Review: Looks good. Sounds good too. - Initial review: Looks good, hope it sounds good as well. Awaiting the installation. Pictures are worth a thousand words... 1. Nice big box 2. CES 2021 innovation award. Sweet. 3. Well packaged 4. Comes with adapters, tape and screws 5. Instructions 6. Brackets alongside thicker brackets that I was told to buy by my installer. Apparently, he said the provided ones would be useless for my car (Honda Shuttle). 7. UniPivot tweeter is angled at 15° and can rotate 350° to get that tweeter sound more to your ears. Tried rotating it but it doesn't look like much. Not like the tweeter is directly facing you or anything. 8. Rear of speakers. They are weighty. 9. Front of speaker. 🔊 Note the little button for a louder or quieter tweeter sound. Not sure how harsh the tweeter can be when it's at my legs anyway. Will update on the sound profile after installation. Hope it sounds good! Final review: Sounds good! Needs to be tuned a little, I boosted bass to max. Nice flat & full sound with no harsh treble, yet detailed. Keep the little button depressed or you'll have plenty of treble missing. Running off a Pioneer head unit only. Though one thing; am not sure if they will hold up to rain as my installer told me rain water will enter the door. If they die will just get a different brand. Compared to the stock $2 looking speakers on my Honda, these are great and the ones to get! Update: A downpour last night and the car was left out in the rain. I drove after that (didn't wind down the windows) and the speakers played normally. The next day, they were okay as well. So they seem to be somewhat waterproof. But I'm not taking any chances and installing some silicone rain guards (with a hole in the back) for some protection.
Review: Infinity kappa - Nice crisp sound....awesome speakers...

Nice crisp sound....awesome speakers...

### ⭐⭐⭐⭐⭐ Excelente audio, muy buen manejo de potencia 85W RMS
*by M***L on 29 August 2022*

Me encantó el producto, yo lo utilicé para las puertas traseras de un Jetta MK4, la instalación fue algo compleja por que hice unas bases de montura de MDF, Pero como están instaladas de manera correcta, el sonido es excelente. Para las puertas delanteras utilicé un sistema 60CSX, Y la combinación es una maravilla, suena excelente todo. Lo mejor de todo fue el precio, me costaron $1,099MXN Cada par. Vendí el otro, así que me salieron gratis las mías. Verifiquenlo en KEEPA, es el precio históricamente más bajo.
