quite fantastic for the price range
Sadly mine was delivered (in the consumer packaging box) in a thin bag… no bubble wrap, just a plastic white bag and of course the big ding right in the center of a grill.Luckily, I’m not needing the grills, and the box itself (while pushed through) encased two styro-foam protetcants for the speakers, and the grills were over the speakers…so, the speakers themselves are fine.Everything else is fine. The box and one grill took all the abuse and they should’ve used at least bubble wrap bag (or a box, as the kenwood box is as thin cardboard as it gets).These do come with everything we need to install.These also are high enough sensitivity to be able to get good volumes from a weak head unit. Using an amp might be pushing them too much, so ensure the amp is set properly.Either way, these are loud enough to be twice as good as the factory car speakers, and for 29 dollars, is incredibly good value.They do have decent mids, and mid-lows but shine in the upper mids to highs. Mine are set to 120hz but were going great at 80hz and at lower volumes could probably handle 50-60hz but I don’t want to overheat them for too long.If you need inexpensive, clear sounding, loud replacement speakers, these will be great.The speakers are entry level and probably the best low budget there is.

Great speaker, not much bass.
These speakers are a good value and sound better than my stock speakers,although the bass is not very impressive. If bass matters to you at all I would recommend passing on these.That being said, they do sound good and are a decent option where low profile speakers are needed.

Excelentes bocinas. Las compre para remplazar las que vienen de fabrica en mi Kia Rio 2020 y definitivamente suenan mucho mejor. Cabe mencionar de que a pesar de que son de 30W RMS, con el poder que envÃa la unidad de fábrica del coche, no suenan igual de fuertes los bajos como con las de fábrica. Sin embargo, ganas mejor nitidez en los agudos y medios.

These speakers deserve 10 stars. These Kenwood speakers are awesome. I have put one pair in my front doors. The clarity, loudness and sound quality of kenwood is too good.For base I have used jbl352 hi in my back doors. They produce good deep base but not great. Also JBL sound clarity is not upto the mark. Just base is good and few treble is good.
