FAST FORE -WORD
ast night I had dinner with Ken Kantor, an interesting fellow who is Vice President, Technology, for Now Hear This, one of the speaker making divisions of International Jensen. Ken said several things worth passing along during the course of describing how the price had been determined for NHT's new 3.3 speaker. While most audiophiles are quite knowledgeable about many engineering and technology topics, says Ken, "this group of inquisitive and opinionated people seems generally oblivious to the economic and business factors that shape the audio industry." While I personally find that many audiophiles and industry engineering types have something akin to disdain for business questions, it never ceases to surprise me how poorly these same people understand how retail prices are arrived at. They seem to think that the best -performing products, too often confused with the highest priced ones, are the ones that sell best. Kantor makes the point that "audio companies vary widely in size, with American brands alone varying by a factor of more than 1,000 in the number of people they employ, number of units shipped each month, and the total income generated." Obviously, a company at the big end of this spectrum is going to play by different rules than little ones. Basically, there are two ways of determining price structure, says Kantoroverhead driven and materials driven. Big manufacturers commonly start with a "bill of materials," and parts costs forms the
basis for most of their thought process. To the price of woofer, tweeter, crossover, box, carton, etc., is added labor, though this usually is a minor percentage of the total. "Ultimately," says Kantor, "the dealer price is simply a linear multiple of the parts plus labor, usually just about a factor of two. If parts and labor equal $100 a pair, then the dealer pays $200, more or less, and the customer sees a Manufacturer Suggested Retail Price of $400."
"But Ken," I said at one point, "how about the folks who think they are in business just to make the very best speakers they can? It looks to me that they ignore costs and mark-up ratios. Their prices appear to indicate some inflated notion of how 'great' their speaker is. How do they price?"
"The smaller companies pay most attention to overhead, to what it costs them to survive," responded Kantor. "It doesn't really matter what the box costs, because usually this is a labor of love. Market reality is that they can sell, say, 30 pairs of speakers a month, which really isn't an unusual number. Let's say, too, that there's six people with modest salaries, about $15,000 a month, but even adding rent, phone, utilities, ads, supplies, it's just $30,000 a month to keep the doors open. At 30 pairs a month, it doesn't matter whether the bill of materials comes to $100 or $200, but if the company can't get the dealer to pay $1,000 for the speakers, they need a new line of business."
There are a lot of things that fall out of this sort of analysis-such as why there are so few labors of love on the market and so many middle-of-the-road speakers. And why the Law of Diminishing Returns seems to have such a long upward curve with so few really good values. But I think we'll leave them for another time.
