The air space comment was so spot on. It's so annoying the myth that larger subs hit lower, it's stupid. Enclosure design is what yields lower response frequencies. So people wonder why stuffing 6 12s into their trunk doesn't sound as good as the 2 12s I have. In my trunk there's probably enough room for a box for 2 15s but it's cutting it close, yet everyone is DEAD SET on getting 2 15s in these cars, they just won't listen.

That was damn loud - I'd play a bit of a ballad and out-bass guys with 2x 15's playing EDM (Literally happened, at a packed car wash and it was pretty damn funny). Anyway, my point is, that I guess when we're young we want to be a bit showy - so we go for the kind of loud that rattles house windows of the girls we're interested in when we rock up but as some of us age, we realise that the quality aspect of loud makes loud EVEN BETTER.

He put 2 12s that need 3.5 cubic feet of air space in a 2.9 cubic foot (including port are and disblasment) box and hooked it up to a 750rms amp. Subs were 750 rms each. And ran a 4 gauge from front battery all the way back. I even got a brand new excelon kenwood deck 5v output. Spent thousands, and it sounded like my 250 rms 1 older shit sub.

Great video. I think one thing you should have considered with your adding another sub analogy was amplifier final impedance. If you add another sub and it's wired in parallel with the other one, given that amplifier can handle the final impedance of them both, it's likely pushing nearly twice the wattage, this is the case with a lot of amplifiers. I'm sure you realized this, but just figured I'd mention it, great stuff man!
@trev67833 жыл бұрын
I feel like you almost created a new myth with #2.. A 3dB increase, doubles the sound intensity, which is why adding a 2nd speaker typically gives you 3dB(sometime more). You need 10dB to double the perceived loudness. So you weren't lying, but at the same time there's a difference between sound intensity and loudness. You also need twice the power to gain 3dB, so after a certain power level, adding more speakers becomes more efficient than adding more power.

Back in the day (1991), my first stab at a ported enclosure was to modify a dual chamber sealed enclosure (heavily sanded Rustoleum gloss black!) into a ported one. It had my best friend's two vintage all black, steel framed, white dustcap logo, foam surround, Rockford Fosgate Punch 10's inside. About 1.1c.f. per side after the driver. I manually calculated a port size to tune it to 39Hertz and used an inexpensive program to verify. It was I think a 3 inch Schedule 40 white PVC tube cut to 9 or 10 inches. I used a round file and 80 grit sandpaper to carefully roundover and flare both ends. It was held in place with PL2000 construction adhesive/sealant. HOLY SHIT! What a HUGE difference! Louder with more punch and above 40 Hertz definitely less excursion and more power handling. MC Hammer and Snow were killing it (we were 8th graders in 1991). Any lower Q driver with an EBP in the ported range we were trying to port. Porting the 15's in the already undersized sealed enclosures was a huge mistake, and I told my friend this way ahead of time. We had to use dual 2 inch PVC ports and it was only 36Hertz. So much shuffing and poor control. Blah. Then we both heard and felt a brand new Kicker Solobaric 12 in a custom 4th order bandpass! Holy shit again! Now we were 4th bandpassing almost everything. This or sealed WITH proper volume and tuning. Two RF Series 1 gray coned, inverted cap ten's were destroying his bedroom and finally a 1989 Nissan 240SX hatch.

I've always been a "ported guy" but took verbal abuse from friends who swore by sealed for years. After decades of honing my box building skills and competing in sound quality with IASCA, people are surprised to see my subs are ported. My ears and my room full of SQ trophies tells me people are just regurgitating what they've heard. Now I'm not saying there isn't an advantage to sealed not having to deal with group delay (time it takes the rear wave to make its way through the port), but a DSP can compensate for that. Plus, the car is such a terrible listening environment that any minuscule advantage in SQ a sealed sub is supposed to have will never be heard. The benefits of deeper, louder bass with more output volume on the same amplifier are just too much to overlook with ported designs, IMO.

Great video, and I agree with it 95%.... But I have had two 15"s in my F150, in a perfectly tuned box, and they sounded great... and LOUD ! I then went to two 10"s also in a perfectly tuned box, and they also sound great and LOUD.... but not quite as loud, and they do sound noticeably better with rock or alternative. They just don't move as much air for techno bass music, or rap. Point being, the type of music you listen to most, can / should also have a bearing on what subs you should use.
@spill1t5 жыл бұрын
I disagree with you buddy. If all else is equal, e.g. box dimensions meant for subs and the correct amp power etc. then the last part of the puzzle is probably where you're finding your difference coming in - the tuning of the system. The dynamic range etc. of subs of varying sizes also accounts for something tangible. Mark's comment is therefore 100% accurate - it's not strictly speaking the size of the sub (for the music you listen to) that counts, it's about more than that.

