i was just wonding if any one knows how far apart the front speakers can be , and my bass ports are in the back of the speackers how far should they be from the wall ? Also i wanted to know why my front speakers clip i have pioneer 1015tx witch is 120x2 and my towers are 150w. i cant tell if in better speakers or amp i really like to listin to my music in stereo. also the father i sit from my speakers the more bass i get but when i move up closer it sounds crapy. my room is a rectangle. shoud the speackers be placed next to the tv or at the ends of the room can loud music mess up my tv?


thank for all your input !

it really depends on your room size and what you like.

I would think atleast a min of 6ft apart is a good rule and angle them in to hit the sweet spot. the thing is if you move aroundthe sound is gonna change. its all about the sweet spot whether it be surround or stereo music.

pick a spot where you like to sit the most. decide an equal amount of space between the speakers depending on your room size and how you have your room and screen setup and angle the speakers toward you. a good rule is the speakers should be angled so they exactly meet head level at the same point to where you sit. eveyone has there own way and it really is something your gonna have to find out on your own. but moving around, the sound is gonna change. stick to your fav seating position.

Your receiver may not have enough power reserve if it's clipping. But it should have at 'normal' listening levels. What's the impedace of your speakers? Some amplifiers struggle with speaker loads of less than 6 ohms each.
In general, more power (reserve) especially current availability, is better if you like to play it loud, have a large room, and/or low impedance speakers. Check if your receiver has a switch on the back for impedance matching.

daleb is right. also, what is the min. power in for your speakers? and please don't take this wrong, if the THD of your amp is more than .0 it will add to the problem of clipping. proper impedence is crucial. as is proper phasing.

BTW: the 1015 is a sweet receiver and one of the last fairly current recievers in the pioneer line that had real quality parts and not elite!

that receiver should push your speakers no problem. I cannot imagine your $150 watt speakers are not 8ohms. have you clibrated your speakers and set the speaker levels accoringly. if they are set way low and your cranking it up could this be a problem.

if your speakers are 8ohm and with that very nice receiver you shouldnt be having any issues. is this a very large room ?

ya the 1015tx is a great amp! its not the amp its the towers


the speakes i have are 8ohms and they say 150 max but i was told that watts dont mean anything.also my amp is swichted to 8ohms . at
normal listing volume is fine. after a while i have relized that my proplem is my quest tower speakers they are very poorly made i think i need to get some athenas or jbl. altough my towers says 150 w is proply running at 70 max .

I suppose your speakers could be so inefficient, your amp is working overtime to get them to work. I don't really understand what is happening there. But what I do understand, is the SPL rating of speakers is of greater important than wattage rating.
You can forget the 'watt rating' of speakers once you get some quality ones hooked up.

took that advise and got a pair of jbl e90s ,proplem fixed

One thing this thread should highlight is the reasoning of using a subwoofer. With multiple bass sources there is the possibility of many locations in the room where the bass will be both attenuated as well as boosted depending on the frequency and the standing wave frequency(s) of the room. Multiple bass sources is problematic in most listening areas because the sound from one woofer can arrive out of phase with the sound from the other and diminish the bass at that point. Also the two waves could arrive in phase and boost a given frequency, thus causing a booming point.

The use of a single subwoofer eliminates the canceling issue of one speaker to the other and only leaves the standing wave issue to be resolved. Placement of the single subwoofer, phase and level controls will usually resolve these issues.

Multiple bass sources can be used sucessfully by placing multiple subwoofers near each seating area. The theory here is that since sound pressure level will logarithmically decrease with the distance from the source, the canceling waves from distant subwoofers will be considerably less than the source near the seating area and the canceling, or boosting, effect will be minimized.

Also it should be noted that what is presented applies to the low bass part of the spectrum. Basically frequencies below about 80Hz or so. This does not eliminate the need for woofers in the main speakers to handle the mid bass of 80-500 Hz or so.

If you are a person that likes to "feel" your bass, particularly in effects like explosions, then you might consider some tactile transducers on the seating areas. I find these to be very effective when crossed over at a very low frequency, like 40-50 Hz or so, so that the musical bass tends to not set them off. Mine require both very low frequency component plus very high sound level before they "shake" my seating area. Also if this is employed, it is good to have some way to control each seating area as women (and some men) tend to not like their booties shaken during a movie.

Why don't you read reviews of more popular brands? Lots of publications like Sound & Vision, Home Theater Magazine, Perfect Vision, etc. etc. do reviews contstantly including systems that are reasonbly priced. In fact, sometimes they seem to gloat in finding systems that give lots of bang for the buck. :)

Then go out and listen to them at retailers. I would not buy speakers without hearing them first. Trust your ears more than the specs.

Go out and get something of quality! Unless you just want to throw your money away.
