Overview
Dayton Audio 18" Ultimax Subwoofer and Cabinet Bundle 1,000 Watts
Build the ultimate subwoofer capable of moving over six liters of air with each stroke! Truly not for the faint of heart! CNC-machined subwoofer cabinet and the Dayton Audio UM18-22 18" subwoofer. The UM18-22 plays clean, low, fast, and LOUD. Designed to excel in either sealed or vented enclosures, it features an ultra-powerful triple stack of high-grade ferrite ceramic magnets for ultra-high force and exceptional control, plus dual aluminum shorting rings above and below the magnetic gap for minimized inductance, "faster"-sounding bass response, and perfect magnetic symmetry.
Features:
- 4.0 cubic foot CNC-cut cabinet made of 3/4" MDF panels with a 1-1/2" thick front baffle
- 18" driver with over 2" of total cone travel to move up to 6 liters of air
- Internal Bracing helps minimize panel resonance
- Internal dado joints for easy assembly
Customer Comments:
"Slams the lows, but still detailed and clean with the mid and high bass. Box is easy to assemble and cut accurately. Very pleased with the results. Especially considering the money spent." Rusty B ⋆⋆⋆⋆⋆
"This subwoofer is amazing! I ordered 2 of them and they blow my old Infinity 12inch and 15inch out of the water. The Infinities were ported and these of course are sealed, but the quality and depth are far superior. I'm using a Behringer NX-6000D to power them and it doesn't break a sweat!..." Gary M ⋆⋆⋆⋆⋆
