I also realise the I like my sound more laid back than most people.

I find that the mids and highs from the 5750 suits my listening. I'm into a lot of alternative and amplified mids sound good.

I was considering JBL components for the front. I was wondering how that might sound. A subwoofer is in the distant future. Will the sound be too forward without a sub for the lows???

I did not particularly mention any amplfied mids as the reason to prefer a 5750 over the others. I believe it sounds flatter.

You always want the sound to be as forward as possible, sub or not. The idea should always be to have the sub match the front speakers as much as possible in agility, frequency and spl integration so that the sub doesnt drown out the front speakers, is right there when a low note is produced that the fronts are incapable of rendering, and sufficiently matches the front speakers in speed of delivery, so you dont get a detached feeling in the two spectrums.

This is a bit off-topic probably but I cant help mentioning that irrespective of what sub you choose, due to the vast distances that the sub and fronts are usually set apart, there is always a delay in the arrival of the sub's frequencies to the listener relative to the closer fronts. Add to that the poor impulse response time that a sub exhibits and it's almost impossible to keep the sound 'forward' and not giving a feeling of having the bass guitarist in the trunk. Electronic correction aids the cause to a great extent, but can go terribly wrong if not implemented properly.

Anyway, where the hell am I going here? time for a break.

B&T this is why some HUs allow you to time delay the speakers to match the bass. This does not help fully but can be a simple panacea.

That was the electronic correction I was referring to. And that's exactly why I love my Alpines.

Can I do this with the 5750??

navin,this what i did yesterday with settings on my HU.

As everybody here knows that bass should 'appear' to be coming from front,i set subw time coorection settings to zero, though i like also initial setting of subw time correction,set earlier with other spk.

Though i am yet to listen my system after i made this change in settings.I wanted to ask this few days back but i thought this wud be a stupid question.

Of course boss. It's easier with the 5750 than with any Alpine.

All ya gotta do is pick up the sub from the trunk and put it on the front passenger seat. Works like a miracle...almost!! Tee hee. Just kidding!

Hi BT,whats electronic correction??

[Autophile]

Electronic Correction = Time Alignment = Delay

Electronic correction is electronically delaying your front speakers (or rear.. or both) so that it compensates for the delay in time of the sub's arrival.

Simply put, typically, since the sub is far, and front speakers are nearer, the sound from the front speakers reach your ear first, then the rear speakers and finally the sub. So a device with time alignment will alow you to delay your fronts a lot and the rears a little bit so that you dont feel like the bass from the sub was heard a good few milliseconds after the mids and highs. Ideally, you would 'advance' the sub rather than delaying the speakers, but you can't do that cos everything's playing real time, right?

Auto Time Alignment
Pioneer's innovative Auto Time Alignment automatically shifts the soundstage in front of the listeners, bringing out the vocals in the process, to create the optimal in-car reproduction of your music. Using the included microphone, it estimates the delay from each speaker to the listening position and adjusts the speaker sound output timing accordingly. The output timing for each speaker is adjusted precisely so that the sound from each speaker, wherever it is installed, reaches the driver's ears at the same time, thus optimizing the listening experience.

If you do it using the supplied MIC .. there is a noticable difference in the sound. Whether u like the "Automated" result is a different question.

Even alpines have this dont they ?

[navin]

i dont think the older alpines 9830-9833 came with a mic. I doubt if even the recent models do. but i find it better to use your ears than rely on some external object.

Ears are the most sensitive instruments we've got.

[Xtreme Torque]

right navin. but for newbies, the auto eq and TA is the best thing they could ask for.

oh...i thought time alignment & rlectronic correction r two different functions.
But BT front left spk has only slightly less distance than subw.Its left front and left rear which r comparatively much closer than subw.

As i wrote earlier,same thing came to my mind.
As lower freq takes longer to travel i thought of setting TA for subw to zero [ earlier it was 0.3ms as against 1.4ms for front R and 1.3ms for rear R].But i dont think changing it to zero from only 0.3 will make much difference.

JB & navin,waiting for ur comments.

my 9853 has no mic and i dont think any of alpine has it.

Cool. I think I will place a sub on the front seat and two on the rear sets. All my passengers can sit in the boot.
