MMC650 enclosure

getwired

I realize this is not an ideal situation but I want to make home tower speakers from some left over Polk MMC650's that I have. I have attempted some enclosures previously for these speakers. The enclosure was roughly 8"x8"x36", sealed using 3/4" mdf. The sound was good from probably 200 Hz and up but the low end was non-existent.

I know there are factors that are fighting me to make this sound good. The biggest is that the efficiency of a car speaker is horrible compared to a home speaker. I don't really know why but the woofer barely moves hooked up to my 100 watt home receiver yet moves much more on a 22 watt car deck. Why is that? Also this is a free air speaker so I know that is a factor but even a free air speaker sounds better with an enclosure even if it's a very big one. Right?

If anyone knows how to make these sound good as home speakers please help me out.

I have extensive woodworking ability so enclosures with multiple chambers and venting or porting is not a problem.

if the receiver is a surround sound receiver I would check the crossover settings. Also might want to double check the crossovers in the speakers and make sure all is hooked up to the right spots. I once wire a set up in a hurry, had all of my leads going to the crossover accidentally hooked the input leads to the woofer, and the input (from the amp) to the woofer input. I kept scratching my head, because I knew it was not right. I had to turn the volume way up to get sound, and the bass was just not there. It sounded exactly the way you explained in your situation

Thanks for the responce,
My reciever is set to large fronts, all other outputs off. The crossovers have leads that are sized so you can only hook them up one way.

getwired,
Have you made the tower speakers from your mmc650? If you are not using them would you be open to selling them? If so, I'd like to buy them from you.
