Short answer: the Micca MB42X G2. It ranks #64 of 179 bookshelf speakers by sound quality, rated 3.6/5, at $97.99; the Aperion Audio Novus N5B ranks #69, rated 3.5/5, and costs $449.25, so there is not much of a tradeoff to weigh.
The Aperion Audio Novus N5B is the deeper-bass option. Compact front ported bookshelf speakers with an aramid woofer, a silk dome tweeter and inserts for wall mounting. Its bass reaches about 58.6Hz before falling 3dB, against 68.8Hz for the Micca MB42X G2. The catch: Measured sensitivity is very low at about 81.6dB and the 4-ohm load benefits from a capable amplifier.
The case for the Micca MB42X G2: Very inexpensive compact bookshelf speakers with a proper crossover and broad dispersion, a strong match for a basic amp and subwoofer. The catch: The 58Hz measured extension and small woofer limit deep bass and maximum output.
Buy the Micca MB42X G2. It is rated higher for sound quality than the Aperion Audio Novus N5B and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
