Product-related questions and answers:
Q: What amplifier do I need for the EKX-18S?
A: You’ll need an amplifier delivering 400W continuous at 8 ohms, with headroom up to 1600W peak. Electro-Voice suggests their CPS or TG series for optimal pairing.
Q: Can I use this unit with active speakers?
A: Yes, it pairs well with active tops (e.g., EKX-12P) if you use an external crossover or the tops’ DSP to manage frequency separation.
Q: How does it compare to the EKX-18SP active subwoofer?
A: The EKX-18S is passive, requiring an external amp, while the EKX-18SP has a built-in 1300W amp and DSP. The EKX-18S offers more setup flexibility but no onboard processing.
Q: Is it suitable for outdoor gigs?
A: Yes, for temporary use, but it’s not weatherproof, keep it sheltered from rain and harsh weather.
Q: How many people can this subwoofer cover in a venue?
A: With proper amplification and tops, it can support 400-600 people in a medium venue, depending on room acoustics and setup.
Q: Does it come with cables or a pole?
A: No, it includes only the subwoofer, Speakon cables and poles (e.g., ASP-58) are sold separately.
Q: What warranty does it come with?
A: Electro-Voice typically offers a 3-year warranty on passive speakers, but check with DJKit for confirmation.
Q: Can I stack multiple EKX-18S units?
A: Yes, they can be stacked, but ensure secure placement, as they don’t interlock, side-by-side use is often more practical.
Q: How portable is this subwoofer?
A: At 31.8 kg (70.1 lbs) with handles, it’s manageable for short moves, but a trolley may be handy for longer distances.
Q: Will it distort at high volumes?
A: When matched with an appropriate amp within its 1600W peak rating, it delivers clean bass up to 134 dB SPL; overdriving it risks distortion or damage.
