2x THTLP build after a 10 year hiatus
Re: 2x THTLP build after a 10 year hiatus
I didn't get much done last night. My 16 year old son had a drumming gig for school that I wanted to watch instead. Sorry, proud dad moment
When I got home, I installed a few of the chamber braces on the second cab before I had to call it quits for the evening. I'm hoping to get some more done tonight
Re: 2x THTLP build after a 10 year hiatus
Thanks. I suppose my greatest fear is not being able to recover from a mistake.. Ie cutting a panel too short, installing with pl, and then some huge gap, hah. I guess that's why you test fit before!

I cut out the rear cover and installed all remaining braces tonight.
The next phase will be sanding, patching screw holes, roundover the edges, and duratex
Re: 2x THTLP build after a 10 year hiatus
Both cabs are technically usable, but I learned my lesson in the past about putting unfinished cabs in my living room
I plan to get all of the screw holes patched this weekend and will hopefully get some duratex laid down.

Heck ya! Our 13 year old has been taking drum lessons now for 4 years and we're lucky enough that our middle school has a separate Jazz group, so he gets to play the full kit for that.
The THTLP pair is looking great!
I had been thinking about one of these. Giving me the itch to go make some saw dust

Thanks, Tom!

--------------------
I got a bunch of work done over the weekend. All of the screw holes are patched, I installed the jackplate on both cabs, everything is sanded, etc... I fired each one up to check for leaks. At 40v they sound promising in my wide open basement in the middle of the room, but obviously need boundary loading to really come to life (as expected). It was still enough to wake my teenage sons up at 10:30am on Saturday morning with a 22hz test tone
I got the first coat of duratex rolled on. I'll do a few more coats tonight and let them dry overnight. Hopefully I'll be ready to put them in their final home tomorrow

Re: 2x THTLP build after a 10 year hiatus
I used drywall joint compound. I wouldn't recommend it for situations where the cabs get moved around alot, but I've used it on my other home builds and it's fine and really easy to work with.
I've used bondo auto body filler on the subs that get used and abused. It's definitely better for durability, but it's not quite as easy to work with.

Re: 2x THTLP build after a 10 year hiatus
I use the Bondo in a tube....no mixing. Just squirt it out, level with a putty knife.....maybe do a second round if it settles a little, then sand and go.shawn_g wrote: ↑Mon Mar 16, 2026 8:58 amI used drywall joint compound.

Oh nice. I'll have to try that next time. I've always used the stuff you have to mix and it's a hassle to deal with.Bruce Weldy wrote: ↑Mon Mar 16, 2026 10:32 am I use the Bondo in a tube....no mixing.
