"American Sound" Speakers


There's a lot of discussion about and descriptions of the 'British/BBC' sound here, and I'm pretty clear on what that is. As a Rega owner, and fan of Avalon and Harbeth, it's safe to say that this is my preferred sound at my current stage of development.

But what comprises the "American Sound?" What are some example brands or specific speakers that exemplify this sound?

To name a few more:

Wilson, Devore, Western Electric, Altec, Jensen, Von Schweikert, Dunlavy, Revel, Meadowlark, Eggleston, Joseph Audio, Verity, Zu Audio, Magico.

Historically, I always think of older JBLs as representative of stereotypical "American" sound. Prominent bass and lower "presence region" treble (relative to the midrange) and very dynamic sounding. Sort of the inverse of classic "British" sound.

I agree that, over time, most of these tags have become dated and are no longer particularly apllicable to contemporary speakers.

The most direct answer is this: The British sound was developed at a particular moment in time, by a particular scientific study, paid for by a particular government. This study presented facts and numbers in no uncertain terms and has had a great influence on everything acoustic and manufactured for this hobby. Albeit not the last word on anything.

The American sound on the other hand has been formed just as everyone has mentioned above. Entreprenuers spending their own money to produce a product unlike anyone else's. A product that satisfies what they want in a speaker and that has truly earned the praise and success they deserve in the marketplace. God Bless America and every other free society where a miracle like this can take place.
The West Coast Sound (American Sound) was developed as a response to the motion picture industry. Since sound tracks became part of the motion picture industry there was a demand for efficient systems which could fill large theaters with clear, undistorted and dramatic sound. There were no options but the use of large horn loaded systems. JBL, Altec & Stephens were leaders on the west coast. The East Coast Sound was still dominated by British design speakers or USA manufactures attempting to duplicate the British sound.
