Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.

Impedance dips to around 14 Ohm at around 10KHz, which means it'll draw less voltage there than anywhere else on its FR, which explains the 10KHz dip. It also means that a typical 2 Ohm output amplifier will slightly overdampen the 10 Khz region, resulting in slower-than-normal decay of those frequencies. Whether that produces desirable SQ or not... ¯\_(ツ)_/¯ Ideally, it looks like you will want to drive these through amps that have 1 Ohm or less output impedance.
The Campfire Audio Orion and Andromeda are between 4 and 8 ohms in the bass region - THAT'S bad news.
The shame to me isn't just that phone outputs are inconsistent and often higher than ideal - it's that theres usually no information about that, and also no information given about IEMs until measurements are taken, often just by hobbyists. The 64 Audio range is a great example, with most of them tuned for really high impedance you get with stage monitoring gear. But of course the consumer market didn't know that, and the impression of nearly the whole range was dark, bassy, and veiled to some. Thanks to junki for spreading this info specific to the K10. Will be interested to see if any of my sources have that effect.
