Axiom Home Page Forums General Discussion Technical Questions ok, i need some help please!

ok i have a yamaha reciever, rated at 220 watts total, and two sets of speakers at 200 watts per speaker. i need to know what the relatioon is between the reciever and the speakers are. what do they mean? how do i make it all sound good? get a bigger better amp/reciever?

Ignore the speaker rating. It doesn't mean anything. If you turn up your amp to max volume and then play something with really loud peaks, you might hurt them. That's about it. Wattage on speaker ratings is just a caution, not a rating of what kind of amp you should have.

I'm guessing that a 220 watt total receiver is probably 44 watts per channel if it's a 5 channel receiver. In this case, you may want to upgrade. If it's a 2 channel receiver, 110 watts is cool. Of course, receiver manufacturers regularly inflate their wattage ratings...

its a 2 channel, rx 570 reciever, i have two sets of speakers a set csr-9;s and ar51's by technics,now the only thing is the speakers are great, bnut the reciever plus the speakers dont really sound to hot. i want loud music, (no prblem) but with alot of bass, the only thing is if i have it on the one channel, the csr-9s cant handle it too well, anywhere in the high volume range the woofers go into a constant shake/shudder. i dont know how to fix thi, i think i need a new cd changer too, the one i have when on, emits a buzzing sound through the speakers.

Is it a newer or older receiver? Is it stereo or multi-channel? What kind of speakers?

What is the impedance of the speakers? What is the efficiency of the speakers? What are the impedance ratings of the output of the Yamaha receiver?

What are you trying to achieve? Good quality sound? Loud listening levels? Both?

If you have very efficient speakers (ex. 95dB / 1W @ 1m) you don't need a lot of power from an amplifier to get loud sound. In the past, usually the best speakers typically had very poor efficiency ratings (86-88 db / W @1 m). Due to improvements in speaker technology there are a lot of newer "audiophile" speakers that are quite efficient (Axiom audio, for example). Any way, the less efficient a speaker is, the more power you need to drive it to obtain the same "loudness" level.

Receivers typically have inadequate power supplies to drive peak transients. For example, you may perceive this as "muddy" bass or somewhat distorted at high listening levels.

Some of the new receivers have nice processing sections and adding dedicated amplification to each channel can make an improvement in sound quality and how loud it can play.

Do you have a budget for which you are considering purchasing new equipment?

I'd say the problem is either with
a) a damaged receiver. possible, but unlikely.
b) you need new speakers.

>>anywhere in the high volume range the woofers go into a constant shake/shudder.

We should make sure that your amp is not clipping at high volume, since that can be bad for the speakers (and for any new speakers you get). Can you describe what happens at high volume a bit more (particularly if the sound changes) so we can be sure ?

If it's just the woofer cones flapping around because of very low frequency sound then no problem... although I think some of the older Yamaha receivers had a low frequency cutoff ("high pass") which to control woofer flap. It only cut off the frequencies below your normal bass notes so didn't noticeably affect the sound.

Don't write off the CD changer until you check to make sure the cable is good, and make sure the changer is plugged into the same AC outlet as the receiver at least for a trial run.

I second that: you probably need new speakers. Good news:
You are in the right place to look for them!

a sub wouldn't hurt either

thank you all for the replies, and the cd changer was really old anyway, upgraded, now it sounds ten thousand times better, and the clipping, or as i described it as the woffers going into a constant shudder, they do protrude a wooooooooing noises, not constant however, between two noises of similar sounds. and this only happens with my record player, not the cd changer either, a sub wouldnt hurt either. i would like to get a sub.

Sounds like a problem for Mr. Infrasonics Filter Man!

Do you have a high-pass, subsonic or infrasonic filter switch on your receiver?

Back in the day.... (I never told any of you guys this) I had an incredibly effective base for my Pioneer TT that I built. Picture a platform 2" high, 15" deep and 15" wide caulked on the interior and filled with Rhode Island's best beach sand.. There was no connected top, but just a 1/8" masonite board that was probably 14 1/4" square resting on top of the sand so it didn't touch anything else. Put 'yer TT on top, and you have a heavy, "dead", isolating platform.

Cleaned up the bass lines from any Ted Nugent album I threw at it!

Re: Cleaned up the bass lines from any Ted Nugent album I threw at it!
Terrible Ted and the ten fingers of doom! Anyone recommend a good compilation/greatest hits cd of the Nuge?

The ultimate Ted Nugent is a really good one to get.It's a two disc set with 16 songs on each disc.

Thanks Wid! I'll check it out...

Ah,..the 'ol "record player and NO rumble filter in the amp" routine....

Yup....lets throw those <20hz freqs at the speakers and see what'll they do!

A friend of mine finally got his hands on an old "FM" album (a Toronto group from the 80s -- the album was Con-Test for anyone local) and lent me his CD copy of the vinyl (not available in CD or we would own it already).

Fired it up on the M40s -- MAN did those little woofers flap around from the turntable rumble. Don't see that on a modern CD, even DSOTM.

this is all great infromation about the filter and such. got the cd changer all hooked up, sounds crisp clear to me. so how can i fix this little problem with my record player?

I think Mark's reccomendation that your turntable is being subject to vibrations from the loud audio. Possibly the low rumbling you are hearing is the feedback from the vibrations back into the phono cartridge? Get some long rca cables and move the turntable to another room. Play the source there, away from the loud audio and see if it is any better. If so then you can look into some sort of stabilizer for the turntable to rest on-

Good luck.
