I want to use 3 x NP1 for high/mid section of Linkwitz LX521, possible?

https://www.linkwitzlab.com/LX521/LX521_4.htm

I concerned whether NP1s are able to drive the following drive units?

Tweeter (> 7Khz): https://www.madisoundspeakerstore.com/auto-tweeters/seas-prestige-27tffnc/g-h1396-1-textile-dome-tweeter/

Two tweeters are wired in series

Upper Midrange (Between 1K and 7K): http://www.madisound.com/loudspeaker_specifications/H1658-04_MU10RB-SL_Datasheet.pdf

Lower Midrange (Between 120 and 1K): https://linkwitz.store/product/linkwitz-22mg/

Finally, any of AVA high power suitable for 2 ohm loaded for the bass section?

All of the drivers you linked to have easy to drive 4 ohm or higher loads. The NP1 should be more than happy driving any of these directly, which seems will be the case with the fully active Linkwitz LX521.4.

Without additional information regarding the "passive L&C crossover in the LX521 top baffle" of this (older?) version of the speaker that is also mentioned in one of your links, we can't say for sure whether this will also be the case for that system.

For your bass section, we don't currently offer an amplifier that's suitable for delivering sustained high power into 2 ohm loads.

The SET500 is ok driving a 2 ohm load.  Its the highest drive amp built by AVA.

Be aware that when loads get low, currents and heat get high.  At a two ohm load it is quite possible to exceed the amps rated power output without any sound quality degradation (amp will not clip until well past its rated power output).  Ensuring the amp is not blowing fuses and is not getting too hot (a fan could help here if you are pushing things) will ensure a long and healthy amplifier life driving a low impedance load.

Considered use 2 amps on the bass. Then only dealing with 4 ohm for each amp

I have another question for you regarding your NP1 driving another loudspeaker other than Linkwitz.

If a 2 ways loudspeaker that has Dynaudio 24W100, don't you think your NP1 able to drive it? And it is assuming that the speaker has 2 x NP1 biamping the speaker.

I guess the NP1 should be no problem to drive any tweeters.

Thanks again!!

The Dynaudio 24W100 specs you linked to look like a perfectly acceptable load for the NP1.
