Make sure the fronts of the speakers are at least flush with the edge of the bench (maybe even overhanging a little.) Otherwise you will have diffraction and/or first-reflections from the bench itself.

As with any speaker a sub will do wonder to your setup. The sub will create ambient bass versus direct bass from the speakers. I find the ambient bass to be more pleasing and not in your face.

For surround placement, they have "keyhole" mounting slots (if I remember correctly.)


Oh yeah, they are definitely for surround. I'll have to hook them up separate and give them a try.

Of course, I can't even give them a run as surrounds now- the wife has company over, and I've been banished to the computer room! The horror!!!!

Also, I purchased them from CC on-line, then picked them up at the store. When I got there, they said the in-store price was lower than the on-line price, so I got another $20 bucks off. Final verdict after I get the rebates back is $29.99 each. I almost feel guilty.


OK - I'm over the guilt now!

CC is discontinuing all Infinity, so they have some good deals on all of their stuff.

Interesting that they gave you the lower price and the rebate - I figured they had the in-store price at $50 because they didn't have the rebate. Wish I'd have known that, I picked up a pair yesterday. Oh well, my Primus system is now complete! New sub gets here next week...

When I am not at home, I often muse about speaker "upgrades". I see speakers at various price levels (in person or in pictures) and think "those would be nice". I tell myself "it would be great to have something even better than my Primus's".
Then I get home, put on some music and think "Better how? These are awesome!"

Nice Thread. For the record I currently have (You can tell I like closeouts - as do many here)

Front = Primus 150s ($40/ea CompUsa closeout)
Center = C25 ($45 CompUsa closeout)
Rear = Infinty US-1s ($15/ea CompUsa closeout)
Sub = Infinity SW-12 ($299 Circuit City closeout)
Sub2 = Mirage FRX-S8 ($40 used)
Receiver = Onkyo TXDS-989Ver2 ($450 Circuit City closeout)

Not a bad system for about $1k. Could have cost less if not for the receiver (I had the Onkyo LR552 for $99, but couldn't pass on the 989v2).

Am a happy HT owner of Primus 250's up front, C25 center, PS 12 sub (a powerhouse), 150's on the side. All driven by a Pioneer 1015 receiver. Have a couple of small Polks in the back for 7.1, soon to be replaced with Primus 140's.

Anybody thinking Primus are just "cheap" speakers should think again. A speaker like Insignia is a cheap speaker. The Primus line is much better quality, and only *inexpensive* because they are being discontinued.

I listened to some Ascends for a week trying to figure out why those little black box Ascends cost almost $400 (I bought them because of all the raves around here), but decided to send them back after comparing to Primus.

Think I might buy 2 more 150's for upstairs and pair them with the PS 8 sub woofer on an old receiver for music. Anybody have a PS 8? It is on closeout for $149 right now.

Just curious ... any special reasons for not going with 150s for back surround speakers?

Good point.

For 7 channel music the 150's would be much better. For 7.1 THX sound on movies I don't think it will matter too much. Only reason I am looking at 140's is the size of the speakers, the back wall of our HT is divided between a wet bar and closet, and the 140's fit better side by side.

Good enough reason to go with 140s

There are a lot of audio snobs who sneer at Primus because they don't think they cost enough to be "high-end". Making affordable speakers, however, was a conscious choice on Infinity's part. They are quite capable of making high end speakers that blow everyone else's away (and have, of course, done so in the past) but decided instead to distill all that knowledge and experience into speakers like Primus (and to stop making the ultra-expensive ones entirely.)
I have a PS8 in mint condition just sitting in a closet. I tried using it with my Primus 250's, but it didn't add much, in spite of being a nice sub (in my room, the 250's have plenty of bass for me.) It is for sale for $100 to anyone who will pick it up here in OKC. (Shipping isn't worth it.)

Primus 360 owners how do you have your speakers set? I have mine on "large" crossed-over at 80Hz and the C25 center and 150's set to "small". Is this the best way to set them up? I have a Pioneer 1015 and LFE is being handled by a Mirage S12 12" powered sub. Just curious as to how others have set their Primus 360's up.

I have them set to small (even 360s). Driven by Onkyo TX-SR504 and LFE goes to Infinity PS12.

Speakers set to "large" are not crossed-over at all. They receive the full-range signal.

For HT purposes, it is recommended to set all speakers as Small and let the sub handle all bass below the crossover setting, preferably 80hz or lower.

