Axiom Audio M3 Bookshelf Speakers

Woofer size is only 1 element of the bass extension; cabinet size and number of drivers matters just as much. In this case, the M3 only has 1 woofer, therefore the total power for this woofer is shared between the mid-range and the bass. Given only 1 woofer and the cabinet size, I'd say 65Hz is pretty good. Also, keep in mind that 65Hz is the linear frequency response up to -3dB. It will output lower frequencies than that, but you loose power (ie volume level) as you go lower. Axiom has frequency graphs for all their models on their website. Here's the one for the M3: https://www.axiomaudio.com/pub/media/catalog/product/m/3/m3_freq.gif Going back to the number of drivers and cabinet size, if you look at their M5 that has the same tweeter, same bass woofer, but now adds 1 dedicated mid-range woofer and a larger cabinet, it goes now down to 45Hz. Tower speakers with bigger cabinets and more drivers go lower. I'd say those are suited for casual listening of music that is not too bass heavy. For music with deeper bass, you'd want to either get towers or pair those with a sub. For movies, you'll definitely want a sub.

How come only down to 65 Hz with a 6.5 inch cone? Perhaps conservative? Perhaps explicitly designed for sub integration? Just curious. They look great.
