@xdrm24 Agreed! I bought a rockville marine 8 channel marine amp with built in blue tooth, it sounds great with 6.5 and 6x9. However if you use the Bluetooth every time you power up it plays at max volume starting, wtf? And I blew every channel I hooked the sub to. Really weird. Rockville is cool because of the massive range of products but sad it couldn't hold up. I ended up buying a cadence bluetooth controller and now wish I'd just went with a skar without the Bluetooth in the first place. It's cool you live and learn.

I bought a 12in powered spare tire mounted sub for my car, and it really does well for it's cheap price and power level. It shakes the car and sounds decent enough. These units mount right inside the spare tire itself! I like the looks Rockville's compact truck under-seat mount subs too, and have been considering one for my dad's truck. Would I use Rockville for a higher end setup that I cared a bout? Nope. Am I really enjoying it for the cheap price, decent sound quality, and stealth zero space mounting options of the spare tire mounted subs? Absolutely!

These are fun and cheap content for you to create, I've never stopped looking at and wondering about all the

[@2011joser]

I am puzzled by the use of a class a/b amp in this sub. Unlike the JBL and others, this is clearly a well thought out design not aimed at the lowest cost. There were investments in the castings for the enclosure, the physical layout of the amp board, and the passive radiator vs a port. Are the components for a class a/b so much cheaper that its worth using them even in a custom amplifier like the one in this unit? Thanks for keeping it interesting Big D.

[@wal]

The cheap A/B amps are like $10 cost. Like I said we usually praise AB amps for SQ but the cheapo ones are an exception

[@wesw9586]

Just Cockville getting whatever they can for cheap to sell a product. That's what they do.

[@CL-yp1bs]

The super cheap designs its cheaper to use class A/B its just the chinese factory using old leftover obsolete parts.

[@AraceaeFanatics]

Being Rockville, it's probably something from a Chinese factory catalog that's marketed differently elsewhere. Rockville doesn't design or engineer anything, it's all off the shelf ready for a name to be slapped on it. With the advancements in technology of amplifiers in the past 20 years, they could have easily opted for a class D amplifier and actually had their first successful product. This is still decent for so many, and it will definitely work for its target market, but it could have been better.

[@303nitzubishi4]

Yeah I was thinking the same thing there was obviously some investment in engineering the passive and active drivers with the cabinet and then they take a custom circuit board and put crap components on it to power the active driver. For the crowd this type of product is aimed at I would guess they would be willing to pay a few more bucks for a legit 200 watts from a class D amp instead of this joker setup

[@Joshtheweatherman]

Rockville is pretty underrated. I’ve owned a few of their subs, and they’ve always put a smile on my face! My current setup is a single Rockville Destroyer 15D1, mated with a Krypton M5 mono amp. Best bang for the buck subwoofer and amp, with very impressive lows inverted inside a ported box. It was going to cost me around $300 more for a similar Skar setup, and way more for bigger brands.

[@jeff0561]

Great review and testing. I bought this when it first came out due to its size and thought it was pretty good performance for size and price. Thanks for taking it apart to show the inside.

I just got this thing installed in my Volvo xc90 and once I got it all set properly it sounds amazing. Very happy with it. I would recommend this sub to anyone.

[@endall39]

Interesting vid! One thing that occurs to me is that you could play with the tuning frequency by changing the weight on the passive radiator. Could possibly get more low frequency output

[@russellzauner]

too bad I can't tune the mass while stimulus is being applied...

[@91CavGT5]

With how small the enclosure is, it would be interesting to see if any low end improvements could be had at all.

[@BabyCharlotteschannel]

@@91CavGT5 for sure, I love seeing how much improvement, or loss, of sound happens when "tuning" ..

[@cpufrost]

@@russellzauner You can, you just have to use a real woofer and use another amp to provide a load. ;-) The easiest way to lower the tuning frequency is to epoxy fender washers to the middle of the PR. Of course the box is pretty tiny, probably not going to matter much.

[@PoXFreak]

When using something this small, I'm not one to tune for max db, I shoot for a flat response to at least 35hz. In lieu of tuning the enclosure or PR in this case, adding power where the extension rolls off can be a blessing and a curse because, with each 3db rise in output, you have to double the output power delivered. I can't see this thing handling the power needed for it to create 120db at 35hz, not for long anyway.

[@1toonhead]

Passive radiators are a interesting way of getting bass. To get the lower bass notes you need to put weights on the cone to lower but it does take away the upper bass. Its all about balance. Also a way of telling when the phase run out is run a hertz cycle, when the two drivers are working together the passive has done its job. When a passive is working, the woofer would look as if its not working and the passive is going hard. I've built a home theater system with passives and I can get 20 htz out of a single box. Does need at least 2 subs to make up for the loss from the woofers. Does sound super clear and true.

This sub reminds me of the original Infinity Basslink from the late 2000s. The Basslink was pretty impressive for what it was. It too had a 10" woofer and passive radiator, but it had a composite enclosure and a "200 watt" class D amplifier. It would be a great product to do a video on if you can find one. I had one for while and was pretty impressed with it's output considering it's relatively small form factor. There was nothing else like it at the time.

