In the Thread: Constructing LF modules to the limits

Post Subject: Here is the idea that I had.Posted by Romy the Cat on: 9/23/2011

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….

The ides is not only to get extra 9dB sensitivity from set of 8 drivers but the most important to get extra 18dB max dynamic pressure (9 from sensitivity and 9 from power handling). This would be my version of “Constructing LF modules to the limits”, considering my desire to keep the footprint to minimum, to have as driver side and time aligned and make an attempt to organize them in line-array (even though I question if it would be effective at the frequencies I use them)

Would be more effective to go for large drivers? Possible but I do not think that anyone would ever give more or less objective and definitive answer. Building the theories I see some advantages in use of large drivers and I see some advantages to use small drivers. I know that if I go for my 16-drivers scenario then I will stay with my 25W woofers that I happened like a lot. Surprisingly the biggest obstacle in me not going for the 16-drivers is my current boxes that I also like. If someday would take my current woofers from my hands then I would call my carpenter and commission him to built for me the taller boxes. I have also the boxes for 2 driver, also very good footers that can’t use in my room and probably somebody would… I hate to sell my unused any more projects but I also hate to collect all of this, my basemen looks like speakers graveyard….
