Yep, the good 'ol TC9 motor. Unless the basket is super heavy that 15" should weigh in at right at 40 lbs. A 12" packaged up and ready to go should be around 36-38 lbs. Be careful sending that driver a lot of power for an extended period of time. We used to use those same spiders and spider spacers on our subs a long time ago.
yeah I dont post much, I read though. Iam looking into selling this, and my RL-p 12. Ill be posting them up shortly, they Have been sitting for almost a year.
