I'm trying to build a line array with pvc fence post. One of the drivers I was considering only works well in a HUGE box or as open baffle. If I leave both ends of the post open will the speaker behave as an open baffle? Perhaps drilling holes in the back would succeed in making it more like an open...

Also, how do you find the bass response of your TLAH? Is it strong enough?

Does this mean it's only frequencies that are between the bass and 3500 Hz that are problematic or subject to phase shift & comb filtering?

I watched the video. Sounds good! Couldn't tell which way the taper in the columns was going. It looked like you had the bottom on the ground. Hope that's not where the open end is! I tried mine with the taper & open end going up. Works fine and they're less likely to tip over. My suggestion to ...

I front loaded mine and "sealed" the baffle with gasket material and screws. Works great. My baffle is removable. Are you thinking of permanently attaching the baffle (as in glue)? Could make wiring a blown driver a nightmare...

My TLAH is a bit bright with the piezos. I noticed in my Jack plans that the resistor can be moved to decrease sensitivity by 2 dB. Will this work with the TLAH crossover as well? I realize the two crossovers have different corner frequencies. Also, is there a simple formula for adding resistance to...

Actually I was referring to Chris Allen's work. Is there a link to his Spl charts, etc ?

Forgive me for being new at this. But how do I get to view a particular chart, say a TLAH? I can't seem to find the link to the charts.
