Overview

PRV Audio RS8-SUBD4 RS Series 8" Subwoofer DVC 4x4 Ohm

PRV Audio RS8-SUBD4 RS Series 8" Subwoofer DVC 4x4 Ohm

For 15 years, PRV Audio has designed and marketed professional live audio speakers, and is proud to launch the RS Series, which introduces new subwoofers, amplifiers, and car speakers built to deliver high-fidelity sound and performance specifically for the car audio market.

Compact yet powerful, the 8″ RS8-SUB car subwoofer delivers impactful bass. Engineered with performance in mind, it is an ideal solution for compact pickup trucks or any vehicle where you want to add a subwoofer without giving up trunk space.

  • Optimized for use in compact enclosures, ideal for under-seat or behind-seat truck boxes
  • 4-layer high-temperature copper voice coil capable of handling 500 watts RMS program power for high acoustic output
  • High roll U surround with 14.5 mm Xmax for low bass reproduction without distortion
  • Side-forced cooling system with vented back plate design for improved heat dissipation
  • Dual 4 Ohm design allows easy parallel connection of two subs to 1 ohm

This subwoofer is built with a heavy-duty magnet motor that boosts both output and low-end response, giving it the ability to handle more power while producing deeper, more impactful bass. The dual magnet structure provides an impressive 14.5 mm Xmax, offering excursion levels comparable to much larger subwoofers.

This powerful 8″ subwoofer can achieve 1.3″ peak-to-peak excursion before damage, enabling deep and impactful low frequency bass.

Recommended Amplifier configurations:

The LPF on amplifiers should be set between 80 – 100 Hz when using musical power up to 500 Watts RMS, Subsonic filters should be set according to music style, this will help to avoid subwoofer damage from excess excursion caused by ultra low frequencies.

Take your time and break them in! A brand-new sub is always a little stiff but after break-in, the subwoofer soft parts will stretch out! This means with less power you will create the same output with more extended low bass tones

Recommended Custom Enclosures: Inside measurements based with 3/4″ wood material.

*Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range.
**Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to avoid a clean signal without clipping or saturation.
***Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
