I am talking filling a very large open space with just one speaker playing and no sign of bottoming out!

@Thomas savage is very secretive. I am amazed you manage to shoot a video of him!
port noise/resonance issue is apparent in spectrogram directivity plots in message #1 Very typical for rear ported 2-way speakers, nothing strange.

Any chance that the 700Hz problem is a port resonance? Throwing together a quick model for the DSA135, withthe 1.5" port used in the kit I can get a port resonance in that region if I tune a bit low. Pretty nasty port resonance, though.
Any hardware store will sell runs of foam gasket tape in various density and thickness. Also you can use rope caulk which is very common and often used for this sort of thing. Do not use to thick of foam or to much rope caulk, you will bend the woofer frame trying to compress the material.In the midst of building a pair right now. Great review both showing measurements and how to solve it with EQ! Looking forward to more reviews from the DIY speaker thread
Hmmm... wonder if I should start finding gasket solutions for the woofer to solve the 700hz issue...
thanks for the detailed reply, will check those out for sure!Any hardware store will sell runs of foam gasket tape in various density and thickness.

You can also use a think bead line of quality silicone caulk. Let that dry for awhile (half dry ) and then mount the woofer.
By the way the paper gasket is not that bad and really is prolly not the problem, paper is a great material in certain gasket applications.
The one problem with rope caulk - the oil in it will bleed onto the surrounding baffle over time.thanks for the detailed reply, will check those out for sure!
That doesn't even tell us if you're much of a drinker. For a hundred dollars, if it's PBR in a can they have to carry you out. If your throwing down shots of JW Blue Label, that's a double on the rocks. LOLOnly $100 bucks, my average bar tab, LOL.
My Bassbox Pro model suggests the same port resonance, but even at 10 watts power, the vent velocities are quite low.
