Got them dialed in and they are sounding pretty good. A little bit warmer than the sony speakers they replaced with a recessed high-end. It seems as if the Sonys resolved high frequency detail just a hair better than these Infinitys, but its barely noticeable. However, the rest of the frequency range is superior on the Infinity. Bass notes are smoother (doesnt really reach much deeper though, but the Sony rocked an 8" woofer vs dual 5.25" on the Primus 250s) and mid-range is much clearer. With the mid-range on these speakers, lyrics are much more forward and dialogue is much more audible at lower volumes. They also seem to blend with my Def tech center better than the Sonys did as it is difficult for me to tell when sounds are coming from the fronts vs the center unless the sound is intentionally directional in nature.

And that brings me to the imaging and soundstage of these speakers. They are phenomenal in that category. Sounds are so much more expansive with these infinities. Sounds completely envelop the MLP even when in 2.0 stereo mode. And the soundstaging has a lot more depth to it with vocals being very forward incomparison to the Sonys which has a flatter soundstage. The imaging on the Sonys were decent and fairly precise, but these infinities put them to shame.

Thus far I am quite happy with the purchase, especially at the price I paid for them.

That's because they are designed to have relatively wide dispersion with consistent off-axis response. The wide dispersion means they are lighting up your side walls for greater envelopment and expansiveness. The consistency helps maintain the timbre of the speakers when the side wall reflections are combined with the direct sound from the speakers. I've always considered the Primus line a remarkable value.

Yes, it's a line that gets overlooked due to the low pricepoints, relatively uninspiring aesthetics and the abundance of availability. At least in their time.

Just curious, do you have an opinion of what might be considered examples of reasonable upgrades moving up from the Primus line? In other words, other great bang-for-buck speakers but perhaps a tier or two up in pricing? However you wish to define a pricing tier, i.e., $500 - $1000, $1000 - $3000, etc.

Those that also follow similar evidence-based design goals of wide dispersion and consistent off-axis response. I suppose the standard answer would be Revel, some PSB models, some KEF, etc.

As you mentioned, Revel would be the most obvious answer since they are designed along the same Harman principles. Kef would be another (even credit Toole in their reference white paper). Haven't heard PSB.

There are many, many excellent speaker brands out there. Way too many to list (or remember) but I've pretty much settled on older Infinity IL's and Mordaunt Short Aviano's. But also consider the JBL Studio 2 series, or the Studio 5's if you can find them.

https://www.jbl.com/studio-2-sale/

Or the Infinity Reference series.

https://www.infinityspeakers.com/home-speakers/

For those looking in the used market the Beta series can be found at very good prices these days. There's a pair of Beta 50's in beautiful cherry on Chicago's CL right now for $150/pr!

https://chicago.craigslist.org/chc/e...612312787.html

I'm also very fond of the older IL series. The IL 30's are the sleeper of the series. IL 60's ($$$) are one of the best consumer level speakers ever made...period.

But both the Beta and IL's are a bit softer and warmer then the Primus series which I feel is a bit bright on the top end.

I've been enjoying my IL60s for 14 years now, and they never cease to amaze me.

Question...so these are listed as 8ohms but reviews say they run more like 4ohms. I have a Denon 3300W that I can change the output from 8, 6, or 4 ohms. Should I adjust my AVR to 4 ohms?

I'm not sure if I'm allowed to post this, but sharing here in case any owners are looking for more speakers for their Primus since they're really hard to find anywhere.

I was gonna back your BST post over at ResetEra over the claims of these speakers' sound, but I didn't want to muddy up the thread. I have that exact same setup as you, with the addition of 2 P163s for my side surrounds. I couldn't begin to tell you if your pricing is fair, but I got those P163s back in April for $123.00 for the pair off eBay.


I've never been able to justify replacing these speakers with anything else, because I still find the sound quality to be excellent. Yeah, there's a whole lot out there that's better, but certainly not at the price point this line had before it was discontinued.

Word. You can rep me. I based it off what I’ve seen on eBay which is $100 for towers and $150 for the pc351 (even more rare than the towers). Feels pretty fair to me but we’ll see. Could be tough finding a buyer

Anyone driving them (or the newer 360 line) with the newer flagship receivers from Yamaha, Denon, or the like and noticed any differences in sound?

I am going to upgrade my speakers in the near future and was also wondering what some of you have upgraded to after Primus. I'm personally looking at Revel and sticking within the Harman line.

Sometimes I consider just sticking with the 360's I have now and just add a much better sub and a modern avr but the urge to upgrade is biting me.

Thanks,

Same here, still using them and they sound superb with a Denon receiver, but only so-so with Onkyo.
If you want to feel like you are getting new speakers, try replacing the receiver with a Denon.

I feel no real reason to upgrade yet, had my old 360's since around 2008.

Are infinity speakers considered “bright” compared to other brands...like the primus or reference product lines?

Yes, they are a bit bright. Less bright than Klipsch, but who isn't?



There's nothing wrong with bright speakers or warm speakers, it's really the listener's preference. Which camp do you fall under?

I have primus so I don’t mind the bright. I was just wondering how they compare to mid or high level Klipsch. I know the lower level reference series isn’t all that great.

Right now i had 4 P36x F&SideS,Pc350 P150 BackS and P140 FH with the pio SC 75. I thinking to upgrade slowly like the LCR first. Just scored Denon X4500H Frys deal. Then move P36x pair to surround back and the 4 bookshelves as height. And use Pc351 as voice of god. But still dont know what speaker to closely match with infinity primus.What others prefer most atmos or aura3d because voice of god setup wasnt in atmos.

I have a couple of Primus 363 floor speakers. Does anyone know if I would have have any issues using a center speaker from the newer reference series? Seems like there's a good deal today.

It will make you want to get new Reference series towers though.

Sorry for reviving this, but I can't find this information anywhere. Looking to get pc351 center channel on ebay to match my towers. Unfortunately I don't have the best setup for where to put it. My options are either to get a much smaller speaker, or put my 65 inch TV on top of it. Now it will fit dimensions wise, but how much weight can I comfortably put on top of it? My TV weighs 49 pounds with the stand

The cabinet is not made with sturdy materials nor is it braced internally I don't think. I would not risk setting a 50lb. TV on it. If it were me, I would mount the TV on the wall if possible. Second choice would be to buy a freestanding TV stand that replicates a wall mount and mount the TV high enough to fit the speaker underneath. If neither of those are an option I would go with option #3 which is to build a cheap 4 sided box just enough to fit the speaker in and set the TV on that. Last option if you don't have the tools or money would be go to your local home improvement store like Lowes or Home Depot and go where they throw their scrap wood. Find a piece of wood/plywood that is at least the same dimensions as the speaker and set that between the TV and speaker to distribute the weight to the ends instead of the middle.

Thanks so much! Unfortunately wall mount is not an option in my current apartment. And my TV stand isn't deep enough to fit in front of the TV, I think. There is a space under but it's meant for a cable box or DVD player so I only have 19x5 inches, which limits me. The space below that has a bit more height, but then I'd be giving my avr less air, and I think it would just be a bit too low for the speaker.

I couldn't get your first picture to load, but I was talking about a TV mount similar to the one in the link below. You can mount the TV to that and put the speaker below it if it fits. If not, go with option 3 or 4. I can't tell from the tiny thumbnail what your entertainment center looks like, but if the existing TV feet fit on the speaker then you can always build the box to cover the speaker and set everything on top of the entertainment center. Then set the TV on the box. That would be the safest way. The last option is to get a piece of scrap wood larger than the speaker and set it between the speaker and the TV to distribute the load to the edges of the speaker where it's strongest.
