Suggestion + Upgrade my system

[smreddy]

Hi,

My exisitng setup to my accent is Pioneer HU 6850 JBL 937, Infinity component speakers + tweeters. When i increase the bass, i get lot of thuds in front due to components. Suggest how to get rid of this ?

How will sony 504 amp make difference to the exisitng system?
If i get ampl installed will i require woofer or sub woofer?

Appreciate your help.

cheers,
srinath

Hi!

I assume you are using the components in the front with no amplifier. You need to use a HPF (High pass filter- cut at about 80-100 Hz).
I think you can also do this with your HU. Read the manual.
Adding any amplifier will make a big difference to the quality of sound. The Sony 504 is a decent VFM amplifer.

Having a subwoofer is your choice. It will complete and round off the bass/bottom end of your sound well.

SAM do you mean to say that a following kind of system:

Decent HU + Front comps

will sound better as in better base\treble\Clarity if its powered by an amp ?

I am asking becaue a friend would be going for a HU + front comps setup & he values SQ over SPL & I was wondering if putting an amp would be any good as my friend thinks & so do I that it will only increase volume which he doesnt want.

[Sam Kapasi]

If your friend is using ONLY front compos and a HU, he will surely feel a lack of Bass.
However that said, he isn't entirely wrong. If the volume is low, you may not percieve a difference.
In fact if you buy a really cheap amplifier, at low volumes, you may find your HU (if it's a nice one) amplifier to sound better. But yes, at slightly higher volumes, a nice amplifier will improve the headroom, tonal quality and reduce clippping etc. Overall make the "feel" of the components better.

Often you miss it onl after you are used to it. Case in point my Father in law has an alpine HU and 4 JBL 636 in the 4 doors of his Swift. One day I added a small 2ch. amp and a pair of Blau 6.5" woofers (u dont call 6.5" drivers subwoofers) and he felt the difference not only in the bass but also the JBL 636 were sounding cleaner (since I had activated the HPF and they had to produce less bass).

Then I removed the Blau subs and he hated it. He told me that untill he heard what a sub can do in a car (and the Blau 6.5can hardly be called subs) he did not know he'd miss them so much. So now I'm putting them back in.

Hmm So which one of these Configs would you guys recomend:

1)
HU(Pioneer)
Front comps
2 channel amp

2)
HU(Pioneer)
Front comps
Rear Speaker(any decent make which are not expensive like the pioneer 6X9)
4 channel amp

3)
HU(Pioneer)
Front comps
4 channel amp
A sub

The idea is to have a system which is not too expensive yet can be blasted once in while but would mostly be used for not so loud listening with SQ

How are the 2 channel amp from Sony(they are kinda cheap so asking)

I hope I am not stealing this thread

[rsjaurr]

Technocrat,option 3 would be best one for ur needs,though most expensive of all followed closely by 2.

[Tool]

hey technocrat.. umm go with option number 2.. because in option number 3 you havent included anything for your rear fill.. for the time being i'd suggest going with compos in the front.. co-ax in the back and a decent 4 channel amp... later you can upgrade to a subwoofer and use the rear 2 channels of the amp to run the subwoofer and the rest 2 channels to run the front compos. and then you can use the Hu amplifier to power the rear coax speakers..or here is another option.. keep the 4 channel amp running the speakers front and back.. and later buy a cheap 2 channel sony amp and subwoofwer.. you can run the sony in bridged mode to power just the subwoofer...
hope this helped.. boom

In the above options i would ask you to go for the 2nd option as option 3 without Rear speakers would'nt sound good...

[speedzak]

JK's second option is the best! And add a sub later.

If you're very much in need of a SUB rather than rear speakers, then option 3 looks good! And add rear speakers later.

For an overall round and filled soundstage, you need some rear fill. Even a normal 6" co-axial will do the job.

BTW, why has JK mentioned HU with the setup? He owns a 6850 is'nt it??

[jkdas]

its for Techo not smreddy

for smreddy a 504 driving frnt compos set with HPF at 80Hz and a sub driven by bridged 2 channel of teh 504 in LPF at 80Hz would do.

[smreddy]

Currently HPF is having null, will change to 80hz and check it out. What exactly does this HPF mean?
How much does the 504 amp costs? Will there be any major wiring required for adding the amp? I am planning to get this installed on the wooden plank holding the rear speakers. Is this good enough or have some other suggestions. Should the amp be connected to all the speakers ?

[Sam Kapasi]

HPF= High Pass Filter. Allows the highs and mids to get through, stops the lows (bass)

1. the 504 runs about 4-5K
2. it has 4 channels any 2 of which can be bridged so you can make it a 2, 3 or 4 channel amp.

common configs are: 2 ch mode for 2 subs, 3 ch. mode for 1 sub and a pair of speakers (either rear or front) and 4 ch. mode for front and rear speakers only. You cannot connect 1 sub and 4 speakers to the 504 safely.
