Any luck with 6x8 car speakers?

johnr66 · 02:27 PM

I was thinking of making a pair of portable speakers using 6x8 speakers (kind with the built in coax tweeter). Problem is, there are no T/S parameters published for several I looked at. Has anyone played around with an enclosure for these? What works usually works better? sealed, ported? Box size?

I was looking at the basic Pioneers or some other budget brands. I guess they are all about the same.

Thanks for any help!

Most 6x8 or 6x9 are infinite baffle type as they were designed to mount to a parcel shelf in a trunk so putting them in a box tends to make the upper mid bass/lower midrange peak and that doesn't sound very good. If you want to put them in a box then try a ported design. A real large box would be best but then that doesn't become very portable.

Small open backed box might do it, but bass wouldn't be brilliant...

Thanks guys. I'll probably scratch that plan. I'll probably go back to a two way layout. What I need is something with 4 ohms, around 92db 1w/1m. 8 Ohms okay if efficiency is 93db or better. 6-1/5" woofer. It would be used for anything in the range of .5 watt to 20 watts. Box no larger than .8 cu ft. Not too pricey.

Edit: A full range is still good if the highs are crisp.
