Band Pass filters???

Ok in the below diagram what kind of Capacitor should i use to hook up my MB Quort 8"'s??

Band Pass filters allow a range of frequencies to pass above a selected crossover frequency and below another selected crossover frequency, filtering out all frequencies outside this band. In a first order (6dB per octave) filter, this consist of a low pass filter (coil) and a high pass filter (capacitor) in series with a loudspeaker. Narrow Band Pass Filters are to be used when the bandwidth is less than two decades.

Well it really depends on some of the Drivers T/S Prameters. Like Le, Re, and what frequencies you want for the slopes. You have to remember that the Coil in a Bandpass filter hast be higher freq cut off, and the Capacitor needs to be the Lower cut-off freq.

Example, if you want to pass say 180Hz - 4000Hz. You will want a Coil pass up to 4000hz, then a Cap that will pass freqs. above 180Hz.

What model MBQ 8" do you have.

My 8"'s MBQ's are QM 200.92 SUB

Max power 125W                                       Independace 6 Ohms

Frequency Response 20-400Hz           Sensitivity 1.4W  90 dB/ 1n