@jedidiahcallaway37545 жыл бұрын
While it shouldn't be the sole deciding factor, sub size does affect sound quality. An 8 inch sub, having less mass and restriction, can move faster and provide better accuracy for fast bass (rock music) when compared to anything larger. The larger the speaker is, the easier it is to reproduce lower frequency. This comes at a trade off, worse transient response. Fast rock gets muddled by large subs, regardless of cabin size. An 8" sub will never hit as low as as a 15", regardless of cabin size.

(Btw, for $250, hot damn, they sound great, a pretty good deal) Anyway, I mostly listen to rap, and literally every one of my friends has said, “you need to port that box,” however, MTX designed those subs to work in a completely closed off enclosure. Like I said, whether or not it needs to be ported depends on how the subs are designed.

Adding acoustic fiber fill is intended to cause waveform scatter as the cone goes through its excursions. This will reduce parallel waveform reflections that can cause increases or decreases in loudness at specific frequencies, based on the tuning size of your enclosure.

Myth-ish. Proper deadening/batting/box construction can make a small volume box sound better than a poorly made larger volume box, but not really make up for the lost airspace. If you were to swap out the oversized sub with one designed for the smaller, deadened box you would still get an additional improvement in sound quality ( if the speakers were otherwise the same).

with the same amp , yes. It adds 6db if driven by a second amp of equal power to the first. Every doubling of power adds 3 db and every adding of a same sized sub adds 3 db, so 6db total. I don't think he explained why it went to 6. So upping your amp output from 100w to 200w will add 3 db of SPL. Going from 200w to 400w will add 3 more. going from 400 to 800 will add 3 more. So going from 100w to 800w will add 9db if using the same sub. Easiest way to add DB, buy a really efficient sub to begin with. Don't buy the cheap 85db efficient sub, buy the much better ( and costs more ) 88db sub for $50 more and you gain 3 db just in sub performance. Back when I competed in the late 80's, pro subs were 94-98db efficient. We could get 120db from 200w amps. ( Amps were much more expensive and all were class a/b amps ) Now it takes 300w to 800w to get the same thing. Class D amps are cheaper so Subs have gotten less efficient.
@BoboButYouCanCallMeTom4 жыл бұрын
When the subwoofers are stacked (coupled) or very close to each other it can add up to 6 DB this trick is used a lot in PA systems. Since low frequencies are omni directional any way you don’t necessarily need a stereo subwoofer setup. Because its going to be quite hard to hear where the sound is coming from anyway. Also in most mixes the kick drum and the bass guitar are panned dead center so there is no need for stereo anyhow. So thats why they are stacked, rather have the extra DB’s then have a stereo system that will likely not be used anyway.

Back in the late 80's when I competed, I built a few really great sounding systems with nothing larger than 8" subs. I ran an Orion 225HCCA driving 2 pairs of MBQuart 6.5" and tweeter separates and the Autotek 7050BTS driving a pair of Lanzar Pro sealed 10" subs in the 100w and under level. All in a mini truck.

But it will work great as an actual subwoofer. from about 60-70 hz and down.

Well, in a very simple sense, more come area equals more base. (I’m aware that that’s not the exact reason why, however, it is generally true) The larger the sub, the more cone area. However, it also just depends on quality. I have a relatively expensive set of 2 MTX 12” subs in my car, they sound good, hit hard and fast, and are amazing value for what they cost. However, my dad has 2 10” subs in his car that are wayyyyyy louder and produce ridiculous amounts more bass, can’t remember the brand but they’re some sort of badass made for competition subs. However, in the majority of cases, bigger subs do actually mean more bass.

Rite now i have 2 atrend bbox truck boxes at .80 ft³ per box minus the .10ft³ for displacement of each sub so .70ft³ per box per sub rite now on a alpine mrp 4501.d, and it sounds better than i ever thought. Now i bought a skar skv2 1500.1D amplifier and i think im going to need new boxes or a new single box with the added power. What are you thoughts and recommendations. Sealed, ported. I like crisp clean sq notes where you can hear every note in the song no matter the frequency. The subs handle 500wrms and 800wmax each. How would i go about building a box that will still leave me plenty of leg room and comfort for snowplowing long hours in a small single cab f250. Any thoughts would be awesome, or a place who can build one at a affordable price, or a good prefabed box that will be 1.10ft³ per sub, hit every note with authority, leave my truck totally work friendly, and be able to handle all the power.

