It was just missing one of the "w"s; I took the liberty of fixing it.

Electroaudio, thanks for the interesting link.

of course the below is for listening - not for sound reinforcement (then spl takes priority and freq. response doesn't need to extend much more than 35 Hz if that).

There isn't a single sub bass horn out their worth #@%# - you really need to go to about 18 Hz with room gain. The reason why is that there is information at these freq.s that are low in level but that essentially define the boundries of the acoustic space (or digital space) of the recording. Futhermore you need to have very low levels of distortion - which bass horns can help out a LOT with, BUT you still need a driver that is low in distortion even below fs (beyma makes quite a few but their levels are typically low in the bass).

The smaller the driver the smaller the horn. Exponential is the most appropriate configuration because mouth size is smaller (which is critical to getting an acceptable horn size). Of course Exponetial horns also have the greatest length. For a driver with a reasonable price and size with an elevated response in the bass. try looking at the fostex fx200 - then model it in Hornresponse.

The real problem with bass horns (other than size), is the time delay. If your placing them close to your "monitors" then you need to delay your monitors quite a bit, and most people don't want to delay their monitors.

The smaller the driver the LONGER the horn.
The mouth of the horn still needs to be of the apropiate size,
pretty big for a proper basshorn.
I do agree with you , though,
smaller driver and longer horn may well be the way to go.

If you go active , a digital crossover will take care of that.
