PP-SALB-EVM: PP-SALB-EVM ISSUE

Hello Customer,

Can you share your basic specification of your speaker system? Like the maximum output power for both your tweeter and woofer?

Which amplifier is used? TAS5766 or TAS5825?

Can you share impedance of tweeter from the datasheet?

Regards,

Alix Wan.

Hi Alix Wan

This system will be based on a single COAX driver. So a woofer with a tweeter in the middle.
I have attached the datasheet for the driver. I am using TAS5825 amplifier.

I suspect that the impedance measure expects a different curve, that what it gets. I can try to prepare some screenshots of the measured results. Any recommendations on the frequency range to use for the IV measurement of a tweeter?

As you can read in the datasheet, the maximum power output are about 50W total.

Hello customer,

Do you expect a 1.1 system (1 woofer + 1 tweeter)?

Sorry but i cannot find the datasheet enclosed by you. But for TAS5825M, it cannot deliver 2 * 50W application, but it can support 1*50W in PBTL mode.

Further, as to smart amp algorithm, it is usually used for smaller speaker to achieve louder sound. For large output power, it is not necessary.

Last but not least, for modeling of tweeter, fs is usually larger than 1KHz, hence you can configure as below and fit again:

Hi Alix,

For a tweeter with a Fs of 1300Hz. What range should be used?
