I have a pair of vintage University "Dean" horn-loaded speakers from the 1960s. PM if interested. There is a massive 15-inch driver in the "doghouse" that makes wonderful bass. Efficiency is off the chart at 104 db at 1 meter at 1 watt, PM if interested.
Horn speakers for vintage sound
I’m currently looking for budget horn speakers in university that are similar to GIP or western electric size is no issue since it will be in the living room my budget is 5 grand if even possible or might even try build GIP speakers
