SEAS A26 crossover frequency

[nugat]

What is the crossover frequency for Seas A26?
Will be grateful for that info.

Depends. the classic kit doesnt even use a low pass filter.

Hi,

Its simply near 3KHz first order electrical on the tweeter.
Acoustic x/o point is somewhat harder to work out.

rgds, sreten.

Most likely 2kHz, IMO. That's why you need the big tweeter.

Without any bass coil, the -6dB point of the SEAS A26RE4 woofer is certainly about 2kHz. Below.

Peter Comeau used a tidge of slope and a notch in his similar WDA25 EX design, but not much:

Years ago I measured the A25 with a slow sweep, and the acoustical crossover notch
from the out-of-phase drivers was around 2kHz.

From the woofer's frequency response chart it looks like 1500-1600hz is the most it should attempt. The tweeter looks like still good at 1300-1400. So maybe 1500hz is a good meeting point?
