newbie sir.. What do you mean limitation sa lower region? Ano ba dapat titingnan para maganda ang lower region?
Limitation iyan ng speakers, not amplifier. 5-1/4” lang kasi ang woofers ng Andrew Jones SP-FS52, kaya limited sa reproduction ng low frequencies (bass), 250 Hz per specs. So if you want more bass, 20–200 Hz, a subwoofer is recommended.
