Short answer: the JBL 305P MKII. It ranks #18 of 108 powered bookshelf speakers by sound quality (rated 4.3/5) at $319 and is still sold new; the IK Multimedia iLoud MTM ranks #31 (rated 4.1/5) and is discontinued, so it is only an option used. The IK Multimedia iLoud MTM’s replacement, the IK Multimedia iLoud MTM MKII, is rated 4.2/5 at $699.99.
The case for the JBL 305P MKII: Budget studio monitors with balanced sound and wide coverage that keeps the stereo image stable across a desk. The catch: The 3.3dB midrange span and rising response show it is not perfectly neutral.
The case for the IK Multimedia iLoud MTM: A tiny studio monitor with good balance and calibration support for close listening where bigger monitors won’t fit. The tradeoff: The MTM arrangement makes listening height and orientation important, while bass below the low-50Hz region still needs support.
Buy the JBL 305P MKII. It is rated higher for sound quality and still sold new, while the IK Multimedia iLoud MTM is discontinued.
