Please let me know if you have ever had an abrupt shutdown while cranking the Primus p360/362/363 speakers. I am not using the highest end AVR (Onkyo Tx-sr707), but so far I have not had any problems even when blasting the speakers.

Hi shadyJ, no issue here so far using a Denon 1909 (P363 fronts, PC351 center, P163 side surrounds and P363 as rear surrounds - no subwoofer yet) with the volume at -18 continuously.

I recently bought a Infinity PS312.
How much crossover should I leave behind the sub and the receiver?
ANd behind the sub, in PHASE Im set 0 or 180 ?

Hi vanSCHYNEYDER, if your receiver is handling the crossover set PS312 crossover knob to highest reading and/or toggle switch to LFE and phase to 0, volume level knob to about half and then run the receiver auto setup.

But I like Infinity's track record and their design looks solid.
Anyone find these harsh with brass instruments, cymbals, etc.?
I've always had soft dome for both music and movie rigs, as I tend to get fatigue as well, plus I enjoy a more "relaxed" sound for music. My current set up is movies only, so I bought an 11 channel set up blind, (8) 163's and (3) 351's when Newegg had the 163's for $50 shipping included. I am pretty happy with them, as at normal listening levels for movies they are very detailed. However, when showing off my system and running it reference level it is hard to find scenes that don't sound harsh. I even run audessy 32 and have a Sherbourn external amp, which helped a little but the harshness still comes through at loud levels. For the price you can't beat them. But if I was using them for movies and music I would probably buy a different pair just for music. Problem is there really is nothing that compares at this price point. Plus they are really built nice. What are you powering them with?

Hi all,

First of all, you should take a look at the one-day sale at Fry's.... if you are looking for a set of p363 of course

Two questions though:

1/ The place in my TV cabinet where I wanted to put my center in only 22' wide and the p351 is almost 24'. So, would a p251 still be a viable solution and not be too tiny with my p363 (and p163 and sub to be bought after that)? Or should I just get the p351 and hang it above the TV then?

2/ Fry's also has the JBL ES80 for just a tad more ($50 more).... should I get these instead? Are they better?

Thanks a lot!!

NOTE: my receiver is a Denon AVR-2312ci

BTW, I just picked up a Klipsch Reference RW-12d from Newegg... if you're looking for an affordable sub, this is apparently an awesome deal right now until end of day wink.gif

Metal, fabric, paper - the material that the driver is made from has nothing to do with how it sounds.

If your Infiniti's are sounding harsh at loud volumes, it's probably because you're pumping too much power into them. They are budget speakers - they are not designed for / capable of high SPL's. Music or movies, if you want to listen at high volumes, then you'll need better speakers.

Providing too little power of inferior quality to speakers is usually a bigger cause for distortion and harshness. Different tweeters most definitely will have different sound characteristics . Some people may not have the ear for it...but it's there.

There is no such thing as providing too little power. I think what you meant was pushing an amp with limited power beyond it's capabilities (thus generating distortion/clipping). In this example, it's the amplifier that is distorting, not the speaker, but damage to the speaker can occur.

In your example, this isn't what I was talking about because you said you're using a Sherbourn external amp - which likely has ample power and is not clipping/distorting. No, in your case, I said "too much power" because you may be exceeding the power limits of the speakers. Too much power into a speaker can cause the voice coils and/or crossovers to overheat, causing harshness/distortion. And with an inexpensive speaker like the Primus, the power limits are likely fairly modest - your Sherbourn is very likely capable of damaging them.

Finally, I didn't say different tweeters don't sound different. I said different materials don't affect the sound quality. In other words, metal tweeters aren't necessarily "harsh or bright sounding" and fabric tweeters are not necessarily "soft or smooth sounding" - it can go either way.

These inexpensive speakers drop to 4Ohm at certain frequencies. Yes, a serious amp can damage them like any other speakers. But, they are not crazy efficient like Klipsch speakers. The Primuses shine when given juice. Your ears will likely cry out before the speakers if they are given sufficient power.

The impedance curve for the Primus speakers looks no different from that of many other conventional two or three-way speakers. It's simply not unusual for an "8 ohm" speakers impedance to dip down below 4 ohms in small portions of the frequency band. Just look at the measurements for virtually every 8 ohm two or three-way conventional (dynamic driver) speaker on the market and you'll see the same thing. That's why manufacturers use the term "nominal impedance."

Hi all,

I finally bought a p351 (and used a bracket like that: http://www.amazon.com/gp/product/B00504G0U0/ref=oh_details_o01_s00_i00).

Now I ran Audissey on my Denon 2312ci, and it sets my front p363 to 'large' (which is fine since I have not hooked up my sub yet), and the center to 'small'. So far so good, except that the crossover for the center is set to 120Hz. My old Polk center (CS150) was detected at 60Hz.!

So is that a normal crossover value for the p351, or is it time to return it and get a new replacement?

Thanx!

NOTE: I just re-ran my Polk CS150 at the same exact location as the 351 and confirmed that it goes to 60Hz..... but now, my p351 indicates 150Hz crossover on my last run ;( Something wrong, no?

