Infinity PR6512si (PR6512ISAM)

All Infinity Speakers offer superior sound top to bottom but the new Primus speakers feature the patented Plus One polypropylene woofers which feature more radiating cone area for increased output and edge-driven tweeters for better high-frequency dispersion.

Infinity Brand retains its spot as one of the world's top-selling car audio speakers by putting its speakers through a series of demanding reliability and environmental testing. Along with increased depth and detail, the Infinity Speakers provide clear vocals, horns, and strings and deliver deep bass. The PR6512IS Speakers offer true 4-ohm architecture with low impedance voice coils giving the amplifier room to deliver peak power. Speakers are individually voiced by some of the world's best transducer engineers to assure high-quality audio all at an affordable price.

Very Fast

The following review is for a previous version (PR6502is).

I ordered these speakers by telephone, as my computer was down. Sonic only had one set in stock at the closest warehouse, so they had to send them from the southern states to upstate New York. They expedited shipping at no extra charge and were at my place in about a week. I was impressed, as this was just before Christmas.

Great Sound!!

The following review is for a previous version (PR6502is).

After a short break-in period these speakers sound great. Drums sound like they are in the car with me. I matched these with primus components and have terrific full range sound. I recommend them to anyone looking for great midrange, a surprising low end, and crisp but not shrill highs. I love them! A steal in my opinion.

Very clean sound

The following review is for a previous version (PR6512IS).

I have always enjoyed the quality of infinity speakers. So when looking at the specs and price it was a no brainer on the purchase. Installed these in a 95 ford f250 with boom mat baffles and let me tell you after I adjusted the equalizer. The sound was clean and crisp. Would highly recommend these.

Wasn't very pleased

The following review is for a previous version (PR6502is).

I bought the speakers maybe 3 weeks ago and the right speaker has already gone out on me. With these being infinity speakers, I figured they would last some time with me rather than just 3 weeks.

Incredible!

The following review is for a previous version (PR6502is).

Bought these as a set to upgrade my entire Jeep speaker set...for under $200! They were installed in the rollbar and really boosted the mids and the highs rain down like a summer rain. Totally worth the money.
