Components with amp crossover?
Should I run components with the amp highpass filter or just run it flat and let the component (fronts) crossover do the job? TIA

Re: Components with amp crossover? (technine)
It depends on where the high pass filter cuts off. If it cuts off at the lowest frequency the midrange can play then run it. If it cuts off to high you wont get any midrange.
I prefer active filters to passive filters because active filters lose less of the signal
The highest gain you can get with a passive filter in the passband region is almost 1 which means some signal is always lost.

run the components flat and let the crossovers and your h/u do the job. btw going with an active setup is very costly and time consuming to deal with.

I think you may have misread that. what kind of amp and what kind of speakers? make and model, I agree with nsxxtreme.........<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by nsxxtreme »</TD></TR><TR><TD CLASS="quote">It depends on where the high pass filter cuts off.

Although a good 2way x-over can cost a few $$ the SQ and control you get with an "active" x-over is well worth the money and a little extra work, that said, the component speakers you have probably don't go lower then 40 Hz, [spec] and probably not a lot lower then 100 Hz, [real life] and if you are running a sub, you may not want them to go lower then that anyway, running them full-range is probably a bad thing, not that with a proper install you couldn't.

Passive components are more expensive.
equipment wise active is more expensive. Anyone that can build a passive crossover network could build themselves an active crossover. There is even software out there that will do this for you. All you have to do is supply the filter mask. Your costs will be less with an active filter if you build your own.
