To expand on what Lonman said, the simple answer is yes, though like he said it all depends on the crossovers. First off, the horns are not going to be getting any extra wattage in this setup because they are crossed over passively in the main speakers already. That is to say that the horns are controlled by a passive crossover in the speaker that is already designating the it receives X through Y frequencies and Z wattage RMS, so that will not change. However, the woofer in your main speaker then receives the rest of the frequencies (within the driver's range) and amp power that is fed to the speaker.

SO, if there is a crossover in your sub and/or in your amp, you can allow the woofers in the mains to receive more power for low/mid-frequencies with the right settings. The speaker is still receiving the same amount of overall amp power, it is just being used more efficiently.

Set the sub/amp crossover point between 90-120 hz. The woofer driver in your 10" mains most likely produces frequencies down to about 80 hz or so. Let's say the sub is crossed at 120, then the mains will only be responcible for frequencies above 120, and will have a good percentage of new available power to reproduce those frequencies. Then again, your sub amp then has to work that much harder as it is now responcible for more frequencies, so it is all give and take.

I personally have my subs in a different sound chain than my mains. I cross the subs at about 105hz and cross my mains through the amp at about 95 hz. This way my mains don't have to go all the way down to 55hz, like they are capable of, but at the same time my sub doesn't have to go all the way up to 120hz.

Anyway, for your settings, play some bass-heavy music and slowly change the cross settings to see what sounds best to you!!

Make sense?
