Guaranteed to sound better than most rock speakers on the market or your money back! The RS680 rock produces inconspicuous sound for medium sized backyards, pools, patios and gardens. Built for quality and performance, these all-weather rock speakers are safe from salt, water, pool chemicals and more.



Our HF series rock speakers provide high fidelity sound from an enclosure that blends discreetly with natural outdoor surroundings. Designed to emulate natural rocks, they are cast from glass-reinforced resin to create sturdy enclosures with low acoustic resonance for better sound.


With our new revolutionary process, the speaker remains completely hidden behind a fully painted aluminum grille that matches the rock speaker surface and texture. The speaker is nearly impossible to see and will not rust or oxidize over time.


The two-way, co-axial woofers are made from a special weatherproof nylon frame that stops the magnet from rusting. Rubber spiders, in the polypropylene woofer, seal the tweeter posts and keep water and moisture from entering the voice coil. Even the wires inside the speaker are coated with silicone rubber so they won’t corrode.

  • Rigid, Acoustically Inert Enclosure, Aerospace Grade Multi-layer Composite Cabinetry

RS680 Ultra Sound 6.5" Rock Speakers Pair  (HF12)
Question: I'm looking at making a purchase of your outdoor rock speakers, and not sure of which size/model will work adequately enough in the space I have. The outdoor yard area is flat & open (no walls, rocks, structures etc. to block) of just concrete patio, grass & inground pool. I'm thinking I should get 4 speakers for placement in each corner, as the area of coverage I'm desiring is about 48 feet wide by 65 feet long (over 3,000 sq ft). Do you think 2 pairs of the RS680 (HF12) be enough? I'm trying to keep speakers as small/affordable as possible (to blend the best & also less space for winter storage) but want to have good sound. I do not need/want to "blow away the neighbrohood" (actually I don't want to force my music on my neighbors) but really want decent sound for just this area only. Also, this model says 175 watts...is this the total for the pair? Would a receiver such as the Sherwood RX-5502 4 channel listed also on your site be an adequate pairing for running these 2 sets of speakers?
Answer:
RS680 is a very decent 6.5" rock speakers, very close to the top end RS690 rock speakers but in a river rock shape. Running two pair of them in your size back yard and doing the task you required is plenty enough for the sound coverage and performance.
The 175W is for EACH spaker which is peak, you will never play that loud only in music peak maybe you can reach that level. So a RX5502 or better get the MI5 amp to power two pairs of them.

I had my electrician install four of these speakers (in grey) yesterday. They were installed around a 20 by 44 foot rectangular pool in a rather large backyard. We hooked them up to a Pioneer 818 receiver. I'm no audiophile, but the system sounds great! For the price, these are great - no need to spend more money! - Brian

These are great speakers; I love the sound quality and design. - Will I Am a music lover

Your speakers ROCK!!! No pun intented. I wish I would of found you a little sooner so I wouldn't of had to pay for the overnight service, but it was well worth the money. The HF12s arrived in time for the party and the sound is great. Thanks, Sam - Sam

Im somewhat new to online shopping. This was an excellent experience. It was fast, easy and they delivered what they promised. Absolutely customer friendly. I received very good value. - Jim

I am very impressed! These speakers sound awesome and fill our good sized AZ backyard with great sound! - Brittany

I purchased a set of these speakers last year and had two full seasons to rate them. First I had a 100w per channel receiver pushing them and they sound very good. I upgraded to a 150w per channel receiver and they sound even better! Don't skip on the power I hooked up a 100w sub and it knocked my socks off. What a great sound I have on my patio and backyard. When we have parties on the patio my guests are impressed with the sound quality. Believe the reviews, these speakers are impressive. We had a very cold and snowy winter last year and there were no problems once spring came. The speakers "Rocked"! - Joe

Reviews influenced my decision to purchase these speakers. Very impressed with speakers. Great customer service. The clarity and base is super. Would definitely recommend anyone to purchase these. These speakers ROCK! - Wayne

These speakers are great. They have clear sound and can actually reproduce bass pretty well outdoors! My neighbors have noticed how good they sound. Nice speakers! - Paul

just hook up my rs680 rock speakers around the tiki bar the sound is amazing and for the price you just can't beat it - bob

Got these for Father's Day. Installed at a cottage lakeside - about 25 feet apart. They sound amazing - better than home speakers. I cannot believe that these are only $100 per pair. They are very efficient as well - and produce very clean sound at a distance. You can buy 12 gauge landscaping burial cable at Lowes - which is great speaker wire. I'll be back to OSD - VERY IMPRESSED !! - Todd

very impressed..sounds terrific in my backyard on each side of the pool. the quality far surpasses the great price. - corey

THESE WERE PERFECT FOR MY YARD.NOW MY POOL ROCKS ALOND WITH THE HF25 STUMP SUB MY NEIGHBORS REALY DISLIKE ME (AW TOO BAD) - Jamey

I rarely buy anything on line but this purchase may change my mind. The speakers came as promised. They were in perfect condition and they sound very good. I would recommend buying from them again. - Pat

I just got mine in the mail and plugged them into my indoor stereo (it's raining outside, so I have to wait to install them permanently) and the quality is AMAZING. I have indoor speakers that cost three to five times more than these that don't match them in quality. I would have bought the HF14s but they were too big for my flower beds. I can only dream of how great those sound! - Kevin Rock

Pleased with the quality of the outdoor speakers and for the order confirmation emails and notifications for back ordered items (speaker cable). Got great sound from my ipod out by the pool! - Danny

