Midrange speaker pair for car audio

The ALPHASONIK VCA658 is a pair of 6.5" midrange speakers built for automotive sound systems. Each unit handles 350 watts RMS and 1400 watts peak power at 8 ohms impedance. They suit owners upgrading factory locations or building custom door panels who need dedicated midrange output.

Paper cone and ferrite magnet construction

A paper cone combines with a 20 oz ferrite magnet to deliver 92 dB sensitivity across a 100 Hz to 8 kHz frequency response. The Thiele-Small parameters include Fs at 125 Hz, Qms at 11.653, Qes at 0.826 and Qts at 0.756, which define the driver's behaviour in a given enclosure volume.

Mounting depth and diameter constraints

The speakers require a mounting hole of 5.73" (146 mm) and a mounting depth of 2.72" (69 mm) per the highlights, while the supplier description lists overall depth at 3.62", mounting depth at 3.25", overall diameter at 8.27" and mounting diameter at 6.93". Installers must verify which set of dimensions matches their vehicle before purchase.

Questions about this item

Will the paper cone or 20 oz ferrite magnet need replacement after extended use?

The paper cone and 20 oz ferrite magnet are built for long-term operation; no scheduled replacement is required unless physical damage occurs.

At 350 W RMS and 92 dB sensitivity, what limits output first during sustained playback?

Thermal limits on the voice coil and the 100 Hz – 8 kHz frequency range define the practical ceiling before compression sets in.

How hot or loud does the 8-ohm driver get when run all day at high volume?

With 92 dB sensitivity and 8-ohm impedance, heat stays manageable and mechanical noise remains low within the rated 350 W RMS continuous power.
