View Full Version : driver selection question

04-30-2003, 04:41 PM
In my latest project, I'm using a pair of K25-horns for bass and 2405's for highs.
The problem is to decide where to crossover the bass-horns, and what driver(s) to use for the mids.
If I crossover the basshorns at 400Hz, I could use a high efficiency 5" driver connected to a horn, but If I select a lower crossoverpoint, then the 5"-mids probably needs some help from maybe an 8"-driver to cover the lower parts from maybe180-800Hz.
Please help me out! Any recommendations appreciated!
Suggestions of driverbrands also needed!

At the risk of sounding dumb, what is a K25?

It's a folded basshorn with a 12"-driver to be used in home applications, and with a horn-mouth size tuning the enclosure to 25 Hz. With a good bass driver you get excellent dynamics, low distortion and great Spl / Watt. They need a big room to sound their best though!

Normally you want to cross out of folded horns lower than
400hz because of the midrange coloration that can start to happen from the folds in the horn path.
However I can think of a few folded horn designs that do crossover that high of higher.
