[burmeister]

hi,

would like to ask if anyone has cabinet/enclosure details and pics for fostex fe203? nearest one i got is fe203 en-s.
also thinking if it it would be good for open baffle.

appreciate for any input/s.

thanks🙏

Don't know of any specific designs, but these specs imply that they come closest to Rutcho's FP-203 specs: FOSTEX FE203の仕様 フォステクス

Lacking any more information/measured specs, his 'universal' BLH is probably your best overall option short of measuring your own driver's T/S specs:

Fostex FP-203 Fullrange Loudspeaker Measurements Data and Information Full Range

Rutcho's Universal Backloaded horn for different 8-inch fullrange drivers

Fostex FE-203 1984 (y/final production)
Fostex FE-203Z 1988 (y/final production)
Physical Compatibility/Similar sound characteristics:
FE206E yes/no (FE-203 1984)
FE207E yes/yes (FE-203 1984)
FE206E yes/yes (FE-203Z 1988)

OB no. ONLY BHorn.
If doing a BR type you risk losing your low end under 60Hz (option of adding a subwoofer to reproduce the lowest frequencies) for not using the backloaded horn.

Thanks! Good to know, couldn't find anything re sound.

noted on this. part of the plan for OB was to put LF drivers.

- should work well in a Karlson K12 - again no "low" bass but will have power in its range.