Yes, you should of course consider the space you have, and the power you have. But still, two equally powerful and same quality subs, one a 12 and one an 18, will not sound the same. In many cases, the 12 is a great size because it does work better at higher frequencies, but it will still play low, but also fast. It is what it is, but the size has zero to do with music, and all to do with what you want to do with it.

Phillips 4inch in the front doors, Tweeters higher on front door panels, The two redline subs in the rear seat along with two 6 by 9 Boston Acustics in the rear up top. That system had great sound and power. It was well balanced and so clear. I am looking to try and recreate what i had in my Mercedes S550. Oh did i mention the deck was an Alpine CD Player. and there was a denon amp for the 6 by 9's and a mobile amp for the subs. A large crossover and two smaller ones for the front along with a small amp. Later my installer suggested adding bigger mid ranges in the front doors. So we upgraded the 4 inch phillips to 5 and a quarter SAS's. And we also added two same midranges in the rear on the sides just under the window toward rear. We replaced the redlines with different subs that were bigger on the back side, However this upgrade to me did not sound better. The subs were more booming sounding which wasnt as punchy and the 8 inch redlines.and the mids were too much.

Providing you with more wattage to split between. But I get it your just explaining the basic misconceptions.

Definitely agree to all of these, and I'm not even an audio expert. I DO understand the whole "rock, do small, rap go big, only in that in basic levels, it seems bigger has slightly slower response, and also bigger cones move more air, and can thus create powerful booms of bass easier, tho I've heard plenty of great 8" and 10" setups. The same could be said for sealed and ported boxes. Ported generally being louder but slower response due to no air pressure dampening like a sealed box, where the air inside acts as a spring to help control the cone and create tighter reproduction, which is great for the fast double bass drumming of rock and metal.
@TH3_T3RM1N4T0R7 ай бұрын
I know this is an old post, but: A properly designed ported enclosure does not have a slower response than a sealed enclosure. That is a myth. Actually the converse can be true if well designed, since a properly tuned port allows the diaphragm to respond faster to the signal, with variable suspension that is tight where control is needed, and more compliant when required. Not all ported enclosures are properly designed, in fact most commercial ones are designed to keep costs down since it is cheaper and easier to get an underwhelming driver to perform adequately, than it is to fit a decent driver in a sealed enclosure and get good low end extension. And not all of them are designed with linear frequency response in mind. Some are actually designed to maximise gain around a certain frequency, and this is a calculated move to match cabin/room gain - in competitive cases it isn't poorly designed, it's just a one note wonder/burp box designed for maximum SPL. Remember that the port contains a specific amount of air, and that air has mass, that's exactly why it is possible to tune a port in terms of cross-sectional area, and length to get a desired resonance. Typically for the purpose of extending the bass shelf - and although it has a sharper roll-off than sealed enclosures, the F3 can be adjusted to be a fair bit lower down the frequency scale than anything you could achieve with a sealed enclosure. I have yet to see a 12 inch sealed sub hit 18Hz with any authority whatsoever. They are mostly underwhelming, even when you throw 2 KW at them. It just isn't feasible. That air in the port also acts as a spring, and around the tuning frequency it works in conjunction with the the internal volume of the the enclosure in terms of dampening - which is the opposite of loose and slow bass - which makes your point slight bit of misinformation. What does happen, is because of how bass works, lower frequencies have longer wavelengths, so ported enclosures are technically slower (in terms of Hz) and because of the reinforcement granted by the port (which acts like a passive radiator at those frequencies) the bass has a much more audible decay since it hits harder. And because it can hit those lows with so much authority, room interaction is more prevalent - which, due to the wavelengths concerned (18Hz being nearly 20 meters), creates unintentional group delays and standing waves. This is what you perceive as "slow bass". And if your sealed sub could hit those lows with the same authority, you'd have the exact same phenomenon occurring. This is why multi-sub setups are so popular in Home Theatre applications, having more drivers placed equidistant from the listening position, eliminates the need to over-drive a single sub to reach all listeners without creating detrimental room interactions or reinforcing unwanted peaks, only when done right.
