Bandpass filter required?

[rosenkrux]

Should I include bandpass filters to block beneath & above full range driver limits of 60 hz / 16 khz?

This is for column speakers with 6 full range drivers wired series parallel with each driver rated 3 ohms,50w rms. If filter desirable, beyond online calculators which provide component values,can anyone give me any helpful pointers?

Fullrange drivers usually do not need a lowpass, but a highpass might be useful in order to limit diaphragm excursion. For example, someone speaking into a microphone without a proper wind-blocker will generate low frequencies, which do nothing useful. One can filter them out, for example on the small-signal side, or by choosing a coupling capacitor of fitting value, if the amplifier does not have a symmetrical power supply voltage.

Suggest as a start not use any band pass filters and only use high pass filters if you for technical real world reasons need to limit excursion as guided by grasso789 or if because speaker placement and room integration will give you exaggerated low end, reason is speaker systems is a band pass system in itself and in that its output including room is supposed to be as true to its input as possible then the wider smooth flat response it can cover with less order of roll off at stop bands the closer in theory it would be to input signal. Should you be able to have measurements gear at hand will help a lot to decide if any filters or EQ will benefit your speaker system to perform better than as is.
