I finished up my Madisound Recession Buster build yesterday.  For full documentation of the build along with lots of photos, see this thread:

I spent about an hour listening to various types of music last night; Weezer, Metallica, Muse, Busta Rhymes, Aphex Twin.  Most of my mp3 rips are 300kbps.  I'm no audiophile, so I don't know if I am using the correct terms to describe what I am hearing.  I can best describe these speakers as sounding transparent, smooth and neutral.  These are the first speakers I have owned where the sound does not seem to come directly from the speaker, but from all around you.  I guess this is what people mean when they say that a speaker has good "imaging".  In all regards, they beat my JBL Venue 5" monitors which I use as mains for my HT setup.  The JBL speakers had an MSRP of ~$200, they are now discontinued.  (I paid $80 on an open box super duper closeout deal).  The specs say the weight on the JBL's is 7 lbs each, my Madisounds are a beefy 17 lbs each

Total build cost on my Madisound kit was ~$120 after cabinet materials, accoustic foam, terminals, paint, sandpaper, etc.  I only have the JBL speakers to compare to, but after hearing how much the Madisound outperform the JBL speakers, I think they would hold their own against most any speaker in the $200 to $300 price range.  I still enjoy the JBL speakers, but I think most music listening will be done on the madisound speakers, with the JBL's used exclusively for movies from now on.
