Features & Build
-
Polypropylene Woofer Cone: Good balance of light weight + rigidity; helps with responsiveness and durability. infinity-caraudio.com.au
-
PEI Balanced Dome Tweeter: For extended highs and clarity; helps with vocals, cymbals, strings etc. infinity-caraudio.com.au
-
External Crossovers: Because it’s a component system, the crossovers are external (not built into the woofer), which helps with better routing of signals (woofer / tweeter) and typically cleaner audio. infinity-caraudio.com.au
-
Reliability Testing: The Alpha series is said to undergo environmental and durability testing (vibration, temperature extremes, UV etc.). infinity-caraudio.com.au
What to Expect in Real-World Performance
Strengths
-
Sound clarity: The separate tweeter + crossover means you can expect cleaner highs and better separation than most basic single-unit speakers (coaxials).
-
Good mid / bass from woofer: With a 55 Hz lower limit, you’ll get decent punch for mid-bass in many types of music (rock, pop, acoustic etc.). It won’t reach deep sub-bass, but for its size it’s solid.
-
Works well with modest power: 45 W RMS is not huge, but it’s enough to get good output in many cars if matched with a decent head unit or small amplifier. Sensitivity 91 dB helps reduce how much power you need.
-
Flexibility in installation: Because it’s component, you can place the tweeter separately (e.g. high on dash or A-pillar) for better imaging.
Limitations / Trade-offs
-
Limited deep bass: Below ~50 Hz or so, output will drop off; for very bass-heavy music, you’ll want a dedicated subwoofer.
-
Power ceiling: While 315 W peak sounds high, that’s for brief peaks. Sustained high volume will require clean power and good build. If you push it too far with inadequate amplifier or power supply, distortion or damage could occur.
-
Need proper installation: Mounting the tweeter, routing the crossover, making sure wiring is clean and correct polarity, ensuring secure mounting and minimizing vibration will be important to get the best performance. Poor installation can degrade output significantly.
-
Space: You need enough space in your door or wherever you mount the woofer; cut-out size, mounting depth etc may be constraints in some cars.
