1st order at 4000hz may be a little too high for the woofers but I guess there's only one way to find out. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Too high INdeed.

Yeah, I wasnt thrilled that they were 1st order, but they're playing full range ATM and sound fine, so i think it won't be so bad.

Yes, I know, shame on me for running wire through the port, but the terminal cups are on the way

Must be nice to be able to pick up speaker cabinets with one hand...I'll have to try that one of these days //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Just because you're "special" doesn't mean that you have to comment on others' diminutive speaker cabinets, now does it frosty?

I agree with Jim...they are cute little cabinets. //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

Crossover? That's a snack for a B3S //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

those crossovers scare me //content.invisioncic.com/y282845/emoticons/hide.gif.2d479cfd917eedfe201353b91522ceab.gif

just a simple low pass using a capacitor isnt it?

 

[PV Audio 5,000+ posts]

It looks just like a notch filter, but that doesn't make sense unless he's running either of them full range. Either way, it doesn't even appear to be first order, as most pre-made x-overs have some form of resistor on them, even though they don't really do much when you're trying to attenuate bright drivers with shitty x-over components.

Ehh, I would build your own...those crossovers don't look so hot //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

There's an inductor and a cap on the board...
