What is really dissapointing in regards to line array design is that the market really does lack a variety of good tweeter
candidates in the lower price range. There is nothing
really wrong with the BG products for making a line array,
but their lineup doesn't offer anything really amazing that
can show people what a really good line array can do.
People who build these array won't realize the full potential
of a line array unless they migrate to the more expensive tweeters. That is the problem as I see it right now.
The Neo8 isn't a great tweeter, in spite that line arrays
have been built using them and people love the results.
They love it, maybe because there is no other speaker used
for comparison. If you love Taco Bell but never went to Mexico for food, then you will be missing out too.
I wonder if the Dayton RS series is in the same league as the Vifa PLs. From the reviews I've read they seem to be very nice drivers but I haven't heard them yet... Any opinions out there?
I maintain a certain position on line arrays, the tweeter
is the most important variable because the market lacks
choices, therefore redirect the big money towards this first,
the remaining of the funds use it for midwoofers, even if
they are low in cost. The reason for this is; If you build a
massive project like this, one should go with active electronics and multichannels of amplification. Second,
in an array, even cheap midwoofers can do amazing things
in large numbers, but the ribbon/planar tweeters pose
more of a bottleneck in performance. If money is no object,
then spend the extra money on expensive midwoofers if
you want, but it's not mandatory.
Dayton RS or Vifa PL, using that DCX with 8th order
crossover, it wouldn't matter much to me on which one
to use, I would look for a better tweeter solution first
then analyze the midwoofers later. If your tweeter array
can be crossed over lower, lets say in the 1500hz - 2000hz
range, 4th - 8th order, practically any brand of decent midwoofer can do the job. If this was a 1st - 2nd order
crossover, passive or active, then I probably would avoid
exotic cone materials [metal, etc] as the ringing may annoy you.
