Want Subwoofer Performance? You MUST understand Hoffman's Iron Law

Автокөліктер мен көлік құралдары

Many of you are likely familiar with the "Iron Law" for performance cars: Fast, Reliable, Cheap... You can only have two. A similar law applies to the design of speakers and enclosures, and since I know how much you all love subwoofers, in this video we will be discussing how to get the best subwoofer performance, using "Hoffman's Iron Law". You see we have three items: Box Size (Compactness being ideal), Speaker Efficiency (Sensitivity), and Low End Extension. You only get to pick two! Let's discuss!

    Subwoofers that manages to put SPL and SQ in the same sentence for a reasonable price are my favorite like Skar Audio and B2 audio for example. JL 12W7s, Rockford Fosgate T2 13, or Focal SUB12WM are nice and all but, will completely crush my sound system budget and not be able to afford the stuff that is needed to make the subwoofer work let alone adding in speakers and a 4 channel amp to complement the subwoofer on top of that. However I don’t mind spending up to 1500 dollars on a very nice system that is has better sound quality than Bose and also louder than any stock sound system with DIY installation. I’m not so crazy with SPL but as long as the midbass, mids, and highs are around 110dB and sub bass is around 128 decibels, I am happy. I desire sparkling crisp highs, clean forward mids, and tight punchy bass. I like sealed enclosure because they block any mechanical noise and the bass notes in hi tech Psytrance sounds separated instead of smeared together.

I don't really care about SPL therefore the sweet spot for my setup is about 95-105 db. It can easily reach 129 db but looses SQ at that level.

    I remember back in the 80s. Rich kids would drop a thousand dollars in their car stereo and get pissed when I blew them away. All I had was a 100W amp and 4 15W home speakers in the back seat. My secret - those home speakers were rated 101Db sensitivity, and I cut out all the bass below 50Hz, so I would not blow them. These rich kids were buying expensive subs that got great low end extension at the expense of SPL. Then they would get pissed that my cheap system designed for SPL is so much louder than theirs. Even better was that I could pull speakers out of the back seat and put them on the ground or roof and we would have good sound while at the swimming hole, or outdoor party - all the mids and treble was not confined to the cars interior. And since there were 4 of them, I could point 2 in one direction, 2 in another and cover a huge area. Peeps liked it. Back then, we had these FM boosters that actually worked - and lasted years. Every FM booster I see today are designed like shit, don't work, or can't survive more than a year or two in a car. It's why most people don't even bother with them anymore. I still get a kick out of systems that have high pass filters on their subs. That's the wrong place for it. Such filtering should be placed before the amplifier, not after. Putting a filter after the amp is just making the amp do work you don't even want. All your equalization should happen before amplification. Even some crossovers should be before amplification if you have a separate amp for subs.

The air space for the 10's are dead on, about 1.22cuft per sub, but the 8 inch box has about 1cuft of space per chamber and the 8 inch w3 JL recommends .35cuft per sub. What would you recommend?

    My sub stage is a Stereo Integrity hstmk12ll, it is in a 15 inch baltic birch double walled cube, yielding around 1cuft sealed, powered by am Incriminator Audio 3rd gen IA20.1 at 1ohm. The efficiency for the sub is rather low, 83.7, but I must say that all that have heard my system are not only amazed that there is just one sub, but how tiny the enclosure is as well. I had a very reputable builder/installer tell me that he would not put my sub in a box that small, even after I showed him that the builder of the sub stated the proper size box for the sub. The specs for the sub call for a .6cuft sealed enclosure, and mine is about .55cuft after displacement. I plan on paying him a visit, so that he may hear what it sounds like in such a, I will use his wording here; tiny enclosure.

    I'm in the midst of first speaker project. I watched countless hours of video, read, and got lost in the sauce. Then I discovered the manufacturer graphs and recommended box alignment for ported or sealed. Then I discovered a rule of thumb formula to determine ported or sealed. I used the graphs to select crossover. Maybe if I make more I will buy a microphone and all that. But for now I'm going with manufacturer data. I found this on your sub manufacturer website:. Our HST series are designed for massive amounts of bass out of very small enclosures.

