Overview

Our take on the Infinity Primus PR6502is

Vehicle manufacturers don't put much thought into stock stereo systems, and it shows. Uninspired vocals, muddy cymbals, and flabby bass are dead giveaways that you've got stock speakers. Install a set of Infinity's Primus PR6502is 6-3/4" speakers in your car and you'll notice a world of difference. Lifelike vocals, crisp cymbals, and well-defined bass await you, and cruising around town will be more enjoyable as you get pulled into your favorite tunes.

Built with home audio know-how

Infinity used technology from their popular Primus home speakers to design car speakers that offer strong performance without breaking the bank. A 3/4" edge-driven, textile dome tweeter broadcasts smooth high frequencies while the oversized, Plus One+ polypropylene woofer creates solid bass. The speakers' 3-ohm impedance safely draws extra power out of your factory radio, aftermarket stereo, or an external amplifier, so you'll get a little more punch from your system. Grilles are included.

Good sound.

Features

Plus One Woofer Cones: The Plus One speaker cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.

3-ohm Voice Coil: The Primus Series speakers feature 3-ohm voice coils to compensate for the high in-line resistance of small gauge factory wiring and extract every watt from the factory receiver, increasing overall system output and efficiency (relative to 4-ohm speakers). The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers capable of powering a 2-ohm load.

Power Handling: Although Infinity lists the continuous average RMS power handling as 70 watts, they also list the recommended power range as 5-125 watts RMS. We've opted to list the more conservative 70 watt RMS figure on the specifications page.

Mounting: Infinity markets these speakers as 6-1/2"; they will fit in standard 6-1/2" speaker openings (approximately 5" diameter), but they do not use the standard 6-1/2" speaker bolt pattern. In order to install them in standard 6-1/2" applications you must drill new screw holes. The speakers are easily installed in many standard 4-hole 6-3/4" applications with no modification.

I would not recommend these speakers on any car. They don not sound good with songs that have a lot of bass. I would not buy them again They are probably not as good as the base speaker in your F10 (5 series). [ David  May 21, 2017 ]
These Thiele Small parameters are a bit advanced for a Q/A place like this because these work together with others to help you design the best box for a woofer and gauge how well it will perform. The main ones to consider are Fs: resonate frequency of the speaker, Vas: the volume of air equal to the compliance (stiffness) of the speaker, and Qts: the total amount of mechanical and electrical loos of the speaker at the Fs. These help you determine how big to make the box, the shape of the box(helps determine the tuning frequency of the box), and gauge how loud it will play (how much power you need to run it for the desired volume level). There is calculators out there to help you design the best box for the woofer. Any further questions on this should be handled through an advisor that you can reach on 1-800-324-9695.

For their size, these are incredible speakers. They are accurate and crisp. Use lots of batting in your enclosure as they can be a little harsh. I installed them in my travel trailer and they fill it up with music. [ RICHARD A  Dec 20, 2015 ]
Overall, a decent speaker. Quality of sound is pretty good when compared to stock. [ Michael  Dec 19, 2015 ]

Sorry for the late reply. The reference are infinity's entry speaker level. Then it's the primus and then it's top which is kappa [ vietstyle888  Sep 03, 2014 ]
I never heard the other but these sound great!!!! [ KURTIS  Mar 19, 2014 ]
I personally own 3 pairs of the infinity primus and I think these are the best but I've never heard the other ones. [ ALFONZO  Mar 18, 2014 ]
The Primus have good sound and quality especially if given the right equiptment such as an amp and after market radio system. Overall all i feel there an excellent set of speakers. [ PATRIC R  Mar 18, 2014 ]
