Class-D amplification and an 18" driver.
Nothing can round out your sound system like a subwoofer—especially a subwoofer with an 18" woofer. The ALX-S18P brings out the low end notes in your music that you didn't even realize were there, and gives you the power to penetrate a large, packed dance floor with rich, full music.
Altec Lansing designed the ALX-S18P powered subwoofer to withstand demanding professional use, housing it in a robust, premium-grade, multilayer plywood enclosure.
The ALX-S18P features an integrated adjustable low-pass filter, phase control and output level control, so you can completely customize your sound in any setting.
Features
- 18" driver with 3" voice coil
- Robust, dense plywood enclosure
- Class-D amplifier with 800W RMS output
- Integrated low-pass filter, phase control
