Can too low of a frequency damage my speakers?

Now that you've found a tuning/porting that you like for your 604's it might be worth experimenting with porting the center Heathkit cab--maybe install a new back to that center cab with similar slotted ports (but save the original back of course in case you sell those cabs someday)?

You read me well. ; ) that's exactly what I am planning.... if you ever get a chance to try it you should...it sounds so open that way. : )

Run it flat and see if speech improves. The human voice is mid-range, and if you're setting your volume with the treble and bass boosted, you'll be too low in the middle and loose speech.

EQ's will drive you crazy.

I only have it EQ'd like that for older LP formated CD's. New stuff my kids listen to is pretty much flat, and watching that movie was also flat. I guess I will have to try a frown

EQ shape.

Being a Dub owner and lover....why would you ever do that to your Dub....: / I'm not running that through my 50 year old Altecs to see if they'll survive. I love them too much to put them through that. Awesome video though.

I like my bass too, If it's clean.

BTW a tin can makes for the worst speaker cabinet.

you don't have to turn it All The Way Up.

Don't remember the exact year or place, but it could have been in 67 or 68 that one of the bigger HiFi shops between Boston & Cambridge had a display of what had to be an acoustic suspension woofer of about the 12" variety. This was connected to an amp of sufficient power and of such a frequency that the woofer went about its business going to near maximum excursion all day long. It appeared to me moving somewhere about 3/4 to 1 inch total. Didn't make a sound, but looked to be in the 2 to 3 hz range. Also don't know if the voice coil was beefed up to handle that duty. It was interesting to watch. Didn't laugh about it, unlike Howard Stern's speaker "test" in "Private Parts."
