Adding a CTS Horn and L-Pad

Sign in to disble this ad
So I own a Crate BT-220 combo amp, and it sounds pretty good. I replaced the speaker to an Eminence Basslite 15, and it sounded even better. I was thinking that adding a CTS KSN1165A piezo bullet tweeter might give me a bit more treble. So there is a comment on this site about adding an L-pad.

CTS / Motorola KSN-1165 Surface Mount Piezo Electric High Power Bullet Tweeter</font>

It says: "Crossover Required: None. The Piezo Element Requires No Additional Crossover. However, a 20 ohm, 30 watt square ohm resistor should be used In SERIES when adding an L-Pad control."

Could anyone of you guys draw a picture of how exactly to do this?

Plus, I really don't know what a "20 ohm, 30 watt square ohm resistor" is or where to get one...I also don't know what L-Pad to get...

Could I theoretically just wire this horn straight to the 15", + to + and - to -, just run lines off of the speaker?

Any help would be great! Thanks again for any advice..

The price on that is ten times what it should be. You can't use an LPad with it. It should have a real crossover, not just a resistor. If you use just one it will probably blow. And you should never use a 15 and tweeter, always a 15 and a midrange.
In short, don't bother.

Thanks for the post! Any other opinions or ideas?
