Introduction

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. 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. The P363’s produced great high frequency detail, fluidic midrange and punchy bass response. They sounded very consistent when I moved my head side to side thanks to good driver integration and attention to off-axis performance. 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. What they lack in aesthetics, they make up for in sound quality and value. Recommended!

hi

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!!!

I've got a Technics SL-1900 with a Shure M44-7 cart. I bought this cart. 6 or so years ago for its low-end response to be perfectly honest. I've have since grown out of my need for this type of cart and am looking to find a lower-output/warm cart. to put on here. Its served me very well though and I've no complaints.

Actually if anyone wants to weigh in, my TT is in dire need of being serviced in the rising/lowering platform for the arm. I think it uses some sort of viscous fluid to apply friction to this motion and I need to replace it but I'm not sure how. If anyone has any tips it would be highly appreciated.


For those who are interested, this is an older video (with the old speakers) of my equipment. And I don't want to hear about the TT placement because it was temporary for the video :P

You should PM TLSguy about the TT. He can almost certainly point you in the right direction.

I thought it looked like a Technics, but smaller. I run the SL-1210 with Shure M97xE

Well this is long overdue. Sorry for the poor cable management but here are the new speakers! I absolutely love them.
