I wanted a 893 ported towers to go with my sealed 893 center, but wanted the tweeter to be at ear level. In order to get the cabinet dimensions I needed, I cut off the top woofer and re-attached below the other one, then added an extension to give me a total of 38". Actually worked well. Cabinet will be 16" deep, giving me about 70 liters net. The box will be tuned for about 38Hz. Grill covers will be part of the package. I'll post my progress as I go, but it's going to slow, because I have MS, and work very slowly. I take a lot of breaks.
