Default 3" or less full range driver, no filter

I am sure this has been covered here many times, but I have not been able to get the search to work with me.


I am looking for a full range 3" driver, that will work well in a sealed 3 liter enclosure.


Preferably something that can run without a filter or crossover, maybe a simple first order just to keep it from blowing up at high volume.


It will be for a desktop speaker/boombox concept I am planning.


Here is a sketchup rendering:

The picture shows the Hivi B3S cone, I was thinking of that based on Zaph's page, but I am not set on that one since it is 8 ohm.


I am planning on running the amp6basic kit from www.41hz.com as the power for the whole setup.



Can someone help me find the ideal driver for my project? Trying to keep driver and crossover costs under $100 if possible.

Hi,

I think Aura NS3-193. 4 ohm or 8 ohm available.

Cheers,

Inertial

Looks like madisound is sold out of the 4 ohm Aura's


Any other decent sources? I would prefer the black cone if possible.


what about the TB 871's?

I think the NS3 is much more robust in fullrange application.

Maybe solen.ca have in stock ?

regards,

I have a couple of the NS3s in large cashew nut containers and they sound great, but you need to give them quite a few watts to make up for the low efficiency.
Also, the distortion goes up under 150hz, so crossing to a sub there really makes them sing.

Exactly,

The HiVi and AMP6 do not really match. Certainly not when your boombox is supposed to play loud.
I'd suggest a gainclone or AMP9

Well, the amp needs to be very small to fit in the "Bridge" between the 2 enclosures. Volume is not a big issue, since it will be used mostly as BGM at work, but from time to time it would be fun just to show off a DIY project, but output will often be less than 70db.


I was hoping to use the amp32 since it is so small, but I only have minimal experience with surface mount soldering, the amp6basic is getting a little large, but is well within my soldering abilities.


I also need an amp that will operate on 12v so that I can use a single powersupply to charge the iPod and power the amp. Also I plan on using a SMPS for ease of use and again for size constraints with the boombox.

You should seriously consider the Tang Band W3-871's.

I like the look of the w3-871's even though they are 8 ohm they have a MUCH higher sensitivity than the hivi's


Also they are only a little more expensive.


I just need to sell a few things around here so I can get the ball rolling on this project.

Not cheap, but some people say, that it sounds great!
