Consider this; A pair of JBL 4344’s, bi-amped with the LF driver having no passive crossover circuitry and the other drivers using a 3134 passive network with the three L-Pads. A dbx DriveRack Studio can provide external EQ.
All three L-Pads are set to 0dB and system EQ’ed up with the DriveRack RTA and amp gains tweaking.
OK. The L-Pad range of control can go up to +5dB on all three drivers. So the amp must be putting in that level to the network but as the LPad is set to 0dB the LPad just dissipates the rest in heat.
So my question is: if you wind all three L-Pads up to +5dB and then reduce amp by 5db (or maybe some other magical number ???) do you have the same sound but your system is now more top end efficient?
