So! A lot of people are hyping up the bigger brother of the ks112...(the ks212c)....so I compared them both side by side, volume to volume, same song and everything at GC, but! Believe it or not the smaller Ks112 PUNCHED more! Standing about 5-6 ft away.....I was really curious and I looked at the spec sheets and the ks112 starts lower in frequency so i guess thats why you hear more knock?, But standing 30 feet away you could hear the 212more...so i guess the advantage of the 212 is just a difference in range? and not having sound in the back as much obviously (being cardioid)..but anyways thanks for the video above 🙏🏻💯
Have you noticed any feedback improvements on low frequency from your needles using real vinyl?
hi thanks for your video, one question why do you choose the 8 inch over the 12 inch top ? would you recomend that for dance music house etc ?
I love your enthusiasm!
I just checked and on QSC's website is states the sub has two 1,800 watt peak amplifiers built in, so that's 450 watts continuous average power per amp, 900 watts continuous average power per sub.
An oldie but a goodie
When you put the 2 subs together at the middle you get an Sound pressure level increase up to 6dB because the subs are in an ideal phase alignment, so every time you double the amount of sound sources, you get up to 6dB increase in SPL
In theory yes but measure the spl and you'll see it's maybe only 6db at most at certain frequencies.
thanks for showing some PA stuff, much appreciated, i like it:)
Hey Ellaskins. Random question: Are you in the UK? I used to watch RUclips videos about Pioneer CDJs and other professional audio video reviews and you remind me of that guy. If you are the ONE who used to do reviews and video recordings then you will know what I am talking about. Cheers. (do you still make contents?) - subbed.
Yes I am in the uk
You get more low frequency spl output from putting two subs together due to driver coupling, it's generally about 3db extra. You also get 3db extra output from a doubling of power so if you provide the sub with twice as much continuous average power theoretically you should get 6db extra. With regards to the QSC subs in this video I should think the built in amplifier's power is a burst rating. They built in amplifier are probably not capable of outputting 1,800 watts continuous average power, what the lamen called 'RMS power'. It's not actually called RMS though because RMS is actually a voltage term but manufacturers have been calling continuous average power 'RMS' for decades because it's easier for people to understand, although like I said it's an incorrect name for long term amplifier power. The correct term is 'continuous average power', look on QSC amplifier specs and you'll see exactly that term. Also to make it a little more confusing most power ratings on amplifers specs on websites and even in pdf data sheets you can download are in fact 1khz power ratings. This for subs is useless because subs aren't used up to that frequency. The power ratings to look for if a manfacturer lists it is the 20hz-20khz rating known as full bandwidth power. To make it even more confusing still you should look at what THD is on the specified power output. A lot of specs state 1%THD at a certain specified power output, that means the amplifier can output that rated power but with 1% total harmonic distortion. Any THD figure below 0.3% is good and QSC do a lot of amplifiers that at their rated continuous average power only have 0.1%THD at 8 ohms but at 4 ohms bridged or 2 ohms stereo it's 1%THD.
Also I might mention that the peak spl figures of any speaker or sub won't be accurate unless the peak spl has been measured using a Class 1 spl meter. Most peak spl specs are calculated and calculated peak spls specs never take into account the amount of power compression a driver suffers from. It's always safe to take off about 8-12db off a speaker or sub's peak spl specs to give you a more accurate idea of spl you might see on an spl meter. Although some drivers suffer from a horrendous amount of power compression so a speaker or sub's REAL peak spl output may be as much as 14db lower than the spec suggests.
I wonder what it looks like on the inside if you have never took one apart 😁
i hear great things about this sub> thanks
QSC products are very good from experience speaking to my local
Not really
Hi guys !
Thks for your review, Nice vidéo !
I have à évent agency,
Principal activity : Dj party
We own différent Sound systèm
Evolv50 / vertus2200 and k10.2 /12/8
I would buy a subwoofer to build a new system with qsc
Hésiting betwin kw181 and ks212
I know all thé caracteristic
Both are Good but with thé expérience
which One do u recommend me ?
Overall
Thks a lot
Anybody wonder how it would sound coupled with a 181 ... the 212c for tight bass an the 181 for deeper bass... hmmm I got a 181 already
I k they go well together as they cover different freq better, each has their optimal range based on cabinet so they compliment each other.
Did you get the 212s? Same here, have the 181s but would like to add some tight punch...
Hi guys I have 2 questions
1 - Can this sub (QSC KS212C) and 2x K12.2 Tops fit in the back of the saloon car (VW Passat).
2 - I have EV Evolve 50 speakers,can I use this sub (QSC KS212C) without any complications.
Thanks
so i have some weird vids of you in my video files idk how they git there but they seem old
Thanks for the info
20 000 kHz = 20 MHz :) just a misspelling :p ... 20 kHz ... however there is few energetic content till there ... the real top (with energy I mean) is within 13-15 kHz ;)
to be precise, it is not efficiency that you talk about, it is transient response. Just to make it clear :)
Nice shorts!
ezar howard 😂
It's not quite as black and white as you say Jonathan. I've heard unbelievable 18s that are fast and punchy and I've heard god awful 12s that I wouldn't give house room.
There's much more to this than 12s are boomy and 18s are slow but deep.
Definately, some 18" drivers are punchy as hell especially when put into horn loaded cabinets with a short horn path.
just a request: please edit your videos with a de-esser :p you have a damn sibiliant S :p
