If you use balance, you will imbalance the subwoofer.

You meant to say "stereo" subs? If it is mono sub, then I think it can be balanced again, no?
(I assume you are not talking about mid-woofers of front speakers themselves)

LBM, as Abhinav pointed out, it all started with both tweeters facing towards a single listener. So, it is not dead horse, probably a newborn yearling.

Didn't get you.

Even if there is one subwoofer (whether fed mixed mono or stereo, it is irrelevant), if you shift balance the subwoofer level will reduce.

I meant whether to call it gain or trim is a trivial matter. +1dB = -1dB trim, similarly +1dB trim = -1dB gain.

Yes, mono sub level will reduce. but you should be able to easily correct it by using say mono amp's gain. That's what I meant by "it can be balanced again".

Frank: That's a lovely setup of the pods. Workmen ship is awesome.
There is a CIVIC with pods in the front quarter glass in our forum. That is also a awesome mod.

[gigy]

Frank, i suppose you are not using rear speaker as of now. how about using one of its area for a tuned bass port for your subwoofer in box in box design?

@ Frank Mehta


Sirji, may we now know the price of those tweeter pods.

[MonkeyMan]

What an amazing job, Congrats Frank.
If you dont mind me asking, what was the price for the whole thing including the Hardware and Installation??

thanks! i believe that's M4uGr8's Civic you're talking about. It's pretty amazing too!!

You got me interested! Please elaborate!

I STILL havent got the bill from Ajay Kamath. Looks like A2ZAudio is doing charity nowadays

I have decided to keep the amount of the equipment under wraps for personal reasons, but yes, it was pretty astronomical. Totally worth it though, and the fact that I no longer wish to upgrade, says it all

The installation was in the higher 20's alongwith damping, and there is still the bill for the tweeter pods to be settled.

[MonkeyMan]

Frank, My sincerest apologies if I asked too much. Honestly I loved your setup so much that i thought i would get the identical thing in the near future. I mean one of the best cars around with such a nice setup, You have one Collector Item in your Garage.
However could you let me know some person in Delhi who could do such stuff?? I am from Ludhiana and over here I dont think anyone can do what you have got done.

[frankmehta]

no hassles bro. I am not hurt or something. LOL.
Thank you so much for the compliments man. Anyway you should try going to LBM (Faridabad) or Gyro (Motinagar, Delhi) for installation.

[frankmehta]

A small addition is about to happen tomorrow.
Will update this space with pics.


PS: it is not a guessing game. Just a minor bolstering of equipment.

[gigy]

How is your car's rear tray arrangement now? have you put in a new mdf board or have you put in grills in place of rear speakers?

[greenh0rn]

Guys, Gigy, this may sound OT but I guess even Frank would identify with my problem- I have my subwoofer in a sealed box in the boot of my Santro (hatch), and on top of that lies a very heavy MDF tray - the ones that are pre-fabricated for a pair of 6x9 and an IB sub (don't ask me why I got it in the first place). This tray still has 6x9 speakers on it (no sub), they are disconnected though.

Now for the problem- I feel that bass is muffled, muddled, or doing both in various songs sometimes. To address the issue, I pulled out the 12" lid that was latched to the hole to "try and get more bass in the car", I think this has helped a bit, but I still feel bass is muddled. On some bass heavy songs (try Moby's Bodyrock), I being on driver's seat get a feeling that I am sitting in a different cabin, and bass is coming from a different room!

Why is this happening? Are my 6x9 speakers mounted on the MDF tray acting as very poor passive radiators? Is the heaviness of tray the culprit? I thought of a solution- to get a MDF wireframe made that fits the contours of my parcel tray, but instead of any wood or solid material in the center, to use black cloth as a wireframe-wrapper. Do you think this would solve my problem? Or is there any other suggestion? I just want the damn low frequencies to move around my seat more freely

Hi all!!

I have gone and done it ONCE again :-(
Here's an idea of what I did today while shopping.








1. Morel Tempo 6*9 CoAxials
for the rear shelf (finally: here's the surprise. Rear Fills. See? I told you it was not a major jump in terms of equipment!)





2. JBL GT5-S644 4 Channel Amplifier for the rears. Someone will ask. Why a 4 channel amplifier for the rears? My answer is simple. The rears are rated @ 140 W RMS continuous. The new JBL GT5-S644 gives a super 70*4. I will be bridging both channels and powering the Morels. That will thus be able to provide more mid bass and bolster the highs. (this was what I meant by the 'bolstering' part all along)




3. MX 10 Feet RCA Cable for the Morels





4. My Shaldan Perfumes for both cars




5. Pioneer DEH-2190UB for the Zen (which is getting a slightly better audio system than already was)

STILL TO BE PROCURED.
6. Illusion Electra 5.1 for the Zen.



Wallet Empty. Period.

[Gilead]

Congrats dude! I think you need a 'fix' every 6 months or so, right?

Aren't the Fiesta rears 5x7? Planning to use spacers? How much are the Morels if you dont mind me asking.
