Hi,
I have crossovers done, no new baffles yet. Check this RTA. I had a hole around 2 or 2.5 kHz, reversing polarity only moved it down to 1.5 or so, and looked worse, so I kept designed polarity and moved the waveguide. This is the best I got so far, about 2 inches out from front of current baffle. Given that the JBL 123A-1 has a shallow depth, does this seem reasonable? I estimate that the voice coil of the Selenium is now approx. 2 3/4" back from the baffle.
This is somewhat critical because if I am to keep this physical arrangement, I won't mount the waveguides in the new baffles. I'll have to keep them on top.
Ideas, suggestions???
:scratch2:
Wow, something looks seriously wrong. The photo showing the Selenium back of the baffle looks to be a bolt on unit, rather than a screw mounted. Is this the correct Selenium and waveguide?
Edit: I have gone back through the past few pages of posts, and see that you ordered parts for the low SPL version of woofers. Is it wired correctly? The RTA FR shows something terribly wrong. The waveguide shouldn't have to go so far ahead of the baffle to make the EconoWave work. Maybe Zilch has some ideas as well.
