Yesterday evening YG had a tour for the Colorado Audio Society (CAS) and I'd like to thank YG and CAS for this great opportunity to check out one of the world's best speaker manufacturers.
We started with a multimedia presentation of YG's production so we can see all of the key parts and how they are manufactured, as it all doesn't go down at once... this evening they were machining PCBs, which they do using CNC machines and sheets of pure copper so the copper can be thicker vs traditional methods.
For those unfamiliar with YG, their speakers are manufactured primarily out of aluminum, including cabinets, driver cones and many other parts... the CNC machines run 20 hours a day, 7 days a week in order to produce these speakers! So everything is made in-house and to very tight specs. They even wind their own inductors, both air and iron core. AFAIK the only thing in a YG speaker not made in-house are the capacitors and resistors in the crossovers.
The goal is simple: perfection at any cost. Drivers are all made in house with woofer and midrange cones made out of blocks of aluminum. Their new 21" subwoofer cone starts out as a 60 lb block of metal. Their tweeter is a silk dome, but is supported by an aluminum "airframe" that weighs 30 mg and held to 5 microns tolerance. It is able to withstand greater g forces vs a beryllium dome without the breakup issues of a metal dome. The crossovers have been designed to optimize both frequency response as well as achieve perfect phase response. The speakers maintain a wide dispersion pattern, even the MTM model has very even dispersion over 45 degrees in the vertical plane.
I've remarked before about YG's sound and last evening's listening reinforces my previous impressions of a speaker that has exceptional coherence and minimal coloration. Resolution and microdynamics are exceptional, and the speakers also do a fantastic job reproducing large scale music without distortion, at least at moderate volume levels... but I didn't have an opportunity to listen at more realistic volumes, and I have never been able to test their abilities at higher SPLs. We did listen to one rock track at moderate volumes where you could notice visible excursion from the woofer, which is in a sealed cabinet. This is almost certainly going to be the limiting factor of this speaker system as far as SPLs, but YG is modular and you can always add more woofer, including the new 21" subwoofer that will play flat to 20 Hz and has a built-in 6kW amplifier. So, owners can start with the Sonya MTM module on a stand and eventually add the woofer cabinet, then go to the 4-cabinet setup, then add the subwoofer. The only downside is YG gear isn't cheap, so this might not work out for those with a budget. However, for those who want technical perfection and value what YG brings to the table, and don't need high SPL capabilities or need to fill a huge room, then the smaller YG speakers may be a great choice. You can certainly get more speaker for your money elsewhere, but it won't be as perfect as a YG speaker. ;) So I'd say this is really the only downside of YG's ethos, it isn't inexpensive... but OTOH you're getting more than a fancy cabinet and a carefully crafted story to justify the price. This is true cost-no-object engineering!

I went some years ago, it was great then but they have stepped it up since then. I wanted to attend last night but couldn't get out of work early enough. :(
