Leslie Horn Driver
Replacing the woofer helped the bass section. The Jensen V-21 driver was replaced with this Atlas PD5VH. It sounds great & screwed right in. (Removing the Jensen took work) Before installing it, I tested it against other drivers using a large re-entrant horn & electronic crossover & my ears. The upper range of the Jensen was around 3Khz, I heard the Atlas at around 5Khz. The two drivers seemed similar in the lower range. They both played well at 300 Hz.
I like this driver & am glad I installed it. I get much more Leslie effect,
probably thanks to the higher frequency range. I haven't yet played out with it, but at home, it is very pretty & musical. The original speakers just sounded like limp hair, can't explain it, just lifeless & unappealing.
The Atlas PD5VH is well made & sounds great in a leslie.
