Poll for Topping PA5 owners only please.

Do you have 8 ohm speakers paired with Fosi ZA3?

Yes. 8 ohm, 98dB sensitivity, compression horns. They pick up a lot.

 

[Guddu]

Yes. 8 ohm, 98dB sensitivity, compression horns. They pick up a lot.

That explains why you feel elevated top end with ZA3.

 

[Talisman]

That explains why you feel elevated top end with ZA3.

This explains nothing, the nominal impedance of a speaker is an arbitrary value assigned, to understand if there is actually an interaction capable of modifying the frequency response you would need to see the impedance curve of the speaker.

I don't have that information, it's a DIY Sound Group speaker they don't sell anymore. Fusion 12 Tempest.

Maybe this will help you,I don't know if it's final but it should be close.you can also sim it if you like following the thread of the link:

Fusion Tempest 12 crossover

Purchased a bare bones Fusion 12 kit from DIYSG back in August 2020. Erich was able to provide me with a list of crossover parts but no photo or schematic of the crossover. My last email response from him was in August when he stated that he would provide some sort of assembly instructions for...

Seems like the upper region is close to 5-6 Ohm all the way up.

Okay… I believe you. Thanks

The PA5 impressed me with the audio quality, but mine went wrong after about 5 months and had to be replaced, so not impressed with the quality control, but it was replaced without fuss (probably because they read ASR) so I was impressed with the customer service. That is 2 out of three.

Well, my PA5 is now producing noise in the left channel. It builds the longer the amp is on. Just changed my vote. Wish they still had the blue color in the newer models.

Another one bites the dust...

Just to clarify - first gen PA5?

 

[Eldus]

Just to clarify - first gen PA5?

Yep, bought it a few months after launch IIRC.

 

[Guddu]

I guess its bound to happen to all first gen PA5, just a matter of time then!
