    By the end of the night, we were down to a few of us, at that point we had moved the speakers at least a dozen feet off the back wall and about a dozen feet apart we sat maybe 10 feet back from the speakers.... turned the light off so it was pitch dark, cranked it up the speakers sonically disappeared. Was it really shocking or were we just drunk and tired ;)  I think it was real


    I remember Trey shouting, “You should see how bad the group delay is on those things.”

     

    ”Good sir, we do not give two &!$@!”

  2. It’s not the crossover, because if it was, neither of your woofers would be working. So, it’s either damage to the driver, or your little buddy chewed through some wiring. 
     

    Use a Torx bit #20 to remove the screws to the back plate. Inspect the network and the wiring. With a good flashlight, you can inspect the wiring through the rear. 
     

    Same Torx bit for the woofer. Avoid power tools and take your time. Once you get the woofer out, put a meter to it. 
     

    Funny thread, do some people actually not know there is only one “deang”?

    On used original commercial units redeployed to home use.
     

    Commercial plywood LaScalas had commercial woofers with higher SPLs and were often deployed in harsh environments, auditoriums with high temperature and humidity swings over many years. It’s fantastic people find them so good for reuse.  
     

    Before you go screw up a pair of AL5s which are MDF/HDF and therefore have different resonance characteristics, I’d consider your SPLs and real world use and actual audible measurements from listening position.  Should be easily done with test tone and mic, to pick up actual signal mismatch and with someone alternately pressing on sidewall to dampen to see if errant signal reduces or goes away.  Probably REW can do it.

    Along with the MDF, quite a bit of correction built into the new networks.

     … it’s the arrival time of the same frequency from two locations that can either amplify or cancel.  


    How can it amplify (sum). I thought it was out of phase wave cancellation? That’s why the response looks like a comb. I don’t see how this could ever be a good thing. 

  5. If your plan is to gut them, the cabinets would be practically worthless. I can’t imagine anyone paying for them with no drivers or crossovers. 
     

    if you are tight with money, the answer is definitely not destroying a perfectly good set of loudspeakers. 

     

    They were designed to be used as stage monitors and have a strong vocal presence. Converting the networks to the AA will rebalance the loudspeakers. It will pull the midrange back so you can hear the bass.

  6. I think we should leave any enforcement of the rules to the moderators. 

     

    We should always be interested in helping somebody figure out a problem. It’s not like he’s here shilling.

     

    The sound you are describing is what one might hear with no tweeters, yet you said you changed the diaphragms out. You should start by double-checking that they are actually working.
