Author Topic: Very high frequency reproducer Jonathan Bodge Film Handler Posts: 83 From: East Dorset, VT Registered: Nov 2006 posted 04-09-2010 08:59 PM                     Do any of you know what Amp/speaker or transducer that I can put together to amplify 30k hz?  |  IP: Logged Ian Parfrey Phenomenal Film Handler Posts: 1049 From: Imbil Australia 26 deg 27' 42.66" S 152 deg 42' 23.40" E Registered: Feb 2009 posted 04-09-2010 09:25 PM                     We need a bit more info to give you what you need so if you can throw up any additional requirements that would help. Here are a few items that MAY be what you're after. The Motorola KSN-1016a goes from 3.3kHz to 40kHz and is a panel mount rectangular integral horn-driver. The Motorola KSN 1188 threaded driver has a response 0.8kHz-30 kHz and screws into standard threaded horn throats. Advantages with piezo drivers?...They (usually) require no crossover bar a limiting resistor and have high power handling. They are usually cheap as, too. Negatives...usually sound naff and can be harsh at high power. Google these and see if they are what you're after.

But this begs the question: Why? Are you trying to piss off every dog in the neighborhood?  |  IP: Logged Kenneth Wuepper Phenomenal Film Handler Posts: 1026 From: Saginaw, MI, USA Registered: Feb 2002 posted 04-10-2010 07:37 AM                     High frequency audio is a great roach and rodent repellent!  |  IP: Logged Jonathan Bodge Film Handler Posts: 83 From: East Dorset, VT Registered: Nov 2006 posted 04-13-2010 02:02 PM                     I'm sick of putting peanut butter in traps...  |  IP: Logged
