    Re: Deadhorse Build Thread

    Is that dip in the raw measurements also or is it there after the xo is added?

    I can be back home as early as July 8th and as late as the beginning of September, so we'll see, hopefully I can!

    You're bringing these to SEC DIY 2012, right?!? :D

    Alright, better crossover, better impedance, better impedance phase.... Just better.

    Both drivers are showing about 2.5-2.6kHz 5th Order Butterworth slopes, off-axis Sim is AMAZING :D

    The 5kHz dip is in all the tweeter measurements I've taken, I'm 90% sure of the cause and it's being fixed, tweeter was mounted badly. :o And the 10kHz peak has been in every measurement in the basement I've ever taken, can't figure out what the f*ck it is, and it's driving me insane.

    Well, I have to order a few crossover parts. I have about half of the parts required for that crossover. Currently, there's a 5dB dip that starts around 4kHz to 6kHz and the tweeter peaks at 12kHz or so.

    It sounded ok to me, but that shows my newb-ishness :o

    I also finally got my bronco running again, so I'll be able to buy and cut some wood soon

    [EDIT]: Now that I'm looking at it more, I think I'm going to try for a lower crossover point than 4.8kHz or so, since that tweeter can be crossed as low as 2.6Khz or so.

    I just love it when I can measure a deep reverse null. So.... How do they sound? Smooth? Solid center image?

    Had a sh!tty day at work, so I decided to waste the rest of my day kicking this deadhorse some more :D

    REAL MEASUREMENTS - UNSMOOTHED

    This crossover is pretty much finished.

    Yep, I was both suprised and excited. I'll work on it some more this weekend.

    I was really suprised, I even used a tweeter that wasn't my tweeter, haha! I'll try to swap out some parts and work that dip out, then it'll pretty much be ready to go

    Measurements! Real ones!

    I did this really quick, I'm driving VIPs around tomorrow, so I have to go to bed soon, but here's what I got, not too shabby, that dip gets bigger with the tweeter's polarity reversed.

    This is what I'm listening to and it sounds awesome! All that's missing is actual in-box frequency measurements from both drivers.

    Yep, go buy (3) 3/4" dowels, grab 2 or 3 scraps of MDF and stack them, drill 3/4" holes in them and glue the dowels into the holes. I had to clamp one of the dowels at a right angle.

    Took about 30minutes including glue drying time :D

    Alright, I've tested my woofer and tweeter, in-box, and MY BOX IS SEALED :D
