That size woofer in too small a cabinet and that many drivers in the box scream Kabuki.
Kabuki is pejorativeve term for speakers that have a woofer too large for the box in an under damped configuration with too many midrange drivers and tweeters.
They generally sound boomy with no real low bass. They aren't considered collectible or particularly desirable. As with anything else only your ears can tell you if they are worth the time and effort to make them sound decent. My personal inclination is to not bother with "Kabuki" speakers.
