Lii Audio H 1502 15 inch coaxial drivers/tea strainer!

[THOMO]

These look interesting.

There is not much information on exactly what the centre coaxial mid/tweeter is but it looks interesting!

It seems an adjustable crossover is included in the price.

@MattyW had a few words on his Platinum 10 thread yesterday, about similar Lii Audio drivers, I think.

May be worth checking out?

If you do get these I'm interested to hear how you like them. Just remember that Lii Song and Lii Audio (Aliexpress, Tabao etc) are actually two separate companies.... Lii Song split from Lii Audio back in 2018. Their Silver and Platinum drivers are their own designs though F and Fast series are based upon Lii Audio designs. To confuse matters Lii Song operate off lii-audio.com. Really hope they change that at some point as its confusing for most.

 

That said, if I had a use for the Lii Audio coax drivers I'd give them a try as they're an interesting driver for sure.

It would be nice to have more information about what the tea strainer driver is .Maybe some of our Chinese speaking members can help finding  that out?

[MattyW]

You need to contact the chap via AliExpress as Lii Audio, the domestic company has no website of their own. Lii Audio has no current affiliation with Lii Song, even though Lii Song have the right to the Lii Audio brand internationally.

Hello all, I think this thread is worth reviving since I also couldn't find much information on them. So, about a year ago I bought a pair of these to see what they sounded like.  I just installed mine yesterday in a pair of Electro-Voice Regency 1st editon cabinets with the extra rear loaded horn baffles and rear board behind the woofer. First of all, for the money I think these sound fantastic.  The bass from these is impressive and they're very clear.  The bass may have something to do with the cabinets, however the Altec 605's I had previously in the cabinets didn't have as much bass weight to them.  I have the horns set to about 45 on the pots.  They make poor recordings sound poor and good recordings great which is exactly what a speaker should do.  The "Tea strainer" looks to be a close copy of the Jensen H-510.  These are called acoustic lens' and were common with other manufacturers back in the day with the most widely known ones being from JBL ("the potato mashers").  Stromberg-Carlson also used them on their RF-475 models.  On this speaker I think it provides a more off axis dispersed sound which provides a larger sweet spot, but if you sit directly in between them, you still get the "focused" sound all of these coaxial type drivers are known for.  The crossovers are also bi-ampable if that's your thing.  I am powering them with a 16 watt per channel tube amplifier and they get plenty loud enough. Overall, I am pleased with them especially for the cost.  

 

This is the write up from them about the speaker which indicates that the tweeter is a horn loaded polymer compression type driver:

 

The new medium and high-end 15 inch 2-frequency coaxial horn H1502 launched by Lii Audio. The rear compressed 50 core polymer film tweeter, coupled with the front acoustic lens horn, makes the overall sound smooth and smooth. The medium frequency texture is very good, and the vocal instrumental music plays well, which is very suitable for home music listening.

 

*The H1502 frequency division point is about 1000HZ, avoiding the most sensitive 1200-3500HZ area of the human ear. This area is also the range of most middle frequency domains (vocal instrumental music). The frequency division point of many small two-way speakers is basically within this sensitive range due to the speaker performance, so the unnatural sound is one of the reasons why there is no full frequency speaker.

 

*The H1502 bass cone has good smoothness. The bass uses a short voice coil design, which is very easy to push. It does not require high power of the power amplifier. The dynamics are excellent, and the large-scale music is as stable as Mount Tai. The texture of vocal instrumental music is very good. The frequency divider is equipped with a treble attenuator, which can adjust the proportion of treble and bass appropriately according to your listening taste, which is very convenient. In the parameter diagram, different effects of the third gear are displayed (50-60-90 scale).

About time someone wrote about these. It sounds like they're rather special. I truly wish they'd bring out a 12" version of these though so I can replace the drivers in the Markgo Gravity Coax-12 speakers I'll be placing in my home theatre room once the home is built. I believe these would be a genuine step up over the stock drivers.

 

I'm a big fan of fullrange and coaxials driver speakers. They simply deliver something that 2 and 3 way speaker designs cannot. Of course the inverse is also true 

 

I love your listening room by the way. A lovely retro vibe to it. I'm attempting to achieve a tasteful blend of heritage styles into our upcoming home build with a fusion of Art Deco, Tuscan and French influences with a modern twist achieving something still stylish but also relaxed and airy. I'm hoping I pull it off fiven no designers involved..... Just the architect. Though off topic I'd love to see more photos of your home itself if that's not obtrusive? It looks lovely.

I can't really say they're that much more special than any other driver, but i believe the frequency response listed to be fairly accurate without testing them with any sort of equipment.  They look like they're possibly sub quality to the Markgo speakers you're referring to. Honestly i think the Markgo might be the Chinese Tannoy...  China is now manufacturing the drivers for them...  The horn lens on the LII though might actually make them sound a bit different especially with a poly compression driver... They're probably smoother than something using a titanium or aluminum diaphragm. 

 

That's actually my parents house. I'll pass along your kind words.  I have so many speakers, that I have some at their house.  My father, a friend of mine and I rebuilt the cabinets as one of them was a newer model without all the intricate baffles and they've stayed at their house since they've been finished.  All my woodworking tools are over there. 

 

Lii audio does make a 12 inch coaxial: LII AUDIO 12 Inch Coaxial Speaker New C1202 Baffle Speaker 8ohm/60+40W (1PCS) - AliExpress\  It honestly looks like another fairly quality driver.

 

Also, Dayton audio has a 12 inch coaxial available on parts express for really cheap... ($75 USD) I'd be interested to see what that sounds like as well, although it doesn't look to have the same bass extension. I don't think I've heard a dayton speaker i didn't like.

Likewise, those Jensen type cabinets you have them in with the amps on top look great. I can imagine. The warm, easy sound of large efficient drivers.
