Wolfhorn SDX Design Finished - Page 12

I am not so sane myself and am afraid of a possible back feed that would nuke your brain.eek.gif

I really should give it a try, but I lack so much of the other related knowledge that adds to the steep curve, not to mention lack of time to devote as well.

I am glad there are folks like you that don't mind sharing.wink.gif

I am not sure any of us on this board are completely sane. smile.gif "Normal" people think a single 12" sub is overkill and 15" drivers in speakers a luditte failure to understand the bass/mid capabilities of modern 5" drivers that can be sourced from China for $3.

Note: I am not a clinical psychologist, psychiatrist, and did not stay in a Holiday Inn Express last night (no big western chain hotels exist in Cambodia, better come for a visit soon - a Hyatt will be openning soon to destroy the charm of lodging options in the developing world).

Minor update. I now have a Radio Shack SPL meter freshly Wallins modded. Here's a few sweeps of both my horns in room. The louder ones had stuff rattling in room - keep that in mind. Could use some EQ over and above the nothing I'm getting from the Reckhorn B-2, so I am going MiniDSP at last.

Most dips are no surprise to me. What is a surprise is the relatively decent extension to 130Hz or so, and the big peak at 15Hz (which by the way I love). I've still got these beasts crossed at 80Hz, so I'm leaving a lot on the table above that it seems.

Remember, only one horn is the SDX design - the other is the dual Tang Band, which still sounds too good to knock down and replace with another SDX unit. It would just be a waste of wood to kill it.



And with the B-2's measured response added:



All captures done with the Behringer UCA222.

Nice Wolf.

Let the tweaking begin!

Added the Sundown E-10 D2 to the list of driver alternates. As always, I have not verified its compatibility firsthand, so go with it at your own risk.

Models about as well as the TC Epic 10 does, assuming published specs are accurate. The driver really wants a smaller design, but should work well enough if the SDX10 isn't available at the time you're reading this.

Thanks to the addition of a tool in Hornresp to simulate filtering, I am now recommending a 14Hz 48db/octave highpass for this design using a MiniDSP. Allows one to get the absolute most out of the horn without too much pesky distortion caused by operating too far below the corner. Should just about eliminate the chance of bottoming out the drivers, too.

Nice, every tidbit of info helps those considering the design. smile.gif

Thanks for posting the update(s).

You're welcome biggrin.gif

I was hoping to update with the results of getting the MiniDSP set up, but I don't even have it yet. Had too many financial setbacks this month. I'll be going with the balanced version due to the fact that I'm running a pro amp.
