Are any of these good?  Is there another book that you'd recommend?  I'm looking for something not necessarily to build my own speakers (I doubt I have time for that) but to understand the different possible designs and design criteria for speakers (such as what affects Q; benefits/detriments of ported, unported, passive radiator).  

Thanks!

Take this with a grain of salt, but the cook book was pretty good at explaining the basics. I have the second addition that was published in the eighties and it did well at explaining T/S parameters, box interaction/configuration, X-over design, etc. Speaker designs have come a long way (including considerations for HT) since I bought my copy though. I'm sure it's been updated. If you're looking for good basic explainations, yes, if you're looking for technical papers, no.
It did give me the idea for my first IB subwoofer back then though

Bob, the Loudspeaker Design Cookbook will give you what you need. If you have any questions partsexpress.com and madisound.com speaker building forums have alot of nice knowledgeable people to help you.

Some time ago I was going to build myself some world class speakers.  To make a long story short this is a very bad idea.  Many people told me I could spend more money and more money and still end up with mediocre sound.  I'd have spent about what a pair of RM 40's cost and may have had a bunch of nice parts in a cabinet so I bought the RM 40's instead.
But I've heard of people using the Deqx to do the crossovers with.  It's pretty interesting reading.

Now that I think of it, pm your address to me and I'll send you mine, it's just taking up space anyway.
