FAQ

Q1:What size amplifier do I need for this speaker? Is it hard to match?

A1: It's very amplifier-friendly. With an input sensitivity of 0.9Vrms, it's "efficient" and can get loud easily with most standard professional amplifiers. Its rated power handling is 700W, so simply pair it with a reliable amplifier that delivers between 700-1400W per channel (into 4-8 ohms). This covers a wide range of common amplifier models.

Q2:How is the bass performance? Is 37Hz low enough?

A2: A 37Hz low-frequency extension is excellent for a 15-inch speaker. It delivers solid and punchy bass, capable of clearly reproducing details from kick drums and bass guitars. Combined with its vented (bass reflex) box design, it offers high bass efficiency and plenty of impact, even in outdoor or large indoor spaces.

Q3: Is the enclosure durable? Will it get damaged easily with frequent transport or outdoor use?

A3:  Durability is a key design focus. The cabinet is made of rugged multiply plywood, resistant to impact and warping. The finish provides dual protection: a water-based primer topped with an extremely tough, scratch-resistant polyurea coating. This makes it highly resistant to bumps during shipping, weather exposure outdoors, and general wear and tear from live use.
