Some questions about the Lii Audio F15 please ...

I sometimes watch Chinese speakers on aliexpress. All speakers really have a high Qts. This doesn't correspond to the specification, as well as other parameters .
the specification,Qts=0.49,Fs=51.432 !!!(432)

really Qts=0.95,Fs=73,6Hz (!)
"My most sincere thanks to the seller! If it was possible to put more than five stars-would put ten! I ordered two speakers and one of them came with a strange marriage. In appearance, everything is whole, the suspension is soft, there is nothing in the gap. But the parameters of teal-smallle can not be measured-there is no resonance on the impedance chart. The rumor is that in addition to the main tone, a lot of harmonics are heard, so they seem louder than the main tone. Wrote to the seller, described the whole picture. Took the graphics from the second correct, recorded a video with a faulty. The seller agreed to send a replacement and here she finally came. With New Dean is ok, parameters are about the same as the first one-resonance frequency about 73,6Hz, impedance 4,2 Ohm, QMS 5,4, Qel 1,15, QTS 0,95. It's all cold, without warming up. The seller is very human thank you!!! 12 Nov 2020 10:18"

"The speakers are made very neat! The parameters, of course, are not at all those stated on the page. QTS = 0.8, FS = 55. AC up to 500Hz perfect, and further, as usual, begins the rise and "jumping". Within ± 10dB and up to 12 kHz. Further sharply down. No 20 kHz in the poem! And the distortions were pleased. Less than 1% after 100Hz. In general, the dynamics are good. Seller 5 stars! 02 Jul 2020 10:30"

I like mine on OBs, crossed at 100Hz to Goldwood 18"s. I had an impulse for convolving that worked with Daphile - made them sound even better - but Foobar tells me something about the sample rate isnt compatible...so I probably lost the files and suppose I just got used to listening to them as-is.

Frankly, after a year if ownership I never seem to be disappointed. Even movie and TV soundtracks (from the likes of PBS..) make me chuckle at how good they can sound - which of course contributes immensely to my enjoyment. Not sure if the wife/kid even get it in the same way I do. Oh well.

Percussion and Piano (a percussion instrument) seem to be their forte...besides throwing a really nice panoramic soundstage from the sweet spot. Glad to read others seem to like them too.

One can make a pink noise source from a cheap SD card reading ebay class D amp. Put that with Spectrum-eye iPhone app (or other phone RTA) is a decent, low, low cost intro to doing some measurements. Guaranteed to disappoint! ;')
