6.5" 125W RMS 8 Ohm Low Mid Frequency Loudspeaker Sealed Back APMB-6SB-E

This Listing Includes:

  • (1) APMB-6SB-E 6.5 inch Low Mid Frequency Loudspeaker

The APMB-6SB-E is a 6.5 inch low mid-range loudspeaker engineered for powerful midbass performance, clean vocal reproduction, and reliable operation in demanding audio systems. Designed as part of the Low Mid-Range Series, this speaker uses a cloth edge surround to enhance low-frequency response while maintaining clarity across the midrange.

Its sealed back steel basket design isolates the rear wave, protecting the speaker from external interference and eliminating the need for additional enclosure volume. This makes it ideal for tight installations, door panels, pro audio builds, and vehicle applications where space and control matter.

At the core is a 1.5 inch high-temperature KSV voice coil with improved ventilation, delivering consistent performance and durability under continuous power. With 125 watts RMS handling, 250 watts peak power, and high sensitivity, the APMB-6SB-E delivers strong output with excellent efficiency.

Easy-mount installation points, a rigid steel basket, and a 20 oz ferrite magnet complete a speaker built for performance, reliability, and clean sound reproduction.
