Electro-Voice ETX-18SPchat_bubble_outlineFrom real comments

Cardioid mode requires an array, not just one box. Multiple commenters explain that the ETX-18SP's cardioid mode only functions when two or more subs are stacked together, with one unit physically flipped 180 degrees and switched to cardioid while the other stays normal. This uses phase cancellation to cut bass at the rear of the stack and push it toward the crowd, but it reduces overall low-end output and doesn't work with a single standalone sub.

Weight is a real concern for solo operators. At least one former owner notes that the ETX-18SP's weight was a practical drawback for a one-person operation, prompting them to switch to lighter gear they could manage alone. This suggests the sub, while capable, may not suit users without help loading and transporting equipment, and a ramp was even suggested to ease handling.

Long-term reports are mixed between satisfaction and failure. One user who has owned the ETX-18SP for a couple of years says they love it and call it a good choice, while another reports the woofers went bad twice, the sub clips early cutting off bass, and the tops didn't live up to advertised wattage claims. That second user ultimately switched to a competing brand, citing disappointment with EV's performance relative to its marketing.
