I am interested in making a very light portable line array type cabinet for acoustic guitar and vocal production. My goals are a height of about 5 ft as that is the biggest thing I can haul in my car and a foot print about the size of a sheet of paper or preferably smaller with a weight as low as possible. Need to get down to 70 hz pretty solidly for the guitar. I'm familiar with they hype of the various incarnations of the maligned Bose systems and it seems their main advantage is the size/weight factor. I'm wanting something that can give me maximum dispersion width so I can tote just one cabinet for small venues.
Here are my questions that I hope someone can help me with:
1: Which would be the better option for me to order given my design goals -- the SLA or TLAH plans?
2: I wondered given how bose angles every other driver outward in opposite directions in the L1 version 2 for supposed increased dispersion and seeing the V shaped piezo arrays in many of Bills designs and the turned in twin guitar cabinet if there would be any advantage in putting two rows of small full range drivers in a similar turned in V or conversely in two rows of small drivers angled outward -- I was thinking 24 drivers in two rows of 12. I have a number of full range drivers that can go down to 70 with about 8db eq boost in the 64hz and 80hz bands. Wasn't sure if that would help dispersion or cause too much combing problems when using full range drivers. Building a cabinet along these lines isn't a problem as my woodworking skills are extensive so if the two rows would help dispersion it would be worth doing.
3: If the idea for increased dispersion in #2 isn't valid and I should just do a flat front cabinet does anyone have suggestions for light efficient drivers that are inexpensive. I saw mentioned in another forum the Sony closeouts which would be very light and the price is certainly good and with 8 or so the output/wattage would be reasonable but not great.

4: Lastly, going on scenario 3 with mid sized drivers (4.5 to 6.5 range) would there be any advantage in building a cabinet that has the drivers set back into somewhat of a V front and mounting the array of small tweeters in front of them on a small center rail (obviously no room for the piezo array in such a small cabinet).
I realize I may be trying to make things unnecessarily complicated, but I can gain an extra 20 or 30 degrees of dispersion it would be worth the complications in the cabinet design. Hope I'm not asking too much for a newbie on this forum!
