Steve ... I just got feedback not to use my PA woofer (P.Audio C18-650L) for an LLT, mainly that I need a more linear driver and heavier cone. My 18" has 15% excursion (0.75mm of the 5mm xMax) at 25hz for 100dB vs. a BMS 18" that is 12.5% (1mm of 8mm xMax) at 25hz for same 100dB. Mms of PA is 178g and BMS is 195g.
Seems close enough for me. The approx 260-300 L's tuned to 16hz looks OK.
Is there something else I should consider?
I have not addressed the spider and surround stiffness especially for lower operating levels. It has dual stiff spiders.
Can you help?
BTW, now I get to read your entire first post again for the 10th time. tee hee
Thanks, Zene
