narrow vs wide baffle and port location....?

[AudioGeek]

Either I want to go with a narrow baffle width... actually just a little wider than the driver... or a bookshelf style speaker for use with stands.

with the narrow baffle I can get away with a smaller inductor for the rear 0.5

Any other advantages or disadvantages???

Also, I have 2 ports to place, one for each of the driver on front and back.

Should these go right next to the driver?? Or should they be placed near the floor (in the narrow baffle version).

HELP!!!!!

Thanks!!

In the BW where the box dominates (<(2*Fs)/Qes), having the driver near a cab side wall has no effect on it, but if it's used up high enough for eigenmodes to occur, then of course they must be well damped. This damping will acoustically load the driver, which may change its sonic balance. Experimentation with different width/depth aspect ratios and stuffing density is the only way to find out where tonal degradation occurs in this case.

WRT vent placement, the closer they are to the driver, the greater the peaking at Fb, so for smoothest response having them near/at the bottom is usually best. That said, if you prefer the 'west coast sound', place them near/at the driver's centerline like Altec did.

so for a bipole which is better?

a narrow baffle or a wide one?

Thanks!!

Since there's no baffle step due to being bipolar, it doesn't matter.
