Infinity Primus P363 Floorstanding Loudspeaker Conclusion
It’s been a long time since I’ve had my hands on a pair of Infinity speakers. In fact, the last time was prior to Harman’s acquisition of the brand. Infinity is obviously a different company now. Their focus is more mainstream and budget conscious. This doesn’t mean that there isn’t some solid engineering behind these speakers. It’s far more challenging to make a budget product sound good than a costlier ones. That being said, I’d love to see what Harman could do with Infinity on a higher end line-up to bridge the price gap between Infinity and Revel.
Infinity seems to have taken a well-balanced approach in designing the Primus P363 speaker system. Sure I had some nits to pick, but the fact that these speakers were able to hit high SPL levels in my nearly 6,000 ft3 room without bottoming out or sounding completely shrill was truly amazing. I’ve had tower speakers costing $4k/pair that couldn’t play as loud. I felt the true strength in these speakers was in their fairly neutral and very fluid midrange response. It was obvious to me the midrange driver was the true workhorse and really shaped the overall sound of the system. I was impressed with the vocal clarity I was hearing coming from a single 4” driver. The P363’s produced great high frequency detail, though they were a bit sibilant at times depending on source material. The P363's sounded very consistent when I moved my head side to side thanks to the good driver integration and attention to off-axis performance Harman engineers paid when designing these speakers. At the retail price of $758/pair, there are certainly other options to consider. But, realizing the P363’s can usually be had for $400/pr on sale (sometimes even cheaper), they are truly a remarkable value. If you can catch the local deal Fry’s often offers for $200/pair for these babies, RUN out and get them even if they are for a remote system or office. There are currently no floorstanding speakers on the planet for that price that could compete in my opinion. Recommended!
The Score Card
The scoring below is based on each piece of equipment doing the duty it is designed for. The numbers are weighed heavily with respect to the individual cost of each unit, thus giving a rating roughly equal to:
Performance × Price Factor/Value = Rating

i read the review and from what i read, i had a pair of these for about a year..the weak link for this system is the tweeter. Though very efficient at high frequency it could use some upgrade down the road with a better unit. Any recommendations are appreciated!!!
