Review: Happy with my purchase - I am happy with these speakers. They have a decent range from high to low, a clear sound and will get loud enough to annoy the neighbors. They were easy to install and I like they way they look on my back porch.
Review: Updated review March 2021 - Awesome speakers!!! The sound is super clear and they have great bass for the size as well.......they don't have the super deep bass like an active subwoofer. ....but hey, they're smaller speakers. Perfect for the patio or deck! Not too big and bulky but big enough to sound great!! Quality appears great and you can't beat the mounting system!! Super easy to mount in a variety of positions......and the speaker slips into bracket and stays in place so your hands are free to put the cap screws on the ends and hook the wires up!! The engineers actually did a great job with this system! We mounted them under the soffit on the house above the back deck and they're wired into an older Pioneer receiver with an equalizer. It gets -30f here so we will be removing them for winter just to be safe. At under $100 I don't think you will be able to find better bang for the buck anywhere. Highly recommend!! Update*#*#*11/17 Just finished installing two more pair of these in garage. Wow. What a difference these make in the quality of sound......full sound and very clear. Had a full set of samsung speaker that came with surround system out there. Put these in tonight and all I can say is wow!! What a difference! Will be ordering some more to install near our firepit in back yard. ****update March 2021**** These speakers are still going strong!! Have had hundreds of hours of use and they still sound as good as the first day of use. No problems with the weather at all, had to dust them off last fall, (excess dust in neighborhood from road work over the summer). Still would recommend these 100%!!

## Questions & Answers

**Q: We do not have a covered deck. Could these outdoor speakers be totally exposed to the outdoor element?**
A: I have installed these speakers totally exposed and they have lasted several years the grills might become rusty looking depending on the area you're in

**Q: Are these compatible with Alexa/Echo Dot?**
A: These are not Bluetooth speakers so they will not work directly with Echos or Dots and need to be powered by an audio receiver. You can however, use an RCA or Bluetooth connection between an Echo or Dot and the reciever and stream to the speakers.

**Q: Is it two packs of pairs being a total of 4 speakers?**
A: No the 4 is for the size and model, there is only 2 speakers in the box!
These are Great Speakers!!!

**Q: Is it easy to be operated? I hope it will be not too hard to do that...**
A: …Were very easy to set up, and I just connected to the amplifier and then to the record player.…You can buy this amplifier if you are a lack of it.https://www.amazon.com/Bluetooth-Amplifier-Receiver-Integrated-Audio/dp/B07L3F5QQ7

### ⭐⭐⭐⭐⭐ Decent speakers at a reasonable price.
*by S***Y on August 1, 2020*

Product sounds really good. I have a couple Bose speakers in the house, as comparison these speakers are not as bright in sound. They carry a more dominant mid-tone to my ear which is subjective to each person. They have the ability to go pretty loud depending on your receiver and have not distorted. There is a reason they have been in production since 2005. If you are thinking about adding some outdoor speakers but aren’t looking to break the bank, these speakers will not disappoint. I could not be happier with them. My 4 star on the sound is really a preference thing, others may think they are straight up 5. From the install perspective, these speakers come with the mounting bracket, but do not include screws. I used a couple exterior grade screws to fasten to the soffit above my desk. Once the bracket is up, the speakers slide in and then you tighten the cap on either side. Very easy to do (the hard part is running the wires, but that has nothing to do with the speakers themselves). Overall I do rank these as a 5 for value. They are above the quality you might expect for the price point and get the job done. They are a nice set of speakers that should add enjoyment to your outdoor space for years to come.
