justinsweber Posted November 6, 2010 Author Share Posted November 6, 2010 Pics to come... some serious progress made. Horn enclosure is way bigger than expected.. but will work. I stuffed the horns in and drilled mounting holes. I have some sanding to do to open the K400 openings... 1/8" too small. The Cabs are drilled for the Kappa 15C and the motor board is drilled to fasten to the cabinet. The cabs were built at 24" internal width before all my bracing, 10" shelf, 50" opening for the port. I added 3/4" to bring the internal dimensions down to 22.5" cubed. The port had a significant problem. the opening was 24" wide, and then stepping down to 22.5"... an ugly 3/4" step on either side. to solve this I cut a piece ~ 2"x10" with a significant taper 30deg. or so. Now the cab goes from 22.5" wide to 24" wide with a slight taper.... really looks nice. Pics soon!The next step is a bunch of wood putty and some sanding by hand. I cant afford to have it finished yet, so its sanding to make pretty :-) Quote Link to comment Share on other sites More sharing options...

moray james Posted November 19, 2010 Share Posted November 19, 2010 once you know the correct internal volume for your driver simply add bracing and stiffining till you use up the extra volume, bonus is a super solid cabinet with the volume you want. 2x4 braces on the rear panel sides and top will only help sound quality. making the box bigger is a harder trick to do.

justinsweber Posted November 19, 2010 Author Share Posted November 19, 2010 I got the internal vol down to 6.6 cu ft. before bracing. Its 22.5" X 22.5" X 22.5" befroe bracing = 11390 cu in. Its braced to hell and walls are 2.25" thick... Thats what I get for building bigger. Justin Quote Link to comment Share on other sites More sharing options...
pzannucci Posted November 20, 2010 Share Posted November 20, 2010 justinsweber, What woofer are you going to use, the Kappa 15C? Are the specifications for that woofer correct on the Parts Express site? Quote Link to comment Share on other sites More sharing options...
justinsweber Posted November 22, 2010 Author Share Posted November 22, 2010 I do plan to use the Kappa C... Its an Eminence 15" 40hm driver... massive magnet.I get them from Orange County Speaker… 15 miles away. I had traded some work I did for my 1st one… so the $115 for the 2nd seems a good deal. The Kappa C seems a close match to the K33 though more like the K43. Quote Link to comment Share on other sites More sharing options...
justinsweber Posted January 15, 2011 Author Share Posted January 15, 2011 All built. Im waitng for nicer jumper cables from audioadvisor. Im using 3ft spade to spade to connect the bass bin to the top hat. I had to go to work and didnt get a critical listing... at 1st listen sounds good.

justinsweber Posted January 16, 2011 Author Share Posted January 16, 2011 They sound truely wonderful... Bass is so full... not boomy but full. Shoudl I brake them in with a few hours of Pink/Brown or White noise? They were built to pair with my MC2275 that Im getting at the end of febuary. Mcintosh tube integrated :-).

Coytee Posted January 16, 2011 Share Posted January 16, 2011 JWD! (Job Well Done!) Shoudl I brake them in with a few hours of Pink/Brown or White noise? I'd say just hook em up and enjoy them. My understanding is Klipsch takes about 20 minutes to break something in for testing purposes. I'd not worry about that & just jam away.

Zoef Posted June 13, 2015 Share Posted June 13, 2015 (edited) Are there some plans / sketches availeble for a good bass bin? Englisch is not the language i normally speak, so it gets a bit more easy if i can SEE it. Want to use 15c's (sorry if this is the wrong thread.) The fact that we use the metric system overhere does not help either[emoji53] Sent with tapatalk from a lazy chair......

Stevenarrow Posted June 16, 2015 Share Posted June 16, 2015 Question: Eminance has the recommended enclosure volume for the Kappa 15C in a vented box as 2.8 cu.ft. I assume the advantage for going bigger is extended low end, but what is the trade off for going bigger? Quote Link to comment Share on other sites More sharing options...
