I'm designing an MTM speaker using a pair of VIFA TC14SG49-08 5-1/2". I want the setup to be as efficient as possible, without presenting a difficult load to my receiver, which is only rated for 8 ohm speakers.
I want to wire these to speakers in parallel, and use a 3rd order filter at 2000hz along with a impedance compensation circuit. The problem with that configuration is the impedance will be very low, below 4 ohms I believe.
My idea is to not use the impedance compenstation circuit. This would give me a shallower rolloff, and require the use of larger inductors. If I use a small guage, the larger inductors should increase the overall impedance to something above 5 ohms (hopefully). Any thoughs?
I'd hate to pad down the woofer since that works against my objective of efficient speakers.
