Is The Overall Weight Of A Speaker Important?

I think you are setting up a false dichotomy, Rok2id. And by false I just mean incorrect, not implying purpose or making a value judgment. For example, #3 single driver vs multiple driver is very much mission dependent- if you are interested mostly in vocal and small ensembles, or if you value coherence over top and bottom extension, then single driver may be your cup of tea; but the mission is also dependent on the other components of the system. If you want to build your system around a flea watt valve amp, then a single driver or other high eff design is dictated, regardless of your musical preferences.

OTOH, if you want to achieve near realistic SPLs for orchestral music, then the "best" speaker may be a horn-loaded, multi-way design (if you fancy valve amps), but a large multi-way line source might fill the bill (if you want to achieve that w a moderate power class A ss amp.) If you've got to place the system in a multi-use (and multi-user) room, then that's probably going to rule out the Wilson Maxx or VS-9 type design so even if you need full range, you're probably looking at 2 way monitor or 3 way towers w a sub.

The "best" speaker design depends on the "mission", the "team", AND the end-user's weighting of the strengths and weaknesses of different design approaches. If there was one or 2 "best" high end speaker design approaches, then the high end market (which is by definition primarily sound quality driven) would weed out the inferior or highly user-dependent/mission-dependent designs and relegate them to the fringes. Of course, one could argue that the overall consumer market has already done that w the "the "conventional" rectangular, taller than it is wide, veneer-covered mdf box housing a 2 or 3 way complement of dynamic drivers" I mentioned above, which is clearly the "best" design for the majority of users (said only slightly tongue in cheek).

As for me, I say viva la difference! That's part of the fun of the gear side of the hobby, seeing how different combinations work to provide a satisfying home audio experience. Of course, I am completely ignoring the implementation side of the equation. I am sure that certain design choices are "easier" to implement satisfactorily than others, although I would be the first to admit that I do not have the technical knowledge to speculate about which those are. Maybe Duke or Johnk or Atmasphere or some of the other speaker or electronic designers could chime in and educate us on that issue.

To the OP- great thread, it's obviously made me think about this quite a bit. Thx.

Sorry for rambling on further, but there may be something to the weight idea. Similar to those who say that weight of an amp also correlates w SQ, due to importance of power supply, energy storage and output xformers, all of which come w significant weight. The laws of physics dictate that large boxes, large drivers, and/or large magnets are typically required to achieve an acceptable compromise btwn efficiency and frequency extension. Now there are some designers who are clever enough to provide at least the subjective impression of near full range extension w smaller boxes or lighter weigh panel designs, but you've still got to move air to make sound; and lots of it at low frequencies.

Not per se. But it may be indicative of things the designer has done that is important.

The best speaker I have ever heard is a smallish stand-mount two way where each speaker weighs nearly 50kg. The reason is is its made out of HD3 and lined internally with 3/4 copper plate to reduce resonances.

If you come across a speaker that weighs a bomb there is a reason and that is usually positive for the speakers performance.

Thanks

Swampwalker:

Your comments have changed the way I think about it. I was thinking that every speaker maker was trying to reach the holy grail or 'perfect' speaker. I now see your point, that speakers have different 'missions'. Just like cars, aircraft and every other product.

Thanks for the post.

Rega makes lightweight speakers, they claim excess weight just stores unwanted energy, same claim as their TT's.
I don't know if thats true, but I do know their speakers sound very good.
