Several reasons, push pull slot load cancels both secondary vibration and harmonic distortion. Although with IB the drivers arn't as closely coupled as in a boxed design so harmonic dostortion may not get canceled as much. There ia also some compresion because the slot has less area than both woofers together. This will increase air vilocity. Check out the link for a behind the wall project. Just copy it but point it down instead. It'll take two or four woofers.
