full range without whizzer cone

NED 209 · 8th January 2008, 03:28 PM

hi guys, im looking for an 8" full range driver, preferably with decent efficiency, that i can put a chrome dust cap on. bit of an odd request maybe but its for a particular application. it doesnt have to sound amazing, just good.

any ideas?

It's likely that the metallic dust cap will resonante badly, colouring the sound of any driver you fit it to.

Two modestly priced units that spring to mind are the Visaton B200 and the Fostex FF225K. The latter however is a WR unit, not an FR, with very limited excursion, so you'd need to horn load it, and add a tweeter. Q on the B200 is high, but it can be used in a variety of ways if you're careful enough.

Fostex F200A would be ideal, but at a cost....

i have the B200's, very expensive and i couldnt make myself fit dustcaps to them. the fostex look gorgeous but i imagine they weigh a ton (portable project) and cost a lot, the bogens are deff the favorite at this stage. cheap, light and hopefully cheerful

thanks for your reply's, interested in more if ye got them

if you just spray painted it with metallic spray paint...could you use one with a whizzer cone?

Whatever you do don't spraypaint a fostex 206 or 207.
the centre of the dustcap is ventilated. Both of these are rather heavy too.

It's a pity car audio doesn't go up to 8 inch.

Is this for a ghetto blaster project? You could conceal tweeters where the recording microphones go and use a non fullranger or support a fake dustcap in mid air from the back of the grille.

The B20 does have a whizzer and not very good efficiency, probably still your best bet. salvage a plastic chrome dustcap off some junk drivers.

You won't find much, 8 inches is a bit big for a fullranger even with a whizzer. 6 or 6.5 inches would open up a lot of options.

I assumed that you would be willing to cut the whizzer and add the phase plug
