suggestion for my accent audio...HELP !!

Buffetfan · 18th September 2005, 18:01

This is what I have in my car...and everyone who has heard is very satisfied with it...(Note : I changed my entire system...I earlier had Blaupunkt 2 way coaxial in front and Pioneer 4 way 6*9 in rear with Pioneer 7450 as HU)

JBL 606 CE (Components...6.5 inch) in Front and 936 E (6*9 coaxials) in the rear...Powered by a JBL cs 60.4 amp

JBL 1200 D dual coil Subwoofer powered by a JBL 301.1 monoblock amplifier...
Pioneer 7750 HU (gives separate control over front, rear and subwoofer)

MRPs are

JBL 606 CE =>6K
936 e => 4750 Rs
1200D => 5990
301.1 => 12500 (approx)
CS 50.4 => 9500 (approx)
all above are with BnW
7750 HU => 9800 (without BnW)
Fitting charges and additional wiring (approx 3-4 k)

the system sounds awesome....though the total expense here is slightly above your budget....

the sony amp is good but there is a definite distortation (maybe its is just my imagination) in a setup I have seen with a Sony speaker amp setup compared to what I have...

and yes... I have by subwoofer in the boot...my frined has his sony sub in infinity baffle (I mean free air) mounting on the rear parcel shelf....the bass I seem get is more rich and deep....

Both cars are same (baleno)...so I would say that bass does travel through the boot...a sub mounting on the rear parcel tray will mean that your parcel tray will develop rattles after sometime due tot he heavy weight of the sub...and having sampled free air mounting too.. I prefer the bass produced in the box mounted in the boot

I think comparing the Sony speaker to the JBL is a bit unfair. What did the Sony 6x9s cost?

The sub mounted as IB in a parcel shelf will perform very good but you have to make a MDF shelf and bolt it on the metal shelf with some damping material inside. Make sure you seal the shelf properly. So that there is no leakage from boot to cabin.

With the sun mounted in the box in the boot. You need more power to get bass in the cabin moreover the bootlid of cars like baleno are prone to serious vibration which is very irritating.

Subwoofer firing in cabin is the best option.

I would use a damping material between the MDF and Metal.

Low freq. have long wave lengths. I see no trouble getting bass into the cabin. the plexiglass sub (32mm Xmax) shown on another thread is a good way to have a box and port the bass into the cabin.

There is never a problem getting low bass in the cabin with subwoofer in the boot. Its integration with the mids which is a problem. As the upper bass notes gets absorbed in the boot itself. This causes bass to be distant and detached from the front stage.

Try in your home by keeping the subwoofer in another room and integrating with the speakers in your listening room.

my subs are XOed at 80Hz/18db. I did not expereince this but if your Sub is XOed at 120hz/12db I can see that the midbass will be absorbed.

in fact i find that one can always detmine the direction of the low freq. (despite talk about bass being non directional). I would love to have subs in the doors but that would be asking for too much.

so i find that 80Hz/18db is a good compromise. you can tell the bass is coming from the back but atleast it does not draw too much attention.

navin · 23rd September 2005, 16:41

yes i got 8" woofers XOed at 80Hz. they are only expected to reproduce the last octave or so. The object here was to relieve the smaller drivers from the lower octaves so they are not stressed.

Autophile · 23rd September 2005, 17:18

We also cross the subs at 80Hz. But my point is about integration of subs and mids where you dont feel the subs location.

In your car its not a problem because its Octavia and the boot is not really sealed from the cabin. In sedans its more of a problem

5400 with BnW (5 way) compared to the 3 way 6*9 JBL for 4750

navin · 24th September 2005, 00:17

wow! now you say it. the sony is a 5 way. all those hf drivers would make a mess. my guess is a good 2 way 6x9 would be better.