Price is excellent! Customer service is exceptional. I sent several emails with various questions, and I always received a response within 30 minutes. Amazing! Product is as good as they say it is. After delivery of my speakers, I went back on line and ordered two further products. TA. - Todd

No doubt about it. These really do rock! The best product for the money hands down. - Nick

Who would have thought that after two years and a blown woofer, I would have received the response and customer support from OSD? Well, thanks to Dave and Linda, they not only addressed my needs but repaired my speaker by installing a new woofer, thanks. The speakers sound great, produce clear sound and can handle 100+ watts without distorting. Thank you! - John

Wow is all I can say...I never knew what stereo sound was like in the backyard. No longer do I have to try to tune on a little portable radio when I work in the backyard....you guys are amazing....highly recommended!!!! Huntington Beach CA - Chris

Just got the RS680 HF-12's. They are way beyond my expectations! Hooked them up and I love them. I am shocked by the clarity and the tight sounding highs and lows. Sitting outside having a beer has never been better. I am very satisfied. - Eric

Speakers were exactly as described. They work well and arrived when I was told they would. - Cutis

Great prices, easy to use website, fast delivery (company is local to me). Outdoor speaker depot met just about every expectation, and exceeded in price to quality ratio. The rock speakers I bought (HF12) were relatively inexpensive ($119 for 2) but the sound quality is exceptional for the price. I am planning to redo a couple of rooms in the house and add in-wall surround speakers for the sound, and I will definitely come back and shop with Outdoor speaker depot! - Howard

gentlemen; received speakers Friday. hooked up this morning and sound great!!! my home is in a rural setting and with the open spaces i don't lose any clarity. would recommend you and your products to anyone. keep up the good work - Paul

Very satisfied with my purchase all around! The standard shipping was excellent! I live nearby in Los Angeles County and I couldnt have gotten my items any faster if I had driven down and picked them up myself! The selection, prices and quality of items couldnt be any better! I am very happy!!! - Eric S.

I bought a pair of speakers from outdoor speaker depot. They was $119 for both didnt remember an option on shipping I want even sure what it was untill I paid then it appeard. But seem very fair, Not some blown up cost. around $30 for both. they arrived within two weeks and was box twice. I mean awesom protection there. I hooked them up expecting ok sound for two speakers I paid $150 and i was amazed. they have 175 watts each and sound perfect to me. I hooked them up to an amp and that is connected to the computer where all my music was loaded into mp3s about 6500 songs and again was worried about cranking it up afraid the sound would go to poop. But did go up to 75% now I have some old neighbors. and it was great. sounded like a concert. clear. I have an 30 ft by 20 ft patio and I can hear it fine every where. the rain no problem. Thanks for such a great product. - Joseph

These speakers set up in a matter of minutes. I love plugging in my ipod and listening to music all throughout my yard while I am working in the backyard. Most of my guests don't know where the noise is coming from, but they like it! - Jeff

These are great. Would def buy again. Long Island, NY - Greg

I purchased two pairs of your HF12 (RS620) Ultra 175w for my backyard after a lot of research. Let me tell you they are great! I had my wife's 40th birthday party in the yard and people could not stop talking about the rock speakers! I hooked it up to a Pioneer car radio with a marine cover that is over by my barbeque island. I ran 16g low voltage light wiring through my slope for speaker wire (buried). I can tell for the price and the quality of these speakers, there is no competition! Two of my friends have already ordered now. Thank you and your staff! Redlands, CA - Tony

I've had these speakers about a month and I am very pleased with them. They sound great. I really didn't expect sound this good. Connected with 100 feet of 14 gauge 4 conductor direct burial cable and the AquaBlue wire nuts. They were extremely easy to set up.(except for digging the trench) I had my annual Tiki party and these speakers blew everyone away. They do not disappoint. The 5 year warranty is a big plus. - Smitty

Excellent service. I purchased a pair of AW650 patio speakers first. They have an awsome sound. a couple of weeka later I purchased a pair of HF12 rock speakers. The sound and quality of both types of speakers is unbelievable, especially for the price. The delivery speed was excellent. I placed my orders on Monday and the speakers arrived the following day. I will be purchasing a sub woofer in the future. Steve - Steve

I purchased these speakers over two years ago and they are still going strong. Hidden in my landscaping these speakers work greate for lazy days working in the yard or cranked up for my annual labor day party. No problems handling the Western PA weather either. - Jeff

Installed 4 HF12 rock speakers around the pool last night. WOW!!!!!!! The distance between the 2 pair of speakers is 60 feet in length, 35 feet in width. They fill the entire area with tremendous, clear sound. The bass response is better than expected, crystal clear highs and mids. I almost spent a fortune on rockoustics after hearing them at a freinds pool, basically the same size area as mine. I would put these HF12's up against them any day, and at 1/4 the cost, need I say more. Thank you for great product at a great price. Can't wait to crank it up this weekend! - Bill

Send me a catalogue of Ultrasound speakers bskaputa@coppernet.zm - B S Kaputa

Received my speakers yesterday. I was very pleased with the quality and bass response of these two speakers. For the price they cannot be beat! thank you rick - Rick

excellent sound- so clear. using them as anti noisy neighbor speakers. they got the message loud and clear - erik

Just as everyone says these speakers will amaze you everytime and for any type of music ,Its amazing no matter how far you separate them they still image quite well and pump out some nice bass Just be sure you hook them in sequence correctly or the bass response will be flat when you stand between them. - Michale
