I have a single, new, XT18WOO8, its the reddish brown wood pulp as opposed to the woven glass. Bought for a spare, but no longer have the system. If you are using them in a system, buy a spare, they are very intolerant of over-excursion. Mounted in the baffle of my existing speaks to check the frequency response with JustMLS to make sure it matched. Otherwise has just been sitting there. Neglible evidence of screws, zero hours. $45 plus USPS Priority Mail of $11.35, lower 48 USA only. Contact Greg at gcgivler at yahoo dot com