Very interesting. I heard that most amps that Rockville makes are up to the spec in terms of wattage, and Rockville claims that they are CEA rated. I bought a Rockville DB11 sub amp a year ago for my 5.1 sound system because it was very cheap at that time and has a lot of watts. I'm using a 750W HP server power supply to power it indoors. The amp comes with a dyno sheet in the box that says 233 watts RMS at 4 Ohm and 1% THD+N and 391 watts RMS at 2 Ohm and 1% THD+N. Hopefully the dyno sheet is genuine and it does what it claims. It is able to flex a kicker CompR 8 inch sub hard at high volume and is able to make a cheap sub's coil smelly (and possibly blows it if I turn up the volume higher).

Great content big D I been wishing for more "real world" tests on this type of equipment and you've given me a great Christmas gift thank you!! I would never consider buying a product like this but I do appreciate the engineering that was put into the casting of the drivers integral with the cabinet. I think that's cool I wonder if it's a knocked off design from a legit brand? A bit more airspace and a class D amp with double the RMS output and they'd have a winner here! I'd bet folks would have even been willing to pay a few bucks more for a product that gets approval from influencers like you. Manufacturures will eventually wise up and improve on products like this based on reviews from folks like you and the feedback here in the comments. Bass onnn my friend

Love that D4S jp8. Cant wait until I get it with that awesome remote knob. These amps remind me of the US AMPS. I was at the 93 IASCA Finals in Tulsa and US AMPS were demonstrating that they could light pencils on fire and cut soda pop cans in half. Rating that these amps could run at a "dead short". Impressive. Yeah boi👍 The sub here is an entry level on a budget speaker, plain and simple.

[@johnbcardin]

Some feedback: I like the tests and the multi faceted approach to this. I found that the tests for the spl levels seemed to drag on a little. I would suggest pulling the “bass incoming” delays each time. I would also like to see a sweep to find the resonant frequency and then a spl bump that that frequency. Maybe two more bumps at 32hz and 55 hz. Three tests at a max for spl per set up. I did like the external amp. That was cool. Overall this was great content and a great addition to your standard formula.

[@wal]

Thanks for watching and commenting!

[@mysock351C]

To really do this properly requires some form of RTA. If you look at the snapshot of each of the sine tones its clear that the sub is progressively distorting more and more below about 50 Hz from the wave no longer being sinusoidal. Further the microphones in the smartphone are not accurate and are significant sources of error in their own right. Finding anything meaningfully accurate about the tuning will be quite difficult. Personally I think sticking with what Dereck currently does but with maybe some more streamlining quite acceptable given the limitations of the current test and the audience mainly being concerned with SPL output. Trying to extract more information without going to a dedicated setup for measuring SPLs with some form of calibrated microphone and instrumentation isn't going to be very meaningful due to how much error there can be. Yeah we could invest in an inexpensive measurement microphone and go to something like REW or a similar package but that might complicate things beyond what they need to be.

[@mysock351C]

And this doesn't even include the consideration that the SPLs here are likely due to the fact that the amplifier is probably close to flat-topping and this means it can generate substantially higher SPLs than it could if we had a 1% THD limit for its power output when determining SPLs. Run like this its basically a class-D amplifier that only plays square-waves. It will be quite loud, but with distortion in place of the music. The test would need to take this into account so we don't measure the wrong thing.

[@XX-121]

dude, most of us want it to sound good at all frequencies, not just the only one the speaker can handle. why do you think these rip off artists test at 1khz?!

[@mysock351C]

@@XX-121 Most internal sub amps are not designed to play at 1 kHz. There's no reason to make it full range, and extending its bandwidth needlessly just creates more problems and solves none since its not needed. Technically this is a class-AB so it may be able to play full-range depending on how its set up, but any real measurements (THD, noise, etc.) would not extend past 250 Hz.

[@johndoe-vb9sm]

Thanks for that. Interesting. I spend a descent amount on my Car and home audio...and sometimes the cheap stuff is better. I say that because of deminishing returns on your money has a stopping point. Twice the money but 5% better sound and or less noise or whatever your subjective ears are hearing. Case in point for a few instances Ive had. Bought a Sennheiser Ambeo soundbar which has tons of bass for standalone bar and super $$$.Then I bought a cheap Elac 10 sub for $130. Then tried a Polk 10 sub $350. Guess what? Took the Polk back. Elac has just as much bass as Polk, smaller, hits super low,but more tjan 3x price. Only down side to Elac is gain noise which can be tuned out almost all the way or I just unplug it when its not used. Great vid👍

It would probably sound better if the passive was tuned lower. (More weight) looks like that 93hz was a third order tone and there was a strong 62hz 2nd order tone too. It would be great to do a test with the passive tuned lower, to see it hit low. I bet it would. 😮

You should get a Dayton WT3 for when you test these woofers. Then we will know if they are in the appropriate box. Based off the curve, I see a high qts driver in too small of a box. Add another ft3 and then see what it does 👌

Thanks for the suggestion

Would take a lot of work and destroy the cabinet on this as the baskets are cast as part of the box.

