A brief introduction to the all new SSA Demon, but first a farewell to its predecessor. 

     Our very long running SSA Dcon has ridden off into the sunset, or at least taking a breather.  The SSA Dcon was our second subwoofer model we ever launched.  At the very beginning, we had the Icon and as it gained traction we saw there was a need for a pure SQ sub of more modest power rating than that the Icon.  So in early 2008, the first SSA Dcon was launched.  (The Xcon followed shortly after).  That being said, the Dcon was almost an immediate hit, with a long 2" copper coil (rarity to have one made in the USA) triple stack motor, rear vent.  The Dcon was very affordable, well made, quite efficient, clean across the entire range, and flexible with enclosure demands.  It is interesting as there are some SSA Family members who swear by their Dcon and will not give it up ever.  (It even became a favorite of some of the home audio crowd).  All that being said, the Dcon evolved a bit for its second generation, we made a leap forward in motor force moving to what is best described as a scaled down Xcon motor, with a large single slug, solid pole, and deeply bumped back plate, while beefing up the suspension and leads.  We were able to bring the power handling up 33% while not hurting the sound that made the Dcon successful.  There was a stretch of a few years, before we ran out of stock, that the SSA Dcon 12 was our all time best selling subwoofer.  So its existence was very important to SSA.  Well with changes in the market (read:customer demands and amps getting much cheaper), as well as sky rocketing material costs, building the Dcon in the USA no longer was an option, so production stopped early 2017 for both the Dcon (and Gcon) and inventory ran out later that year. 
     Late last year, due to the long lay off with out the Dcon (and Gcon), we started development of an updated Dcon at a new build house.  The quality and performance of our SSA Evil1 tweeters were above our expectations, so we decided to send more production to that same build house.   As we saw that the market slowed overall for modest power rated subs due to power getting cheaper and people wanting higher power handling subs, so the market began to really start heating up in the 500 - 1200 watt range, I knew we needed to address it.  There is an 8" model developed, but it will not make it this first production run.  
     The new model had to handle more power and have more xmax while not sacrificing the balanced and clean sound the Dcon had established for nearly a decade.  That meant larger motor, larger coil, more suspension, larger leads, thicker cone, taller surround, etc.  In the end, all of the changes that happened to the over all design, we could no longer call it a Dcon.  In sticking with the theme of the Evil, a model name that has become so well known, while respecting the Dcon, the Demon name was selected.  The Demon is a great blend of the previous Dcon and Xcon, both in design and appearance.  In prototype testing, the SSA Demon thrived smaller to mid-sized ported and mid-sized sealed enclosures.  The SSA Demon will start out in a 10" and 12" model size and they are on their way to our New York warehouse right now.  These are VERY conservatively rated.  I have the prototype in our old trusty RX330 and it is seeing over 1200 @ 4 ohm mono right now.

Do you have any more pics of the basket? I'm curious about cooling since there is no pole venting.

Any idea on xmax and power ratings?

Was there any break in time before measuring the parameters posted above? 

That thing appears to have a VERY light moving mass and stiff suspension.

I will have full specs up on the website soon.  Basket is the standard 12 spoke.  Cooling is coming through the base of the basket.  Same as our previous Dcon, previous Icon, previous Xcon, previous Zcon, previous Evil etc. ;)  





We are rating very conservative at 550 rms and specs are after break in.





Xmax right around 22-23mm

How would the 12" perform in a 1.5cf net tuned to 40hz using 4"x11.25" pvc?

I want to replace my Pioneer TS-W3003D4. 

I listen to metal most of the time so don't want to tune low. 

I can build a new box a little larger if needed.

Amp is JBL GTR-1001.

It will work.  That is a little higher than I personally prefer tuning, but it will still sound excellent.

Why would you not tune low for metal?? 40 Hz is going to be nasty without alot of eq.

because metal plays at a higher frequency range? 

I'm using an exterior port so I can add some pipe to make it longer.

So? a ported enclosure is prety much acting like a sealed enclosure an octave above tuning. So if you tune to 40 Hz at 80 hz you would be very similar to a selaed enclosure. Kick drums and bass shine from 50-80. I would recommend tuning lower like 30 hz. With a decent driver you would be surprised. Also the music would not be affected by the hump from tuning. Unless you like that bloated midbass sound then I guess tuning higher would be better.

If I did that then I will get people chiming in saying why am I tuning so low when metal doesn't have drops 99% of the time. 

I will try 32hz...or should i go 30hz?, How about 36hz? Geez...
