DONE! 4-way home build

I think you owe us a confession.........you built that entertainment center, too, didn't you? :D

Nice work on the speakers, a very high quality build. I especially like the blue baffles, as others have said, kind of JBL'ish. I can see from the pictures that you are an experienced woodworker, the dust collection and DIY sawhorses are a dead-give-away.:thmbsp:

I had posted in your thread asking about the JM fiberglass board and I'm glad to hear that worked out for you. I am thinking about replacing the R-13 I used in my DIY speakers with the same kind of glass you used. Did you line the entire carcass or just certain panels?
 
Very nice work. You should be proud.
How exactly did you do the blue baffles. What material, finish, etc?
 
Very Very nice work. I am impressed. There must be some AKer in your area that can take messurments. They looks SOOO good, might as well tweak them sonically as well.

However, if you want to drive 5 hours, we could test them here in the D.
 
:music:Choosing the crossover points proved perplexing! (say that 5 times quickly) I ordered the Pyles and the Dayton crossovers at the same time planning on splitting the 625-5,000Hz range between the 5" & 8"mid's. When the order showed up the low range was designed for 8 or 4 ohm loads via a jumper on the board. Not wanting to harm my Marantz 2285b, I decided to use the 8" mid with the 12" woofer below the 625Hz cut off. Originally I had planned on about 2-3 octaves per driver with a strong mid section. Splitting the low range required adding a 1st order filter to limit the 8" somewhere above it's low end capability of 200Hz, so I targeted 250Hz. I think I'd like to try some 8" woofers in place of the mid's. As far as the insulation I lined everything except the front panel. I'm open for suggestions, I can easily remove individual pieces. Getting that blue front also caused problems. I purchased anodizing 2 step automotive paints and attempted to verify them as enamels (unsuccessfully). So I shot enamel primer and tried to top coat only to find out that the 2 step was lacquer. Not soo good! I finally shot some more automotive blue metallic over the entire mess and still have some reaction crinkles, but it's blue.:tears:
Here's a better view of the Trusonic/Utah woofer made in Huntington Indiana, many years ago.

Wow!!!!!!!!

:yes::thmbsp:Holy -Crap-a -Moley! I didn't completely believe the techs who talk about burning in new capacitors but I'M A BELIEVER! These speakers are really changing the more that I play them. I even dug out some Rush 2112 and I closed my eyes and I was back in junior high. ( no chemical stimulus) As a young friend of our daughter's said "those are really tight!":banana:
 
Great looking speakers. My question is, How, if I may ask, did you cut the holes to mount the speakers? Was this done with a router?
 
Holes

Yes all the large holes were cut with a router & a jig that I built. The holes closer to 2" were done with Forstner bits.

I was afraid that I had deadened my cabinets too much lining all inside walls with the fiberglass duct board. They had nice comfortable sound and played plenty loud but I was still a little disappointed, I was missing the nice sound and feel of the drum claps, no matter how I adjusted my EQ. Just before Christmas I picked up a Marantz 2252b on E-bay and swapped out my 2285b so that I could start a recap. OMG! That 2252b brought these speakers to life! Those sharp claps were there in all their glory! Complete with the feel in my chest! Wonderful! Now my work is cut out for me on my 2285b.
