Damn I fell like tooting my own horn in this thread and it crossed my mind that marcsrollin might toot my horn as well (
no pun intended ), but I've been doing this sh!t for
way too long.
Keep the project going!
The 6 X 9's are full range right? Playing all of the "musical notes" right? It would be better if there was a divider between the left and right speakers, but I wouldn't ditch the current project due to a lack of a divider. The sound will be more "muddier" due to the lack of a divider. The left and right speakers will "fight each other" due to the lack of a divider. The "fighting" will shorten the life span of the speakers but not so much to ditch the project, negligable (sp?) at best.
Fiberglass is used for sound deadoning. Fiberglass is used for insulation (heat, sound, whatever, etc...). There is absolutely no reason to add Dynamat to any fiberglass enclosure. Ever.
This is of course assuming that the enclosure itself is of sound design and thick enough to not flex under the power given to the speaker.In mounting the speakers to the fiberglassed/resined MDF use the coursest (sp?) screw thread you can find. If the MDF happens to strip out, replacing the MDF will not be an option.
About 30 or 40 years ago speaker manufacturers would add fiberglass (similar to house insulation) to their speaker enclosures to get a increase of bass response. The more modern manner to do the same thing is to use synthetic pillow stuffing. Ironically, the sole reason the insulation worked in the first place, to improve bass response, was because the design of the enclosures was too small for the speakers.
Lastly, music has changed. Big time. When I'm writing about left and right speakers "fighting each other" most of the current music today is not as "stereo" as it was back in the day. My fav band, the original Van Halen, would have Eddie coming out of the right speaker, Alex and Michael Anothony coming out of the laft speaker, and David Lee Roth spitting out of both speakers, now
that is stereo seperation. Not so much today. Also a lot of todays stereo seperation is purely for hmmm... impact. You'll have a jammin' almost non-stereo seperated session go to silence and then the lead singer come in with lyrics and then have the recording immediately go into a non-stereo seperated recording.
A lot of this sh!t is theory. I will never forget the lesson I got in a "long port". But that's a long story, maybe another time.
Damn, I need a drink.
