[QUOTE="thylantyr, post: 2707470, member: 560358"] You can do some listening sessions to see if you can optimize the project more. [B]I believe that there's a 4dB on the tweet and a 2 dB on the woofer. [/B] If you do 0dB on the woofers and 2dB on the tweeters, the results are the same but the speakers will get more power from your amp with this config because there is less attentuation on both drivers types. [B]The tweeter was outrageous[/B] I still haven't figured out what your tweeter issue is... skinny ? Keep in mind that some resistors of low ohms are wire wound, I don't know if you snagged regular ones or non inductive resistors, because wirewound resistors are inductors and you will get some low pass action on those tweeters filtering the top end off. I don' t know the specs so I can't say if that effect is taking place, most likely it's outside the audio range. [B]and even with the new slope, the woofers still had some peakiness. [/B] .. because the L-pad doesn't affect FR [assumng non inductive l-pad] [B]Using the Dayton Reference Series 7" woofer [/B] People that use this driver use 4th - 8th order crossovers to filter out the nasty break up modes. [URL="http://www.partsexpress.com/pdf/295-374g.pdf"]http://www.partsexpress.com/pdf/295-374g.pdf[/URL] If you turn off the tweeter and just listen to the woofers, if you hear any high frequency sizzle {fo sizzle my woofinizzle}, then you need a steeper slope and/or lower crossover frequency. If it sounds good to you as is, leave it alone. If the tweeter SPL in relation to the woofers is not high enough, then bypass the l-pad and do another listening test. This is where a DCX comes in handy. You can figure all this out in minutes and determine the best crossover and you can translate those settings into a passive crossover design [or keep the DCX on the speaker]. If you migrate to this methodology, you'd be taking a huge leap forward vs. traditional methods. [/QUOTE]
