Technical Features That Set Reference Subwoofers Apart

High Excursion and Surround Design

One of the key features of Soundstream Reference subwoofers is their high excursion design, allowing the woofer cone to travel further with precision. This results in deeper bass output and better control, even at high volume levels.

The high roll surround used in both R1 and R3 models contributes to smooth excursion and enhanced durability, which is especially important in SPL or bass-heavy setups.

Voice Coil Configuration and Power Handling

These subwoofers feature dual voice coils (DVC), typically offered in 2-ohm and 4-ohm configurations. This gives installers and users flexibility in wiring options, especially when matching the subs with different amplifier loads.

With RMS power ratings often exceeding 500 watts and max power ratings reaching into the thousands, both the R3 and R1 series can be paired with a wide range of car amplifiers, including those used in competition-grade systems.
