Strangemay times Clipto complained that the kit is bright. Maybe your taste and his taste differ a lot..

i would advice you to stay with the 691's but change your fronts to either 4inch components
Thanks for the suggestion bro but what i dont understand is why do you think the coaxials are bad or components can DRASTICALLY be better? I think those 4 inchers are giving good for their size. Why would the components be able to givew better mid freq resp? After all they just have a better crossover and the tweeter and main diaphragm are off axis.

What i think that the reason is one amongst the following: the amplifier, burn in time , the enclosure of the fronts.

Components makes lot of diffarance.It is not possible to reproduce entire audio spectrum in one single speaker/voice coil.

You are confusing coaxials with full range speakers.

a full range speaker has only 1 speaker which is supposed to reproduce the entire spectrum. A coax will have 2 or more drivers, and you can have co-axial ( having the same axis) only if there is more than one speaker
having said that, the 3,4, 5 etc way speakers arent exactly coaxials in the strict sense , lekin chalega

why comps sound better is because in the front , they allow you to place the tweeter with a lot more flexiblity and you get better sound reproduction. Also, they also have better crosssovers than your average coax.

On the other hand , if you place the tweeter right next to the midbass , they wont sound much better than the equivalent coax, especially if the coax has its own dedicated and high quality crossover , say like the JBL power series

So u think the coaxials have only one voice coil?

Think again CO + AXIAL. They are simply two different set of spekers*(main and tweeters), mounted in a way that both the speakers have common axis. This is done primarily to save space. And for the same reason the crossovers can not be made big enough and are very basic.

In case of components, sine both the speakers (main and tweeters) can be placed differently, they have the flexibility of having bigger crossovers with more refinemenets and thus vthe better quality.

Man dont just go with what everyone says, think rationally and logically.

And its not a rule of thumb that components are alwayz better than the coaxials. Everthing is subjective to a whole lot of dependant variables.

.

Also note the frequncey reponse with compos may be lower than the 85Hz that your polks provide.
(though by not much-but even so)

Another point is experience.
i have heard polk coaxials(not components)-i found them a little bright , in addition to my opinion i think another member has also posted the same feeling as me.
this might be giving you the feeling of lower mids.

ofcourse that may be corrected by taking the highs down and boosting the mids using your equaliser ( but im sure u've tried that already)

try amping the fronts with a JBL ( 3k is not much)
there is def no need to amp the rears- they are real LOUD

if you still not satisfied change the fronts

Dude in the first place, you just cant expect bass from 4 inchers. However low they may go on the paper, realistically speaking they just cant produce bass.

They are meant to compliment the front sound stage and thats cwhere the trouble is.

Anyway getting an amp for them is not a very feasible idea.

And one more thing. Being loud is no measure for SQ. My current setup is louder than my need. Also the 55rms fronts are definitely not lagging behind the rears, in loudness at least.

Possibly I am not being able to explain what i want to say. All i want is better SQ.

My friend i never complained for bass or sub 100hz response. I am complaining about the 800hz to 4khz freq band. I hope you get that even 4 inchers are comfortable producing that.

I am not confused.Even i have tried tweaking JBL coaxial XO and have got better sound after that. In fact if you can remove the tweeter and place them in different location /angle they sound as good as components.What i was trying to explain is in the same axis (sorry not voice coil -my mistake) they normally don't sound good.

No brother, Sorry for confusing statements.I would have read the statement properly before posting.

Here is the latest update:

I guess I do not need any amp or sub

O yeah ! I said it right. Believe me or not, the set up is getting better day by day.

I fiddled with the parameterised equalizers. Boosted the 60Hz band(for the subtle lows) and gave a little bump to the 500Hz freq (for more warm vocals). The highs are boosted at the 15KHz level so I am listening to only the subtle highs, not any shrills.

I drove from punjab to gurgaon, continuously for 7 hours, and listened to at least 200 songs (in bits and pieces.....was actually testing the set up than enjoying the feel of the songs)

Trust me, the burn in has a lot of effect. I remember listening to Akon's "I wanna love you" (This one track has really subtle low notes). The way it sounded about thee weeks ago is totally different from what it sounds now. I know i was really disappointed after listening to it previously and that was precisely why i wanted to go for a sub.

But folks the things have upturned. The polks are showing their power.

Honestly i am happy now.

Another track worth mentinoing is "Luka chhuppi, bahut huyi - Rang De Basanti". What a use of the strings. Hats off to A R Rehman. The song sounded so good that I literally heard it more than 10 times.

The same thing goes for yet another track by AR Rehman (Guru- Aye Hairathe Ashiki)

I made the fader settings to +1 for the fronts. And those guitar notes are so well reproduced...I am simply awe struck. How can they sound so good without doing anything ?

The fronts used to sound as if the sound is coming from bathroom, so subdued, so pressed. But the speakers have opened up after 40-50 hours of extreme operation :P

I'll update you guys again after a month (i.e. my next trip to punjab)
