathematical relationship that im missing somewhere???

    Im using this setup as a stereo setup for now, just to listen to music for the most part, but looking to upgrade into a surround system in the future

    If someone can just give me a short technical breifing that'd be awfully nice. Also, any other opinions/suggestions are welcome

    I know this thread might cause a lot of facepalms but in spite of googling my brain away i couldnt figure it out so thanks in advance!!!

    The 2113 puts out 95 watts per channel with two channels driven, if you hook up more speakers this output will go lower. The A9's like a lot of power. I would look at an amp of at least 200 watts per channel preferably more. The problem with the 2113 is it does not have preamplifier outputs that are required to add an external amplifier. The other problem with the 2113 if you drive it really loud you will drive it into clipping possibly damaging the speakers and/or the 2113. The short answer is you will need a new AVR and an amplifier.IMHO

    Thank you so much that helps a lot, however like i mentioned in my OP even the most high end receiver delivers 150WPC tops, so how do i set my system up???

    Any recommendations for a receiver/amp that would go along with the speakers??? Does that mean id have to buy a receiver with pre amp outputs and add an external amp???

    Also, how do i know if the receiver has the pre amp outputs? the spec sheets on these damn things barely make any sense???

    ^^^^Zane is correct

    Take the next level up Denon 2213 with pre-outs for an amp. You can run your system and when funds are available get an amp for the A9's and they will blossom. Enjoy the Receiver/speaker combo but don't over drive.

    I think a few of the people here would say that the TOTL Pioneer Elite series of AVR's would drive the A'9s ok. But for now get an AVR that has pre-amp outs, watch how hard you drive the speakers and get an external amplifier later.

    thanks txcoastal

    so according to the above, we dont have the 2213 available in asia but the 2313 is the next step above,

    Receiver:
    http://www.denonasia.com/ap/Product/...uctId=AVR-2313

    im hoping that will suffice, any suggestions on amps???

    also is there a way where the receiver does the job itself rather than having both the receiver and the amp funds not being an issue hypothetically??? just for my knowledge thats all because my question still remains, the high end receivers (at least what i know of) are limited to 150WPC max so im assuming an amp is necessary regardless.....correct me if im wrong

    Sorry typo...correct 2313 has the preouts

    Amp is necessary for better performance especially at higher volumes and larger spaces. You may find out out the receiver will suffice in your room and listening ranges.

    If your the type of person who critiques what your listening too, then an amp will probably give you better performance.

    What amp brands to you have access too?

    If you want to consolidate amp/receiver then Zane's recommendations for the Pioneer Elite series with D3 amp modules built in would be an upgrade over the Denon

    Yes, get an amp, many to choose from and if you have a used market yo can save some money that way too.

    Cool so the 2313 it is!!!
    umm im not familiar with amp manufacturers im assuming the receiver manufacturers do both in that regard but notable companies like Denon, Yamaha, Marantz are available, no used market unfortunatley... worst comes the worst ill just have it shipped and pay the heavy duties....i have a 14ftx21ft room which is pretty big IMO so the receiver should do just fine for now but im guessing the HT upgrade would definitely require more space. Just give me a few amp options and ill work my way around it i guess

    Thanks a lot for the input and help though really appreciate it, i owe yall big time if i wasn't in asia would definitely cover your bar tabs :)

    Heres another question though, you mentioned the amps run up to about 200 watts extra, couple that with the receiver that only gives me about 300 watts total....do i need to get something/provisions that add upto 500 watts or is that overkill???

    You will want an amp that will give you a minimum of 200 or 300 watts per channel to drive the A9's. then depending on the speakers you choose you can use the receiver to power the other channels. If you are going to be using this for home theater, Emotiva makes a pretty reasonably priced starter amp the XPA-2 that will give you 300 watts per channel and power the A9's pretty well, they also have an XPA-5 that would give you 200 watts per channel with five channels of amplification that would drive all of your speakers in a 5 speaker surround system. Look for them at Emotiva.com. There are also Adcom and Parasound amps available to name a few.

    ok so i went with the Denon 3312 which pumps out 125 WPC.....right now im only using the 2 floorstanders as a stereo system and i was reading about bi-amping through the receiver itself, would that be a good idea to get more power for the time being??? ive looked into your amp recommendations the only way i could get them is personally (they quoted me $750) just to get the amp shipped not to mention the heavy duties on the damn thing!!! so basically im gonna have to make the purchase personally and haul it myself on my next trip.

    I hope your not confusing biwiring w/ bi amping .Way 2 seperate things.Some speaker makers models come w/ 4 binding posts to bi-wire. A company like Vandersteen wants you to bi-wire if at all possible to get the best from the high tweets and low woofers. Most higher end speakers have this application w/jumpers in place already. Some say they hear immediate improvement and others don't bother.I have no such problem all my speakers only take 1 pair.

    The 500W rating is only a guideline of the peak undistorted power the speakers can absorb. The amplifier or receiver does not have to be rated at 500 watts. Most speakers are happy with as little as 10 watts, but may need much more to sound their best. Just follow the advice of those who are familiar with the speakers under consideration.
