Pyle PLMRW10 10" 500 Watt 4 Ohm Marine Subwoofer White
Enclosure/amp for patio use?
I am considering purchasing two of these to fill in the low end from my patio speakers (two up on the deck, and two down in the patio area below the deck). I have a space under the deck to (semi) hide the enclosure, so it can really be as big or small as I want. I am thinking two in a single box (divided so they each have their own enclosed space). What size sealed enclosure is recommended, or should outdoor subs always be ported? Advice on port size and length would be appreciated.Would the Dayton SA70 be enough to drive both if I connect them in series for 8 ohms? I don't need to rattle the ground, but I would like to be able to notice an improvement. The run from the amp to the subs will be about 25 feet if that makes a difference.
I have not personally installed out door subs, however I have know of someone who did. With that being said, I can tell you that it is a monster job trying to pinpoint bass outdoors. Bass waves are big fat waves and usually if there is no way to trap the waves they will tend to carry the bass into the oblivion. A good example of this is often noted in home theater set-ups. Most people probably don't stop to walk around their house to hear what is going on. However, in most cases if you perform this little experiment you will notice that the bass will be overwhelmingly louder at the point opposite the sub. So, what does this mean? and how does it apply to your situation? Okay, in my personal experience I have heard an outdoor set-up that utilized two 10" subs being pushed with about 200 wpc and it really sounded trivial. The huge space outdoors is allot like having a really big living room, for practical purposes lets just say 40 X 40 , which is really big. It will take much more amp power to fill that room compared to one half it's size. So, long story short I don't think a 70 wpc plate amp is going to power a pair of 500 watt subs. Moreover, If I were doing this job I would build two sealed cabinets, one facing opposite the other, this will allow the frequencies to move around a little. On the good side, this will allow you to retain more of the bass wave, on the downside you will lose a little on the low end, but it should not matter that much. I would not power them with anything less than 500 watts per channel @ 4ohms. When you are outside all of the laws of physics apply, Hope this helps.
