I think, I found out… Natural speaker uses LF Flat voicing and as other speaker models has mic simulation. It means: Natural speaker = LF Flat mode (high-frequency compression driver off and flattened frequency response EQ)+ mic simulation LF Solo (“Raw”) is voicing with high-frequency compression driver off but normal EQ. It has NO mic simulation. This way a Powercab works like a typical guitar cab without any filters, effects, mic simulations etc... just a speaker in the box. Does it make sense? For my taste LF Solo ("Raw") sounds amazing!!! It gives real "amp in the room" feel!

That is the difference between "Natural" Speaker and LF Raw??? The descriptions in the Manual are similar/identical, but they sound differently... HF OFF (“Natural” speaker) This is the natural sound and feel of the speaker in the Powercab device with the high-frequency compression driver disabled and no EQ of any kind applied. LF Solo (“Raw”) Uses only the woofer with no EQ applied, allowing it to be utilized like a typical guitar speaker. ???

It depends from the headphones you use... The phones output of the Helix has 12 ohm. According 1/8 rule a headphone should have not less than 96 ohm. Line 6 support recommends to use the headphones between 150-300 ohm. I have Helix LT and I tried a few headphones: Sony MDR-7510 (24 Ohm)...sounded awful AiAiAi T-2 (32 Ohm)...sounded awful Beyerdynamic DT-770 Pro (250 Ohm)...sounded quite good, but it was hard to drive...and uncomfortable to wear for a longer periods and don't liked a curly cable. Sennheiser HD-650 (300 Ohm)... sounded very, very good! Nice warm sound, good sound stage. Highly recommended! I ended up with Sennheiser HD 600 (300 ohm). It sounds amazing! Clear, extremely detailed sound...! Very comfortable to wear, nice design! I would highly recommend it!!!
