Ultimate subwoofer x4

Hello guys
Just finished building 4 ultimate subwoofers designed by the one and only mark kravchenko
If someone isn't familiar with the design of the subs, it s a 12 inch front loaded horn designed to go as low as 14 hz.
It was my first time working with wood so keep that in mind
I ll attach some pictures of the build and if you have any questions i m all ears!

Now that's a serious basshead! How big is your room?

If you take yourself too seriously, expect me to do the exact opposite

Re: Ultimate subwoofer x4

Wow
I was just thinking that if your building a horn sub and it goes down to 14hz itís got to be one hell of a large box. And then I see your pics and yep, they are monsters. Great job
Where did you find the plans for them? Iíd like to give that design a try, Iíve made a few tubaís and a few folded horns with great success, have you run any REW to see what your getting sound wise ?

Helloo, thanks you!
Yes they are big boxes, big box, big output!
You ll find the plans with mark kravchenko, he s the designer of this sub, he made a comment up there send him a pm and he ll help you out, he s a very kind gentleman and he s very helpful
Regarding REW i haven't had an accurate test cause of a bad mic, and lots of stuff vibrating in the room.
