I got home today and was listening the music of my carpenter in my basemen cutting the wood for my midbass horn.  I was slowly thinking about the location of my perspective lower bass channels. The Midbass Horns, if the things go well, will cover down to 40Hz and I would like to have another 20-30Hz sealed box channels. Ironically the requirement is the same – I would like them to do the job but do not destroy the room decor – or not to be too mu8ch in sight. Suddenly it hit me what I can hide the LF channels.

Two days back I have a structural consultant inspected my project and he gave me some recommendation what in his view heed to be done. I said him that the weight of each horn inhaled in attic was 1500pounts of 3000 pounds combined. Some of his recommendations I discard but some I find need to be implemented. So, the in the room will be installed an extra vertical poll to support the horns in the middle. It will be 75” behind the listening position, not too disturbing, still leaving a plenty room on the side wide open. I will probably cover this pall with drywall. In the image below it painted with dark blue behind the listening chair.

Then I asked myself – why do not convert the space behind this new wall into a large LF channel with two L and R drivers in opposite side of the walls – shooting in kitchen and in reading room? I measured the space and I got 83 by 25 by 35 inch or around 35 sq foot. This is perfect to make two 12-14 sq foot LF channels with Aura 1808 for instance.

The idea is very elegant and the woofers will be absolutely not intrusive or visible. I need to measure this space and to see if it is a “hot” space in the room. There are some concerns however that I do not like. Firsts is that the distance between the R and L channels will be less than I would like it to be. The second is that LF souses will be BETWEEN the MF islands and this is VERY bad in my books. The woofers will be closer to listening position than anything else, to make delay for LF is not a problem however.  I need to think about it more. The idea is promising but need to be examined more.
