Frequently Asked Questions:
1. What is the main benefit of a dual-driver subwoofer?
A dual-driver subwoofer uses two 18-inch speakers, which allows it to move much more air than a single-driver unit. This results in significantly louder and deeper bass that is ideal for large venues.
2. What is the difference between Rated and Peak power?
The Rated Power (1600W) is the continuous power the subwoofer can handle reliably over a long period. The Peak Power (3200W) is the maximum power it can hold for a very short moment, such as a strong bass hit.
3. What kind of amplifier do I need to use this subwoofer?
Since this is a passive subwoofer with an 8Ω impedance, you will need an external power amplifier that can provide at least 1600W of power at an 8Ω load to match its rated power.
4. How does its size and weight affect its use?
At 76kg, this is a heavy-duty subwoofer designed for high-performance. While the built-in handles and wheels facilitate movement, it is best suited for professional use, where it may be moved by two people or with professional equipment.
5. What is SPL, and why is 136dB significant?
SPL (Sound Pressure Level) measures how loud a speaker can get. A maximum SPL of 136dB is exceptionally high, meaning this subwoofer can produce powerful, physical bass that can be felt in a large venue.
