Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

Omega makes great speakers and Louis is great to talk to.
Also has worst service I have ever had in 50 years in audio.

^ They certainly take a long time to deliver. Hopefully I won’t have any service needs. Do love the way they sound! 

Another full range speaker company getting ravs is the Lii Audio. The 15 and the best 10 inch drivers are 97-99db sensitive....made quite well. People on the Decware forum are going crazy over them. Just talked to a friend who likes his Lii F-15s better than his quad amped crazy system. You can get a pair of the F-15s for $400 plus shipping. The best 10 incher is $1000 a pair plus shipping and you can get the 10 inchers delivered to your home for $3K in serious speaker cabinets that let them play down to 30Hz. Are these as good as the Cubes? I hope not considering the price difference.....but, what if they are 90% as good? No Lowther shout....no peakiness has been reported. Of course, they need the usual several hundred hours of break in. According to those that have heard the 10 and the 15....the 10 is more articulate but the 15 is more fun to listen to (more balls).

You could mount a 15 and a 10 on an open baffle and put a coil on the 15 and a cap on the 10 so they are crossed over around 3-4 hundred cycles and you would get the balls of the big one and the more articulation of the smaller one and still the whole shebang is 97+db efficient. A single stack of great caps in series with the 10 would not limit their sound (you know Clarity cap CMRs bypassed by copper foils or better). Another way to run these two would be to use a tube amp on the 10 that has a very small coupling cap in it......That way you have a natural roll off of bass.....and you have a less expensive super sounding cap in the amp. This way you have zero xover again on the 10 incher.  Then run another amp on the woofs. Pretty cool stuff.

Ricevs,

I have followed F-15's development on the Decware forum and it does seem like everyone has raved about the sound and the quality of the 10" and 15" driver.  Their prices are more than reasonable and worth a strong consideration.

Considering the acknowledged superb sound quality of the Nenuphar,  if Lii  Audio drivers approach 90% of their performance that would be some feat given the cost differential. I hav6no idea if this is a possibility. Obviously someone who has access to both would have to compare them and submit a listening impression.

In the big picture the more of these types of high quality higher sensitivity drivers that are easy to drive the better. Match them with excellent quality low power amplifiers and you'll have the recipe for really natural and emotionally involving/organic sound. This is a good path to travel.
