am spoiled by the big sound of my Silver Iris.
The big sound can be appealing to some, i find the lack of midrange definition, and the 15" operating with a huge number of breakup mods not at all to my liking. The only OB speaker i've heard that sounded boxy because the 15s break-up modes kept drawing attention to the speaker. I'd take a set of Mar-Kels over them any day.
The SIs were a big hit with a lot of people at the 2009 diyFEST where they were playing outdoors... just shows we all have things we prioritize in our sound.
