I'm new to the forum. I want to help my graduating son build a pair of high efficiency speakers to compliment his singled ended KT88 amp he built. I want a compression driver and a very high efficiency. Looks like my options with Wayne's designs are either the 3 or 4, that can fit a modest space at least.
A couple questions:
Why is there so much difference in efficiency between the 3 and 4?
How can I get a copy of the plans for the 4?
Are the kit parts readily available for the 3 and 4?
What is the approximate -3 dB point for the 3 and 4?
Thanks in advance,
Jim
