highest Sensitivity subs

[Amit_112dB]

Can any one tell me wats the world highest sensitivy sub, just sub only without horns
well i found this JBL P1222 which sayz 97dB SPL @ 400rms aprox350$

http://www.jbl.com/car/products/pro...age=ENG&Country=US&Region=USA&cat=SUB&ser=POS

i guess its one of the most efficient n highest SPL i have ever seen in spec. of any sub

Have u seen anything better than this...

That sensitivity is most likely derived from the two 2ohm coils in parallel - so, a 1 ohm load. Also, it's not referenced to 1 watt - but to 2.83v.

The real spec at '1 watt' is probably much much less.

The highest I've seen was the Aura 1808's ~98 dB/W/m measured some years ago, but no longer made AFAIK.

if its at 1ohm, u have to reduce 9db, so its 97-9 =which would be too less, JBL site just said 2.83v at 1 meter it does not say 1ohm or 2 ohm or 8ohm [], not a fair thing

And of course, all the less significant out there. Just to name a small few..

And let's not forget some of the 24 inchers!..

^ Atomic ELE24 is only a measly 95.3dB and dual 4 ohm, but with 19.6Hz Fs and 15mm Xmax though.

..I guess this is all different though.
I think I've seen quite a few claiming over 100dB too, with response graphs (as if that really means anything).

Here is a company that has some Ciare HW450 to give away for an intersting price:

Here are the specs:

A pair of those hw450s in a cabinet would make a nice "little" sub speaker.
About 104db/2.83V/m will make a bit of noise around the neighbourhood.

 

[el`Ol]

I was mighty impressed by the 97dB of the JBL, but then I realized it is 2.83V at 2Ohm, so you have to subtract 6dB.

 

[Cal Weldon]

That Ciare looks like nothing more than a lightweight PA woofer. Anything but a "sub". Down 20 dB at the 25Hz Fs.

Another audio scam, P= V^2/R = 2.83^2/1 = ~8 watts when responsible companies use 1 watt for efficiency.

 

[Bricolo]

http://www.phlaudio.com/ has some nice high efficiency units

 

[stusigpi]

Weren't there some cerwin vega's at 96 1 watt/1meter

You can't break the law---

Any sub with high SPL and low Fs must have a very large VAS (or low impedence)--

So if you don't mind having a huge enclosure, it would probably be an 18" pro sound "sub" that would qualify as "plays loudest".

I can't tell you how many hours I spent looking over specs.....

Quite rite, all high sensitivity subs are bigger and powerfull than the normal subs, i tried to find a small small sub with 94+ spl but i guess its not here on earth..

 

[el`Ol]

Not really small and not really sub, but maybe an acceptable compromize:
