Lab sub. 12" ???????
« on: December 25, 2009, 06:26:29 AM »

Hi there i got 2 x1 for my TMS4 Turbosound cabs, but i´m after building some horns cabs to see how they sound.
Sorry if this may sound a bit stupid, but i´m new to the forum:
The lab sub seems amazing and have good reviews on sound, but i just thought it was a 2x18" cabinet... am i wrong or is it a 2x 12" cabinet??
The dimensions of the plans seems huge... so i´m quite confused.

Ok ,so the subs from this stack only has 2x (2x 12")???
It just surprise me i thought it was 18" speakers...

index.php/fa/27022/0/


And is it really worth to make such a big cabs with 12" in stead of 18",21",... for subs????

I´m sorry i´m asking this so many times but it´s strange to find a subwoofer cab with this configuration used for pro sound lows.

With horns- it is not so much the size of the driver, but how it is used that makes the difference.

You will find that the Lab sub outruns all 2x18" that I have seen or heard.

Sam,

you should go back and read everything about the labsub before starting a build.

Maybe you dont know, but they are designed to work in a group of 4 boxes to give their best. 28Hz - 90Hz is the recommended use in group of 4.

If you still decide to build them make sure that the back chambers are sealed and to use at least 18db slope HP filter at the recommended frequency.

And be sure to use the proper 12" drivers (lab 12 by Eminance)

Sam, take it from me, building the lab sub should not be taken lightly. As said in previous posts, you really should be using them in groups of 4. With that said, i spent 6 months to build 4 of them Shocked Of course the results were worth the time and money, but it is a TON of work to do them right. You need the space, the tools and the patience. Count on spending 3-4 grand on them. Dont start the project unless your serious and dedicated. With that said...have fun! Laughing

Following is an idea of what's involved (I say idea, because one may not notice from the pics how many of the panel cuts involve  angles or even compound angles that must be spot on):
