[QUOTE="enzowho, post: 2561304, member: 568136"] 1) No, you don't want to use a 1st order crossover. That would be a very gentle slope (-6db/oct). This means the power that reaches the speaker is 1/4 when the frequency is doubled/halved. (i.e. you design a first order low pass crossover which a corner freq/crossover freq at 2000Hz. You then apply 100 watt of power. This means at 4000Hz the speaker will see 25 watts) I believe most crossovers use either second order (-12db/oct) or fourth order (-24db/oct). This helps prevent damage/overexertion of th drivers. 2) An L-pad is a combination of resistors that reduce the intensity of the tweeter. So, for instance when you buy a tweeter with 0db and -3db terminals the -3db uses a L-pad to reduce the power going to the tweeter. 3)[URL="www.madisound.com"]Madisound[/URL] or [URL="www.partsexpress.com"]PE[/URL] will have the stuff you need. 4) Off the top of my head [URL="www.zaphaudio.com"]Zaph's site[/URL] has some good resources. Google might have some good results if that doesn't help out. As for the the crossover on ebay, I'm not quite sure. If the midrange and tweeter for that driver are both 4 ohms then you should good to go. [/QUOTE]
