The only reason you would want SPL is if you were looking to go deaf quickly perhaps if your wife was annoying you, but other than that I don't see the point. I'm not that knowledgeable on audio, only have a basic understanding but I managed to put a pretty good system together. Although I do need a tuned sub box, which are pretty expensive unless you know where to get one on the cheap! All I know is when I get more cash I'll be upgrading to a higher model of focals, they don't even compare to brand new speakers in brand new cars on the market. Just amazing.
That's pretty brave saying I have a good taste in music not knowing what I listen to haha, dem focals play da wobblez of my dubstep tunes hella nicely aye
If you like i'll measure my sub box and give you the dimensions... this box and ZR musicmax (which i got 4 $55 at Bunbury Cash Generator) is an amazing combo... i've had all sorts of subs in that box and it makes everything sound good... the only sub i have had that i reckon was better was 2 image dynamic 12" in a sealed box... it was deep and musical... so is this ZR... the box is made of 32mm marine ply and lined in velvet with tontine pillow fabric in the back... its a beast! but amazing! and not too big too... which is important for me with my camera gear...
