Thank you to gregm3 and to br3098 for their comments.
To br3098. You mention that you "used to be" a Larsen dealer; If so, did you drop the line and why.
My previous comment about the wide price difference between the models 4.2 and 6.2 was only to ask and highlight what made the 6.2 more expensive by almost $2100. I e-mailed Michael Vamos from Audio Skies and ask him the same question;. he claimed the materials in the drivers and cross over network were of higher quality. The question always is:... do price differences accounted for by better construction materials necessarily produce a better sounding speaker to the one below it in price? I would give the 6.2 more consideration than 4.2 if I was convinced that its performance warranted the extra dollars.
BTW, Mr. Vamos referred me to a dealer in Los Angeles called "Common Wave" that carries Larsen speakers and is closer to where I live.
Thank you for you comments and advice
