Another build.. BL 18 in 6 cubes?

[akillj 10+ year member]

How will the BL 18 preform in 6 cubes? Going in the back of an expedition. Will be tuned to 30-32 hz, what do you guys think? Will it still hit the LOWS (Below 30)?

Why wouldnt it?

From what I've heard those like a bit bigger enclosure. More towards 6.5-7 cubes around what you were saying. I'm going off from what I've read and have been told.

Why wouldnt it?

Because of excatly what blobb just said. I don't want it to be too small. Will be ran off ~2k. I wasn't sure if it was TOO small and it would be choked.

6 isnt tht small but on 2k u might wana bump it up to 6.5 i think it will still do good at 6

The size and tuning are not the only determining factors. How much port area will you be using?

Sounds good. Would this be ideal as a daily? My buddy is going to use it as a daily. Should this sound better than say, downsizing a bit and picking up a 15" BL in 6 cubes instead? (Same setup, 2k RMS @ 32hz).

Not sure. I was probably going to have a box built. I thought port area determined tuning? Or do I have it wrong?

Yes port does determine tuning

Port area, port length, and box volume are factors in tuning. When you say 6 cubes is that before sub and port displacement? If so a 15 would be a better option.

Is 6 cubes as big as he can go?

Exactly now if ur talkin 6 cubes after sub n port displacement i dont see a problem

I could go bigger, but i'd have to build my own box. What exactly would be the 'difference' between the 15' and the 18' in optimal boxes ? On the same power, would the 18 play louder and lower?

More cone area in optimal setup always wins

What exactly would be Optimal for each? (after displacement)
