ha, ive not really looked at it yet.. ive been lost in a world of different amp types and chip selections.. trying to find the best choices within my budget.. there are so many choices and opinions.

ive also just found the 50% discount code for the new TI class d boards..
TI Class D EVM Board 50% Promotion

which has thrown a massive spanner in the works, as they are supposed to be excellent.

im now thinking of buying two of the 3255 boards. they will do 315w into 4 ohms (admittedly with 10%thd) but i doubt i would ever go that loud.

i also assume on a 16 ohm load (the alpairs in series) they will provide a generous but reasonable power level there too.

advantage is the two amps will be identical, meaning same voltage requirements - one big psu for both - cost and space in case saved.

also, as mentioned they are supposed to be great.

wrt the EQ trick.. im not sure i follow completely.. unless you are referring to looking at the graphs for the types of music i like and estimating the area under the graph on either side of the crossover point to see what proportion of the power is required for each "half" ..?

ok so i just thought id write a quick follow up, now the project is finished and providing my daily sounds.

it was a mammoth undertaking, and grew from a single subwoofer to a full on dual sub, dual fullrange system with a 6 channel minidsp powered amp. it took over a year to complete.

massive thanks to everyone who helped me, and apologies to anyone i bugged too much. i learned a MASSIVE amount about everything from woodworking, to circuit simulation, to heatpipe use.

there are about 2 dozen threads ive started over the last year covering every aspect of the project, so i wont link them all here.. instead ill just post some (bad) photos:
