Posted December 1, 201311 yr I am making my first attempts at subwoofer building. I never reconed or built a subwoofer so I am learning as I go. Top priority for these subs is to have a low qts since I plan on using these with passive radiators. Suspension compliance is really a stab in the dark at best. The motors I am using are built by TC Sounds for Lightning Audio. They have a cool neodymium slug and a huge top and bottom plate. The baskets and cones are made by TC Sounds as well. The baskets accommodate six hole mounting points. I needed to drill mounting locations for the four hole motors. I sent the baskets out to be powder coated. I should have them back in the next couple days. The motors have a lot of steel in them. I think they need polished Before/After I am using the TC Sounds aluminum cones. With the TC Sounds 1" spider spacer there isnt enough clearance between the cone and the top spider. I cut my own 0.50" spacers out of ABS. I'll get more pics up soon!
December 2, 201311 yr Author A few pics of soft parts. Coils (8 layer aluminum flat wire) and spiders. 12" aluminum Cones wiith 3" collars. TC Sounds 18" PR's these things are huge. The spiders are as big as the 12" cones.
December 2, 201311 yr What? Another PR setup? Awesome!!! The rebuilding of those subs is looking good man. Keep up the good work.
December 2, 201311 yr Author What? Another PR setup? Awesome!!! The rebuilding of those subs is looking good man. Keep up the good work.Hecks yes man! Thanks! I love pr setups ever since I heard my first Kicker dual 8" subwoofers with dual 10" pr that they used to sell. I got my baskets back today. Pictures do them no justice, they look awesome! Here are a few pics nothing is mounted/glued, parts are laid on the frames for pics. I was happy to see that my 0.50" ABS spacers will work. I needed more clearance between the top spider and the bottom of the cone for the collars to sit.
December 3, 201311 yr Author Whoa that looks sweet!! that's tight! Lots of work and time went into that.Thanks fellas. I am hoping to have these built within a week, we'll see.
December 3, 201311 yr Author What are the T/S going to be ?I have no idea. Just a guess based on manufacturer specs using similar parts. I am hoping for a qts suitable for passive radiator use. Even worse would to have them performing horribly. In that case I may tear them down and rebuild using different soft parts. It would have been much cheaper and probably of had better results buying a well designed subwoofer. I am enjoying this experience but I know the odds are against me
December 14, 201311 yr Author As you can see this is a slow build. I am in no rush. Although anxious to hear them. The motors are mounted via stainless hardware. As I expected the coils are a tad too long. With the cone in position I will need to remove 0.400" from the coils. I plan on doing this today.
December 14, 201311 yr Wouldn't that ruin the coil?but I know nothin about building a subwooferProlly change the impedance up as well.sorry about my spelling Edited December 14, 201311 yr by garychurch84
December 14, 201311 yr Author Wouldn't that ruin the coil?but I know nothin about building a subwooferProlly change the impedance up as well.sorry about my spellingI am cutting the former not the coil windings. This does not effect the electrical properties of the coil. The weight of the coil will now be slightly less.

December 15, 201311 yr Author I trimmed 0.450" off the formers. They cone assembly fits in the baskets perfectly. The coils and spiders are fitted and glued. I am using my 0.500" ABS spacer between the spiders. The bottom spider is mounted top down (flipped) compared to the top spider. I wasnt sure what I was going to do for speaker wires. I was thinking about direct leads. I decided to go with normal connections but now I have to wait for the parts to come. About 7 sheets of paper for shims. Coil/spider assembly.
