Cone Updates Part 1



As we transition to the upgraded HDS2.1 and HDS3.1 models we will also transition to green stitching on the HDC3 and HDC4 cones. We will start by rolling out the recones for the HDC3 15″ and 18″ cones. Once inventory for the 10″ and 12″ cones cycle through we will replenish with green stitched cones. This goes for every series including HDS2’s, HDS3’s and HDC4’s. In the coming months there will be more changes to the Heavy Duty Competition Series 18″ cones to improve stability. We will address these changes in Part 2.

As far as woofers, we will start updating the stitching on them as well. Currently the only woofer that will have green stitching within the next month is the HDC3.115-D1 so if you are needing silver stitching we urge you to purchase the woofers you need sooner than later if you are wanting to match them. We definitely understand change is hard and this transition may effect some of the bigger builds so please contact us with any concerns you may have. This change is to make SoundQubed a more uniform brand and comes at the recommendations of Qubers like yourself.

New Amplifier Line Up!

That’s right the rumors are true! We have discontinued the Q1-3500D.1! Don’t fear, we have replaced it with a bigger badder model that we aptly named the Q1-4500D.1. This amplifier utilizes the Q1-3500 casing and features the new SOUNDQUBED laser etched logo on the heat sink. The Q1-4500D.1 is on back order and are slated to be in mid April. If you would like to purchase one at the pre sale price you may do so HERE. Once the amps arrive the price will adjust to $839.00 shipped. The New Q1-4500D.1 does 4560W @14.4v at 1 Ohm. (1% THD)
We have also upgraded the Q1-2200D.1 to the new version the Q1-2200D.2. The Q1-2200D.2 has also been upgraded just like the Q1-3500D.1. We utilized the same casing and board structure while refreshing some internals to give us 130W more power. This means you could see roughly 2330W RMS @14.4v at 1 ohm! (1% THD)
The Q1-1200D.1 was also modified just as the two amps above. The Q1-1200.2 is the revised version and you will see 1310W RMS @14.4v at 1 ohm! (1% THD)

Here’s a preview of the amps at 10%THD…More Ratings to come!
