I think this is a first?

Post by metrodrum »

So I've been wortking on this problem for a while... The problem, sympathetic snare buzz on a single shell cocktail drum. Full Length Snare on the top , kick drum on the bottom.

Recently - I was working with an engineer, and we applied a bit of the Hemholtz theory of porting a cabinet to a cocktail drum ( albiet bastardized because it's round ) and we pretty much have gotten to a point where you get zero snare buzz out of the top snare
when you hit the kick.

I've had an endorsee gig with one, and recenlt an upcoming article in a drum magazine is going to be doing a review.

I was pretty blown away, when I put a stick on the top head, whacked the kick pedal and with a stick sitting on the snare head, it didn't move, not even a perceptable buzz from the snares.

So, I played it at a gig in NYC, and have to say I missed my toms, how many cocktail players out here use just the minimalist snare/kick/hat setup?

Yah, this was talked about some time ago about porting. It does work, however how much of the tone is lost from kick or snare. Is the snare much dryer, I imagine it is or did you port low on the kick. There is some pics of a ported kit from one of the members somewhere if I remember correctly. Keep up the R&D we love to hear good tricks.

RE: porting

Post by metrodrum »

Hey -

I've isolated both chambers, applied reflective treatments on the snare chamber and
isolated the baffle from the shell itself - the baffle essentially floats inside the shell.

The majority of the porting is on the kick, working the frequency at @ 60

The mags going to post cound files once the review is published.

I also would miss my tom. The cheezy little kit I use now has an external demi-snare, an external tom, and of course the top head of the kick. I have also put together "minimalist" kit, with a full size floor bass and 14" snare, but I always feel as though something is missing in the middle, so to speak.

As always though, the disclaimer is that I actually play in a Pipe and Drum band, and have yet to gig as a solo drummer....the real professionals may have a different idea of what they need to gig with!

Keep the cool stuff coming! I love what you've done with the place! :D

Can this floating baffle tune the length of the drum for a higher/lower snare fundamentals? That would be pretty cool to be able to choose you're own tone. Does the baffle move during transport? Will it change (shift) from gig to gig? I like the sound of this idea? Cool

Moving Baffle

Post by metrodrum »

In theory you could certainly make a moving baffle, with the understanding that it would change the tuning port requirements on both the snare and kick side of the single drum. A variable air vent could solve that, and allow some adjustments by the end user.

Just a thought...
