How important are the Speaker Cabinets?


I am curious to learn about speaker cabinet design and how important does the cabinet contribute to the overall sound. Does the weight of the cabinet make a difference. For instance a floor standing speaker that weighs 200 pound versus one that weighs 60 pounds or 300. Is there any correlation to weight and sound? How about material?

How much are you paying for the cabinet versus the drivers on an expensive pair of speakers?

Just curious?

Thanks.

"baltic birch ply is 1 of the best materials"

I though all plywoods have the potential to delaminate and vibrate internally and thus should be avoided ?

There are lots of ways to laminate. I used to work in sales at a piano rebuilding store. I recognize the stock used in the cabinets of Magico, NuForce, and Lominchay--commonly called Baltic birch--as the same material the piano shop used for pinblocks. I've held the raw stock in my hands. This was a premium rebuilding shop and this stock was the best available for pinblocks, which have to be able to hold over 200 threaded steel pegs in a grand piano to anchor all the strings and enable them to be tuned. This stuff does not come apart!

In fact, this stock is very heavy, and certainly inert, because more of the weight is from the resin that holds it together than from the wood itself. It would be an excellent speaker cab material--very rigid, strong, cohesive, and inert.
Drew,

Thanks for the link. The article proves what most people inherently feel or know to be true (if they are ruthlessly honest about it): aesthetics is more important than sound quality to most audiophiles.

This is why audiophile manufacturers make costly and beautifully finished speaker cabinets and stuff them with very cheap but pretty looking drivers...sound is awful but nobody notices.

In contrast a sturdy but obviously DIY speaker armed with expensive drivers looks like a POS and will be judged that way even if it sounds fantastic.
Shadorne, the article does not prove that looks are more important than sound quality. The conclusion I draw is that non-sonic factors clearly influence a listener's opinion of sound quality. Those non-sonic factors could be size, brand name, number of drivers, design elements, build quality and appearance.

Audiophiles are a varied group, but one thing I've learned from looking at the all out assault systems here is that, if money is not an obstacle, a great system can look great as well as sound great.
Re: the purchase motivation of expensive loudspeakers.

If you place a pair of large floorstanders in a living room, they are effectively something between furniture and sculpture - in addition to the last link in the sound system. Thus, they have 2 functions: visual and aural. As you spend more money, you would expect the product to perform both functions "better". Of course, in both cases, "better" may be the subject of some debate. Given the realities of the overall market, how else would you expect it to be?

BTW, I don't dismiss reverse psychology. I'm sure that someone out there makes an "ugly" megabuck speaker specifically to convey that all the cost is dedicated to the "aural" function and little (to none) to the "visual".
Given the realities of the "lunatic fringe" (BTW, I could reasonably be classified as either part of, or close to, that crowd) how else would you expect it to be?
