    Just ordered two HDS3 10’s. Packaging was top notch, and voice coils measured spot on at 4 ohms each upon arrival.

    I’m building a box for two, but I’m breaking one in, in my current single 10″ box. They sound great! Nice warm tone, with fantastic impact! Only giving it 800 watts now, but the pair will be fed by my Orion XTR2500.1dz. I would have loved to get a SQ 2500 amp, but I have a 12 passenger van and can only mount the amps under the seats…. the Orion was the only good amp with a smaller footprint.

    I’m very impressed with this HDS3, and cant wait to run both of them. My kids (5 of them, hence the van LOL) love it already 🙂

    I bought this sub on Nov. 23, 2014. I left a review after I installed it just prior to the break-in period.
    It has been almost 4 years since the install and so far I have absolutely nothing negative to say regarding the performance of this sub. I still am using a Planet Audio AC3000.1D mono amp at 1 ohm stable. The RMS power output is 2100 watts. This sub is freaking awesome. It has not skipped a beat since I installed it, no matter what I have thrown at it. This thing is a first-class performer. If you are considering buying a sound qubed sub, GO FOR IT. You will not regret it.

    After speaking with sales and tech I was encouraged to purchase the HDS3 15’s even tho I planed on purchasing the HDC line they informed me and did NOT oversell me subs I did not need due to my amplifier and intended use they flat out saved me 1/2 the amount I spent.
    I was unhappy with the subs I had(vvx v3 15s) and replaced them with the HDS3s and I must say from this day forward SoundQubed has a customer for life, the sub is far superior to anything else in its price range and takes a beating.
    I have my HDS3s in a 6/18cuft 6th order bp on a kicker kx2500 @ 2 ohm, everyone who sits in the “ whatthefuckus” ( focus wagon ) is quick to gtfo, she gets it done for a very affordable system.
    If you need a quality sub that’s affordable HDS3 is a great option.

    I just ordered mine on Friday! So I heard the same one I bought on the 1200 with a2.7 cube box tuned to 30 hz and all I can say is holy sh*t! This thing sounds clean and low and for the price ,should be 4 times the price! I usually don’t do reviews but I’m almost done with the trunk with tons of dynamat cause I’m gonna need it! Best sub I’ve heard in awhile hands down,I also got the s1250 for the 1 sub

    Got me a brand new hds3.1 15d2 today. Had a used one but was pretty toast by the time I got it. These things are impressive for the price. I’m going to order another new one soon. And get old one rebuilt as a spare. Love sq.

    Just uninstalled a HDS3.1 15 D2 in my 2008 Ram Single Cab in a 3.8 cube box after port and woofer displacement tuned to 33 Hz on a skar RP 2000.1 and this thing rips it’s so much cleaner than my 2 skar DDX 10s and seems to be handling the RP 2000 couldn’t be happier SQ FTW

    Loud, yes. worth the money? Yes. Play low? Not as low as my sundown SA 12’s Gets Stinky at about half tilt on a Soundstream ta1.3000d wired at 1 ohm with gains less than half. Overall good sub for the money, just wish the beast played strong lows like the 2.5″ coiled SA 12 on the same amp & resistance.
