Just got this setup, I kind of like it better than my Corsair SP 2500... Just need to add in a subwoofer.. Since there isn't a "SUB OUT" on the amp, how do I go about adding one in?
Was an old time audiophile.
A crossover set up can split frequencies from speaker output. This is frequently included in powered add on speaker(s).
There are amps that split subwoofer signals and subwoofer only amps.
Generally you need to know how well existing speakers handle bass to choose seamless bass response.
Inexpensive crossovers tend to "fade out" / fade in at crossover point. Some are more direct. Which is better gets extensive debate.
