Infinity Primus Owner's Thread - Page 119

I leave that to your ingenuity. The lazy way to do it is to just stack a couple of end tables on top of each other - which is what I have done so that the base of the speaker is up about 36" off of the floor.

Primus owner here with a question about using towers as surrounds and raising them. I currently have 362s as fronts a 350 as center and 252 as surrounds with an old acoustimass 3 for rear surrounds until the 163s go on sale again. The 252 are in the floor and I do notice that my pio mcacc calibration sets them higher than anything else. Will raising them make a difference in calibration or just improve imaging? What is the benefit or reasoning for raising them? I use them for movies games and extended stereo for music.

Raising the surrounds makes them less directional, meaning that the speakers do not call attention to themselves in PLIIX. Aside from movie mixes, PLIIX gives the illusion of ambiance especially in audio music CDs. In an Audyssey calibration, it will make a difference - can't say anything about your calibration because I don't know anything about it.

One follow up question...

How high should the speakers be raised (using P363s as surround and rear speakers)?

As high as you can get them up. Mine are 36" off the floor. You have to be careful in that you will need to play with toe-in with the back surrounds. Assuming that you have a sofa and not a multi-row viewing area, place the immediate surrounds immediately lateral to the seating area, not behind.

So the bottom of the P363 should be around 36' above ground? Just checking because generally I have seen surround speakers much higher like the top edge of the speaker just around a foot or less below the ceiling.

I didn't understand the comment about need to play toe-in with the surround. Could you please elaborate?

Thx a lot.

If you can get them higher than 36" than do it. Mine are 15" from the ceiling, but I am running height speakers that are mounted and inverted with the tweeter on the bottom. The vertical distance between the surrounds and heights of the tweeters is 4" vertically.

As to toe-in and all of your speakers (including the fronts), you should probably play around with it and decide what sounds the best to you in your particular setup in terms of the viewing area and main listening position. The most difficult thing to achieve in a home theater is setting it up for music, as in CDs, and create a seamless sound stage that stretches to the width of the room with the surrounds providing room ambiance. Most of this is dependent upon the room and what is sitting inside of that room, plus utilizing room superior correction such as Audyssey XT32. There are few hard and fast rules. And even some of those may have to be bent. A lot of this is dependent upon how much interest one has in audio reproduction because there can be continual tweaking that may never end.

In case anyone is wondering the P163BK is available at Tigerdirect for 85 dollars.

Sadly No such deal @ tigerdirect.ca sucks

It's also 85 on Amazon.

if you have Fry's, you might want to wait. i got mine a few weeks ago for $60 each

Crutchfield has them on sale too..but screw them.
I called on Monday to order a pair plus a pair of pinpoint mounts. I just wanted them to hold them 2 days before shipping since I was out of town and would be getting back tomorrow.
Now they have it all screwed up the brackets are back order and they are holding the whole f'n order. ETA is end of the month now f me

Hello! I was thinking about those 2 speaker configurations too... I too am really leaning towards 6 P363s, but with a different receiver. Would you really need to get the P363s off the floor though?

Can anybody elaborate?

I can see how you would want to elevate the rear channels, but it's not absolutely necessary.

P143, P153 and P163 on sale at Fry's today thru next Thursday.

Do you have to show up to the store to get the discount or can they be shipped? Because I'm far away from Fry's.

Also how do you get the savings? I don't see a promo code. They are currently listed 139.99 for one.

So I have to eat crow here, they had a power outage and my order emails were not accurate. The order was delayed but everything is in stock and I should get them by monday or tuesday.
Still don't know why they cant hold an order but oh well.

Of course, no one has to do anything. It is just a suggestion. If the P363s as surrounds are sitting on the floor, the tweeters are at ear level, approximately, and are very directional, meaning that you will immediately sense in what direction the sound is coming from. That's fine for film, whether it be 5.1 or 7.1, but not ideal for music CDs, matrixed with PLIIX. To hear what the difference is, just put the P363s on some card board boxes and compare it to when they are sitting on the floor. If you want a sense of height, say like the helicopter flying over in the opening of Cliffhanger BR, you won't much of that with them sitting on the floor.

Does the P143 have just one keyhole slot like my Infinity Entra Point 5s??? They say this can be mounted to a stud but according to the manual, there's 2 keyhole slot which would necessitate using drywall anchors. Also, is the slot long enough, like in the Entra Point 5s, so that if they get bumped or from vibration, will not come off of the keyhole slot. The manual makes the keyhole slots look short and the entry hole look way to large to secure them properly so they can't come off.

Thanks for the help. I currently have speakers on stands and am baby proofing the living room. The large surround book shelf speakers won't mount to a wall but the rear surround Entra Point 5s will. So I just have to replace the surround speakers.

I called Frys and they said deal is only available in person and won't show up in the online price...

I just bought an onkyo tx nr 717 receiver and have a room that is 23' x 23' and 10 foot ceilings. Would the p363s be overkill for my setup and could my receiver drive them adequately? If so, what would be a good sub, rear, and center channel pairing? Thx.

The trouble I had, was I ordered 4 P163's assuming they did indeed have built in wall mounts, as the description says. Upon arrival and inspection, there are no such wall mounts built into the P163's case.

I am returning them, and debating on whether to get the P153's instead, or go with another speaker.

On the other hand, I will likely need to be able to rotate them, so I'm debating finding a pivoting mount also...

this wall mount has been recommended a few times that i've seen

http://www.amazon.com/Pinpoint-AM-40B-Clamping-Bookshelf-Speaker/dp/B002UV03MW/ref=sr_1_4?ie=UTF8&qid=1363004791&sr=8-4&keywords=speaker+wall+mount

You'll have no problem driving the tower speakers with that receiver, and for a room of that size, I think the towers are a good choice.

For the center, I would get the Primus 350 or 351. For me, the 351 center channel was the reason I went with the Primus line. It's big, but it also is responsible for a huge amount of the sound in movies.

For sides and rears, I have Primus 162s and 163s (same, just cosmetic differences). I like having the 6.5" woofer, but the 153 would be fine as well. I would only go down to the 143 if you needed to for size constraints. The 143 isn't strong below 100, and I prefer crossing over to my sub at 80 hz.

As far as the sub goes, that's a whole separate discussion. You have a large room, and the decision would really come down to the budget.

Well then I'm out of luck then. I don't mind paying 84.99 for one. Much better than 139.99.

Currently going for $85 on Amazon...

I just picked up a set of the P163s from that Fry's ad to use with my computer through a marantz receiver. They are replacing an older, smaller set of actual near-field studio monitors from Alesis (these are obviously built for a different use!).

I just have one little issue - Cabinet structure resonance. Obviously, these are $85/ea speakers so I can't really compare them to my sonus faber bookshelves and the old studio monitors... but there is some music that causes odd vibrations. Specifically some strong acoustic guitar plucks and deeper vocals can be muddy. Check out the Alison Krauss song, Paper Airplane for an example. I've read that people have modified the cabinets to reduce this, but... WHERE are the threads that talk about these mods?

I'm also going to be working on some new speaker stands which will probably do better than the Mousepads that I'm using for isolation now.

annihilatorg,

Are the P163 good?


And does anyone have speaker stands that they recommend? Currently I'm looking at these....
