Hi. On the advice of one of the members here, I made some cabinets for these drivers. I used what I had around , and I know the dimensions and the materials could be improved, but it was fun and they sound very good.
I have one good tweeter, so I used the crossover in the CS-51 cabinets that I took them out of on one of the speakers. I think the one without the tweeter sounds better, but I also suspect that the caps are so old in the x-over that I am not hearing it as it should sound.
So what's the next step? Can anyone point me to the optimum OB design for these little 5" drivers? |

Yeah, I've got some old 6" drivers out of a set of giant Sansuis that had originally been sealed (in a can, sorta) midranges. I popped the cans off and they turned out to be really halfway decent FR units with old school AlNiCo magnets. Running sweeps, they only seem to be good to 12kHz or so, but they sound very pleasant and full run just by themselves, so I'm sure you're having the same sort of experience. Probably a good tweeter mated with a good crossover (which, given that most tweeters are probably higher efficiency than your woofers, might just be a very small cap so that they start rolling off up above your hearing threshold so that they're down to an appropriate level when they it the place where these Pios roll off up top) will make the sound better, have more air, but depending on what you've got, may take away from the relaxed sound of just the FR by itself which you are enjoying now.
My advice is to get these things up to hear height. Larger FR units sound much sweeter when you're listening on axis. Another thing you can do, assuming you don't mind getting a bit less bass out of these drivers (running subs, maybe) is to use a narrower baffle. Personally, I'd likely grab like a 1"x6"x4', cut a driver opening in one end and tack some sort of foot on the other and let 'er rip.
If used by themselves like this, they'll be missing some top and bottom, which would make them ideal for either relaxed nearfield listening or use as surrounds in an HT setup, since they should throw a pretty nice soundfield on a narrow baffle.
