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.

Very important!! You don't want them if you want the most accurate sound:

Quad

Soundlab

Magnepan

Martin Logan (well some)

Viridian, you are absolutely right. A recording is an approximation of the original event at best. In room #1 we have components A,B, and C. The origninal recording engineer has listened to the playback and proclaimed it to be an excellent recreation of his work. Now we move A,B, and C to room #2 and the engineer listens again and proclaims the sound is too hard and steely. So, are the components accurate or not?
To the original OP, obviously the cabinet material/construction has a major influence in the sound. You can go from ultra rigid cabinets like Wilson to bending wave cabinets such as the Omnimon.
