Rite ive got the following system in a classic mini:

Front: DLS B5 comps 60-18khz or PG QX130 comps 85-24khz
Rear: PG 6" 75-20khz
Boot: Diamond audio 10" sub 28-250hz

My Q is before taking into account filter etc.. which comps would work better for sq?
im trying to get:
infront=vocals /slight midbass
rear= Midbass
boot=bass
Or is this a bad idea? If this is how I should have it then would the DLS comps sound a bit odd as they are in the front but drop lower and don't go as high as the rear speakers?

i would say go for speakers with higher frequencies in the front and then the lower frequencies in the back, i could be wrong though.

[Bungle]

that sounds right to me :smartass:

yeah my thinking been the higher more directional speakers in the front and as u go back over, it drops down to the lower less directional freq's.

Thats all good until you have someone sat in the back who can only hear the bass line to all the songs...

This is how my car is set up and it sounds naff in the back seat. And I mean REALLY naff.

Ive got:

4" Pioneer 2way speakers in the front
6x9" 4way speakers under the rear bench
12" Sub in the boot...

Sounds ok til you climb in the back! :nugget:

Right, DLS are much better SQ and go for those in front. Obviously don't expect them to play below 100hz much.
Midbass is still directional so sticking them in the back would cause staging problems. Incidentally those DLS's should play down to 100hz and so will meet the subwoofer, no need for 6" midbasses at all (and if you do use them, you'll need an extremely sophisticated amp that has bandpass filters on it (cuts both low and high frequencies on the same channel).

Also if you stick the rear speakers on the shelf, you'll need to build airtight boxes around them below the shelf since if you don't the sub will literally rip them apart. Building boxes means the enclosure will be smaller than the boot obviously, so now your rear speakers' lower frequencies are effectively dimmed! Hence defying the point of midbass.

Stick those DLS in the front (if you want some more midbass, get 6" comps of the same series), sub in the boot with some holes made in the shelf (and put a grille over them to look pretty).
Then if you're desperate for rear fill, stick in some coaxials under the rear seats (e.g. 6x9s or 6" coaxs), powered from the head unit. Once you get some friends in the backseat who won't care about SQ, simply turn the Fader on your HQ to switch them on.

Also set your filters with the DLS's around 110-100hz (and the same with the sub). Ideally you don't want it higher than 100hz, but if the speakers have some trouble playing so low you'll have problems at the meeting point with the sub. Basically with these you can experiment there and then!
