Queries on Celestion horn tweeter response

摘要

I have been looking at the specs of the Celestion compression driver used in the Senator and Majestic speakers. Whilst the curves are excellent at high power levels, the lower levels don't look so good. The compression driver is quite efficient and according to Celestion, intended for larger auditoriums where it can be driven at optimum power levels. Lounge rooms of the average family home being much smaller only need a fraction of these compression driver's capability to achieve a balanced SPL and therefore they would appear to be working in the poorest part of their performance envelope.
