The guy in this video has the concept of the Sonic Maximizer wrong. The
concept is not time aligning physical offset of speakers. A decent
crossover/processor can do this. The idea behind the Sonic Maximizer is
that as a signal passes through the circuitry of an EQ (especially a
graphic EQ), portions of the signal are delayed more than others. The
BBE allegedly re-aligns phase of the signal. In practice, this is very
unlikely to be true.
The BBE does color the sound, adding deep bottom & high frequencies.
Decades ago, I have used them. Sometimes I liked what they did, but I
never liked them enough to actually spend money on one. I liked using
them inserted on percussion or brass/woodwind sub-mixes. With lessor
sound systems, they added brightness to cut through a muddy sound system.
If you have a decent sound system & decent mics, I wouldn't waste money
on a Sonic Maximizer. But, you might feel differently. I suggest you
borrow one, try it out, then decide if you want to spend your hard
earned cash.
