Jdoris:
I'll be moving my DA-1.1's into a smaller space having moved recently--they are on their way back from Lou who performed the "All Poly" crossover upgrade while we were packing and moving. Previously I had the speakers in a 23L X 14W X 9H space that opened into the rest of the house and was thus apparently much larger. The new listening room is 13 X 17 X 8 with two openings on the long wall where the speakers will be placed. If it would help Jdoris, I'll report back on how they sound in the smaller space as well as a few comments on the crossover upgrade. With regard to the topic of this thread, I have found very few exceptional sounding speakers that were made of MDF. To me better alternatives can be found in more exotic materials or in good old quality hardwoods. Not sure if others would agree but those speakers I've heard made of carbon fiber, aluminum or other composites (like the Wilson line) tend to sound cooler and more analytical whereas those made of hardwoods tend to sound warmer and more musically involving. A generalization to be sure but this has been largely my impression based upon hearing a fairly large number of designs.
