I've had several fellow AR.com members e-mail in the past week about the cabinet dimensions for the EFE DIY speaker design found here.

Madisound apparently suggests the user can increase the volume of the speaker to approximately 20 L to improve the bass response. Being a newbie to speaker building, I was a little hesitant to endorse a "mod" to the DIY design, so I decided to e-mail Ed himself to see what he had to say...

Ed's response was:

"Yes, it is true that if you increase the cabinet volume the bass will
increase. But as the bass increases you also give up a little of the
midrange tightness and purity that the DIY has become famous for. There is a
give and take for everything you change in speaker designing!

Most (not all) guys use the DIY in a surround system, usually adding a
subwoofer, therefore there is no need to have the DIY's produce more bass,
the sub takes care of the lower frequencies leaving the DIY to produce a
very clean midrange. Even without a sub, if the proper amount of insulation
is installed as per the instructions, the bass is very good for a small
bookshelf speaker. I prefer the smaller cabinet, thus the reason why I chose
it over a larger one when first designed.

Every designer has a certain goal in mind when designing a speaker, some
want as much bass as possible. I wanted a small speaker that produced a
pure, natural, tight and clean midrange, that is where 75% of the music is
produced. Good speaker balancing is the difference between a so so speaker
and a great speaker, I think the DIY has proven to be the latter because of
the reasons mentioned."

This is probably a no brainer for experienced builders...just thought I'd share.

This led me to thinking, how would it be to get ar.com to put together an FAQ for this speaker design? Any chance at all this could happen? It might save aspiring speaker builders and Ed himself a bit of time...not to mention being a valuable resource. Maybe there could be a wiki or a link or something?
Just a humble suggestion...please don't flame me..
