JBL 308P MkII.
JBL's Image Control Waveguide creates an expansive listening area, making the 308P MkII forgiving of imperfect positioning.
The Verdict.
Gavler Meta-Score
“The 308P MkII's wide sweet spot is its killer feature — it makes mixing more forgiving of imperfect room setup and positioning, which is the reality of most home studios. JBL's professional pedigree shines through in the waveguide technology, and the $299 price makes these monitors an outstanding value for anyone building their first serious monitoring setup.”

Global Critique
“Originally developed for JBL's flagship M2 Master Reference Monitor, the Image Control Waveguide ensures an acoustically seamless transition between the low- and high-frequency transducers and provides an immersive soundstage with precise imaging.”
“A great near- and midfield solution suitable for mixing music, editing video, or other tasks requiring monitoring accuracy — the patented Image Control Waveguide does an excellent job of delivering a wide sweet spot, and it punches well above its price point.”
“Dual 56 W Class-D amplifiers powering an 8-inch low-frequency woofer and a woven-composite 1-inch neodymium tweeter deliver a frequency response of 45 Hz to 20 kHz with a peak SPL of 112 dB — great sounding monitors with rich highs and tight bass at the price.”
