Straight from DD site.

As im glassing up about %70 of my boot im not sure on exact volume yet, should be about 5/6cubes.

If someone could plot it for 5 & 6 cubes tuned to 25hz & 50hz.

I plan on slot porting but obviously need exact vol to work it out. I want to be able to swap from music port to comp port tuned about around 50hz.

I read it is baad to tune below woofers Fs, Is this true & why?

I dont really care for massive 40-60hz where as I really do care about the bottom end. Subsonic will be set at 20hz. Amp is caliber Ca2000+ @ .5ohm.

Keen on any suggestions on volume / tuning freq as this is just my starting point.

I appreciate your time.
Brett.


Edit: Cant get those massive spaces out, meh.

For music you don't need to tune below 35/40Hz.

For SPL you rarely need to tune as high as 50Hz.

I'd design a box that tunes to 50HZ with a plug to lower it to 40Hz for music.
