Those Peavey's mimics the Electrovoice SM 120A in terms of design concept. No matter what you do, they will not deliver anything significant above 10 kHz. It is very evident that you are lacking high frequencies when using such a horn solely for high frequencies. They shine best from 500 Hz - 2 kHz. The Peavey offers a wide dispersion (around 100 degrees and higher) like the Electrovoice. However, it comes at a cost of lack high frequencies. It is a combination of a Hyperbolic and Radial if I remember correctly. Best Regards, |

ok then, now since that's established, I would like to address my previous post please which was:
So maybe best I simply add a good tweeter to the existing internal horn? If yes, I don't want to go with a 3way setup so how would this work, connect the tweeter to the horn wire on the internal crossover?

Those Peavey horns are radial not constant directivity, and as such will beam progressively as frequency rises.

Why does the dispersion come at the cost of high frequencies? I don't see an engineering reason as to why. It may be that the drivers which are typically mated to the horns can't reproduce them, especially in their original as-sold configuration. But given the right driver I don't see why the horn couldn't. Discussion of directivity with frequency is also another matter. If anything the logical reason for lack of highs (ignoring directivity) is that the horn looks engineered to reach a certain low frequency cut off, and drivers useful down there (especially more vintage ones) would presumably struggle higher as a trade off. |

So I've narrowed down to 5 tweeters guys, can I trouble you guys to tell me in which order 1-5 which tweeter I should try to get please? This is for my home system in a one car garage.

From those 5 it would be CP22.
Otherwise I would use CP21/F Either which, a crossover @ 8500 Hz with a 18dB/oct slope is the ticket for them. |

Just do this, and run it active.

Just clear one thing up for me please anyone.
I am not understanding why switching from a 22"x12" horn to a bigger 33" wide horn would not give more highs than the smaller version? Why in this case doesn't size matter or what's the purpose then of manufacturers building larger sized horns, it is because the larger the horn the more coverage you get but not more frequencies? Even with tweeters a friend of mine has these larger than normal tweeters so why make the larger sized tweeters?
