P363 and Klipsch Sub-12

Just picked up a set of P363 for my new fronts. I have a Klipsch SUB-12 subwoofer. My receiver is a Yamaha RX-V775

I'm guessing I should set the speakers to small and the crossover at 60 or 80 ?

Any opinion on what is the better deal? (i am planning on buying one of there this week. Most like the infinity package)

I am buying used speakers through craigslist and have found a infinity 7.0 system with a receiver and a bic acoustech 7.0 system i am very interested in. Both are for 400.
infinity system includes beta 50s, primus 363s, and a beta center and 2 bookshelves.
Bic acoustech system includes pl89s and the matching center and 4 of the bipole sorrounds.

Opinions on which is better? I assume the acoustechs will be more bright and efficient because of their horns.

I also noticed the betas are 25 lbs more than the pl89s which makes me think they are better quality.

Please let me know your thoughts.

Beta 50s are really, really good speakers, better than the Primus by far. Use CMMD drivers. Designed by AVS contributor PLHart. I don't think it's a tossup.

I ordered these from Amazon, my current speakers are 5 x Michaura M55 bookshelves, which you can think of as Axiom clones (they were made by Axiom) which I got a long time ago and have been enjoying. So I will be using the P363 as fronts only, since the center channel is too much.

I'm hoping to notice a sound quality improvement even though the Michaura's were all the rage back then. There will be the first floorstanders I own, I'm slightly concerned if it makes any difference since I'll run them with a sub.

I have a pair of old JBL E20 and center that I've been living with for a long time. I haven't really been crazy about them. Note they are not the newer ES if it makes a difference.

Wondering if I would be happier with the P163 and PC351. Would this be a pretty good upgrade? These would be for some music, but mostly for movies.

Without you knowing alot of other details, but generally as far as quality of sound is this a step up?

Thanks

Hi splode, sorry can't answer if this will be an upgrade for you but I have enjoyed the Infinity Primus speakers (P363, PC351, P163).

Bought the last speaker in the store! Not sure if they're that popular and sold a lot or just had a few.

I also listened to a bunch of speakers while there and maybe my ears are getting useless or the room wasn't setup, because I could hardly tell the difference between them, except for the horn tweeter Klipsch which stood out, and all the Polks sounded sort of the same.

Thanks J, at these prices it's hard to pass up and there seems to be a lot of people happy with them. I have a sub, so don't think I need the 363s....don't have the room anyway.

Hey all.. I wanted to ask about placement for the speakers (362s and 163s). I've read that they do and do not require toe-in.. and I've read that they do and do not require space behind and to the sides. Therefore, I do not know what to believe. i will try experiment with placement a bit soon, but thought i would gain some insight while I'm away from home. Also, in a 5.1 setup is it possible to place the surrounds behind rather than on the sides? Right now I have them directly behind the couch but spread out and angled towards the center. I am considering putting them in a shelf on the wall behind the couch.

Thanks

Hi guys,.. another question I have relates specifically to my C350. I find that the audio for dialogue sounds a bit .. tinny/off/strange I don't know how to describe it properly. I've tried raising the levels for the center so that it stands out more, but it still has a strangeness to it. My current setup uses:

2x P362
1x C350
2x P163
NR807

The 362s are about 8 feet apart, 8 feet from the center of the couch and toed in a bit. The C350 is sitting inside a flexi-rack I built and is angled upwards slightly towards the middle of the couch (it sits just below the tv and receive sits on the shelf below that).

The shelf is 20" deep and is about 3" from the wall. I've pulled the c350 out about 1-2 inches from the shelf and tried putting some padding about 5 inches behind it. I can provide a photo if that helps.

I've tried adjusting the settings, running audyssey etc. For now, I've decided to just to set the speakers on the receiver by their distance, using an App on my phone to get the levels the same (though I made the center louder) and set the towers at full range, center at 80 and surrounds.. i think 80 as well.

EDIT please bear in mind that I currently am not running a sub, as I gave it away. My attempts at fixing with audyssey were after the sub was gone. It's a new flexi rack, as i previously had the c350 sitting up on top of another bench at the same level as the tv.

Ok I'm seeking advice because I don't think I have my speakers set up properly.

L/R. P363
C PC351
Pioneer elite vsx-53

I don't have a sub yet, I don't think I have it set up properly. To me it sounds between ok - good. Any advice?

