Hi
I have a couple of Eminence Delta 15LF's taken from a pair of bass horns. I plan to make a subwoofer that can provide a good amount of bass down to around 35-40 Hz. What kind of enclosure would be preferable for this? When put into winISD the size of the box required is generally pretty large.
Perhaps electronic equalisation is required to get a decent response down to this level (it is unlikely that they will need to be used at full power 2 x 500w RMS)
Cheers

The Delta 15LF only has an xmax of 4.8mm it will not take anything like its power rating at the low frequencies you want.
The Eminence site shows a single driver in a 165 litre cabinet limited to 175W with a steep hi-pass set at 35Hz

Xmech is quite large, I would think that a manifold type reflex cabinet would be good. The 2 opposing drivers help to reduce distortion when xmax is exceeded.
