Hi, I produce bass-oriented dance music and am looking for build a sub that can decently represent bass down to ~10Hz in a fairly long room (2 or three small rooms in a row)... I understand this will have to be relatively powerful, but I am not very well versed in subs...

 

I am currently using two self-powered bookshelf speakers (Kanto YUMI) that I got cheap from a friend and they have a sub out... but I'm sure if they'll be able to power the type of sub I am looking for.

 

What are my options?

10hz is lower than almost anything you'll have in music, including dance music. If you want more SPL, you'll need to sacrifice extension. You might want to take a look at the gjallerhorn or just build a large ported box with a 15-20hz tune and some large drivers (18" and above).


It all depends on how loud you want to go. If you want extension down to 10hz, you're best just building a sealed box with a pair of 18s.

I simply need to be able to hear/feel the effect of super low frequencies at reasonable listening levels, they don't need to be particularly loud or clean.

 

If I were to build a box with 18's, what drivers would you suggest?

SI 18 or daytons are your budget drivers.

When you are looking to play really low, it comes down to your budget and how large you can accommodate. If you are looking for 10hz, you are going sealed. In this realm, it's a volume displacement game. You can do it with very long throw drivers or larger # of drivers. Get 4 to 8 18"s in large sealed boxes and you get 10hz thumping pretty good.

 

[notnyt]

I don't know where you grabbed 10hz from, but I doubt anything you're producing or listening to is using anything that low. You'd be pretty safe at 20hz covering all your low bass.

I just want to have all my basses covered.. haha

 

10 Hz does exist in some music and can be reached by large systems I have used.

 

I know it is rare, but I would like to have the option if it is possible for a non-ridiculous price.

dance music is only good loud.


big rooms like that have minimal room gain, so it is going to have to be mostly speaker.


low frequencies are more difficult to sense than high frequencies. this is shown in the equal loudness contour here:

http://en.wikipedia.org/wiki/Equal-loudness_contour


here is the response of two 18" driver configurations using the b&c 18ps76 (the kind of driver you might find in a decent p.a. cab).


one is 6 cubic feet tuned to 38hz. the other is 12 cubic feet tuned to 10hz.


now that is for 1 cab each. every time that you double cabs (and power), you get about +6db. so with the higher tuned cab, two cabs will give about 128db from about 38hz up. that is what you are used to hearing.


the other thing would require about 32 cabs to get the same spl level all the way down to 10hz. if that seems ridiculous, it is, which is of course why nobody tunes cabs that low for dance. a much better plan would be to tune the cabs for about 27hz or so. at least that way you have a shot at filling the largish room with dance level music.

I've been into the electronic scene for years and even ran one of the first internet radio stations which only played that. I've yet to encounter something with 10hz content. It's not something you come close to hearing, you can only feel it as pressure. No clubs or other venues have a sound system that will reproduce 10hz, because doing so gives up too much output potential and takes way too much power.


Again, just my $0.02. If you really want to go for 10hz, by all means, but for music it is silly.

Look man, I'm not gonna lie, I don't know my ass from a hole in the ground compared to some of the guys here. I do know this: budget friendly, 10 hz, and large room do not belong in the same sentence. The only thing I can even think of that comes remotely close (@ about 2 grand if I recall) is a single ported re xxx custom build tuned to 12 hz on data bass. You should probably re-evaluate your expectations.


Also, let's just say I ate some drugs a few times and I can't ever recall the bass extension of any rave I ever went to. I do remember some awesome d.j.'s though, and I will guarantee none of them came close to 10 hz.

+1. Getting to 10Hz requires a combination of a lot of speakers and a smallish room. You can find lots of speakers used in some pro setups, but the rooms they're used in aren't small. I recently did a consult at a new club that the owner outfitted with twelve horn loaded subs loaded with two LAB12 each. Called 'Therapy' in Providence RI, it instantly was proclaimed as having the best sound system in New England by the DJs working there. It's easily capable of 140dB at 25Hz in the middle of the room, but they hold it to around 120

.

Set up as the DJs like it maximum output is between 40 and 70Hz. Output at 20Hz is the same with the system off as it is with it on, 50-55dB, as that 20Hz content is traffic noise from the surrounding highways.

+4 I doubt 10hz is what you are really looking for. Its unremarkable except for certain movie and effect type stuff like pressurization otherwise its a largely wasted effort except for the ones chasing the 5%. I agree with Bill. If your intended use is as stated what you are looking for is concentrated above 30hz or higher. The bass that's really impressive that makes heart skip is like Bill suggests

Hi, I would gratefully appreciate a good tune that would occasionaly dip into the negative 20's.  Modern music lacks them low's. Equipment that people own is getting better, Hifi, Pc or car! Hip hop/ Rap from the likes of Young Jeezy or Lil Wayne is just single notes that they like to announce with phrases like, "watch you EFFING woofers, its going to drop!" or something like that! Boring! No, my system will have a go at playing 10hz, I got 2x15" in the ceiling on I.B. duty, 450 w rms at 4ohms, haven't measured yet, work in progress, but yeah, give us some CHOONES to 10hz please, OP please. Better than having to watch movies just to get things going low ;-)

 

Thanks

Mike

Here's how you do it.


1) Buy an old Honda CRX.

2) Park said old Honda CRX in your longish room, and maybe replace the driver's seat with a more comfortable listening chair.

3) Wall off the hatch/trunk area.

4) Put as big a woofer as you can fit on the walll.

5) Chase and fix rattles.

 

[jpmst3]

+1, +1 again.



Forget about the 10Hz content.


Even if it were in about 2% of the music you listen to, you have never heard it. It is simply not audible, if you did hear it, it was all distortion, hence the audibility.

Second, the human ear is much less sensitive to the lowest octaves. So, it takes a tremendous amount of resources to produce that at the levels you are expecting.

20Hz is below 95+ % of any musical content. The strong bass in the dance/rap, etc is more like in the 30-50 Hz range. Focus your efforts there and you will be a happy camper.


Cost effective and 10Hz/large room are antonyms.

Well... not really. Snag up as many SI 18HT's as possible and build clones of my LLT's.



Though the issue is this guy really doesn't want or need 10hz for what he is doing..... he needs skull crushing 40hz and up.

I guess it depends on what cost effective means as I have not seen a budget figure.

 

[allthetime]


What I meant by cost effective is what can produce desired results for the cheapest price possible.

 

I don't have a budget figure... the dream of 10 Hz has become more of a curiosity now after watching this thread play out. I was imagining massive upward and downward swoops in and out of audibility, transferring from something you hear into something you can only feel blasting cool air at you from a 100,000 watt system in the forest... slightly detuned unisons wobbling away, pushing people around. A niche, to say the least.

 

I suppose there's not much point trying to recreate it in a bedroom.

 

But I have learned quite a bit about bass and woofers from this thread and have a much better idea of what I need... thanks everyone!
