    Re: Cavatina writeup

    PE has set aside a special section of the Projects Showcase for writeups from all of the winners from this year's MWAF. I've considered it but so far I feel too lazy to do more than what's shown in my current writeup.
    Paul

    You should post pics and the write up in the Speaker Projects forum as well, or have you already?

    Looking forward to seeing you in Chicago.

    Re: Cavatina writeup

    To everyone. I really appreciate the nice comments and want you all to know I wasn't fishing for them by starting this thread. I've been asked several times for additional information; it just took me some time to get it sorted out and I was also waiting for PE to get the 2011 MWAF recap finished.

    I chose the SS mid because John Krutke spoke so highly of it. He tested the 4-ohm version but I used the 8-ohm version.

    Is the impedence from about 1kHz to 10kHz around 2 to 3 ohms?

    Thanks, Marty, I appreciate your compliments, but as you know well, the crossover design can make or break a speaker project and I was fortunate to be able to work in a stopover at Dennis' house en route to visit my sister in May.

    You're one of the best Paul.

    I plan on bringing them to YOUR Chicago DIY event in October, assuming I still have them. A friend of my son-in-law is coming over sometime soon to listen to 3 pairs of "extra" speakers I have, with the intent to buy a pair.

    Congratulations Paul! Looks like another fabulous pair of speakers, both in sound quality and craftsmanship. You just keep pushing the competition to a higher level.

    Re: Cavatina writeup

    Ever since I've seen those Philharmonic speakers, I've wanted to save a little cash up for a pair and a nice amp, use them for a reference system to compare my designs to. That's just too damn good of a deal.

    Back on track, Congrats on the award. Maybe one day I'll place in the Speaker Designing League.

    The impedance above 1k hovers around 3 ohms. I've never found that to be a problem, assuming there aren't any wild swings in phase angle, which there aren't. The critical area for impedance is between 100 Hz and 250 Hz, and the Cavatina is safely at around 4 ohms in that region. Both Paul and I torture tested the speaker with our amps, which are nothing out of the ordinary, and we didn't have any problems with stability.

    started a topic Cavatina writeup

    Cavatina writeup

    I was very pleased and fortunate to have won 1st place with the Cavatina design in the >$200 Category at the recent 2011 MWAF, and have recently completed a brief writeup on its design. This is not a "how-to" document but does contains enough information to gain a good appreciation of the design. Since Dennis Murphy designed the crossover for me, we decided to provide a link to my writeup at Dennis' new site, Philharmonic Audio:


    Using the link above will take you to Dennis' home page, and at the end of the very last sentence of the third paragraph, there is a link to my writeup (click on the blue "Cavatina").

    Thanks for looking and thanks to PE for the MWAF.
