INFINITY SPEAKERS PRIMUS 6510CSHI

Description

Key Specifications

Here are the published / aggregated specs from Infinity + verified retailers:

Features & Build

• Plus One+ Woofers: The woofer cones are designed with more radiating area compared to many in the same size. The idea is more surface area = better bass / more efficient output. my.infinityspeakers.com+1

• Edge-Driven Tweeters: The tweeter sits near the edge of the hoop/basket structure so high frequency dispersion tends to be a bit wider, smoother. Also helps reduce harshness in highs at loud volume. Crutchfield+1

• True “4-ohm architecture”: Even though the speaker’s nominal impedance is ~2.7 ohms, the design is such that it’s supposed to allow extra power draw (from an amplifier or even a decent head unit) without overheating or distortion. The trade-off is that your amplifier or head unit must be able to safely drive lower impedance. infinity-caraudio.com.au+1

• Durability / Reliability: Built to meet certain automotive reliability standards (temperature extremes, vibration, UV etc.). my.infinityspeakers.com+1

What to Expect in Real-World Use

Strengths

• Better clarity and separation: having separate tweeters + crossovers allows placement and alignment that can improve imaging and crispness of highs.

• Strong mid-bass: Given the 6½″ woofer plus high sensitivity, you will get punchy mids and decent bass for many kinds of music (rock, pop, etc.).

• Works well with both head units and amplifiers: Because of its RMS power rating (80 W), it’s not super-high end but certainly an upgrade over stock speaker setups. If you feed it decent power, performance improves.

• Good fit for many cars: The woofer depth is moderate (~52 mm), which helps in many factory speaker locations.

Limitations / Things to Be Mindful Of

• The low-end (below ~50-60 Hz) will be limited: the system’s usable lower frequency limit is ~53 Hz according to specs; for deep bass (sub-heavy tracks) you’ll likely want a subwoofer.

• Lower impedance (2.7 ohms) yields more current draw; a weak amplifier or head unit could struggle or distort if pushed too much. Also wiring quality and power/ground connections become more important.

• Peak power handling claims (240-320 W) are short bursts; sustained high output will heat things, and performance (clarity) might drop if amplifier / source is clipping.

• Installation: because it’s a component set, you need to mount tweeters appropriately, place crossovers, do wiring cleanly etc., which takes more effort than coaxials.

Comparison / Variants

• There is a variant named PR6510CS (without the “HI”) in some markets; very similar specs (80 W RMS, 240 W peak, same sensitivity etc.). my.infinityspeakers.com+2Crutchfield+2

• The “HI” suffix may imply regionally marketed or packaged differently (maybe includes different accessories, grille, or matches regional preferences). Some sellers list the peak power as 320 W for the “HI” version. autoclint+2Car Concepts Shop+2
