Yes Prem,
Yes Prem, the keyword here is "good".Hari, any good dynamic speaker plays bass correctly.

Most commercial speakers does that imo.If you're listening to a 'box speaker' that turns a 70Hz signal into 40Hz, you're listening to a pretty crappy speaker.
Though this answers my question partially, why do people in general get a kick when they hear an extra octave bass though its not there in the original score.
So i am at loss to know which one is correct? The artificial 40Hz which gives us a good feeling as it has a extra lower harmonic content or the accuracy of the OB speaker which plays as it is without the artificial harmonic content (read no boom)?
Will do this on the weekend and post results.
You could try this with a pair of dynamic driver boxed speakers too and see if X frequency sent to the speakers produces X - one octave frequency (other than the first harmonic freq), and at what amplitude with respect to the primary freq.
If you listen to a tabla they seldom go below 60Hz during a live listening without speakers. If the same is reproduced in a box speaker they sound to have some extra low end though it may sound very very nice and appealing.
I am convinced with the bass of my current OB and do not need anything extra. The bass, if there in the recording is accurately reproduced by these speakers and never felt the requirement for a sub woofer or a large OB bass only speaker. The main reason i don't venture into sub woofer is because it will be a nightmare to get the correct position in my room and even a bigger nightmare to sync it with my OB with no phase control. Moreover the living room is shared by other members of the family and i do not want to hijack their space.Hari, I am sure your are loving the single driver OB sound and have not yet ventured into 2 way OB setup with dedicated bass drivers.
There are numerous options for OB bass. I presume the moment you start delving into it, your perceptions (and your brother’s) will change.
H frame, U frame, PPSL or simple dual driver OB are few of popular ways to OB bass nirvana. However great sized room is one Pre-requisite.
All the converts to OB I know, have had envious systems both ported/sealed and TL and are die hard stereophile and now they love their OB setups....
The fundamental and harmonics will be there in both the live (without amplifier) and recorded (with amplifier) sound. Its been observed that harmonics are around -10dB in amplitude compared to the fundamental and the sustain and decay is more accurate in the live sound. In amplified music, the speakers are the major culprit in rendering these mainly because of their inherent design. The harmonic sustain and decay define the timber of the setup and usually gets messed up in the speakers if they are not designed properly. Its not only about having a response till 15Hz or below but how well the timber of the instrument is been delivered with proper wave envelop.I am not sure of the line in Bold. the fundamental tone of a tabla may be 60Hz but as we all know every sound wave has subharmonics and Overtones. hence the 60Hz will have a 30Hz and a 15 Hz as well as a 120Hz and a lot more and the combination wave of all of those frequencies is very unique to that tabla's 60Hz fundamental sound.( else a tablas 60Hz may sound the same as a Mridungams 60Hz which will also have the same harmonic frequencies but different amplitudes )
The speaker which can ideally reproduce the 30 as well as move air for the 15 is what will give that true realism of being there. I am not sure of how to get a 15 Hz or a 20 Hz without a Box ?
Thanks for sharing, as my hunch was almost correct by half an octave.

So that means that some colouration in sound is ok and acceptable. There is no point in trying to reproduce the original may it be amplifiers, speakers and interconnects.Recorded music is not the true version of the track. It is what the sound engineer intended us to hear. So if a speaker further tweaks it, to make it more enjoyable, then I find no harm in that. No wonder all speakers sound different to each other. Some listen to analyze, I listen to enjoy

I am not sure if the flat frequency response sounding lifeless is due to RTA software in your case.After some experiments in active tuning using mics and RTA software, I have noted that after tuning to a flat frequency response, the music sounds lifeless. .
No sir, it is not due to the software.I am not sure if the flat frequency response sounding lifeless is due to RTA software in your case.
But IME, the flat frequency response gave me more realism, live like performance, more holographic 3D sound stage, more organic mids and highs and more energy to the music. So there must be something else other than just the FR curve.
