Mine are alll flac files fron the internetz. Thriller Special Edition 2001 and Thriller 25th Anniversary Edition, neither of which are spectacular, dynamically speaking. It appears there's an SACD and many vinyl cuts plus some digital downloads out there in the 17-18 range. I'm sure they'd really slam the crap out of those tweeters. Thriller, Original Vinyl : DR17 -0.05 dB -18.01 dB 06 Billie Jean.wav Thriller, Acoustic Sounds DSD download: DR18 -2.57 dB -21.37 dB 4:54 06-Billie Jean Thriller SACD: DR17 -0.44 dB -19.04 dB 4:54 06-Billie Jean Source: http://dr.loudness-war.info/album/list?artist=michael+jackson&album=thriller Michael Jackson wasn't really on my radar as I've always thought of Thriller as music for 10 year old girls. But then I went to buy a Rane AC-23b from a guy described as 'a bit eccentric' out on Tybee Island. I get there and this guy is over the top, for sure. Retired electrical engineer. Entire system handbuilt. Speakers, tube amps, tube crossovers! None of the manufactured stuff is good enough for him anymore, hence the sale of the Rane. I have to just about beg the guy to let me hear something. He selects a Thriller 'half speed master' (not that I have any idea what the hell that is at the time) And he tells me offhandedly that Michael Jackson had the highest standards in the studio. So, he lets me hear about 30 seconds of it, VERY loud and phenomenally clear. Stops the record and I'm kinda standing there open-mouthed. He hands me the Rane, takes my money , and dismisses me, still stunned. That was about 5 years ago. I'd love to hear that setup again.

I've lost count of how many tweeter fuses I've blown with Billie Jean.

I enlarged one hole with the file included in a Swiss Army knife. While it didn't take very long, it did slip and mess up the finish on the bottom. Needle files would have been so much easier, had I thought to bring them. Alex loaned me a step bit which I used on the other hole and the size was perfect. It was similar to the one on the left in the pic below.

3/8 = 12/32 = One 32nd less than 13/32 = One 64th difference on either side of the hole = A teeny tiny bit of wiggle room = Slightly less of a chance of screwing up the threads on the binding posts.

I assume both sets of pictures (this post and previous post) are in the metric. PS: Re-read the previous post. Thanks for clarifying. Yeah, most of the plate dimensions looked like they were in inches. I'm assuming that all of the components resistors, caps, etc are in mm. Any idea what the lead time/cost would be for these boards?

Note: These dimensions are in inches

Here is an absolutely awful drawing of how I wired a set. XLR pins 1 and 3 are easier, so many people did it that way. (I chose 2 and 3 to correspond with hot and cold in the XLR standard) The black and the long 'yellow" wires weren't cut, just stripped in the areas where we wrapped them around the terminals. (TNRabbit's idea) /yetanotherforum/uploadimg/20150923180610958.jpg You can put the speaker on its back and set the woofers and bottom plate next to it exactly like this with the ribbon on top and run all of the wires. Note the orientation of the small and large pins on the woofers.

The stand has a pretty big opening at the top of it. This is the top plate for the stand.

Thank you B-Man. Stroke avoided.

Guess that was a screw up. Sorry Greg. It has been pissing me off for five years. It's like it's taunting me. Everyone hates it. It's the Carversite equivalent of Nelson from the Simpsons. Ha Ha you forgot about the goddamned copy thing.

Completely off-topic... Does anyone know who wrote the post editing software? Every time I try to right-click to copy and it tells me "use ctrl-c" I WANT TO KILL SOMETHING! Why the hell would someone code in a popup and not just do the damned thing you want it to do? Is there someone we can pay to make this work?

Great catch. I didn't even notice that. I'm not worried about the rotation aspect because the XLR isn't a twist on type of connection. However, I wonder if it will still seal in a round hole. Perhaps the tiniest bit of clear silicone around the outer flange... I don't care about the seal on the female connector. Or are you thinking the connector requires the female to make a seal? Jeez, this stuff gets complicated rather quickly.

Z, thanks for all of the great options, I'm going to read up more on those. Who knew there was a locking TRS? Very cool! Best thing I've found so far is this: Neutrik NC3MPR-HD Yeah, I said I didn't want an XLR, but I like the one-hole mount of this one. I tend to get the ones with the two screw holes all out of alignment. (Which is sad because I drill and tap thousands of holes at work in panels with no issue - go figure) The NC3-MPRs are IP65, so probably not much air leakage. The only thing is the 50V rating. Neutrik doesn't make a speakON which mounts like them because of the force required to connect/disconnect.

Excellent advice. Thank you! Just want to add a bit to this one... Several people have wanted to trim strands off of the supplied wire to get them to fit those tiny XLRs. Please do not do that. Hooking these up is really difficult and B-Man's method was the only way I could get it to work. While the mini XLRs will suffice, there are better solutions out there. I have to do a Mouser order today for the job. Anyone have any suggestions? I'd rather not do full size XLRs but would prefer something larger than these and also air-tight. Would a TRS just fall out? Locking RCA, perhaps?

Any chance you have pics of both sides of the board?

3 colors on the ones I built and no instructions. I wired them black to-------- xlr pin 3 bottom 2 woofers neg (small terminal) neg on ribbon Red from xlr pin 2 to crossover Another red from crossover to ribbon pos Yellow from crossover to top two woofer positive (big) terminals Another yellow from top left woofer small (neg) terminal to bottom left woofer pos (big) terminal Yet another yellow from top right woofer small (neg) terminal to bottom right woofer pos (big) terminal Yeah, the top woofers had both wires the same color but it was easy enough to tell which was which when I replaced one.

Just so you know, it wasn't intentional. We were just jamming. Surprising that they sound great all the way to destruction. No one else realized that they blew. I just happened to be closest to the right speaker. It was the top right driver that went. (the one on the right in this pic)

We played them very loud for quite some time. When they did blow, it was one woofer. The entire chassis was hot. When Jazzman and I removed the woofer, it was so hot you could barely touch it. I'd suggest that if you decide to play them absurdly insanely ridiculously loud, check and see if they're hot to the touch. If so, turn them down and let them cool a bit. Oh, and the 400~Seven is 800 4 ohm watts. This stereo pair was running on two 400~Sevens with one other channel on each driving a paralleled pair of 15" woofers.

FWIW, I've done electrical connections in wet locations underground and taken them apart 10 years later and the 130c was like new and not brittle. I don't expect the resistor or inductor to overheat before the woofers smoke as that was what died first in our torture test.

3m 130c Also known as rubber splicing tape is exactly the width and makes a perfect insulator if you stick it to the bottom of the resistor

Additional Dire Straits honorable mention... At Carverfest 2011? TNRabbit brought his actively biamped ALIIIs, a massive bank of modded Minimus speakers as surrounds, and an over-the-top Klipsch? subwoofer, all driven by a Sunfire 400 seven. I will never forget hearing the SACD of Brothers in Arms through that setup in Cabin 5. It was a top-ten lifetime audio experience & I wasn't even in the sweet spot.
