Lower Distortion With Vifa TC9-FD-18-08

It is been a long time I using Vifa TG9 here on my living room. I personally like the character of this driver playing simple music. The TG9 is a bamboo cone with 4 ohm impedance, while this TC9 is a paper cone with 8 ohm impedance.


I order them online and has been arrived around few weeks ago. I also purchased with several items for my next audio project. Spotted the 3 inch sub-woofer from Tangband:)

The package are so simple, only a cardboard and plastic cover on every driver I purchased.

The reason I highlight this TC9 is because it have the same spec with TG9. They are same dimension, same plastic basket, and same construction. The impedance is only make them difference.

For my F5 amplifier, running on class A, the distortion on 4 ohm are greater. Thus, the power output are smaller on 4 ohm. Speaking about efficiency, 4 ohm drain more power than 8 ohm and will generate more heat. So much waste on 4 ohm and this TC9 is the answer for all of the reason.

I will install them as soon as possible, but not right now. I am still evaluate several upgraded components. By changing the driver would be more difficult for me to evaluate the beneficial changing on my current upgraded project.

  1. Hello,

    Great review.

    BTW, how are these TG9/TC9 Vifas compared to local Indonesian car audio brand "Cello" (same code/type)? And if i may know, are yours are still danish made vifas?

    TIA & Cheers!

    1. Hi TIA, as far as I know when using cello product is actually a rebranding from many product. One of them is from Vifa. But that long time ago. Right now they put many Chinese product to their product line up.

      Danish made Vifa for TG9 is having the big magnet with stell cover on it. Please find my post about TG9 Vs. SB65 installed on Honda Jazz. The Danish TG9 somehow more relaxed sounding, more mellow in vocal but still maintain good high frequency compares to Chinese TG9. Those difference is slightly noticable, not huge.

OPA1622 Vs. OPA627 High Performance Op-amps Comparison

This op-amps comparison topic is actually boring, but at the same time, many of us still curious about what others think about it. The reason is simply because of the op-amps variation are hundreds and they are depends by the implementation. The op-amps are considerably cheap and an interchangeable electronic components but they are not built for the same function. So in this discussion, I will focus on the modern Vs. vintage high performance op-amps in the simple non-inverting pre-amplifier gain stage.

Vintage Multibit R2R DAC Tier List

At the very beginning of this year, I committed to explore the best multi-bit R2R DAC. This is simply because I have plenty of the resources (from broken old unit CD player of course) and ability to build them up. If you think this kind a recycle from old un-used unit to become something useful, than I should stated myself giving contribute for greener world:) After all DAC that I built in this year, I think it is better for me to list them up again in one single page like this. Then I will rank them up in a simple tier list. The reason for this, so you all know what my opinion about of those vintage multibit R2R DAC especially in the sound quality.

PCM56 R2R Non Oversampling DAC Built

From early this year, I am start to playing a lot with the multibit DAC. They are from Sony CDP TDA1541A here , Nakamichi DAC-101 dual TDA1541S1 here , Clarion DRX-9255EXL PCM1702 here  and Clarion HX-D1 PCM1704 here . What I said playing with them is actually more suitable words because none of them are built by myself. I only study and exploring those unit then make some upgrade especially on the power supply components, signal capacitors upgrade, and bypassing the unused internal circuit for more clearer yet natural sound quality. This upgrade make a lot improvement compare to the first time I listen from it and I can really enjoy what the designer from each manufacture deliver the sound they would like to perform in those units. Those said units are categorized as a parts of hi-end audio system and I really now familiar with the sound signature from each of them. But to be honest, I am not satisfy yet with this condition. Because none of them is built by myself from ground up. ...