That is correct, however on some receivers there is an option, which (if set) will send bass info from front L/R channels to the sub. Not sure if all receivers have this option though. It is called "Double Bass" function on Onkyo 504 and it can be set only if your front speakers are set to large. Options for double bass are on or off.

With the double-bass, you may get more bass at certain frequencies but you will often have problems with cancellation as well, which may outweigh the benefit of the extra bass.

That's the reason, I have my front speakers (primus 360s) set to small and double bass set to off. I do use it occasionally for some of my 2 channel music though.

Ditto (except I have Advent H500 instead of primus 360's; very comparable sound quality though).

Well I meant to the C25 center and the 150's. But, thanks for pointing that out.

Looking to get speakers for a 7.1 system, and my Circuit City has some great prices on the Primus'. Unfortunately, their selection is limited, as are my funds. Can I build the whole thing with 150s, using the C250 as my center?

So long as you pair the 150s with a sub, you can use them all around and with the C250 center. For a sub, look at the Athena p4000, Bic H-100, and if you can get it for ~$200, maybe the Infinity PS-12.

150s are quite good, but if possible try to get 250s instead for front L/R speakers. They were available at CC for reasonable price. Vanns.com had 250s (store displays) for very attractive price (shipping included).

As for C250, I think it is from Beta series, so you might be better of with C25 as center. It is important that the front speakers (L/C/R) are tonally matched, and C25 is from primus line so all these will match.

How big is your room? If it is small the 150's would do an excellent job as long as you match them with a decent powered sub. If, on the other hand, it is rather large then the 250's or the 360's would be a better option. I bought my Primus speakers from Vanns and can't recommend them enough. My local cc did not have much of the Primus speakers left. So, I opted for Vanns. In fact, I also got my Pioneer 1015 and Mirage S12 from Vanns. Anyways, hope this helps. Good luck in your decision. Happy hunting!!!!

Does anyone know if multiple speakers can be purchased on the same transaction and still get the mail-in-rebates on each item? I'm trying to purchase 2-Infinity PRIMUS 250's and 2-Infinity PRIMUS 150's. Thanks.

I sure hope so, as I'm trying the same thing. I saw no indication that there was something wrong with it.

Perhaps it is better to call them and verify this. Rebate form on CC's website has this phone# listed.

Noticed this posted in one of my threads about Infinity:
https://www.avsforum.com/avs-vb/showt...=647998&page=4
I think the poster meant to put it here ....


-------------------------------------------

I'll be happy to give my views on the Infinity Primus series but can't contribute any further afterwards to the Owner's thread since I was not the Systems Design Engineer on the Primus.

-The Primus series was designed approximately four years ago by Bill D. who sat in the cubicle next to mine.

-In my estimation Bill is one of a handful of great loudspeaker design engineers. Bill has devised support software which complements the normal LEAP program we all used. For crossover design this software allows him to quickly come up with an extremely low parts count crossover which gives the best linear on-axis and (off-axis) power response envelope. It is this end result which allows the Primus series to be what I consider the absolute lowest price/highest performance ratio of any loudspeaker series in the Infinity line (if not the entire industry).

-for cost reasons the Primus line and all of its parts were made in China. The crossover components, both capacitors and inductors were lower quality implements that Bill was tasked to use for cost reasons. Same with the cabinet. The Chinese equivalent of 5/8 all around the wrap and back and I believe even on the front baffle. (Though the front may be ¾ (or 19mm).

-I would strongly suggest against ever trying to upgrade crossover parts in the quest for more performance. It isn't gonna happen. Plus loosening and tightening the screws a couple of times and you'll start to quickly wear out the threads cut into the brittle MDF that is used on these cabinets.

-the greatest chance for seeming unit-to-unit imbalance will come from the production variations of the tweeter. Again, low cost drives a wider plus or minus variation in each tweeter's response. (I bet this opens up a can of worms)

-In closing I'd recommend never trying to modify or mess with the Primus or any loudspeaker unit for that manner unless you really know what you're doing. Just play with set-up, positioning and pointing your speakers and read everything you can about how to fix your room acoustics. Because once that sound launches from the speaker cones they've already performed their electrical-to-mechanical-to-acoustic sound wave trick. From there the room takes over. And the further you are from your speakers the more influence the room will exert on the sound at your ears.

Good luck to all'
