Default 3 way front loaded horn bass bin nob question

Hi Guys
Sorry for the silly question. Aside from having to pad down the mids, tweeter & having lower woofer sensitivity, what is the reasoning behind of not using a woofer with lower FS to attain more bass, assuming the XO is set around 500hz.

Thank you kindly.

Higher efficiency puts less heat through the coil. Also, assuming you are using subs, it isn't necessarily helpful for the mains to run that low.

Hi Allen
Thank you kindly for the reply. Adding Subs will make things more complicated for me.

Complications aside, adding multiple subs is the only way to get really good in-room bass response. So you should consider it!

How low would you run the mains in home audio?

I would simply let the drivers go as low as they reasonably can while optimizing them for the crossover - not the low-end. Then boost up the low-end with multiple subs, all overlapping and Eq'd as a single system. This way it makes no difference how low the mains can go.

My 15" mains only go down to about 60 Hz, but my room response, with subs, is fairly flat down to about 20 Hz.

Thanks, that cleared up a question I've been wondering about. I didn't know if we should cut off the low frequency in the mains.
