Do you want bass that is way tighter, cleaner, fuller, more dynamic and more pure? If so, then you need to damp the frame of the Alpha with EAR SD40AL and magnet brace the woofer. You get 13 ply birch plywood and make the brace out of two thicknesses (1.5 inch thick) and at least 2 or three inches the other direction. You epoxy a piece of the same plywood onto the magnet of the woofer but make sure it overlaps on the bottom and top a bit so you can drill some holes there as you are going to bolt this epoxied plywood to the brace. This way, you can always remove the woofer if you blow one. Total crazies can just epoxy the brace right to the magnets. This brace would be bolted to the magnet and then epoxied and screwed to the top and bottom of the inside of the H-frame. Look out world, here comes bass!
Do you want way more midrange transparency and purity and speed. Well, do the same as you did for the woofer but to the Tangband. Attach the brace to the back of the magnet the same way, curve it around so it attaches to the baffle above the tangband and also attach it to the base. Wowie Zowie....mindblowing sound.
Of course you want to get rid of your binding posts.....they suck big time...as well as any connectors on your speaker wires. Simply solder your speaker wires directly to the drivers with no other wire in between. Please solder directly on the eyelet to the wire coming from the voice coil and not to the other end of the solder tab. You will not burn the voice coil as long as you do it with a hot iron and fast. You can heatsink the lead out wires to the coil if you are a timid type.
But maybe you like the sound of resonating woofer frames, resonating woofer and midrange magnets, thin resonating midrange baffles and veiling connectors. I don't. For a couple hundred $s you are in a whole nuther league of goose bump city!
