INFINITY SPEAKERS PRIMUS 6512ISHI

Description

Technical Specifications

Features & Build

• Plus One™ woofer cone design: The woofer has more radiating surface area compared to many competitors of similar size. This is to improve output (especially in the lower frequencies) and improve sensitivity. my.infinityspeakers.com+1

• Hi-roll rubber surround: Helps in woofer excursion, improves durability, helps keep distortion lower when pushed. theWinkel+1

• True 4 ohm architecture: Even though the nominal impedance is ~2.7 ohms, the speaker design is built to allow for higher current draw, meaning the amplifier can deliver more power safely—this helps with peak performance. theWinkel+1

• Harman / Infinity reliability testing: The speakers are subjected to environmental stresses (temperature, vibration, UV, etc.) to ensure long-term reliability. my.infinityspeakers.com+1

What to Expect in Performance

Strengths

• Better than stock speakers: good clarity, especially in mids & highs. The tweeter is decent for vocals and treble.

• The lower frequency limit (~53 Hz) gives you reasonable punch — better for normal music listening though not deep sub-bass.

• Because of good RMS & peak ratings, paired with a decent amplifier or a good head unit, you can push these speakers to fairly loud levels without large distortion (if installation & power are done properly).

• Good build / durability — rubber surrounds, decent cones, reliability testing are pluses for long-term use.

Limitations / Trade-offs

• The low end is limited: below ~50 Hz, you won’t get strong output; for deep bass (EDM, bass lines, etc.) you will need a subwoofer.

• The impedance being lower (~2.7 ohm) means the amplifier or head-unit must be capable of handling lower impedance loads without overheating or distortion. Poor wiring or low quality amp might cause issues.

• Peak power numbers (165-220 W) are momentary – they don’t mean you can continuously drive at that power. Sustained use at high volume may lead to heating, distortion.

• Mounting depth / enclosure: depending on your car, the speakers might be constrained by door panel depth etc; if not mounted cleanly or sealed well, performance could suffer.
