Hi slhijb,
I have found that the Silver-10 drivers can sound VERY good in an open baffle ..... especially if a ZROCK2 is part of the system and a Lii Audio W-15 baffle is added for low frequencies.
An alternative to the bass baffle is a good powered subwoofer.

Some additional thoughts can be found on my website at
this link.
If you are building your own baffles, you can use the Silver-10 and W-15 drivers together on the same baffle .....

Best wishes,
Randy
