2001 Space Odyssey BiBs

[ajh]

Is there any sonic benefit to mounting the driver on the wide side of the box rather than the narrow side?

Does a wider baffle sound better? Reduce baffle step?

If so, what about the back wave hitting a parallel wall as opposed to the slanted baffle? Will this cause reflections through the speaker?

I think I am finally going to get to build some BiBs and planning on 8" Fostex units. How do I decide between the 206 and 207?

Big thanks to all of you who have contributed to the DIY/FullRange community.

That wasn't a consideration.

No such thing as 'better.' Different, yes.

Reduce baffle step?

It should push it low enough for it to blend into the room's / horn's gain BW, but it's rarely an issue with these enclosures anyway.

It should be lined, so that shouldn't be an issue whichever configuration you go with.

Inclination. The 206 gets up higher by itself, but has some midband peaking. The 207 is a little flatter & rolls off earlier, so if you want the extreme top end, you'll need a supertweeter.

Are you going to build the 2001 BIB?

>>> Does a wider baffle sound better?

I played with wings a little bit and find the lower midrange sounds different, maybe fuller... maybe more muffled, with a wider baffle. I am using the Fostex 165k. Results may be different with other drivers. IMO wings are not needed but fun to play around with if you're curious.

>>> How do I decide between the 206 and 207?

Good question. I never heard either but understand the 206e sounds brighter. I know people who have used both in BIBs and always seem to really love them. I would be inclined to add a super tweeter on the 207e... which is the one i would choose if it were me. I would choose the 207e because i think it is a more flexible driver to use in other box types than the 206e and i have a tendency to swap drivers around.

Keep us posted on your BIB!

I'm not sure. I thought that I had read some opinions that wider baffles were better in some respects - I think in relation to Pawo?

Anyway, I might do it just to be different but I am a little worried about the "fuller/muddier" impression.

Are you still taking pics for your site Godzilla?

Thanks for your direct and helpful responses guys. Not sure when I'll get started, but the sooner the better.
