The lowest frequency driver?

[blake_mooney]

I am currently looking for a large subwoofer that has the lowest frequency possible. The lowest I could find was an 18" driver made by Tumult that goes down to 15hz. Anyone know of any that go even lower?

Most any sub woofer will go much lower than that. It depends on what kind of enclosure you use.

If the enclosure and speaker are tuned to 10Hz, it'll go that low, even though the speaker has a higher rolloff..

It'll definitely be less efficient, but will still do the job.

Because I love a sub that can hit really low frequencies, why do you think? No offense, but your post was totally pointless and not constructive at all.

Bag End makes subs from 10" to 18" that will go down to 8hz flat with the use of the ELF integrator.

Otherwise...use a servo drive.

Oh awesome! You wouldn't happen to have a link would you? And do they sell just raw drivers? I'm not looking for pre-built subs...

Btw, what is a "servo drive"?

No offence, but anything lower that 15 Hz is pointless, because:
1. You cant hear anything lower than 25 Hz, only feel shaking.
2. There is no recorded sounds at anything lower than 15 Hz.
3. To make some good SPL at lower than 15 Hz, you need transformer station with current od xxx Amper.
4. If you do it anyway and use xxx Amper to shake it, you can put in danger your house.

I have a theory:
The really LF content excites harmonics in the structure itself causing the perception of the super low fundamental but tailored to your own space. I think this is where the air and extra soundstage that having good LF reproduction comes from.

There is no other way of exciting the natural harmonics of a fundamental in your house without being able to produce the fundamental at the proper volume.

My turn :
1. You can hear anything under 25 Hz if it's loud enough. Look at Fletcher Munsoon curves. BTW, feeling bass is nice also, even if you don't hear it. It's more realistic.
2. There's recorded sounds under 15 Hz. Telarc 1812 overture for example and SEVERAL movies.
3. I agree with you, you need alot of power, or lots of woofers with moderate power.
4. I agree with you, but worth the risk.
