Small SubWoofer, Low Frequencies

Do they exist? I don't want a huge woofer, but one that right down low.
I have a medium sized room and two Mackie HR824's and I'm sorta craving the frequencies that aren't provided by them (39Hz and below)

I'd consider spending up to 500 GBP

got any ideas?

I don't think (m)any systems go below 40Hz tbh.... :o

what? yeah they do. 20hz isn't that uncommon in monitoring subs. Sure a lot of speakers roll off about 30 or so but they'll still respond pretty well past that. Some even respond accurately all the way down to 16hz

Very much doubt it. To get a good level of response down to those frequencies at high levels you need to move a lot of air so big cones are a must. Dance music doesn't tend to go that low as it uses so much power. More of a problem if your into Organ music (which is the only traditional instrument that goes down to 16hz).

Go for the 12 inch mackie sub :-D It starts to roll off at 12hz if I remember correctly.

Your neighbours will be shitting thier beds

If you mean the Mackie HRS120, I think it goes to 19Hz.
I've just been looking at it for the last 20 minutes, dreaming.
I can afford it but it's just too noisy for where I live.

It's very very difficult to use a sub unless you have a proper monitoring environment/speaker set up.

Once I started using the HR824s my need for the sub dissapeared.
I head the VXT6s at XIs and even they are fine for low end monitoring.

its not a case of hearing those frequencys its more of a case of feeling them

To get down that low I'd be looking for a >12" ported or even horn loaded enclosure.

If it reckons it's getting anywhere below 40Hz as a single unit monitor check the price, reputation, and the actual quoted responses 20->20,000Hz @ +/-3db is some fuck off speaker whose price should reflect this. 40 or 50- ~20KHz @ +/-3db is far more likely.

As for actual club systems that could reproduce those freq's: LOL
The extra power/efficiency/amplifiers/cost needed to reproduce those last few Hz anywhere below ~40Hz to 30Hz become an almost holy grail for cabinet designers. Remember turntable rumble @ 33Hz/45Hz?! and the turntables resonant freq start coming into effect at such low freq's.

Big bass = big drivers + big boxes + big horns as a rule of thumb.

Good luck :wink:

Hope you have a sub amp that pump anything close to 20Hz. Bass shakers mounted on your furniture and a compressed air servo is about as good as your gonna get it.

Who was it that was saying you'd need a speaker 60 yards across to produce a 7Hz tone? :lol: That's rich.

it takes something like 50 or 55 feet for a 20hz wave to develop fully-- you got that kind of space?

you said you live in a busy area - surely if you are trying to hear 20 Hz in your bedroom, everyone near by is going to hear it too?

sorry mate, I didn't say I was going for 20hz in my setup. Like Decklyn says, it's very hard to monitor such frequencies unless you have ALOT of control over the enviroment you're listening in.

I live in a very muscal houshold where everyone is playing anything from dub reggea, disco, jazz, uk hiphop, grime dubstep garage to alt rock.
And we're pretty liberal with our volume settings, and this goes on from 10am round to 4am, at times.

So I meant it's too noisey in the sense that it would be like driving a nice car down a shite road, going nowhere special - by putting that sub in my room. hmm.

I mentioned low frequencies coz the Mackies already go relatively low, but I guess I just want something a bit more punchy going on in my listening.
