Final Verdict: Which One Should You Choose?

To sum up, it is obvious that there aren’t many differences in the performance of the two subwoofers. They both deliver decent sound quality with nearly equal power and frequency response with an integrated amplifier. 

The wireless 4-Pin input and higher peak power, and maximum SPL make the SPL-120 suitable for family karaoke or movie theater that requires robust audio and deep bass sound. 

For these reasons, the SPL-120 is the better device to opt for in terms of audio performance. But the difference is not that noticeable through everyday uses. Therefore the core difference lies in their cabinet texture and design. 

Just go for the device that suits your room’s interior and matches the surrounding furniture.
