Short answer: the Micca MB42X G2. It ranks #63 of 160 bookshelf speakers by sound quality, rated 3.6/5, at $97.99; the Aperion Audio Novus N5B ranks #67, 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 pair with a silk-dome tweeter, 5.25-inch aramid woofer and wall-mount inserts. 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: An inexpensive compact passive speaker with a proper crossover and broad, useful dispersion. 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.

Aperion Audio Novus N5B: $449.25 per pair Aperion Audio eBay
Same family: the Aperion Audio Novus N5T (floorstanding, rated 3.8/5) and the Aperion Audio Novus N5C (center, rated 3.6/5).
Pros: Compact front-ported bookshelf pair with a silk-dome tweeter, 5.25-inch aramid woofer and wall-mount inserts. Erin’s data shows a nearly flat +0.02dB/octave tonal slope, 47Hz extension and a 5.98 preference score with a subwoofer. Measured bass extension of 58.6Hz (-3dB), with a measured sensitivity of 85dB.
Cons: Measured sensitivity is very low at about 81.6dB and the 4-ohm load benefits from a capable amplifier. On-axis smoothness (0.221) is only fair, predicted in-room smoothness is poor at 0.160, and the raw no-subwoofer preference score is 3.76.

Micca MB42X G2: $97.99 per pair Amazon eBay
Older model: the Micca MB42X Mark III (ranked lower, rated 3.2/5).
Same family: the Micca MB42X-C G2 (center, estimated 3.5/5).
Pros: An inexpensive compact passive speaker with a proper crossover and broad, useful dispersion. Its local Spinorama result reaches 6.80 with a subwoofer from a 4.18 raw score, excellent value when paired with basic amplification. Measured bass extension of 68.8Hz (-3dB), with a measured sensitivity of 82.7dB.
Cons: The 58Hz measured extension and small woofer limit deep bass and maximum output. Four-ohm loading can be demanding for the cheapest mini amplifiers, and the vinyl cabinet is plainly finished.
