Minimus 77

Just to be certain, the surround kit to get is the 4 1/2 - 4 3/4" one? I found a pair of white Pro77's at GW today. The paint was a lil' rough, one of the grills was pushed in and the foam surround was in good shape. Good shape until one got a little poke when I pulled the woofer :(
I have some poly caps to replace the stock electrolytics and adding some more poly stuffing. That'll have to do until I get time to do the mods. I am thinking of painting them semi-gloss or satin white with tan colored grills :scratch2: . Haven't seen that combo before.
 
More Minimus 77 Redux!

A small dab of glue patched the surround tear while I get the surround kit. In the meantime, I put in those poly caps, the additional poly stuffing and reversed the leads on the tweeter. With just that, the sound is very nice. I like them even better than the Boston HD7's I refoamed recently :music:

I think the woofer used in the 77's is much better than the one used in the 7's. I'll unhook the tweeters and listen to see how the woofers are behaving, but they sound good so far without any kind of network on them.

Another thing I found out is they sound noticeably better with the grills removed! Any other '77 owners out there? Reverse the tweeter leads, leave the grills off and report back on how they sound.

I do like the way they sound, but dammit they're white! Cosmetics relegate them to the deep down under where all backup electronics hide.

White is bad? I have a pair of white Optimus PRO-44XAVs and my wife really appreciates how they match the white furniture in the living room! Much less obvious. If there was a white receiver and CD player she'd like that too, but doesn't mind the Marantz 2226 and black Denon CD player.

Another Minimus 77 guy right here!

Ahem, did you say reverse the leads to the tweeters?? Is that because the stock setup doesn't filter out the highs on the woofer, and comb filtering ensues??

I'm off to do that right now! (and remove the grills)
 
77's time to shine!

The Mini-mi (Minimuses) have a second order crossover on the tweeters with no network on the woofers. This puts the tweeters 180-degrees out of phase with the woofers at the crossover freq. Wiring the tweeters "out-of-phase" is supposed to correct this. I recall reading that long ago but it seems to make sense. I did the same thing years ago with the Pro 7's I had at the time. It's a subtle change, but a free tweak nonetheless.

What I'm really liking about the Pro 77's is that they sound very good with just a re-cap and some additional poly-fill. Added to that is the added bass from the bigger woofer blends with a sub better.

I'm definitely on the lookout for another pair now :D.
 
Just a little paint...

These 77's are definitely keepers :thmbsp:
