wow thanks for the speedy response and information,seriously helpful. I really appreciate the input, cheers.
So sorry Phloored, I made a mistake, I intended to quote your comment not Faizal's. Thanks for the speedy response and information,seriously helpful. I really appreciate the input, cheers.
Looks cool. These things are beasts! Massive magnets. My music-8's are sounding really nice after over a hundred hours. They do change. I'm contemplating the cabinet build with the folded horn.
I have not heard the c 1202. The f-12's you bought are not really counterfeit, they are coupons that are clearly labeled lii-song. The coaxials will need some type of crossover.
What i can vouch for is my music 8's that i bought. I have heard clips of lii-audio's 15"coaxial and it sounded really good even in free air. That's all i got.

A guy who was supposed to market them outside of China for the original company broke away with similar designs and the same company name. Not sure that can be called anything but counterfeit. I know there are some odd customs in China - plagiarism is considered flattery, folks stand up and loudly answer calls during talks at conferences... and the Chinese have been stealing IP from other companies for years, so I am not super concerned that they are now doing the same thing to each other.
All that said, just wondering about quality and parameters of the Xizi Lii Audio drivers. FWIW, the crappy cell phone measurements I've made of the Lii-Song (maybe imitator is a better term?) F-12's are spot on with the published frequency response. Big drop around 15k - the 1202 doesn't have that drop - and I can put together a crossover and filter to tame the highs and get much closer to flat and better bass to boot. If the published figures are accurate...

Yes. They are in my opinion rudely resembling the original in labels and design. Call em counterfeit or whatever. I just didn't want to offend the huge amount of people who bought them and many who are satisfied with their purchase.
There is someone in this thread who has traveled to the xizi factory and seen their production area that's where they have an anacoic chamber they built for their measurements early on. He also has stated he went to the lii-song office and they had no such production set up. I'm so building and finishing my boxes for another project. From my experience, the xizi lii-audio drivers are very well constructed. From that perspective they are worth a shot.

Yes. Sorry, I'd overlooked that. Are those wiggly lines meant to indicate damping material?
Another question: Several here have mentioned that the Music-8 uses an alnico magnet and that is what the Amazon seller states. But the "Morning Glory" website specifies ceramic Y35. Which is correct?

Can you make a review after you finish your baffle ? i just heard them without baffle in china.
Well, I may be the first person to do so in the US, but I just ordered a pair of the Xizi Lii Audio C1202's to try in my open baffles.
I am not unhappy with the F-12's from Lii-Song (imitator) - they do sound very good in my baffles and I have the parts on the way to make a filter to tame the brightness in the upper mids and highs, but I feel like the upper sparkle just isn't there - especially apparent in certain jazz recording in the cymbal hits. I also want a bit more or a bit lower bass - and I want this without sacrificing the point source in my baffles.
If they work better, awesome!
Thanks! One of the simplest woodworking projects I've done, but came out super pretty. The baltic birch is 1.5" thick - two 0.75" pieces laminated together plus the 1/32" thickness of the front veneer. Modelled them up in sketchup first. There is a 5 degree rake at the bottom and top and the center of the phase plug is designed to be exactly ear level at 10 feet away with the Isoacoustics Gaia II feet installed. It's not American walnut, but Queensland walnut. There are some really nice flitches on ebay right now for pretty cheap. I will probably pick some more up before the price goes up and supply goes down. I have 6 full extra slices of this flitch right now and 6 other halves.
This one (below on ebay right now) is too short for something like this design, but man is it pretty... and almost all of the pieces are fairly well figured.
I just added my filter to cut the upper frequencies by 6 or 8 db and the speakers have much improved bass and are pretty nearly flat now. You can see how everything above about 12k is super rolled off though. I like the point source OB sound though, and love these baffles, so I pulled the trigger on the C1202's. Need to figure out a simple crossover now. I will ask the manufacturer how these work in parallel, but expecting him to say a xover is necessary. They do not give the full FR graph of the tweeter on their website. But, in must music, the F-12's are definitely much improved with my simple filter... (this still has the bass level increased on my preamp though... upper (red line) is the max music spl - sounds really good in the room - just lacks that upper sparkle with cymbal crashes.

Did you try to reverse the baffle to have the speaker closer to the floor to see if you get a better bass response ? (you might adjust the angle then).
No. I was modelling on this design, and the monolith concept was super important to me - and I hate the look of the 'betsy' baffles, so the shape was an important design consideration. Remember those monoliths from 2001 A Space Odyssey? I thought that would be a good name for these baffles...
I wouldn't say that with EQ, the bass was lacking before installing the filters (a 1.0mH coil and a 10 Ohm 10w resistor) - the mids and what there are of highs were just too exaggerated. The filter does a pretty good job taming them down somewhat. I need to run a frequency sweep at some point and that will give me a better idea, but listening to music - they do sound very nice.
