I would like to build a passive diy-speaker using 2 lowfreq. woofers.
Unfortunatelly almost all JBL´s like the 2235, LE14h, 1500FE, 2216nd are 8ohms... Using 2 woofers per box sums up to 4ohms nominal impedance. But I expect the minimum impedance to be as low as 2-3ohms...
Most amplifiers are 4ohm stable.
I´m talking integrated amps, not seperate amps.
What happens when I run dual woofers as described which could have a minimum impedance even below these 4ohms?
Looking at the JBL DD67000 Everest it claims 8ohm nominal impedance.
Resulting in 8ohms total the dual 1501al woofers should be 16ohms each I guess... That should be easy to drive for amplifiers...
But the older 4435 had 4ohms nominal impedance with the dual 2234 being 8ohms each...
Same with the Westlake Audio BBSM-15 with dual JBL 2235 woofers... Westlake claims 4ohms nominal and 2ohms (!!!!!) minimal impedance.
Now that should be much harder to find a capable integrated amp?
Best regards,
Olaf
