I made in DIY a configuration: FE 166 E out of plane baffle (55cm top + 32 cm broad and 23 cm of depth) + Passive box Audax PR 240 M6 in bass reflex 70 liters, event of 7cm of diameter and 9.5 cm of depth.
My two problems:
Audax is completely in withdrawal because of its lack of output and traine. Fostex is not exceptional. Depth and dynamics misses? Crossover not adapted, size of the baffle plan??
could you help me in order to find solutions (new filter, size of baffle plan ...)
A couple of questions. Are you using the FE166 as a midrange/tweeter? If so, I've found the fostex a little lacking in the high end in spite of their specs. Try adding a KSN1038. No idea what's up with the Audax. I assume you've matched the drivers for efficiency. The fostex I have are around 93-95db/W. Chris
Hi, The KSN1038 is the piezo tweeter Wayne uses in the smaller Pi speakers. I've used them in a few speakers and they work well. As for the audax, you'd have to run the T/S parameters through pialign or another speaker box program to tell if you got close on the box size. I didn't look up the FE166, but most of the Fostex line near that numerically are around 95dB/W while the Audax that are in the Parts Express catalog are around 90dB/W. What that means is that the woofer is going sound really quiet. The effeciency numbers for all the drivers have to be within maybe 1dB, or you'll have to pad down the mroe efficient driver(s). Chris
