Re: Jl audio 13W3V3-4 40 liter closed box: The best of one world

Did you design the enclosure yourself or did you buy it from somewhere? I too am seriously considering to build 2x JL audio 13" subwoofers for my HT/music system. I'm deciding between the W6 or W7. What would you recommend? I am thinking of purchasing the diy sound group flat packs for 1.5 cu ft and building a tripath amplifier from PE. What is the lowest hz you've hit on that sub with palpable output?

I build this box myself,it,s 40 liter,s .
It,s easy whit JL drivers u use the closed box the use in the car.
So i buld this box myself,butt like JL would do it self,arround 40/42 liter is ok for a 13W7

I would buy 13W7 ,the W7 will me more for HT use whit his high Xmax.

The lowest palpable output after dsp ussualy arround 15 -20 hz,after use of DSP ofcourse.

I've chosen my design. It will be a isobaric configuration with 2x JL Audio 13W6V2D4 and a Behringer inuke 3000DSP amplifier. The subs have 2x 4 ohm voice coils that I can wire in series and get 8 ohms per woofer and when connected to the amp get 4 ohm combined. That should get 750 watts for each woofer with dsp. Then I will go use 1" thick Baltic Birch Plywood and 2" thick baffles.

Amp en the JL,s match fine like that.
Inuke give,s 2150 watt RMS mono at 4 ohm,that wil drive your drivers just fine.
Nice project,i,am looking forward to seeing your build.

This finish is done after about 5 coats of automotive primer then block sanded. The black is gloss spray paint from a can. Live by these words. " it's all about the prep job "
WOW, that looks like it was done by a pro (as if you purchased it from a mainstream high end speaker company)! Very nice work!!!

Happy Listening!!! Listen with an open mind and heart!!!

Morca,

That's actually an extremely good job for your first build. The sound is more important and if your happy with that...

Well it was sorta done by a pro in terms that I am a painter by trade. I paint cars for a living. Shiny paint is what I do. Lol

That explains it! I would think cars are much harder due to all the curves.

Believe it or not you can pretty much teach a monkey how to pull the trigger. Painting is much more involved than just applying. To me what makes a good painter is knowing how to fix problems on the fly and how to assess the job and go about it properly. I.e. color matching. Knowing the substrate and how to prep said substrate properly so you can get good adhesion. Anyone with questions on how to get a nice painted finish feel free to pm me with any questions that you have. Now back to this mans thread ! Sorry for the temporary thread jacking.
