very sensitive speakers

NED 209 · 15th January 2008, 02:09 AM

hi there, question id like to ask of you buffs, do you know of any speakers that weigh in around the 1.5kg (3.5lb) mark, that are very efficient, 96db on up?

im tryin to make the most of the 7 watts my amp32 puts out.

thanks,
ned .

always wanted to use that icon... i want to hammer out those beats

Out of curiosity, why is the driver's weight of importance?
Are you asking about drivers or an entire speaker system (enclosure, crossover, driver)?

its for a portable system. full range drivers

Well, the ever reliable, inexpensive and great sounding fostex fe126e weighs in at about a kilo each, but are only 93db efficient. There is this
Onkyo driver and costs only $3.50 each, 96db/w and judging from experience should weigh in around half kilo...keeping your weight limit in mind you can use up to three per side further raising output.

It would be easier to help you if you clearly defined your project. I consider my relatively huge Karlsons portable ever since I put handles on them

There are two ways to go:
*Take a stiff and expensive material, e.g. 6mm acrylate.
*Take thin ply and build resonating enclosures - will take some trial and error, since there are no simulation tools available.

ahhh, eight inch under a kilo and a half may be tough. Perhaps something vintage with small alnico magnets... Dave?

Efficiency of a loudspeaker is directly related to the size & the motor strength, and inversely proportional to the moving mass.

So to be efficient a speaker needs to be big, with a serious motor and a light cone. These also tend to want a horn enclosure to generate any bass.
