[QUOTE="John Roberts, post: 23072, member: 126"] Re: 12v Eco project sound system Not to repeat myself but to expand on some things already said. 12V supply will limit peak output power into conventional drivers, unless switching power supplies are used, but they will add cost/complexity. One data point to consider... "old" speaker systems, decades old, before the modern generation of low cost high power amplifiers were often more efficient just to get the job done... Don't dismiss very old boxes and/or old designs. Outdoors is generally much more difficult to generate high SPL. The sound has no walls to bounce off and build up, it just goes away and bothers your neighbors. Perhaps a 4 ch system firing into a listening area from all corners might work with the 12V limit to make more sound and all pointing at the middle has less places to go. JR [/QUOTE]
