6.5-inch PA Woofer for Live and Installed Sound

The Goldwood Sound GW-S650/4 is a 6.5-inch professional audio woofer rated at 85 watts RMS and 170 watts maximum. It presents a 4-ohm impedance and a 90 dB SPL sensitivity. A 1-inch aluminum voice coil and a 20-ounce magnet with bumper plate drive the silver injected poly cone with rubber surround. The stamped steel frame measures 7 inches overall.

Suits DJs, Karaoke and Fixed Installations.

This driver fits pro DJ, PA, karaoke, live sound and fixed-installation enclosures that need a 5.83-inch cutout and 2.94-inch mounting depth. It also works in studio monitor and home audio builds. Buyers who want extended low-frequency output below 35 Hz or higher power handling for large-scale reinforcement should look at larger-format woofers.

35 Hz to 5 kHz Coverage with 170-Watt Peak Headroom

The 35-to-5000 Hz frequency response handles vocals, guitars and keyboards comfortably in mid-sized venues. At 85 watts continuous the cone stays composed, while the 170-watt peak rating absorbs transient bursts without mechanical stress. Systems demanding full-range output down to 20 Hz or sustained SPL above 90 dB at distance will exceed this driver’s usable range.

Questions about this item

What amplifier power rating matches the 85 W RMS / 170 W max handling of the GW-S650/4?

Choose an amp that delivers roughly 85 W RMS per channel into 4 Ω so the woofer runs within its continuous rating while still having headroom for peaks.

Can the 4 Ω impedance and 90 dB SPL work with an older 8 Ω-rated PA head?

Most legacy heads will drive the 4 Ω load safely, but expect up to 3 dB more output and verify the amp is rated for 4 Ω operation before connecting.

How do I confirm the 35 – 5000 Hz response is performing correctly after installation?

Play a swept sine from 35 Hz to 5 kHz and listen for even output with no rattles; the cone should move cleanly through the full range.
