Thanks Jim, hmmm, no "brand" really. I bought them on Ebay from a guy (actually lives in your neck of the woods, Bay Shore, NY) that makes them. He does a really nice job with them and can configure them anyway you want. Mine have no baffles in them, only a "star" configuration to provide some back pressure. The no baffle situation ended up giving me a bit of a prob with local noise cops, but got that taken care of. I know he can make them with removable baffles and if I was to do it over again that is the way I would go.
Anyway his name is Frank, wife is Delores and they told me to feel free and put their number out there for people to contact them. Real nice people and I wouldn't hesitate for a minute to buy from them again. Their number is 631-666-2632.
