A true heavy weight by all accounts, the new SSA Zcon is absolutely a beast. Mega power and high output, the massive SSA Zcon is finally here. Incorporating an FEA optimized motor with a spiral CNC-machined solid pole piece, the Zcon has the technology and cooling to take some serious abuse with the ability to step up the cabin pressure to brutal levels.

Bringing to market our biggest motor ever, the Zcon has the motor strength for accurate cone control showing that this is not a one note wonder. The Zcon is at home in a moderate daily driver system as it is in a mega power competition system. Five sandwiched spiders and a large 3" - 4 layer aluminum coil, means the Zcon can handle the heaviest of hands on the volume knob for years to come. Right from the start, the Zcon is already in the top offerings on the market for the high end, big output daily driver sub woofers. You can be proud to own a SSA Zcon, as with the entire SSA speaker line up, it is designed, engineered, and built here in the USA.

Customer Reviews

First class people, first class service, first class product!

Low Hertz is a lot more than a website. I know I could reach out to them if I needed anything.
No, not just with products. You can always count on quality. But questions about the hobby. Low Hertz is a movement in Car Audio. Where your not judged but helped! So get in the movement with us.

The last 3 box designs I've purchase were all 150+ db certified in the lanes, your results may vary depending on vehicle and power but they definitely know what they're doing. Well worth the money !

Eric Feliciano

They designed my husbands box. Came out great. Never a disappointment when it comes to these guys. Definitely will be coming back for another build!
