Way to get moving on things 2bigears. Some say MMG's are the some of best $500 (new) you can spend in audio. They are like that cracked window, letting in a breath of fresh air but of course you want to open the window more and well you know what happens next.
I still miss my MMG's and 1.6's, many times I say from a simple music enjoyment standpoint I could have been happy there, especially now that there are deep bass solutions. Of course they have their limitations but... Let me tell you the glory I hear from my friend's treaked 20's is mesmerizing. Like swimming in an ocean of sonic waves and then coming home to your pool.
At any rate, if you can swing the 1.6's I'd say go for it. All I can say is given room to breathe, they are so enchanting, they don't do it all but they know their strengths and play to them. For me, one of those speakers that make you forget the checklist and just enjoy what this baby is all about. You may not marry her, but years will go by and you say I should have, I should have kept that magic in my life because that's what makes me feel more alive. Yeah, my honey now works, cooks, cleans and take good care of the kiddies but she doesn't have that...Mmmm. And many men leave and find Maggie again and say I should have never left you baby, you were what I wanted all along but I just needed to wander to find my way home. "Mama may have, Papa may have, but...
Here's a pic of my xover mods, 1st in the experimental phase and then the final product. I was set to sorta Gunn them up when another temptation game knocking. "I'm on my way, home sweet home." If I ever find a place where Maggie and I can live together happily. Maggie don't know about my stacked Quad affair, shhh...Electric Ladyland.