Look at the Basic Speaker FAQ that is a sticky. Implement what you think is feasible. Then go out and listen to other users setups, ask questions, and have someone else, who has some expertise, hear your setup.

Primus PS212 popping cracking...new amp???

Hi,

Been A while but I need some help. My ps212 started poping one day and now it is impossible to use due to the noise. It's a popping screeching noise that happens WITH NO INPUTS PLUGGED IN...power cord only.

Can this be fixed? Do I have to replace the amp? Trash time?

Thanks for any input.

Mike

Most likely you have some caps that went bad. Easy fix if you know what you are doing. If not, it could potentially be expensive to fix. Possibly more than the sub is worth. You'll have to decide whether it's worth to fix it or not.

Thx for the reply. A little more research on my part found that there is some kind of reoccurring problem with some of the Primus subs and it is most likely caps since I still get sound.

I agree it doesn't make sense to spend money on repair or replace the amp for a sub that I paid 200-250 for. Bummer, I was going to sell it with a pair of 360's. 7.2 was over kill for my living room.

I'll put it in my "pending projects" pile.

Thx,
Mike

In my basement, I currently have the P163s up front with P153s for rears and a PC251 for a center powered by a Yamaha 375 with two sub-woofers (front BIC F-12 and rear Polk). It shakes the house and sounds great, but....I like the look of the P363s.


With my entry level Yamaha, would I notice any difference with the P363s over the P163s, or would the better upgrade be replacing the PC251 with the PC351?


On down the road I want to upgrade to a 7.2 so I wouldn't waste the leftover P153s or P163s if I get the $99 dollar P363s.

Which receiver are you using to drive the 363? I'm looking for a budget one, which one do you recommend?

The P363's are said to be quite difficult to drive so you'll need an uber high end receiver or amp that can put out a continuous 20WPC. So something in the say >$150+ range.

For those who couldn't tell, that's me being sarcastic. Most any non-HTiB, entry level receiver can power these speakers if you cross them over to a sub. If you run them full range then your listening levels and distance from the speakers (amongst other factors) will determine how much power you will need.

Being a noob to this, I have some more questions. So you meant I shouldn't turn it too loud if I don't have a sub yet? And if I have a sub, at what frequency do we crossover? Will the receiver do that automatically or we have to do it manually? Thanks

The sensitivity of the P363 is listed at 93dB @ 8 ohms. This means that it takes all of 1W to reach 93dB at 1m distance. For every 3db increase in volume it requires double the amount of power. For every doubling of distance from 1m you will lose about 6dB. THX reference SPL is 85dB with 20dB peaks. So to play at reference a speaker will need to be able play at 105dB. A properly calibrated theater should be playing at THX reference levels. This will give you an idea of how loud reference level SPLs is.

So what does all this information do for you? Going back to the P363 speakers sensitivity rating we can deduce that it requires all of 16W to achieve reference level sound at 1m, 32W at 2m and 64W at 4m. So if you truly listen at reference level and sit 4m from the speakers then you will need a receiver that can put out a clean 64W of power. Don't have a receiver that can put out 64W? Just lower the volume by 3dB and now you only need 32W to hit 102dB at 4m. This is not taking room gain into consideration.

Also keep in mind that this is if you run your speakers full range. If you run them small crossed over to a capable sub then power requirements dropped CONSIDERABLY. My speakers which are MUCH harder to drive than these P363s use a MEASURED 7W to reach 105dB at close to 3m when crossed over to a sub at 80Hz.

As for crossing over to a sub, this is set in your AVR. This setting is either set manually by you or automatically if the receiver has an auto-calibration process. The starting point is 80Hz, but you are free to raise or lower this frequency to suit your preferences.

Thanks duc135. I read all your posts in an old thread on slickdeals around June, lots of great information there. Now I'm leaning toward the AVR-1100W which I can get refurbished from accessories4less for $350. Hope it will be good.

I got my P363s today and what a difference they make over the P163s. Well worth the ...$99 spent for each speaker. The only down side was I am afraid to replace the P153s in the rear because of the weight difference between them and the P163s, so now I have spare P163s for a future 7.2. The little Yamaha 375 seems to power the speakers just fine and I noticed no difference in the heat output of the Yamaha.
