The BL Series fills the gap between the all out SPL monster and a solid daily driver. Featuring a solid pole piece and standard double stack motor structure as the foundation for a truly tough subwoofer, you can choose from a variety of options to custom tailor the sub for your exact application. With the addition of the pole chamfer or axial cooling channels along with the Daily option, you can bump up the subs thermal capacity for long term daily driving abuse. Looking for an ultra tough higher Qts SPL sub? Choose the SPL option, the extreme lead wire, one of the 8 layer aluminum flatwind voicecoils, add power, and let it rip. With head cracking upper bass and brutal low end, the BL handles the extremes with ease.

The Q Series of subwoofers is our sound quality reference line. Featuring a hefty double stack motor structure with a heavily bumped t-yoke, the 27mm of Xmax allows for incredibly detailed, tight, and powerful bass. Dual progressive spiders keep the incredible linear excursion of this sub under control, while the extra heavy lead wire feeds the giant voice coil. Working well in both small ported and sealed enclosures, you do not have to give up your trunk to have strong bottom octave foundation for the rest of your system. The Q series is the new bottom octave benchmark.

hmm well this forum is for questions to be answered..anything can be found in research so should nobody ask questions on here??? quess not. just tell them to look it up lol
