Questions and answers
- Is the Forte IV worth the extra money over the Heresy IV?
- Only if you want deep bass without a subwoofer. The Forte IV's passive radiator reaches much lower. Otherwise the Heresy IV uses the same midrange driver and tweeter for far less.
- Which is better for a small room?
- The Heresy IV. Its smaller cabinet and removable slant riser make placement easier. The Forte IV is a large floorstander that needs more space.
- Do I need a subwoofer with the Heresy IV?
- For music, many listeners are fine without one. For home theater or organ and electronic music, a subwoofer fills in below 48 Hz.
- Which one plays louder with a low-power amp?
- Both are high-efficiency horn speakers that run loud on modest power. The Heresy IV is rated at 100 W max, and the Forte IV is similarly efficient.
- Which lasts longer?
- Both are built in Hope, Arkansas with wood veneer cabinets. The Heresy IV carries a 10-year warranty, and the Forte IV is built to the same Heritage standard.
