tweeters horn vs dome

I disagree. The great advantage from horns in vehicles is

1) allowing for more equal pathlengths among the most point source obvious frequencies (high freqs)

2) The primary advantage from horn loading is they are able to amplify the lower range of what the driver can reproduce. This makes achieving a good frontstage easier.

The cons of horns are

1) you will need a good 1/3 octave EQ to get very good results from horns

2) All horns leave a signature, no matter how slight .

I have owned USD 7.0s with full Rane processing, and MB Quart with only a stereo 1/2 octave EQ, and I will never go back to horns. Contrary to what is said about their installation, you need to be a master installer and physicist to achieve a good install and resemble factory equipment with HLCDs. Basically if you need to ask about them, avoid them, or be prepared to drop some cash with a proven, experienced installer(s).

Good luck on your quest.

Ok thanks for the input guys when i said home audio i mean to say like the big dj box speakers not really home audio and other than the cheap speaker/box kits at places like walmart i havent seen the horns installed in many cars so i was just wondering after someone told me they have a greater efficientcy. Thanks for the input i think ill stick with the dome tweeters hehe :)
