I prefer the quarter wave tubes over the helmholtz (the water bottle type) where the pitch is tuned by the vibration in the neck of the vessel.</p><p>You mentioned that it has been proven that wider diameter resonators bring out the fundamental more than narrower diameter - can you point me to the research you used to support this?</p><p>Thanks !</p>rebeccakiteMon, 07 Sep 2009 13:24:44 -0000
