The driver looks fine surface mounted and sticks out less than 1/8". The Dayton DC series mid on the Pit Viper definitely looks bad surface mounted.

    Great job on those. Yes that's the sort of "inset" look I was talking about.

    Thank you. I bought some PE black grille foam but never got around to installing it.

    Would a roundover on the baffle edges provide any benefits?
    I flush mounted the drivers, and would recommend that to anyone who builds it.

    As for a roundover, there's no reason not to. However I also figured some guys might even go with the really vintage look of having the baffle inset. So really I'm gonna say whatever you do on the baffle is gonna be up to your personal aesthetic taste.

    Paul K's numbers are spot on

    I did model what Paul C. built and documented. The 2.83v/1m sensitivity came out to ~93 dB SPL, but that did not include baffle step compensation, so the final sensitivity should be about 89-90 dB SPL I'm estimating. My modeling also showed Paul C's intentions in that around 150 Hz, the output starts rising as frequency decreases, ending up almost 3 dB higher at 50 Hz or so. Paul C. did state after I sent him these modeling results that they were pretty much what he got.

    What would you estimate the 2.83v sensitivity of the speaker.

    I know these are referred to as 'party speakers' but how do they do at lower volume levels? I know there is the whole thing with how we perceive music at lower volumes but some of the speakers I've done sound good at low, late night levels and others sound really thin.

    I know. Just kidding around. BTW, what is the resistance value of the 5.0-mH inductor in the woofer's crossover? I only ask because it affects Qts, which in turn affects the optimum system tuning frequency for the TL I've modeled for you.

    I couldn't get a .zip file to upload to the InDIYana site for the last challenge. Basically told me it was not supported.

    I think i used to know how to attach a link to things, but then the interface changed and it's a lot different now. If i figure it out, I'll let you know.

    Oh , one more request.
    Would you please post a pic of your completed crossover board for visual layout reference ?
    Thanks again
