is there such a thing as tuning too low for a HT enclosure?? what would happen to the upper bass if you did that?

Specify what frequency range.

too low as in what freq?
upper bass as in what freq?

saY LIKE YOU TUNED down to 12 - 13Hz. what would happen?? would anything happen to the bass between 45 - 70Hz?? do you have to make a massive box for that low of a tuning??

Depending on the driver used, You'd most likely have a horrible FR.

Assuming your woofer allows good performance tuned low and across the midbass
region then nothing happens to the 45hz - 70hz region. But when you play both tones at
the same time you may have SQ issues. You may have some form of
modulation distortion. But this happens to any subwoofer system playing
two notes at the same time where the frequency different is alot.

For example, lets say you played a 20hz sine wave then feed the woofer
some midrange frequencies, perhaps someone talking. The voice will be
modulation akin to you talking into a spinning fan blade. The voice is modulated,
sorta like a stobe light effect. When the cone has to move alot, higher excursion,
it can't do 'delicate' [lower excursion] upper frequencies when it's trying to do both.

The best bass subsystem is really a two or three part design. One woofer
to play upper bass, one woofer to play lower bass and the crazy woofer
to do 10hz - 20hz. When you split the job amongst two or three woofers you
lessen the effects of modulation, big boost to SQ.

thanks thy, but i'm talking strictly HT subs, not left and right front speakers

Most people that make HT subs tuned low, ie 15-17hz are happy with just
that. They may cross it over at 70-80hz, no higher.

If you want something more elite, you split the HT sub into two systems.

The 10hz system and the system that handles the higher bass.

It's esoteric.

That's be my ideal.

i would like to do that too have a sub for 10Hz and then have another that does it from 35Hz to 60 - 70Hz.

For example;

The roto sub for uber low.

The other sub for the rest.

ok, now what if u tuned it low and put it in a car, tuned to like 20-23Hz. what would happen then? what would the sub sound like?
