Four 5.25" shielded woofers for PA builds

This set contains four Goldwood Sound GW-5028/S woofers built for professional audio enclosures. Each driver handles 70 watts RMS and 130 watts maximum power at 8 ohms impedance. The frequency response spans 62 to 9000 Hz with 85 dB sensitivity. Shielded construction prevents magnetic interference with nearby equipment.

Shielded frames and poly mica cones change

Full magnetic shielding allows the woofers to sit close to CRT displays or sensitive electronics without distortion. Poly mica cones with rubber surrounds resist humidity and mechanical fatigue in touring or fixed installs. Stamped steel frames and 16 oz magnets keep the structure rigid at high output. The one-inch aluminum voice coils dissipate heat during extended sets.

Suits installers needing four matched drivers

The 4.41-inch cutout and 2.68-inch mounting depth fit many standard PA cabinets. Buyers who want more storage, integrated amplification, wireless connectivity or a single larger driver should look at something else. The 5.43-inch overall diameter may not suit enclosures designed for smaller chassis. Four units arrive ready for parallel or series wiring.

Questions about this item

How often will the rubber surrounds on these 5.25" woofers need replacement?

The rubber surrounds are built into each woofer; they typically last many years under normal indoor use and are not a scheduled maintenance item.

What power limit is reached first when running these woofers continuously at high volume?

Each woofer handles 70 watts RMS; sustained operation above that level will hit the thermal limit of the 1-inch aluminum voice coil before the 130-watt peak rating.

How much heat do the 16-ounce magnets and steel frames produce during all-day operation?

The 16-ounce magnets and stamped steel frames dissipate heat passively; at the rated 85 dB SPL and 70 watts RMS they stay warm but not hot enough to require active cooling.
