100 Hz Low Pass 4 Ohm Crossover
Impedance of crossover
What is the Impendance of this crossover that will be added to the amplifier?
This should have a 9mH inductor which if these use the 18 awg I core sould be 0.56 ohms.On a side note if this does indeed use the same 18 AWG I core inductor as part 266-578 it is cheaper to buy these then the inductor by itself, but that makes me question if these do use the 18 awg inductors.

Two drivers using Hp & Lp ?
Building my first project speaker.I'm going to use a 15" Boston Acoustic subwoofer and a Goldwood GW-10PC-4 10".What i want to know is, if i'm using a 100hz Low pass Filter for the 15" and a 100Hz high pass filter for the 10", will my impedance will stay a 4ohm because i'm using filter ? Or it will drop a 2ohms ?Thanks
It will stay at 4 ohms but may drop to 3-3.5 around the crossover point. This is fairly typical, if you have an amplifier that handles a 4 ohm load this will not be a problem.

for a dvc (2+2ohm)...
if i combine both 2ohm coils on a sub to run a 4ohm load from amp, do i still need two of this, one for each coil, or can i use the 2ohm coils wired together/4ohm with a single one of these low pass filters?
If you wired the coils in series for a 4 ohm load you only need to use one low pass filter between the subwoofer and amplifier.

What type of 2nd Order Crossover?
Is it Linkwitz-Riley, Bessel, Butterworth, or Chebychev?
This (and all our pre-made crossovers, unless otherwise stated) is a 2nd order Linkwitz-Riley configuration.

will this work for a sub woofer?
i bought a 2.1 amp, but it has a poor subwoofer crossover, if any at all, i mean it sends all frequencies to the sub, would this crossover work?
Yes, the 266-444 100Hz Low Pass crossover will work well for subwoofers. The 4-ohm design impedance, 100Hz frequency cut off, and 12 dB/oct slope all would suggest that it is ideally suited for use with 4-ohm subwoofers. Though I don't have this item myself, the 280uF capacitor would suggest that this crossover has a 9mH inductor and a Q of 0.7. This crossover would not work well for 8-ohm subwoofers since it would produce a 3dB peak in the response at 100Hz.The down side to using this instead of a preamp level crossover is that some of the amplifier power will be wasted on post-filtered frequencies.It is odd that the 2.1 amplifier's crossover isn't filtering the high frequencies on its low-pass output side. The amp has a built-in 12dB/oct crossover with variable cut-off from 40Hz to 240Hz. Maybe it is not working properly.

Will this work with 2 8 ohm subs wired in parallel?
Sure will. Two 8 ohm subs wired in parallel gives a 4 ohm load.
