Do you think you need a subwoofer?

Dear Downunder: With all respect, if Sirspeedy till today don't understand or can't or don't want it the whole subs subject: like you say: " I do not for one minute pretend to know much about subwoofers as I have only had the sub for less than one day and bought it quickly. "++++

you IMHO are not wrong but totally loss/stay. You have to re-read many of what other people alredy post here ( including some links ) to learn about and through that learning excersice you could understand about and affirm " things " on the subject with know-how not before.

Of course, like this time, you can follow other person way of think but I think that you can do it a favor to your self if you really understand the subject of what you are trying to talk and trying to " understand ".

Regards and enjoy the music.

Dear Downunder: +++++ " justice and move the speakers out from the corners. " +++++

who told you that my speakers are at the corners?, please read on my virtual system about ( room measures/shape and speaker position ).

This is the trouble when a person follow other one with out know-how ( read ). Again please read carefully before you write something with out sense.

Regards and enjoy the music.

Dear Sirspeedy: What Gregadd post ( thank you ) could help you:

+++++ " I remember when I ran my ML CLS full range. That big panel could bee seen moving back and forth trying to reduce bass notes. With subs it barely can be seen moving at all " +++++

this should be enough to understand the whole subs subject ( Physics laws ) or at least to understand what means IMD/HD and the paramount advantage to lower those IMD/HD: that is a problem with your speakers and the Downunder ones.

Regards and enjoy the music.

Dear Sirspeedy: +++++ " To have a ported sub design substituting for "some" mid bass frequencies,that a good main speaker already has is tantamount to " +++++

maybe I'm wrong but I remember that your REL is a ported design, maybe your choose was not so good.

Regards and enjoy the music.

Dear Mark: I'm sorry to go on but your post is full of misunderstodd about IMD/HD: one of the worst " stages " for a high IMD are the two ways speakers where the " low " driver has to work from around 2K-3kHz down to 30-40 Hz !!!!

+++++ " Raul you are also incorrect in stating "servo bass" is the best.These types of systems(I've owned one or two)do not provide miracle cures.They are an alternative design concept,with their own advantages,and disadvantages. " +++++

I never talk of any miracle cures ( where is the illness? ).
Take a look of the velodyne servo design:

+++++ " Velodyne’s patented High Gain Servo technology
accelerometer that delivers a digital representation of
cone movement that is checked up to 15,800 times
per second ... " +++++

not bad eh?

Velodyne sevo design disadvantages? because is a servo design, that you have to tell to the Velodyne people and certainly explain them the disadvantages of their design.

I don't know if you are taking advise of some one on the whole subject but if you are doing that IMHO that kind of advise were/are with a very low almost non know-how and if you are not taking any other advise then I recomended ( with all respect ) that you do it and take it from everywhere with the right and in deep know-how and share with us that know-how.

Mark, I already told you:

+++++ " Please read carefully, I only want ( I would that ) that you understand the whole subject concept, if you want to aplicate or not is a totally different subject. " +++++

the only reason that I can see for you continue to post about is that you just don't understand, now if you did ( understand it ) then I can't unserstand anymore your last post.

Please let us know if you understand or not.

Now, if what you bother of my posts are that I say that " servo are te best ones " or that two subs are better than one ( to even and smooth response ), then I change it adding the word: almost, anywhere you like it.

Regards and enjoy the music.
