Review: 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.

## Questions & Answers

**Q: Does this item come with the adapter bracket?**
A: I'm not sure what adapter bracket is being referred to? There was no mention of any adapter bracket in the product description when I purchased my speakers. The package came with 1 pair of speakers, 1 pair of grills/covers and 1 package of mounting hardware. The speaker frames are drilled with multiple mounting hole patterns. This may take the place of the adapter bracket in question?

**Q: Will these fit as replacement for rockville 6.5 speaker cans**
A: Hi
 The best would be to check with your installer before you purchase the unit.
Thanks

**Q: Will these be OK in a boat?**
A: Well I don’t think they are marine speakers but the cones are stiff plastic, so I would think they would do for at least a couple seasons

**Q: Would like to know the speaker diameter, without the grill?**
A: 6.5 inches.

### ⭐⭐⭐⭐ Great speaker, not much bass.
*by S***N on November 18, 2024*

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.
