No, 1200ea. I currently have 900 to each right now. <{POST_SNAPBACK}> They will be fine, are you wiring them in parallel?

We're going to start overhauling our platform and renaming our drivers. I think LMT is going to be renamed to LMS (linear motor series) because Linear motor technology is trade marked already. We

If you want more output, go with 15's not 12's and I would run at least 1500 watts into 4 ohms rms to each driver. <{POST_SNAPBACK}> The webiste says 700 watts will get the subs to full excursion. Wont that be enough for good output? I dont have the money to invest in a second amp and an upgrade to my electrical. <{POST_SNAPBACK}> If you don't have the money, then don't go linear, The linears will push more air, but they cost a lot more because they are fitted with a ruthless motor design. The linear

Here are your numbers: 4 ft^3 two 4" ports at 15" = 28 hz. 3 ft^3 two 4" ports at 15" = 33 hz. 4 ft^3 two 4" ports at 17" = 27 hz. 3 ft^3 two 4" ports at 17" = 31 hz. go with at least two 4" ports, not three 3" ports. Thoes woofers move a lot of air and if you under port them you will have major chuffing. I would even suggest two 4.5" or 5" ports 4 ft^3 two 4.5" ports at 15" = 32 hz. 3 ft^3 two 4.5" ports at 15" = 37 hz. 4 ft^3 two 4.5" ports at 17" = 30 hz. 3 ft^3 two 4.5" ports at 17" = 35 hz.

your boston is probably shielded. raw neo's are scary to handle. I'm very gun-shy when holding them around random pieces of large metal. I have got way too many blistered from metal scraps flying at my fingers while holding the neo.

the magnetic flux is really what you need to look at. sure you can have 500 ounce motor magnets out of ferrite (Eclipse titanium pro), but you can then use neodymium's (sp?) and have tiny magnets with 6 times the flux. We use the neo's on the very expensive PA 18" subwoofers. We are going to start using it sooner on the consumer stuff, but it is more expensive. The next generation JL audio W7 will use neo, but no one is supposed to know that. I'm guessing in a few years, most all of [our] higher end consumer stuff will be using neo. The only trick with neo is you need a larger steel bottom and top plate to control the flux so the motor ends up being still pretty heavy, but the actual magnets are much smaller.

Yep they both do, Thilo is the mastermind, TC would be nothing w/o him. Re-coning your woofer? Unless you damaged it, I wouldn
