Dan, what am I looking at here? Top is without stuffing, bottom is with? On-axis (color?)+ 8 points off-axis? Just want to be sure.You can see the changes made here by stuffing the ports on this speaker’s big brother (2031P) with cotton balls. I tried this with 5 different speakers, all with the same results.
Top is without stuffing. Bottom is with.
on axis would be the top line and subsequent lines move 11.25 degrees away from the previous line until it reaches the lowest line which is 90 degrees off axis.
I’d personally cross these things over at around 200Hz and position the subs close to them.
Dynamic/power handling.
are those klippel measurements?
anyway, two things:
1. 2030A != 2030P.
2. if you're going to compare something with Amir's Klippel measurements, use the same data display/smoothing/graphing conventions he did.
With these small tweaks the sound was wonderful! I could happily listen to this speaker with EQ as my normal system. Track after track in my reference library sounded great. Female vocals, male vocals, instrumentals, classical, you name it, and it sounded good.
Have you measured your correction? I would not make a bet that your samples are true to the frequency response of amir’s, and one can easily deceive oneself when new speakers sound “great”. Trust me, I listened to many wrong settings on my DSP and found out later.I know this review is ancient ASR history but, based Amir's measurements I hunted down two -- OK, make that *three* -- pairs of these neglected gems to replace 30+-year-old JBL LX22s (driven by a couple of Aiyima A07s sharing a 48V/10A SMPS) I'd been using in the surround/ambience role of my 6.1 near field system. The Behringers were an immediate and obvious improvement, and I couldn't have been happier with what turned out to be significant upgrade.
But wait, the best was yet to come! For months, I'd contemplated digging into them to correct the 800Hz bulge with a notch filter between the crossover and woofer. Fortunately, I dragged my feet on that project long enough for Parts Express to run a great sale on the Dayton Audio DSP-408 -- at only $140 shipped, I figured that thing was a bargain compared to the effort and DIY time involved in modding the speakers. For once I was right -- I programmed the DSP unit to implement (something resembling) Amir's recommended EQ settings and boy howdy, am I now one giddily happy music lover. Thanks, Amir!

It’s easy to check with a gated measurement indoors, done within an hour. Behringer is another word for “get lucky”, especially, when sample to sample variation is important.
