Subkick style mike on a bass cab?

Anyone have any experience with it?

For those of you not in the know, this style of micing involves using a 6-8" subwoofer as a microphone. Reportedly, you can get really great lowend response out of 'em, and as I have a couple of those kind of subs sitting around collecting dust, I thought I'd build one or two up, as its a stupidly easy project (connect XLR cable to + and -, add an attenuator, done.)

Unfortunately, I'm nowhere near my home or my rig until midway through next week, and then its just a pit stop before heading back out on the road, so I won't have the time to build one before February.

So has anyone used one of these mics on a bass cab? If so, how'd you feel about it?
 
I'll sometimes use one, especially in dub, or live drum and bass etc. Anything where the bass dominates the low-low end.

They can sometimes have a use even when low passing in the mix, the can add a smooth shape to the low end of the bass (as in the bass thats let on the track after the high pass) that CAN help if you've got a fairly empty track and that 'area' is going to be noticable.

also I'll keep the low lows in for some hip hop/new rnb or pop tracks, choosing to duck the bass under the kick rather than just carving a space for it with eq's, that can be good.

But really I'll only use one once in a blue moon on bass, and maybe 4 times in a blue moon on kick.

However I REALLY like a crappier speaker (old car speaker or anything really bad) as a crunch mic for drums, they have REAL characters and you can collect a few different ones for next to NO money. You can get just the pole bit of a mic stand (probably a short one) and attach four or more to it, then you have a ready to go crunch box! I'll normally just go through all four and choose one. Crunch mics are an imperfect science, but sometimes one will have a great nasty high mid and one a good sub so then you can use two and have theme relatively phase aligned with no fuss!

Or even a slightly nicer one like a subkick quite far back can get a perspective of the low end of the kit as a whole which you don't get from overheads or close mics. Its is of course a bit tricky to get it perfectly in phase, but with some trial and error and masking tape to mark the floor with positional notes its not too bad! It can really pump up the drums!
 
sometimes a home made subkick will put out a signal that is too hot for most preamps. even with the pre all the way down, the signal could be so strong it clips. some preamps have a -20dB switch.

just in case, just like deluge said, i made a -20db adapter. easy build. didnt actually need it. i suppose the speaker i used isnt as sensitive or something.
 
Can I use a regular DI for this? Sorry if I'm asking stupid questions, but my knowldede of impedance and such is a bit lacking...

Yeah... probably. Wire a jack to the end of the cable coming off your speaker, into the DI (pad in) and out of the XLR output into a mic pre. I think a speaker used in this context is still considered low impedance so the function of the DI is not really necessary, but it allows you to pad it, and balances it as well.

Shouldn't cause any trouble.

If not you can buy attenuators for peanuts or make one yourself for even less.
 
i have a diy subkick, but it stays on my kick drum. the sub kick i have found, competes too much with the kick drum. a nice DI signal blended with a nice mic'd up cab typically fits well in a mix. if you need more oomph, move the mic around or change the mic pre.
