Recently my home and car divisions had the opportunity to work together on an interesting project. We needed to produce a “nightclub” like sound on an outdoor deck. Obviously, this meant that we needed plenty of bass! and the highs had to be loud and clear.
Producing the highs was easy. Our home division, Cutting Edge Home Entertainment, offers some of the best products available. We used 4 of the Klipsch AW650 All Weather outdoor speakers and a SpeakerCraft BB2125 amplifier. By spacing these speakers throughout the listening area, we created excellent results that were very loud yet crystal clear through the entire deck and backyard.
Then we had to tackle the Bass… That is where Mobile Edge came in! We decided that Memphis Marine grade subwoofers were the way to go. We used 4 Memphis 12″ dual voice coil marine grade subs and built very custom enclosures. We couldn’t mount the subs on the deck or the home so we decided that the best solutions was in between the floor joists, UNDER the deck!
We wanted a very low response from the subs since the Klipsch outdoor speakers would be handling everything but the lowest of lows. We ended up building 4 ported enclosures that were tuned to 37 hertz. We made each of the boxes 14.25″ wide so that they fit easily between the floor joists.
Because the boxes would be out in the elements, we built the boxes out of marine grade plywood and put 6 coats of polyurethane on the exterior (2 on the interior). We used roofing shingles on two of the sides to further ensure that we would not have any issues with water.
In order to keep small animals out of the box, we used wire mesh over each of the ports. The end result was a unique enclosure that was extremely functional.
We mounted boxes on a slight angle with the subs facing down and toward th foundation. This way, we could take advantage of corner loading for an added bump in the bass response. It also allowed for the water to roll right off of the boxes.
We used 2 Klipsch RSA500 subwoofer amplifiers. Each of these 500 watt beasts sends 250 watts to each subwoofer.
Let me tell you…. turning this on made me feel like I was 18 years old again and lighting up my first sub in my 1985 Grand Am! It sounded amazing! The bass hit hard and tight and the highs screamed. We crossed over the subs at 60 hertz and let the Klipsch All Weather speakers handle everything else. All I can say is WOW!
Now we just need a disco ball!
