Six-pack 6.5" woofers for PA replacement

This package contains six Goldwood Sound GW-206/4 woofers built for professional PA, DJ, karaoke and fixed-installation systems. Each driver handles 90 watts RMS and 180 watts maximum power at four ohms impedance. The 56 to 8000 Hz frequency response and 88 dB sensitivity suit live sound and studio monitoring alike. Stamped steel frames and poly-laminated cones with rolled foam surrounds complete the assembly.

Thermal and acoustic behaviour in normal use

Vented pole pieces and 20-ounce magnets with bumper plates help dissipate heat during typical playback levels. The 1.5-inch aluminum voice coils operate within their thermal limits at the rated 90 watts RMS, keeping distortion low. At 88 dB SPL the drivers deliver clear output without demanding excessive amplifier current. The four-ohm load is compatible with most professional power amplifiers.

Sustained-load performance

Under continuous high-level operation the vented pole pieces and bumper plates maintain voice-coil cooling over extended sets. The rolled foam surrounds and poly-laminated cones resist fatigue during prolonged excursion. Mounting depth of 3.01 inches and a 5.71-inch cutout allow secure installation in standard enclosures for reliable long-term service. Designed and engineered in the USA for consistent durability.

Questions about this item

How do I mount these 6.5" woofers and what hole size should I cut?

Cut a 5.71" hole for each driver; the mounting depth is 3.01" and the stamped steel frames use standard screw holes around the perimeter.

What part of the GW-206/4 is most likely to need replacement after extended use?

The rolled foam surrounds on the poly laminated cones will eventually dry out and crack, requiring a re-cone or driver swap.

At what power level does the 1.5" aluminum voice coil hit its thermal limit during long sessions?

Continuous RMS rating is 90 watts per woofer; sustained output above that will overheat the 1.5" voice coil before the 20 oz magnet structure saturates.
