[QUOTE="Daniel Cumberland, post: 23131, member: 370"] Re: 12v Eco project sound system it was not my intention for a moment to suggest anyone would design us anything 4 free, remember i came here looking for an objective opinion on / alternative to the BF designs. my understanding from the discussions there were that it was feasible to build our own efficient cabs.i do not ever say i try to know better but listen and take on board what u lot say [which is incredibly useful, and i take as being good honest advice, and am thankful for] from the start i hadn't wanted to go the inverter route [as detailed b4-it is not sustainable, we peddle our power and wanted to use it efficiantly not burn it off in loud burst of bass] or else i would have done just this. inverter in to a big old PA. i approached this from a conceptual idea. transference of energy. turning volts into DB most effective and efficiently. to see what we could achieve with this idea [if anything and move on from there] i am coming round to the idea and would even like to 'restore' cabs if it is to do more effective than build then that's the way to go. so new thinking based on ur imput -mini DSP [active] crossover -4x 20w class d/t amps [or even a efficient car amp with built in crossover?] -some old school efficient cabs [ebay etc] could u offer me any pointers on main things to look for? ie. how do i judge sensitivity and efficiency when looking at these things. size is good from what i can tell. bigger horns means more efficient amplification of the sound i produce. ill take some of the names uve mentioned and see what comes up. anything else i should be looking for in an old pa? ive a lot of reading to do with the links ive been sent so ill try and get though some of that now b4 looking. i hope perhaps, at least in part can see my approach as an interesting conundrum. of course there is going to be compromise but i am trying to acknowledge and be considerate of our specific circumstance [12v, outside, renewable energy source] and not mimic a 240v system with 12v. if i can gain the knowledge to buy some old gems i still feel encouraged i can achieve my out come. [i even like that old cabs our still more efficient than todays disposable market. we have a number of engineered components on our structure but sometimes there is nothing to beat an old fashioned lashing. thx y'all [/QUOTE]
