Here is the idea that I had for the “ultimate bass” for my room. Below is the picture of Macondo one channel as it is now from my listening position. So, if I find a way to deal with the wall edge at my ceiling  then I might replace the current 72” woofer tower with 110” woofer tower of identical width (marked in red at the photo), make it 4 deeper and put in there 8x25W driver per channel.  One 18” driver has as much air displacement as 3.2 ten inch drivers. So, 8 drivers in term of displacement are the same as two and half 18 inchers…. 

 


Romy,

I have always felt that if I went for a vertical array of 10" drivers, I would keep the drivers closer spaced than you do in your 'Dunlavy' made enclosure.

Based on the 110" height of the tower, I see that you would be doing this by reducing the distance between eight drive units to about 5cm with the planned 110" tower. I was planning to try and use 8 drivers myself if I went for such a configuration but I would try to find a way to reduce the distance between the drivers to virtually nothing.

In fact, if I could talk Scanspeak into it, I would have two cutouts at opposing ends of the frames. This would possibly in your case enable you even to have 12 drivers per tower.

Best regards
Rakesh
