Infinity P363 Introduction
Infinity has been making speakers since 1968 and is probably one of the most recognized names in the industry, especially since Harman acquired the brand. While their core business these days is car audio, they were once an esoteric high end home audio loudspeaker manufacturer. These days, Harman has refocused the brand more mainstream for big box stores and internet sales channels leaving Revel to fill in the gap for those discriminating audiophiles wanting more upscale products. The Primus series is currently the top of the line offering from Infinity. In fact, this line of product is a favorite among our forum community, as many have claimed them to be a superb value. You can check out Tom Andry's review of thefor his thoughts. I was curious to see how their flagship P363 tower speaker would perform so I requested a review set. The Infinity Primus P363 is a 3-way floorstanding speaker featuring dual 6.5” MMD woofers, a dedicated 4” MMD midrange and a ¾” MMD dome tweeter.
Let’s take a tour of these speakers to see if they live up to the hype and benefit from the vast R&D Harman resources to make them a solid product offering from a brand that has built a reputation of quality for over 40 years.

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!!!
