But if he's using it as full range speaker without having a sub wondn't require more power. I just did some googling and it this has 15 inch woofer.\n\nSent from my LM-G710 using Tapatalk\n\n\nYou realize generally the larger the speaker it is the more sensitive it is? Hoffman's Iron Law. His are fairly sensitive at 94dB. Running full range does require a bit more power than using a sub to take some of the load off, tho.
