Pjay's Speaker building page

Welcome and I hope you enjoy the site. E-mail me at: Pjay

11-2009: Cleaned up a couple of links on Boxycad and the Guru section. Sorry some links were dead. I need to clean up the "links" page, these change so often it is hard to keep up. Missed RMAF this year and am really bummed. My company sent me to Mozambique Africa for two weeks just befor RMAF and the thought of 18 hours on a plane from Moz, three days home, then another long flight to Denver was too much. Hope you saw my picture in Stereophile in July.

2-2009: Added three projects under the project menu.

1-2009: Wow, another year. Just collected all my show reviews and put them under on menu link. Hope you like them. I still have not completed the last two pairs of speakers, will post them when they are done.

11-2008: Well it has been a long time since I updated the site. Mostly I have been busy at work, new job needs attention and I have to pay the bills. I completed a really nice 3-way using Scan-speak woofer, Seas mid and Seas tweeter. Sounds awesome, probably since Dennis Murphy did the XO. I completed a ProAc clone rev 6.0 from the Troelsgraven site and sold them in the first 15 minutes. Darn, they sounded really good too. Mostly completed a Scan-Speak two way and a Aurum-Cantus two way. Will post pices when I get the chance. Mostly I am trying to get the site back on-line since AOL decided to suddenly kill all user sites. So now we will see how long Cox lasts. Since I actually pay cox for cable, they better not drop me. Also, went to the Montreal audio show, tres cool. I know a few of the links are dead and some pics are missing. I just don't have time right now to be comprehesive. The good text is there. Thanks!

3/2007: Pack your bags, we are headed to the Home Entertainment 2007 Show! Thanks to JA for getting us a room, Ray Kimber for supporting costs. We will be in room 1627.

2/2007: I made it to 100,000 hits! I added some writing including the RMAF 2007 report (click the Writing and Rash Opinions tab, or open a new page here) . Looks like we might be taking this to NY for the Home Entertainment show! Built a new 3-way with SS woofer, Seas top end. Will post pics later.

I have been adding to this one and it is some of the most interesting reading (not my writing) I have seen on Audio.
