I put together a parts list that should should be a nice upgrade for the JBL L100T crossover.
Here is the schematic.
Here are the upgrades.
Duelund CAST Capacitor.
3uF = DUELUND-71515 $391.59
14uF --> 13.5uF = DUELUND-71468 $1,100.93
17uF = DUELUND-71525 $1,379.81
40uF = DUELUND-71526 $2,526.41
DUELUND PIO Cast Copper Air Core Inductor 12 AWG Copper
.2mH = (.1mH x 2) = DUELUND-70967 $296.37
.5mH = DUELUND-74868 $403.75
1mH = DUELUND-70975 $566.01
3mH = (1.5mH x 2) = DUELUND-71555 $711.77
DUELUND CAST Carbon/Silver Resistors
1.2 Ohm = DUELUND-74958 $51.54
2.4 Ohm = DUELUND-74965 $51.54
20 Ohm = DUELUND-74996 $51.54
39 Ohm = DUELUND-75002 $51.54
Duelund Capacitors_ PIO 0.01uf / 630VDC, CAST-PIO-Cu, Copper Foil, For the bypass caps.
.01uF = DUELUND-76336 $506.76
That's a complete crossover upgrade for only $10,668.72 per speaker.
Geez, and some people say they have problems finding parts for their JBLs
