i looked at both of them and was just wondering wat r the main differences between the 2

The BL Series fills the gap between the all out SPL monster and a solid daily driver. Featuring a chamfered solid pole piece and standard double stack motor structure with 8.660" magnets 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 hyper chamfer, or our patent pending heli-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 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.

what Fi said, BL for loud, Q for sound quality. but neither is a one trick pony

What RMS can the Q be ran at safely. I know the reccomended rms is 1000 but can it handle more?

Probably 1300 Watts RMS Conservatively With BP Power, Mine Complained A Little On An SAZ-1500D When I Had It In My Truck. I Think It's A Bit Safer In My H/T Application Now.

If you are looking to push more power, just get the BL.
