DD Audio 9921 21″ Subwoofer
(Afterpay Available In-store Only)
The 9900s are the go to subwoofers for the demanding bassaholic with a profound interest in physics. Entertaining minds will revel in the endless system design possibilities deliverable with these precision low-frequency devices.
Originally coined The Beast, the 9900s first appeared on the market in the early 2000s. It took a brief hiatus, but now it’s back and more beastly than ever. The latest iteration was developed in response to the recent explosion in ultra-low-frequency music. These subwoofers were designed to provide long-term power handling, with accuracy, and high excursion capabilities. It’s been optimized for a 1500 – 2500 watt power band with the ability able to handle bursts of up to 10,000 watts. One look at the 9900 motor and you see why we call it the beast. It boasts 3 inches of magnet cross-section, over a 10″ OD, and weighs in at 70 pounds (motor only). The traditionally tight DD magnet gap drives a 4″ flat wound aluminum voice coil to a peak excursion in excess of 3 inches while keeping enough turns in the gap to maintain power and control.
The 9900 Series features our Evolution Subwoofer Package (ESP). ESP equipped drivers sport larger diameter suspensions and deeper frames than standard subs and exclusive surround and cone designs. ESP subs are truly built to maximize performance in their designated size class.
The 9900 Series comes standard with an oversized dry finish black composite dust cap, red logo, and treated pulp cone, but it can be optioned out with alternative composite dust caps, composite cones, powder coated frames, supercharging, and a multitude of logo options to give your sub a personalized look and/or added performance for a specific application.

The boys were fantastic, so happy with with the service from start to finish. wouldn't go anywhere else. do yourself a favour and head into see them 1st, you won't go anywhere else. Thanks boys
Would highly recommend didn't charge me anything for the checkup on the audio system since it was a small problem. 10/10 they're awesome.
been there a few times for stereo install, dash cams, light bars etc awesome service. reasonable pricing. I will keep going back there. recommend 100%
Had my 79 series landcruiser in there for the works - door pods, speakers, apple car play head unit, under seat subs, amp, gme UHF and a few other bits and pieces. Couldn’t have asked for better service from the get go, Anthony was a pleasure to deal with, and the guys done neat professional work on the job itself, highly recommend
love coming to Newcastle pro sound. great install and great service, especially from Ziad & Anthony
These guys are absolutely amazing. I have dealt with them for many years. Michael has always fitted my systems, he is great & very friendly. They have done lots of radio and phone systems in my car and they have always provided wonderful, prompt & friendly service. I have just been there again today as my iPhone cradle broke (after many years) and Anthony fitted a vent magnet for my phone, he was an extremely friendly, happy guy. I will always be their customer while ever they are still operating. The floor staff are excellent and Hannah at the front...
Had new gear put in my Audi TTRS yesterday and when installing they came across a different electrical set up than usual. The installers and sales staff stayed back working late until 8pm on their own time without charging extra. The advice was good and quality of product is excellent. The first place I went for a quote gave me a feeling it was a load of crap to get me to buy the speakers that would give them the best margin and rip me off. So glad I went for a second opinion. Thanks Newcastle Pro Sound for going...
Great professional service, came in this afternoon for information about an installation, and the team stayed back this afternoon to get it done for me - extremely appreciative of their efforts and everything looks good and works great!
Great friendly staff, awesome service and reasonably priced product. I don't take my car anywhere else when it comes to audio electrical stuff.
Such a professional and courteous outfit! I was the typical high need customer armed with a bunch of unsubstantiated info from the internet.. Hannah knew an awesome amount about what I was looking for and when more info was needed, was honest and followed up on promises to get back to me in a time frame. Anthony understands what you need, knows his stuff and is great to deal with. Through the installation Anthony was a great help, inspected the install at handover with me, showed me how to use the tech! On top of that great support and aftercare....
