You know, before I ever heard of doing this type of thing ... even before I heard of DW Woofers ... I had a dream that I invented something like this. It was a light weight contraption which was cardiod shaped, with a handle on the top. You just sat it infront of the kick drum as an extension. I told this to someone and they proceeded to tell me that DW had the woofer thing happening. Guess I was too late. The idea must have been floating around and eventually got to me about a year or so too late to be the first.  On another note ... slightly off topic ... I've been thinking that maybe I should include some of this Physics of Music stuff in the VIP Room. Things like terms, definitions, theory explanations, etc. I probably should get too heavy on the stuff ... but think it's really good to know the basics. It sure makes you more valuable as a player because you can bring more to the table. The downside ... your bandmates may try to dump all the PA responsibilities onto you! Thoughts?

back in 1972 a guitar player friend of mine wanted me to play conga while he and his drummer jammed. that conga couldn't cut through his huge amp and the drums(trixon; the cone shaped ones).he took a small stereo speaker, sat the conga on top of it and said that it would act as a mic. can't remember what amp he ran it through,but it worked well enough to be heard. it wasn't a full clear sound, but it was a neat trick. I may be odd, but I kind of liked those trixons, and they're quite collectable now.

hmmm ... (gears turning) ... I might actually build a kick "subwoofer" mic cabinet combining that idea with another ... bear with me here.
build an 18x18 square cabinet about 16" deep with a closed back. have a 12" (maybe 15?) speaker mounted in the center wired to an xlr jack in back. on the top and two sides of the cabinet have "flaps" that can fold back and out of the way or forward to essentially extend the speaker cabinet out toward the front of the kick while keeping the speaker far enough away. this would help isolate the kick sound and focus it in on the speaker thats going to be picking up the sound. kinda like having a chair in front of the kick and laying a blanket over the chair and drum.
(drools)
Mark - This sounds cool, but you may not need to do anything to help isolate the sound. This was NOT a terribly sensitive microphone - it seemed to react only to very blatant (for lack of better word) stimulus: I.e. my kick drum being played hard, with a large hole in the front head to further assist the projection. That was pretty much all this speaker could "hear." It makes a VERY directional mic. Definitely not an omni! When we went into the control room and solo'd that mic, all you could really hear was the bass drum. There was nowhere near the level of bleed from the other components of the kit that conventional mics produce. The downside of your idea is that it might muffle the acoustic sound of the drum in that room - which is a bad thing if you're using any room mics.

hey acro ... its all about options. hinged flaps, use 'em or dont. when I record drums and upright bass together in one small living room I NEED some isolation or itll all be drums with a little slap here and there  if im recording drums alone, ill probably only use room mics.

Great thread! And thanks for the tip Mr. A.
Interesting that so many great ideas seem so obvious in retrospect.
I think the great advantage you're going to have with something like this is in the mixing stage. How many times have you recorded a kick and the character was all wrong for the song - too much bass, or too much midrange, wrong sound, etc? With this method, you could blend the two signals in relation to the song.
I think this is one reason you see a lot more experimenting with plug-ins on drum tracks these days. Tweaking kick tracks in the mixing stage was previously limited to compression and EQ. But Amp Farm is a common practice now in order to give the kit more muscle. Engineers often throw it on kick drum for the very same reasons explained here.
My question still (unless it was already addressed and I missed it) is: Is the amp turned on or not?

The amp is off Side. You are only using the speaker from the amp.

What he was doing was creating a down home passive radiator.
In some speakers, a passive radiator is used instead of a port, or hole in the cabinet, to increase the depth of the bass response. It's basically a speaker or a foam plug with a speaker surround. However, it has no voice coil, and takes its energy from an nearby componet, usually a regular woofer. In your case, the nearby componet is your kick drum. DW uses this concept in it's "woofer" kick drum add on.
The end result of this process is deeper bass, giving you more "in your chest" bottom end. That's what your engineer was up to.

The question I got is about the signal that comes out of the amp...do you have to alter the signal through EQ or something...?? What do you do to it when it comes into the desk...??
You treat it like any other drum mic. You tweak it, EQ it, etc. It sounds very low and a little muddy - you definitely need to also use the close mic to give the drum more attack. But it fattens up the sound bigtime when you blend it with the channel the main kick mic is in.

Mr. A, This is more a mixing question: Did the engineer record a separate track for the 'radiator' or did he just use 2 mics and print it to 1 track?

Separate tracks. That way we can tailor the sound to suit the songs as they evolve on tape. (Actually, as they evolve in Pro Tools. We tracked to 2" tape, to get that "analog warmth," and then moved all the tracks to Pro Tools.)

That's what I thought but I'm just keeping my ears open to hear different ways of doing stuff. My buddy does the same thing with 2" only he uses a combo of Digital Performer (doesn't use the audio though), an Akai Hard disc recorder and a 2" deck. Kinda strange that he does the Akai thing when he's got Digital Performer but... Gets a good sound from a set of late '60s Ludwigs too. Thanks for your input!

Aside from the amp acting as a mic, it seems that you would have to:
A: Have a center hole cut into the head OR B: Use no Head
This way the air/sound vibrations will travel to the AMP/Mic with more definition to vibrate the diaphram on the amp/mic. If you had a off center 5" hole in your head or no hole at all, then I would think that is will affect the sound that you want to get out of the amp/mic.
yes?

From what I learned reading the thread, I would agree. I'm planning on trying it with no front head.

this is a great trick to know about but I usually have so much low end in my kick using a regular mic I have to cut out some of the low end freq's with eq. I don't believe the amp as a mic trick is used all the time, although I could be wrong havn't tracked in any million dollar studios lately I personally havn't tried it, and yes I have a resident bass amp in my studio...but it kinda seems like a hassle to me.

Sorry to come on board WAY late. It's a simple trick. You simply solder wires to the speaker cone connection terminal. The wires you solder are in the same configuration/format as a microphone cable. Hence you are creating a microphone with the speaker cone. The only other thing you need to do is suspend the cone somehow. In Mr A's case they just left it in the speaker cabinet. A lot of engineers use a woofer from the industry standard Yamaha NS10 monitor. BTW, if you can't be bothered to do all that or are electronically challenged like me  Yamaha market a ready made version of Mr A's mic. It's called the [urlhttp://community.drummercafe.com/index.php?action=loadpage&subdir=reviews&content=yamaha_skrm100.htm] Sub Kick[/url].
