I've got TimeWindow 3's & 7's and they're irreplaceable. It's amazing how you can tweak their sound just by moving them 1/2" forward or back. It should also be noted that the imaging of these speakers can be fine-tuned by simply rotating each speaker by a degree or two (slight toe-in or toe-out). These speakers need to be spiked and, in the case of the smaller TWs, placed on short stands. Shot-filled Lovan Jazz or similar stands may work, though a cheaper solution may be to try cinder or concrete blocks under the speakers. Stable and acoustically inert, concrete is actually a great material in audio. If a concrete block improves performance, it may be wrapped in carpet or heavy cloth to match the room's decor. I would still use spikes or hard cones under the speakers for proper drainage of cabinet vibrations.
BTW - On the topic of DCM re-introducing the TimeWindow, DCM had some very expensive cabinet making machinery and tools that were used to make the uniquely shaped TimeWindows & TimeFrames. When Mitek bought them out, I believe they SOLD ALL OF IT, solidifying Mitek's objective of running DCM as a value-based manufacturer. I've read some good things about the new TimeFrames; it'd be interesting to hear them.
