86後喇叭簡易升級

說升級其實有點牽強,不過是稍微動一下烙鐵讓這個小喇叭出聲而已。
這個喇叭音盆的尺寸只有一般三吋喇叭的大小,但即使是三吋也不該在音量轉到最大只有蚊子般的音量!!
拆下來看發現了一顆高音的濾波電容 3.3uf, 虧它還是個ELNA的高檔貨,在6歐姆的喇叭阻抗下,分頻點大概是在8KHz, 加上這又是個小紙盆喇叭,不是球形高音,難怪聲音這麼小又難聽~~

索性砍掉重練,把電容拔掉,直接把黑線焊在負極端子上當全音域喇叭用,BINGO,中音出來了,還算乾淨,雖然不能和改裝品相比,起碼音量,人聲都出來了。
由於鐵架的開孔太小,改裝喇叭的磁鐵放不下,只好暫時先這樣用,等有可用的改裝框架再來換好點的喇叭!!

該不會其他區域的86有配多顆喇叭
又沒考慮到台灣只有一顆
才會有這種詭異的設定吧?

也許吧,美國的FRS後喇叭看起來就比較好,起碼是正規的3.5"大小。

美國的FRS在後行李箱 左上角
有外掛一套 功率放大機
所以 他的喇叭 與台灣進的 是不一樣的
當然 這是美國市場的不同 才會有些許差異

的確,這邊有篇文章提到美版的Scion FR-S 有最好的音響配備,因為這是掛SCION品牌的賣點。

http://www.ft86club.com/forums/showthread.php?p=966584

Japanese, Continental, and Asia/Australian Toyota 86/Subaru BRZ all have 4 tiny dual-voice, single cone speakers, driven by a head unit of various varieties, all with very small amplifier even in the Limited package. This is true for all market Toyota 86 and Subaru BRZ, except the USA models. This as you say indeed, does leave a lot to be desired for a car trying to appeal so much to a very niche audience. And you are correct in accusing them of the lack of sonic detail. However, the focus in these market cars, especially in Japan, was to keep every single gram of weight off the car for the singular purpose of it being a sports car. So there is some saving grace on the reasoning...

Now, the USA market took an entirely different approach in product planning for the FR-S content, that also transpires to the USA bound Subaru BRZ for the sake of production variables staying rather consistent.

The Scion FR-S, and USA-bound Subaru BRZ, all have a MUCH higher grade audio systems because Scion, as a brand wanted this to be one of the big selling point.
Thus the USA Scion FRS has a specifically made head unit, by Pioneer Audio, that has over twice the output to the front channels, and a separate amplifier at the rear driving door and rear side speakers.

There are 8 speakers in all USA cars, in base form.
All of which have twice as large magnets than Japan/Continental/European models, and are all polycarbonate/PET cone drivers.
In total there are crossed over 2 way component speakers up in the dash (1 tweeter pair, 1 high-mid pair) and single low-mid pair in the doors, and 1 pair of long-throw low-mids in the rear passenger's seat.

The audio experience in the Scion FR-S is quite drastically different from a Toyota 86 outside of the USA/Canada. North American cars have very eloquent and neat voice character, and speakers are much tighter in feel, since the cones distort much less in shape while pushing air, the result is a much better timed and punchier, tighter arrival of sounds to your ears. Since the head unit has pre-set DSP setup for iQ, FRS, and tC, each mode with timed staging for each speakers and cabin environment it is also tuned specific to each car, adding to the overall efficiency of the system using all reflective overlap of noise within the cabin space.

And all of this, BEFORE we add the OEM Audio+ Reference 400 system audio as dealer option. These options add yet another amplifier, and replacement 2 way separate component in the upper dash, a recalibrated DSP amplifier DSP unit tuned by Sandy Lirag, a former Boston Acoustics lead home/vehicle audio engineer, and a tuned closed 8" long throw carbon driver subwoofer. And because OEM AUDIO+ is a third-party external company outside of Toyota, catering to the dealerships in the USA, and owned in partnership with the engineer, Mr.Lirag, the audio system is not a high-volume, marketing entity-based hype, and is a truly fine-tuned system with a taste for accurate audio reproduction using, pricing, and calibrating to his own satisfaction and not the production board members...
IN the FR-S unit, it is truly matched to the Toyota 86 driving concept of "Built by passion, not by committee." But Mr.Tada has a point too, in leaving this out, for the few kgm it saves the car too

它不就是一顆高音單體嘛?你降子拿掉會不會過載燒掉?:(

功率開太大是有可能燒掉的,不過我早就把它換成全音域小喇叭了!!
謝謝提醒。
