You can improve a paper cone woofer by giving it a couple coats (or more, but be careful) of puzzlecoat.

There are lots & lots of good poly/kevlar (poly by itself is not great) woofers. The BluePrints mentioned, the Lambda built Stryke woofers or the more expensive TC Sounds ones, , Adire Audio has a very good range, and more.

My resoning for disliking foam surrounds is simply aesthetic. I think they are ugly, but I doubt that they degrade performance. I recently bought some little audax 6.5 inchers to replace a burned out woofer in my cousin's bookshelf speakers. It said in the ad that they had rubber surrounds, and it turns out that they had foam. they sound fine, of course, but I was a little peeved. Is it possible to replace a foam surround with a rubber one?

I don't think I would actually do this, I am just pondering the idea.

Default Ariels

I wouldn't take 'Tranducers' word for it. It seems that he built a really old version of the Ariels... and for some reason, he has a huge beef with Lynn Olson. I'm don't believe everything he says about him or his speakers, especially since he is saying these things without Lynn around to defend himself. I for one have built the latest Ariels with top notch crossover componensts and can say they are a fine sounding speakers. Just a tad rolled off on the highs, and maybe not the end-all in speed and transparency when compared against FR drivers. But they are very room friendly and sound wonderfully musical and warm/lush and a good match for the PP 300B I'm using. And this is with no tweaking of the crossover or line stuffing. I'm sure I can bring up the tweeter level if I want to, but the have sounded so good for the last 3 years, I have never gotten around to tweaking them.
I think they have a very rich and glorious midrange with no "hole" that I can hear... Just a little slow and less detailed as I said when compared against good FR's.

Take note in Tranny quotes his current (bookshelf) speaker as measuring flat. I for one do not consider measurments when I'm choosing a speaker. It either sounds good or it doesn't. There are plenty of flat speakers that sound dead, and plenty of non-flat ones that sound great... when done right.... Lowthers for one.
And multitudes of FR's for others. I don't think Tranny's Ariels were "done right".

Slice

Go to Lynn Olson's Ariel site, read the section on good bass, it will be under active crossover in the index, it will give you something to think about when chosing your subwoofer.

Default sub drivers

I took Lynn's comments on sub drivers to heart. Put an alunimum cone 12" driver (Alumapro Alchemy) in my DIY tranmission line sub cabinet. It kicks with extremely clean, undistorted bass and dissapears with most mated mains.

With it, I'm using a NHT SA-3 250W class-D sub amp w/built-in crossover with the normal adjustable gain, phase, x-over, etc.

Next best thing for sub driver cone material besides aluminum, kevlar and other expensive stuff, is treated paper.

This looks like it could be a good one for the money... low Fs and 94db!

good luck .

The MB quart looks like an awesome woofer, but no way it get 94dB at the frequencies you'll be using it at. It may get 90, which isn't bad.

Oh, I forgot. It's 94db only with both 4 ohm coils running... making it 2 ohms. Good stuff *if* your amp can handle that.
