RE: how on earth could that be time aligned?

Hello Angelo,

Goto drivers have surprinsigly goods sonic results when we consider the quasi artisanal work (the presence of irregularities on the surface of the diaphragms and the suspensions is often questionnable).

You have to know also that Goto doesn't use any measurement method in order to test, select, pair their loudspeakers.

But an excellent sounding system using Goto drivers cannot, IMHO, be obtained unless you use a minimum of 4/5 ways per channel...

The loudspeaker used in the AvantGarde (Community 200 or OEM...) is probably chosen in order to fit with their bass loudspeaker. While there is no phase plug, a little bit of compression is obtained between the outer part of the driver, the suspension and the casing. From the absence of large compression ratio a larger dispacement of the diaphragm results and then a quite high level of distortion (compared to a driver like the JBL245x by example) and a bell shaped frequency response curve. If you use a bit of equalization between 500Hz and 3000Hz then the efficiency fall to 105 or less. IMHO the rear cavity is also too small.

One may notice, that drivers without a true phase plug and using a low compression ratio are also used by Goto but only for their bass drivers...


Best regards from Paris,