Hi BEZMan, my center is dialog is crisp and clear with crossover is set to 110Hz after auto setup.

Thanx a lot JChin!

I was just a bit concerned about Audissey registering 120Hz and the 150Hz on another run, whereas my smaller Polk is steady at 60Hz (same position). I was expecting the p351 to be in the same ballpark. The sound is great, but at 150Hz, I may get in trouble with my sub (which will probably cut out around 120-150Hz right)?

I am just worried that it may be indicative of a flaw in the unit I got. Is that really what this unit crossover at or do others here have had different results (which could indicate a defect with my unit)?

Thanx again,

Like you I don't have a sub connected yet. Will move one of the sub from the other room and rerun another auto setup this weekend. Hopefully I get the same result or a lower crossover reading.

I have not connected my sub yet. I will try this weekend as well. But I would have thought that it does not matter since readings should be independent anyways - should not matter if I had a sub or not, no?

The Primus line is designed so that you can mix and match as needed for your setup. That one advantage to it. So yes, go ahead and grab a 351. I did recently and I've been nothing but impressed. FYI, you'll want to make sure you have a sub since the 351 drops off at 80 hz or so.

Hi JChin,

You may want to double check yours as well. Looks like some other members report that the p351 drops off at around 80Hz, so 120-150Hz seems wrong. Looks like I may have to return it ;(

My Infinity Primus P163 Fronts & PC251 Center took a week or two to break in... at first they only registered around ~100Hz to 120Hz during Auto Setup. About a month later I ran auto setup again and got on the fronts @ 60Hz & center @ 80hz. Dunno exactly if it was break in period or maybe I just had the Audyssey Mic in a slightly different positions which showed the proper response?

Thanx for your response Shadowdane. Hopefully this is the case with mine as well - I will give them two weeks as well and recheck.. I have also emailed the Inifinity's Customer support to see what the think.

I bought from Amazon, so returning is not too complicated if I have too. Also, I am using a Yamaha setup mic for the moment on my Denon (the one I had wity my receiver was not working and I am in the RMA process with them), so that may also not help as well.

Again, thank you for sharing your numbers wiht me.

EDITED NOTE: I just read that, so looks like break-in may not help - looks like a debated subject - Audissey does not lie though: http://www.stereophile.com/content/breaking-new-speakers-4

The Yamaha microphone is highly likely to be a problem here. Yamaha doesn't use Audyssey and your Denon receiver is almost certainly not calibrated for its response.

Sorry, didn't mean to say that adding a subwoofer is going to change the center crossover. Atfer reading your post I was hoping my center channel crossover remain the same or lower. The center crossover result will depend on the speaker placement, frequency response in the room and mic placement.

Got a chance to run two auto setup and here are the result.

1st : front 60Hz, center 90Hz and surrounds 60Hz
2nd : front 40Hz, center 100Hz and surrounds 60Hz

Edit: you can borrow my Denon mic if you live in Dallas Tx area.

Right now, I have a

Denon AVR-1913
2x P363
PC-351


Planning on picking up two 163s soon, but debating whether to get the RW-12d or spend more money to get a PS312.
My receiver should be able to handle either of those subs, right?

Also, if I get the 163s, any idea how I can ceiling mount them?

I just got the whole system hooked up (still using the Yamaha setup mic unfortunately for now). Here are my readings:

- Front (p363): 40Hz
- Center (pc351): 110Hz
- Surround (p163): 60Hz
- Sub (Kilpsch rw-12d): had to turn the volume down to -20db

The sound is just great, with the sub not overpowering anything. My reading on the center dropped 10Hz, so I will just try again in a couple weeks.

Thanx again for your help!

Hi,

I was in the same boat and after much reading ended up buying the rw-12d from newegg for under $300 shipped (wait a bit they go on sale all the time). I am not expert and this is my first setup, but I was happily surprised that the sub "warms up" the music in concert without being boomy (kind of subtle at time but sharp - just turn it off and you will see it is missing - I hate boomy setups). In movies, it will blast away and makes you feel like the chopper is going to land on you wink.gif! I do not have experience with the PS312, but I got from other members that the Klipsch was the way to go.

So far so good - great system for the price for sure.

Can't wall mount frown.gif which has been my whole problem so far lol

edit: Just read it. How is this actually installed? does it just fit in-between the back wall and the TV itself? Would it still be okay if the TV isn't mounted and is just placed on a tv stand or does it require the TV being mounted on the tv stand? Thanks btw!!!

It attaches onto your TV (speaker platform rests on top) and then two screws with rubber tips secures it on the back and allows you to adjust the tilt. Very sturdy. My TV is on a stand (LG 55LHX). It is thin 55' TV and the stand works perfectly without putting strain on the TV or stand.

So Fry's has the P153s on sale now. Should I wait for the 163s to go on sale or just grab these? Grabbing these would also save me the big cost of finding a mounting brackets for the 163.

The mounting brackets on the P153 are just keyhole slots on the upper corners up each speaker. You can buy those for the P163 also.

Here is the manual for the P series speakers so you can see the bracket youself.

I have P363s for the front (along with a 351). The P153/163 would be in the back. I thought the 163s could not be mounted the standard way and I'd need something like this?
