Review: Beautiful, fabulous sound. All over a great product and value for every penny - Absolutely stunned, they are fabulous. I have read loads of good reviews about these speakers and a few negative. All I can say is they are absolutely fabulous. I have them in my semi large garden and they fill it up (2500sqr/ft) . Got them connected with my Denon Cleol and the sound is great, clear and plenty of base. Oh and they are loud even though my Apm is pulling 35w at 8 Ohms, any louder and I would have security at my door. To me they beat Bose hands down. Highly highly Recommended
Review: Mejor que Bose - Quite unos Bosé 251 y puse los Polk. Mejor calidad de sonido. Los recomiendo. Tengo los polk 5 y 4 en un surround sound.

### ⭐⭐⭐⭐⭐ Great sound and easy mounting for a small speaker
*by A***R on 5 September 2026*

Why I ordered this item: My old outdoor speakers finally died on me after a storm last year and I've had a bare wall on my patio since. I wanted something I could mount and forget about, not another pair of plastic boxes that crack after one winter. Likes: * These sound crazy good for how small they are. I've got them mounted above my patio door and music fills the whole area, not just directly underneath. * The mounting brackets are snazzy. You click the speaker into place with one hand and it locks in. I did mine solo without a ladder buddy. * The housing is thick plastic and doesn't feel flimsy at all, even sitting outside in full sun most of the day. * Bass is way better than a speaker this size has any right to have. I wasn't expecting much from a woofer that small. * Hookup was easy, I just twisted my existing speaker wire onto the binding posts and it worked. No likes: * The included mounting hardware is kind of skimpy. I ended up buying my own screws since the ones in the box felt cheap. * Volume matching between the pair was a little screwy out of the box, I had to fiddle with my receiver to get them even. Would I pay full price for this product: Yes Final thoughts: These are good speakers for a patio or small backyard setup, not for blasting music across a huge yard. If your gonna mount speakers outside and want something that sounds way bigger than it looks, these are worth it.
