hi all,
i am interested in building an OB using audio nirvana super 3 or fostex fe103en driver. have anybody used this super 3 driver (either OB or closed box)? how does it sound compared to fe103en? fe103en is quite popular in OB speakers. spec wise both are quite comparable.
thanks

i have a 6.5" visaton mid-bass driver which can down to 45Hz in 16 ltr cabinet. also i will be getting a pair of another 6.5" drivers from my friend (dont know the details yet) which he has used in his speakers. i am considering only 6.5" driver for bass because already i have a 16 ltr cabinet with me. want to make use of it. will xover at 250hz or 300hz.
no. bass wont be OB. i want to make use of the cabinet which i am already having. is this kind of speaker build ok? why do u prefer FF85WK over FE103En? do u prefer this over super 3"? i see that super 3" have qts greater than 0.7 so isn't it more suitable of OB?
FF85 sounds better.
If you are going to use a 3" in an OB as a mid-tweeter the cross-over point will be high enuff that the Qt will make little difference.
I haven't heard the AN3.

yes, i just figured out there is no account delete option!
thanks for merging
it makes sense to go for FF85wk as it costs lesser than both fe103en and super 3" drivers. for this driver how much baffle size is suggested? i read baffle size decides how much low freq. a signle full range driver can give. since ff85wk will be used only above 250-300hz, will a smaller baffle size be ok? i am even thinking for just a wooden support for the driver (almost baffle less!) few inches away from the woofer

On an OB, 250-300 Hz is probably too low. To XO that low you'll need to put them in a box.
I'm currently listening to FF85wKeN is uFonkenSET actively XOed (100 Hz) to 2 x 6.5" Mark Audio woofers. Sounds fantastic. I do intend on pushing the XO up from there. In our other FF85 as mid tweeter the boxed enclosures were XOed in the low 300s, in the FF85/Alpha15 MJK OB the HP is closer to 450.

what would be the ideal xover for ff85wk for OB? i wonder if there is any dedicated design software for OB speaker building.
yes. its a hybrid. i have seen Lyrita audio's amity speaker which uses one 6.5" fostex in OB and eminence woofer in enclosed box. i plan to do the same but with different smaller affordable drivers!
MJK's MathCAD worksheets include OB design. See: Quarter Wavelength Loudspeaker Design
Lots of good info there.
Cheers, Jim
