DIY Fostex FX120 and Coral Flat-6B Bass Reflex Speakers

DIY Bass Reflex Speakers. The larger speakers are 6.5"-7" (depending on how you measure them) Coral Flat-6B's. The build cost for them where about 2/3's that of my Fostex FX120 Speakers. I am going to dampen the stamped Coral frames some day, just to hear if it makes a difference. But so far I have nothing but praise left for these old drivers. They are 20+ years old, but they still kick ass.
