That bass front loaded horn seems the best way to go. Not an option for me because of available space.

What is a 2nd best option for bass enclosure ?
I am reading the internet to try figure out pros and cons of Bass Reflex, Onken, Sealed, etc.

For a relatively small footprint with high sensitivity down to around Fb, a bass reflex is the way to go.

High sensitivity low cutoff <40Hz = big bas reflex box 100-250 liter

Small basreflex box <100liter and High sensitivity = high cutoff frequency >50Hz

A other option as a Basreflex would be tapped horn with small subbas speaker. Onken is also a basreflex tuning.


A very small sub is made with a ripole only efficiency will bee not so high. But the smallest you can build to have high power use two 18".Click the image to open in full size.

In one of the first post I did show the 15mb606 100dB 1W and cutoff about 40Hz. That is about the physical limit foor a 15" BR..

That horn driver combination has only half the dispersion at 15K as at 1K.
If you consider that good dispersion, what does a bad dispersion look like ?
