You may laugh, and you most certainly will feel my pain.
I made noise, but it was very, VERY short-lived and I'm still scratching my head/sick to my stomach at the wake of disaster my little experiment brought. Don't really think I did anything really that wrong, but a combination of misfortunate events blew up my amplifier, my left front BW801, and possibly one of my horns.
Let's see, what all happened!
We finished building the horns on Thursday and were in the process of finishing them on the back deck Friday so I figured what the heck, let's make these things move! So, I grabbed a 30 foot wire, plugged it into the outlet of my front left speaker and fired up REW to send a 30 Hz tone. Now I knew I needed to be super careful because I was running these through a full range channel with no highpass filter so I figured I'd just keep it simple and test out a few 23-80 Hz tones. So I fired it up, ran a few sweeps, and gradually increased the volume while I kept an eye on the driver. It was amazing how much volume it was putting out with very little driver movement. Figured I'd drop down a few hertz and find the low-frequency knee. At this point I was pushing things a little harder, but still not too crazy, and then I heard a loud click and no sound. Went back to my amplifier and noticed it was in protect mode, figured no biggie, and turned the tone off, turned my amplifier back on only to hear a real low 60 Hz hum and it went into protect mode again. Things started smelling funny outside, so I figured **** somehow I’d blown the sub. So, freaking out I unhooked the amplifier from the sub, rewired it to my left 801 and turned my amplifier back on to figure out if I'd blown the sub or not only to hear that same 60 Hz hum through my front left speaker and find my amplifier going into protect mode. Well crap, looks like I just blew up my amplifier. Only thing I can fathom is when I was playing the test tones the 4 ohm impedance of the subwoofer dropped down enough to be more than my amplifier could handle and instead of going into protect mode it just blew the hell up. Then, me being stupid and wiring my 801 back into it blew up the base driver in my 801 (at least I hope that's all it did).
Still trying to figure out how the heck this all happened. I mean my Emotiva amp should be able to play that sub at moderate volumes without blowing up right?
Now I need to find another amp to test my horn and make sure it's okay, must say I'm a little bit gun shy to use my Emotiva amp after what I just experienced.
Oh well, screw it :-) they're pretty dang impressive!
