Subwoofer choices
Acoustic, you sound like you’re pretty much up on the sound scene.I like the scheme of that powered subwoofer in your first link, except for the low pass filter. Also, it looks like a surface mount model. I’d think I’d prefer a stand-alone box, to avoid cutting up the boat. I could anchor one behind the engine in the aft berth.I’d like to add a subwoofer with its own amp, like my home system. At home, I have the speaker level output (my receiver doesn’t have a subwoofer output) routed to an M&K subwoofer, through the M&K's high pass filter back to a Polk satellite/sub set of speakers. This takes the bass load off the polk’s.On the boat I have an Alpine 60-watt per channel player with line level outputs. I want to see what’s available to mimic my home system. I guess I have to work with speaker level signals from the head unit on. I don’t think there is any way to feed a line level signal back into the Alpine’s power amp section. Do you think I’m on the right track? I’d like to keep things simple and cost effective of course.I hear what you are saying on primary speaker selection, but I’m limited to the four Bose 151’s that I received from my employer as an employment anniversary gift. Actually, they don’t sound all that bad to me. I’m not trying to duplicate the sound quality of my home system. I’m happy if I can get a decent sound with a lot of clean, high volume. I can’t hear much above 13 kHz anyway, probably from all the high volume Rock and Roll of my earlier years. I have used the Alpine’s relatively sophisticated tone control capability to help out a little, but pumping up the bass without further taxing, or even lessening the load on the Bose speakers is what I’m after. I’m supposing I need to find a 12-volt subwoofer that has the same type of high pass filter the M&K does, and then run the Bose's from that.
