Default ideal baffle/enclosure shape for OB?

Is there an ideal speaker shape for an open baffle/cardiod speaker? I will be fibreglassing an enclosure soon so I can make spheres, curves, etc. I was thinking of making a flat front baffle, a half sphere on the back.

What shape would be ideal for baffle diffraction?

Ans: No. It is driver/system dependent. Many Variables.

Ans: Diffraction is mainly a tweeter issue. The least of your concerns when trying to come up with a baffle shape for you midbass!
Suggestions: Research 1st. The bible for OB.

Make a narrow baffle with wood to mount your drivers, then add cardboard to get your desired shape. Measure. Measure some more. Listen. Build. Measure again. Listen. Enjoy .

Cheers,

AJ

Would nearfield measuring be sufficient? I have a small apartment and no room to do an accurate farfield measurement.


Thanks
Alex

Don't waste your time with nearfield measurement with OB and far field measurements could be just as misleading. Measure at listening position using your anticipated speaker placement. That's all that matters anyway.

Thanks for the input John, however, that is not an option. I will be moving in 3 months and will probably move 4-5 times in the next couple of years. I need my speakers to sound good whereever they are... Could a far field measurement be done in an apartment, or would room acoustics cause too much error?

Thanks
