Interested in DIY? There are many, many options. Have a look at my horns for a sense of what can be done with some elbow grease, but you would be wise to set a budget. For example, my tweeters cost as much you have in your horns.
Good Horn Speakers Of Moderate Size
I currently have the Hornshoppe's Horn, a pair of subs, and a super tweeter. I like this system, but wanted to get a sense for what is available if I spend more. Examples of other speakers I have considered: Klipsch Heresy III or Palladium 17 and Avantgarde Solo. The larger Klipsch and Avantgarde models are just too big. Any other suggestions would be much appreciated.
