| Re: Building IB box
No, you're absolutely right, I wasn't picking on sealed in general, but wanted to warn that IBs are not the panacea of subwoofers; there are some downsides. High SPL is not it for IB.
For example, an earlier post said "An IB uses less power than a conventional box - excursion is the limiting factor." And that is true. However, the actual sound coming out is less than half: for SPL, IB is inefficient.
If he's using drivers without the proper XMAX for IB, IB won't work, period: he'll hit the stops everytime without the air brake.
I wouldn't go sealed unless his speakers force him to be. (I'd like to clarify the 'unsealing' part of an earlier post- I meant 'increase the baffle').
