Hi All, You're probably sick to death on this subject! I've just fitted a set of dixie horns to my '67 MGBGT (Okay, not quite a Charger!). They're made by Alpex, and I'm not really too sure how good they are. Trouble is, they seem to play very quickly and they're very high pitched. Any ideas how I can slow the tune down a little, and get them sounding a little more in tune - they currently sound a lot like this: 
 But these are Alpex horns, and these sound okay... 
 Hope y'all can help!
