Audio circle have a dedicated section on open baffles, hundreds of threads. I have built open baffles with various drivers, lowthers being one with 15" eminence alpha bass drivers. I found making an open backed box for the bass was better. It's very easy to get good results with little knowledge. Trial and error is fun but audio circle will help.
