Really large! But amazing sound quality.
I guess I didn't read the description well enough, because I was expecting a speaker much smaller than the one I got. That said, I am not at all disappointed. In fact, since I got it for a Halloween display, now I can paint text on it and it will double as a gravestone decoration. The sound quality is phenomenal. I won't claim to be an audiophile, but I can identify tinny or too bass-heavy speakers when I hear them. This is neither. I have it hooked up to a cheap Pyle 200W amp with a bluetooth connection, and just playing music from Pandora on my phone sounds amazing. It's kind of sad that this speaker that looks like a rock produces better sound quality than my home entertainment system. I would purchase this again. In fact, I probably will purchase more of these soon.

Terrible speakers
I bought two of these speakers, one in 2020 and the other in 2022. Sound quality was ok at the start. they now both sound awful after 3 and 5 years. My other rock speakers and Bose speakers I have had for 25 years without issue. Save your money on these.

It works fine, but we were surprised by the size
This is listed as 8 inch rock. Itโs about 18โ high. It works fine, but we were surprised by the size. Itโs pretty big

Tons of sound
I have two speakers for back yard patio run off a Sonos Amp (newer model). Sound quality is good and they are LOUD. Sound covers my entire 2 acre back yard and more when turned up. Easy to install. Only downside was the โstoneโ finish they come in from the factory. Itโs terrible, doesnโt look anything like natural stone. I found a brown camouflage spray paint from the store and painted them myself. Now people have a tough time finding them in the landscaping. Probably voids the warranty but the original paint job did not look natural. They are quite large as people previously mentioned in their reviews, but itโs an 8โ sub so the frame has to be fairly big.

Better than expected
These speakers sound great. They have plenty of bass without a sub. Easy to setup and use. OSD customer service is awesome. They walked me through options for speakers and helped me pick the right ones for my yard.

Obvious differences
Product you receive is different than whats shown in the pictures. OSD support gave me the run-around and conflicting incorrect evasive answers, everyone I spoke to seemed very irritated. I never connected or tried the speaker because after unboxing it I noticed that it didn't appeared the same as the picture on Amazon. The picture on Amazon shows a small 1" grill drain hole below the large grill opening for the woofer. , I also noticed the hole opening for the wire to enter the bottom of the speaker was huge and Silicon application is messy, hole is like 2.5 to 3 inches diameter covered in Silicon. The speaker isn't the same as in the picture and MAY be a previous revision but I am not comfortable or happy paying full price for obsolete product or a product with so many obvious differences. OSD is in California, this product shipped from KS, MO.