    When you spoke about optimisation and trade-off I was thinking about my old, pre 2000 Fiat Panda I drove. Which has a sort of a hammock where otherwise the dashboard would be. You'll have to Google the interior pictures. Because of the hammock the speakers where facing your ears (you could buy cheap speakers with enclosures that fitted right in to that hammock). After I changed those speakers for some second hand Focal 3" speakers, which have a high sensitivity. Powered by just the car radio (Pioneer). And installed an under-seat woofer. I seriously had an expierence like listening to my dad or brothers old home stereo systems as an kid. That I forgat all about through the years of computerspeakers and all that. Found my love for that sound again in that little car. Got another car. Speakers have to be in the doors and in the dashboard, facing upwards to the front window. Bought an 6,5 compo set, same brand. An proper amp (mxr rt60). Properly wired. Same under-seat woofer. Still nowhere near the sound I had in that little car. (Though admittedly I still should make a proper fix for my tweeters. Some day. As well as some door treatment.) The small size of the car itself, small speakers facing the right way made for a real nice, full sound. Balanced, rich, phat. Even though it was just a small, silly car with a relatively cheap sound system. Could have been any brand btw. Made a list than of speakers I was interested in and these where simply the first I found for sale. The guy who bought them said they had to much depth for his doors. Because of the hammock I had no such problem. (The guy owning this channel wouldn't have any problem fixing any speaker to any door btw ;). But anyway the speakers didn't let down. Which I doubt any of those brands I thought off would have. Just to say I don't want to promote anything. Besides good speakers in general that is! :) Nice channel. And thanks. Been watching on and off for years already. Take care.. Sorry for typos and weird grammar.

    I got a sub question. I got a 2013 impala and I'm thinking about putting a sub in the rear deck. My question is can I just mount a sub there and not have a box, aside from the trunk itself? What kind for that application? A free air/infinite baffle? Or should I build a box on the. Underside of the deck. I'm thinking if I do that I can get a shallow mount maybe. I want it to perform but don't want to give up a ton of space either. Thank you

    Back when I was first married ('87) and still had no money... I once had a 100 wt/ch (30 clean) and two 8" woofers I adapted to 4x10 holes and a sealed back mid and tweeter sitting up aimed forward, and made custom x-over, oh, I paralleled with separate xover the front speakers (so I had no F&R control) as all but the woofers were 8ohm so I had 3.5" full range with high pass filter for the front. All were rated 96db/m/w or more and I could get 113 dB in the car... plenty loud and super clean... all for about $200-250. really good bass, clean highs and clear mids... Then folks wanted me to help them.

    I'm glad I watched this video. I have a new 2021 Ford Bronco getting built next month, and I chose the high package which means I'll be getting the standard 6 speaker setup. I'll be getting (4) 4 1/2 Inch speakers 2 front / 2 rear with (2) 6-Inch Mids in the Front Kick panels. I knew I would be replacing all (6) speakers with upgraded components as soon as I pick up the vehicle. But, I also wanted to add a Subwoofer. However, I wanted to add the Subwoofer in the Rear Side panel, just like it would be had I chose the Lux package. Since that's a relatively small enclosure, I would guess I'd go with Compactness and Efficiency, since crystal clear sound / mid-level bass is the most important for my setup.

My question is, would it sound better with the subs firing toward the cock pit, or facing the back of the trunk? or does it even matter? The box will be made of the typical 3/4 thick MFD panel.

    I had a question regarding subwoofer and its amp, does it matter a SQ sub is paired with a normal amp as long as the rms power and impedance is matched or a normal sub paired with a sq amp or should it be both sq for better sq? Also in a sealed enclosure for SQ, if the manufacturer recommendations are considered for the box size, does it have any impact adding polyfill/dampening, if yes how much should be added or is this only good for SPL?

  • @zososldier

    @zososldier

    5 жыл бұрын

    It depends on you budget. If you are getting started or on a tight budget and you want SQ, a decent brand amp that meets all needs plus a well tuned box should suffice. Putting polyfill does more than "make it louder". It also helps cut down on box resonance (Think "ringing" of the box. kind of like when you knock on something hollow vs something solid).

    no mate the 4 channel amps are not bass amps get you a Mono block at a proper shop the difference is one can take the punch and only play low notes the others can't and will burn out if it's playing a subwoofer that and a few other reasons is why your amps running warm buy two monoblocks fit to the subwoofers RMS rating and the 4 channel amplifiers with a crossover for the door speakers also upgrade your battery and alternator just for incase get the correct wiring etc. watch more vids about these topics here on marks channel

But it's efficiency is 83.7hertz, and it is ran on a incriminator audio ia20.1 at 1ohm. So it goes along with what you stated in this video, less efficient, but more power to be able to utilize the compact enclosure. It is articulate, deep, and what a friend of mine calls; substantial bass. The hst12mkll is designed to be run in .6cuft sealed.
