Both are bookshelf speakers in the same rough price tier, and both show up in our own speaker picks — but they're voiced almost opposite each other. The Klipsch uses a horn-loaded tweeter for a forward, dynamic sound typical of the brand; the Aperion uses a silk dome for something smoother and less in-your-face.
If you're building around other Klipsch Reference Premiere speakers — towers, a center channel, height speakers — the RP-600M II, so the whole system is voiced consistently rather than mixing product lines.
If you're starting fresh and want to hear both before committing, the Aperion Novus N6B — it ships direct with a 30-day in-home audition, so you can actually return it if the silk-dome voicing isn't for you, which the Klipsch's retail/Amazon purchase path doesn't offer.

The RP-600M II uses Klipsch's signature Tractrix horn tweeter paired with a copper-spun Cerametallic woofer — the same driver technology used across Klipsch's Reference Premiere towers, center channel, and height speakers. It's a forward, dynamic presentation that makes loud, dense moments in movies feel physical, which is exactly why it's the brand's signature sound.
The Novus N6B instead uses a German silk-dome tweeter over an aramid-fiber woofer — a smoother, less forward voicing than the horn-loaded Klipsch. Neither is objectively "better"; they're different design philosophies, and which one you prefer comes down to taste and the rest of your system.
The RP-600M II is sold through Amazon and other retail channels, like most mainstream speakers. The Novus N6B is sold direct from Aperion Audio — no dealer markup, and a 30-day in-home audition, meaning you can actually live with the speakers in your own room and send them back if the voicing isn't for you. That's a meaningfully lower-risk way to try a less familiar brand than a standard retail return window.
Horn-loaded, forward, and dynamic — the same voicing as Klipsch's towers, center, and height speakers.