[@Ellington_Industrial_Arts]

I was thinking the same thing...test the sub in an optimum enclosure. Then I read some of the other comments and realized that the sub and radiator baskets, are cast into the encloser. Which, is a super weird manufacturing decision. 😒

How about some tests of head units? They're rated at 200w (50w × 4 channels), but that's ~16a @ 12.5v, and since cars have frequently had 10 - 15a fuses for the radio… That can't be right!

[@wal]

Most heat units are 14w/ch as they use the same amp chip with the exception of some older Alpine and Pioneer and also Sony has a more powerful model that’s a true 50x4

[@Mr.Robert1]

Every head unit that I purchased including pioneer, Alpine, Kenwood, JVC. I never used the internal amplifiers to drive anything. That's just me, 99% of the time I used a two amplifier system. One monoblock driving either one or two subwoofers. Followed by a good quality 4 channel amplifier running my mids and highs. I've done many installs over the years. This is the way I do it, to each his own.

[@Iowa599]

I'm using only a head unit to save weight, and while most are the same, it would be nice to know which aren't, & the real numbers.

Sony had a head unit that I used back in the 90’s. It had line level outputs like most decks, but it also had line level inputs!! I had the outputs running to a Sony electronic 10 channel crossover, then going back into the deck. The front speaker outputs powered the tweeters and the rear channels powered the mids in a set of 6 1/2” Cerwin Vega components. Then I had the subwoofer output on the Sony crossover going to a Sony XM-2025 that was bridged on a single 8” Lanzar sub in a sealed enclosure behind my center console on my car. For sound quality it was actually really good and with no equalization it scored a 13 out of 20 on the RTA. There were some truly revolutionary technology that was in car decks in the 90’s!

Really curious to see how the rockford fosgate p-series powered subs perform

[@Mr.Robert1]

Passive radiators are much better than ports. I'm surprised they're not used nowadays. I remember seeing them many years ago when I used to fiddle around repairing home speakers. They make a big difference in low end that's probably why this unit sounds better than the JBL. Big D does a fantastic job in what he does. I enjoy every video he makes there is a downside. Every single time Big D does a test on anything the price immediately goes up. As soon as this video was put on KZbin Amazon raise the price by $20. I'm sure in a month from now they'll be selling it for close to $200.

The RockvilleAudio site had it for $129 www.rockvilleaudio.com/ground-pounder/?from_autocomplete=Ground+p-42092

[@Ale11Re]

I love all of your testings! Could you rate a pioneer TSWX300A powered subwoofer? It's around 150$ I think. Keep up the good work!

[@MrBarkley76]

Nice! Plug and play subwoofers don't get enough credit

[@scottborst5430]

That’s pretty cool thank you for doing this detail work on this speaker plus amp in a box kit. Have you mess with any of the DS 18 stuff yet?

[@vannloc7551]

Big D. You should try out one of the skar bass tubes. I bought the 8-inch one N although it wasn't as loud as a custom box it wasn't too shabby.

[@wal]

Thanks for the suggestion

[@viperfanatic13]

I would love to see you review the Rockford Fosgate P300-12 Punch all in one system.

[@Adam-nv9zo]

Merry Christmas everyone !!!

[@frickandfrack841]

What powered subwoofer do you that is the best worth the money and loud

[@StaticVapour590]

At least it got creative name, kinda looks like it's from those "home theater in a box" sets. At that price it's quite funny how it's assembled from two large pieces of metal and not from plastic... That amplifier inside is probably some leftover chinese warehouse junk

[@resistor888omega]

Sir, what app was being used in the spl test?

[@HeyItsJonny]

I bet that isobaric radiator in a metal enclosure sounds pretty unique. I'd have to hear it in person to know if it was a "good" sound signature.

[@daveme3582]

Im with Big D. For the $ I was impressed. Cast basket sub and radiator into the metal enclosure for $130!?! One look at that stock class AB amp and I was all, thats not class D???? AIO cheap subs its often the amp that gets the biggest cost cutting. Good on you D for doing a test with a decent amp on what was given. These types of tests are fascinating to me. I wish uber budget minded teens would discover stuff like this and do it in real life. Id happily buy this sub, mod it, add a decent cheap amp and be done on a budget. Heck $200 total sub and cheap amp and have an acceptable thump in my trunk. Who can argue with that!?! Bananas how cheap and good things are compared to what decent cost in the 90s right?

[@wal]

Although not a great sub, I did all I could to see if the amp was the limitation. Fun video but took a while to create

[@familyman8644]

Do you think alpine type R 10 with ported halo box paired with M-S60 alpine 750 watt rms amp is louder? Im thinking those phone apps might be little off. Im only getting about 120 db when phone is near woofer flexing over an inch excursion. Im getting about the same db level in the cabin of 97 Lexus es300 with ski hatch open
