Well, it looks like my Avatar 115 B Neo can't quite handle what I'm dishin' her. Sounds awesome at low volumes, but try and push it (especially crossovered) and she gets some bad farts. FYI, it's rated for 200 watts at 4 ohms, and I'm pushing 450 per side. I guess I just want a recommendation for a new speaker. The enclosure is great; small, light, and big sound. Something that can handle 400-600 watts, 4 ohms, and might sound decent in that cabinet. No rush, but I'd like to get it working again, since it sounds so f'n incredible when I'm bi-amping it with a 4x10. Thanks for any replies gang.

Regarding Burdizzo's recommendation -



93 sensitivity isn't too impressive, but it oughtta do what you want it to do...

 

 

Look at where that 93 dB is rated, though.

 

Most companies rate their speakers at higher frequencies. Eminence, for instance gives their rating at 100 Hz.

 

The Selenium 93 dB rating is an average between 55 and 100 Hz. That's a realistic rating and is better than most other speakers in that range.

 

The other big selling point is the low Vas.

Maybe the original speaker that Dave installed in those?


I'm not sure, but I would guess a Delta 15 LF or just a Delta 15 by Eminence.

 

 

That was the original. Just not enough handling. Here's the specs:

OK, burdizzos. Tell me about Vas.

 

The way I understand it is that the Vas measurement is the volume in Litres required in a cab in order for it to reach its lowest usable frequencies. Is that correct?

Can you eleborate?

Damn expensive speaker, but it'll take anything I can throw at it and beg for more.


7.9 mm XMax!


w00t!

 

But it's only 94 dB at 200 Hz, where do you suppose it is at 55 Hz? ;)

 

 

That's also a great speaker in that cab, but it's expensive.

Nope, says right here it's at 97dB @ 200Hz.

 

It's in a 4 cubic ft enclosure.

According to Win ISD, the -3dB is at about 40Hz.

 

And that's at ~93dB! Not bad, if you ask me.

According to the response curve here, it stays constant 'til well below 40Hz.


That hump in the mid-range gives it a nice growl, too. Right now, I'm using it all by itself with great results.

 

 

 

Looks like 94 at 50, where did you get the 97 number?

Think I got it off of partsexpress, but I'm not sure. However, if you average it out using the sensitivity guide, I guess the median does come out around 97dB or so.

 

When Win ISD asks for the sensitivity, what should I put down? Instead of a hard number, Eminence gives you a bunch of data at different frequencies.

 

But you're right, all the important numbers are around 94dB.

 

It's a rockin' speaker. When it get it tuned with proper porting, it's going to kick even more ass. Right now, it just has the Avatar stock holes in the back.

In ISD, when you're having the program calculate optimum box dimentions, how do you change the paramters around to put more depth as opposed to height?

 

It seems bent on making an enclosure three stories high, and 6" deep! {censored}!
