Features & Specifications

How Long Can this Speaker Last Outside?
OSD outdoor speakers are developed with harsh conditions of the outdoors in mind. Our rock speakers use only non-water-absorbing materials and won't absorb any water. This is critical in winter so it won't freeze and crack. The shape is designed to withstand large amounts of pressure, extreme temperatures and moisture. This omni speaker will last years but it's important to take care of them. Storing them away from extreme weather conditions will only lengthen the time you will enjoy outdoor speakers.


Other Product Info

Audiophile sound. Guaranteed to sound better than most rock speakers in the market or your money back. The omni rock provides clear, dynamic sound with great volume potential for large open areas.

Are these speakers available with a 70 volt transformer?
1 Answer
Hi Marty, You can run them with a 70v transformer, but they do not come with the option built-in. We used to carry an outdoor rated 70v transformer, see below: But we discontinued it. I believe we're supposed to be getting a new version in, but in the meantime, you can find a similar product by searching "Outdoor 70v Transformer" on google. BM 2663

In your product pictures it shows the RS660OM wired as satellite speakers from a Sub. Do they provide a full range sound and is there a built in crossover and if so what are the cut off frequencies?
1 Answer
Hi John, The RS660OM have a very good range of sound. The frequency response for these speakers are 48Hz - 20kHz. There is not a built in crossover. There is a 6.5" Polypropylene woofer and a 1" Polyamide Dome Tweeter. CS 2456

How many conductors are required for each individual speaker?
1 Answer
Hi Scott, This features a single (+/-) input. You would need to purchase two each for a stereo pair. An alternative would be to use it as a single mono speaker if you have the capability of bridging your amplifier. We do offer Dual Voice Coil speakers (Rocks, Patio and In-Ceiling versions) designated by TT in the model name. TL/MA

2 years old and still great!
I bought a pair of these two years ago and they are still performing wonderfully. They have been frozen in winter, and baked at temperatures of well over 100° in summer and sprayed by the lawn sprinklers and in rainstorms. They are really tough, still look great and sound better.
Prostough and good looking
Conshaven't really found one yet

Good Outdoor Speaker
Replaced the same unit from 4 years ago. Pond had overflowed and it was underwater for a few days. Dried it out and it still worked, but volume could no longer reach full level. New one works fine, and we have raised level to assure it does not flood. Rain is no problem, only flooding is.
ProsEasy to Mount, Easy To Set Up, Good Power Output, Attractive Design

These speakers beautifully add to our Xerrascaped BY. HOWEVER..... One problem was the representation of the product online. Pictured in the description were two speakers and I thought that they came in pairs. Should have been clearer that the customer needs to order two in order to get one pair. Also I ordered"RS660-OM" and received "RS820-OM" The packing list said "RS660-OM" but that's not what I got. Upon realizing that I should have ordered two, I immediately placed another order. This time I got what I ordered ("RS660-OM"). Now I have a mismatched pair of speakers, but I'm not really that upset nor that critical about outdoor speakers being matched. I just kept this odd couple because I didn't want to go through the hassle of returning products and waiting for replacements to arrive. All in all, they are really attractive speakers...but the RS820-OM really outperforms the RS660-OM.
ProsEasy To Set Up, Good Power Output, Appear to be well built, Great Sound Quality, Attractive Design, Sound is quite good

Quick shipping, delivered as promised, and pretty darn good sound, not too shabby if you ask me. I used these to replace a 7 year old set of Rockustic speakers, and for the money, you can't beat them. They fill my patio with music, and really get after it when I crank them up. Buy them if you want real good speakers at a great price.
