bass problem in a sailboat


Hi!

I have a sailboat with a nice marine-grade stereo, built by Poly-Planar. There are four speakers, powered by a 4 X 45 (180 watts total) head unit. The speakers each have a 5 1/4" "woofer". I generally like the sound. The not-so-low bass is great, but I'd like to boost the really low frequencies just a little. I listen to mostly classical music, and I miss a few very low notes that I hear clearly on my home system. I'm NOT talking about great volume. I just want to boost the very low bass a little. I did this once years ago in a Camaro by simply adding an equalizer to the factory system. I DON'T want to add an amplifier and subwoofer because I don't need the extra magnetic field nor the additional power drain. An equalizer also seems inappropriate because, in this case, it would be a "set it and forget it" thing that I would hide somewhere. Is there a simple way to boost just the very low notes a little with the existing speakers and head unit?

Remember how power hungry bass is. Even if I were looking for "subtle", I would want enough power for headroom without any distortion. Getting that note at 25hz requires a heck of a lot more power than a note at 15khz, especially if you want clean, tight and fast.
Happy Listening.
Elevick,

I agree. Bass requires power. That's why I'm inclined to believe the RMS output of the PolyPlanar MRD-60 is closer to the 45 watts per channel that the 15 watts that has been suggested. It drove the first dual voice coil subwoofer quite well. I'm hoping this Infinity will be even better.

tscott, don't be fooled by power specs. Poly-Planar advertizes UP TO 45 watts per channel. That's peak power on a clear day, downhill, with a good head wind. Constant power (RMS)is another story. Still, I am constantly amazed at what the average head unit amp is capable of. I am cautiously optimistic.
Baffled,

I'm optimistic too. The speaker hasn't arrived yet, but I've made the preparations. The speaker should be sensitive enough to do enough with a little. Regardless how much power the head unit actually has, it would play the four bookshelf speakers and the dual voice coil subwoofer (without a low-pass filter!) louder than I would ever listen. I'm hoping that this new, 2" larger and probably much more efficient DVC subwoofer (this time WITH a low pass filter) will be even better. Thanks for your help! I'll let you know.
