## Description

desertcart.com: OSD 5.25" Brown Outdoor Rock Speaker 100W Weather Resistant Passive Stereo Pair RX550 : Electronics

Review: Absolutely blown away by sound, build quality and value for money. - I almost spent twice as much as these babies on alternative rock speakers, before settling on the OSDs. Then, I wondered if I’d regret not going for the more expensive ones. I figured I had nothing to lose, as I could send them right back if I wasn’t happy with them. Well, I am more than happy. Right out of the box, I was like, wow... really? I’m powering them with a decent, but relatively inexpensive, Sony amplifier and they sound amazing. (I also went for a good quality, thick, 16 gauge speaker cable - good quality cable makes a really big difference). The separation of instruments and the placement of vocals is very appealing. They’re tight across the range, never getting muffled, with a defined bass, crisp highs and an open mid-range. At this price point, I expected the separation to be a little muddy, bass perhaps a little soggy when pushed, and highs a little bright but that couldn’t be farther from the truth. They’re clean and crisp and a pleasure to listen to. I have them at the back of my pool, facing towards the patio. They’re about 30ft apart and the soundstage is nothing short of amazing at this price point. To float on a floatie in the pool with pool-level music is also quite special. I expected them to be made out of some kind of hard plastic material but they’re made from a rubber-like material and appear to be very well constructed. These speakers have exceeded my expectations and I couldn’t be happier. Buy with confidence.
Review: Amazing Sound Amazing looks - it love the sound and i love the looks of it. i found myself grabbing large chunks of rock from side of road to make it feel more natural. i correctly wired my 4 pairs that’s 8 speakers and it’s literally a concert experience in my backyard. it’s holding up in two hail storms of dime size and hard rain don’t forget dog in yard. this was a sweet buy. awesome investment.

### ⭐⭐⭐⭐⭐ Highly recommended from an audiophile
*by B***P on August 8, 2022*

I have built many pairs of Hi-Fi speakers in the past and invested many thousands in speakers and audio gear so my ears are very critical of quality musical sound and these speakers blew me away. Not only are they a great for the price but they sound so good. I'm driving them with a 100W Fosi Class D Bluetooth amplifier in my backyard and could not be more thrilled with this combo. The sound is rich, bright, crisp and detailed. For this quality of sound reproduction, I would have expected to pay 2, 3 maybe even 4x the price of these speakers. I do have an outdoor subwoofer in line with these speakers so the bass is a bit more robust than if I only had these speakers. The speakers are well built and hopefully will last for many years. Some complained they don't look very "natural" but I think they blend in just fine. For those that are not very tech savvy, these are easy to install, just connect to the speaker wire connected to whatever amplifier you choose to drive them. I think these speakers are a steal. Highly recommended.
