You can hear a full 4 way GOTO in this event next month.  Come down, stop by, enjoy and judge yourself, in person.

It looks like out friend MINGSU did make the show and did demonstrate a new setup with his Goto drivers. I think this is very good move for Goto as by Mingsu’s efforts they will market not only individual drivers but the actual sonic results that might be accomplished in a complete inhalation.

The new system looks like have back-loaded dipole bass twin, looks like hyperbolic 150Hz horn channel, next channel looks like 300Hz horn and a tweeters. All drivers are from Goto, I presume the bass drivers Goto as well.

What I see good in this installation. It look like this time they made an efforts to time-align the channel – this is new for Goto setup and I think the credit goes to Mingsu or to whoever he hire to assisted him. Also, it is very seldom that always moronic Goto users have brain to locate upper MF and tweeter vertically, in the way how Mingsu’s setup has. Mostly Goto users pile up the upper channels horizontally that makes as much sense as to design a better anchor in order a ship to go faster.

As the criticism of this setup I would note a creaming absents of MF channel. With horn you can’t not hide what is going on and size of the channel need to be GRADUALLY increased. The gradualness of the channel’s size change is not a panacea and it itself do not assure anything but it for sure give very high flexibility to moderate output of individual channel and to shape proper sound for the given environment. In the setup that Mingsu present if you need to add more output at let say an octave un an down to 1000Hz then you have absolutely no control.

Another major thing that I do not like is the design of the frame hat holds their upperbass channel or whatever region it covers. For sure it must not be angled but it is not what I mean. What I mean that it looks and feels ugly and very much non-functional. It feels like chicken-wire crap that we do in our basements for prototype sake. I do not know if Mingsu market the individual drivers or the entire setup but if he willing to present the System then, please, spend some efforts and to design the horn frame appropriately. The horn frame is hugely underestimated ingredient of multi-horn system and most of the DIYers do not get it. A proper horn frame is very inexpensive but VERY expensive in design decisions.  In addition to design a proper frame has HUGE disciplining effect to system owner and allows reevaluating many aspects of multi-horn system. Mingsu, or whoever behind him, need for sure to redo the frame for this setup.

I have no idea how it sound and I hope Mingsu will share his observation about the Sound he was able to achieve.
