(2) 12" subwooder build

Recommended Posts

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 smile.png

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.

TC Sounds 18" PR's smile.png these things are huge. The spiders are as big as the 12" cones.

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.

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 smile.png

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.

Wouldn't that ruin the coil?but I know nothin about building a subwoofer

Prolly change the impedance up as well.sorry about my spelling

I 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.

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.
