Folks, ntrain sings the same tune in every thread, so please do not feed his necessity to take this thread off topic. His claims are always unfounded and he never provides proof, so lets just ignore him. Do a search on his posts if you want proof of what his agenda is.
My agenda? Please, if people do a search, they will see you and a select few others(always the same ones) who have issues when people like myself do not agree or compliment your own posts. You along with a few others have a problem with your own views being questioned and debated.
I don't need to tell others to ignore you, or make childish remarks because of opposing views. WHat does that tell you? Time to grow up a bit.
Regardless Im going to highly debate your argument above the childish paragraph at the bottom.
Your right an "EQ" specifically cannot fix poor xovers, phase/time alignment issues, cabinet resonances etc........but that doesnt mean a speaker cannot be fixed.
This is where for a example a product like the DCX2496 comes into play as an example. Its not just an "EQ", its also an infinitely adjustable xover, 3 way time delay processor, with 6 section parametric EQ.
OK, so have a speaker with a bad passive xover? One that also has time/phase dealy issues? Maybe some "cabinet" resonances etc?
Easy fixes, especially if your not all THUMBS(or narrowminded for that matter).
To take care of the bad passive xover......first thing is first.....REMOVE it altogether! Not exactly a hard job. In one swoop you can take care of the poor passive xover, phase/time alignment issues by simply BYPASSING the pass xover altogether(Its what I did on a few pairs of my speakers). RUn the speaker fully active.
Oh but the cabinet of the speaker "resonates".......OK will then, get your DIY gloves back on and reinforce the cabinet. Using DIY cascading bracing, resin, ACE, multi layered damping materials, you can easily and cheaply reinforce the cabinet to completely reduce unwanted cabinet resonances. Again this isnt a hard job to do, nor is it expensive either. Most cabinets are made with minimal bracing and damping materials, its not too hard to modify the inside of a speaker cabinet if it resonates where it actually affects the sound of the speaker.
So lets see, we started off with a speaker with nasty cabinet resonances, a poor passive xover with potentially mismatched drivers. So we have reinforced the cabinet via DIY mods, and removed the passive xover. And for sh!ts and gigles, lets say we also got rid of those cheap plastic binding posts with some nice Cardas units as well......
So, now since your running the speaker fully active, your able to:
A. Level set each individual driver relative to the others both L&R
B. Set each individual xover point and slope for each individual driver
C. Correctly setup phase and time alignment for each individual driver relative to the listening area
D. Individually EQ each driver to the rooms natural accoustics at the listening area.
So we took a "flawed" poorly designed passive speaker, and significantly improved it. We got rid of the poor passive xover, beefed up the bracing of the cabinet to remove the nasty resonance it had, and optimally set up the individual levels,xover points and slopes of each driver,properly set up phase and time alignment, and then EQ'd out each driver to the rooms natural accoustical properties at the listening area...........
So yes, a flawed speaker CAN be "fixed" in reality. This can be done with pretty much any speaker on the market. If you doubt this or question this, then its time for you to start perusing the DIY sections on this and other AV forums.
