The EKX 18S, made by EV, is a fantastic sub and definitely worth purchasing! This sub is great for live application, both inside and out! They deliver a heavy 1600 watts of power and when paired with a couple of 15" speaker any environment will come alive with sound! The EKX 18S subwoofer is lightweight, portable, and durable as well. All in all a great sub and a product I recommend for people looking for quality!
