I am new to this forum and JBL, but not speaker building. My current system is a biamped slightly modified version of Linkwitz's Pheonix in a custom built (by me) scultpured enclosure. Anyway, I've always wanted some JBL's and seeing items on ebay, I picked up the following:
LE14A
LE5
LE25
My plan is to put them in a cabinet of ~2.5cf. Does that sound about right once you lose volume to the LE5 sub enclosure?
For an XO, I like the minimalist 2caps and L-pads of the L100A and will certainly try that, but I suspect something more like the L220 XO is needed. I am not sure I really understand that XO. Looks like second order to the LE14A, but what is that cap splitting two resistors, and why the 50 ohms across the speaker? The LE5 looks to be third order, but then ? notch filters?? series and parellel??? The HF will need to be different anyway so I'll just ignore that.
Does 800 & 5k seem about right for freq?
Should I follow JBL's lead at least for the LE14A & LE5?
Recommendations for the HF section?
Should I just 'roll my own' using standard formulas?
Recommendations on what order XO?
Thanks for all the help. Finding this forum made me willing to jump in and start building (the speakers arrive this week).
