Tweeter

[marogipo_7]

mga sir tanung ko lang anu magandang brand ng tweeter pang palit sa stock tweeter ng lancer pizza pie? saka ok lang ba kung rekta ko na lang itap ang tweeter or need pa ng diode? TIA!

1. Anything that fits your budget. Since tweeter lang habol mo, you'll be selecting from DIY drivers and mga "excess". Most car audio components comes with a midbass and a passive crossover pa kasi.

2. You can tap it to the stock wirings naman. It might be a good idea to throw in some protection in the form of a small-value capacitor between the tweeter and the wirings though (just to be extra safe).

gamit ko konzert tweeter ..at hindi po diode ung nilalagay dun NONPOLAR capasitors nonpolarity capasitor 2.2microfarad sa akin

[marogipo_7]

ah so ok lang po pala na rekta tap na siya? kapag po ba nilagyan ng diode lalakas ba ang tunog niya?

sir may picture ka diyan ng tweeter mo?

Not diode. Non polar capacitor dapat. 2.2uF.

No. A cap will not do anything that will affect its volume.

I don't mean to hijack this thread but since the subject is "Tweeter", I might as well ask...

If the frequency response of a tweeter is spec'd 4Khz-23Khz, and using the1st order high pass filter reference table from Passive Crossovers 4 Ohm Reference Charts, does this mean I have to use a 10uF bipolar capacitor (4Khz 1st order HPF) to protect the tweeter? Do I risk damaging the tweeter (assuming high crossover settings were accidentally or inadvertantly changed outside the freq response of the tweeter) if I used, say a 15uF bipolar capacitor (~2500Khz 1st order HPF)?

^the capacitor is not for protection. it is used as high-pass filter, i.e. it lets high frequency pass and blocks low frequency.

why need to block the low frequency? because (1) the woofer is already handling bass reproduction (low frequency) and (2) tweeters are designed and best used for treble reproduction (high frequency).

you will not damage the tweeter by using 15uF capacitor. by using 15uF capacitor, you are passing 2.5kHz and above frequency to the tweeter. because the tweeter is spec'd at 4kHz-23kHz, the tweeter will play 2.5kHz to 4kHz softly, i.e. below normal volume level.

what can damage speakers (woofer, midrange and tweeter) are excessive sustained power and overdriven (clipping) amplifiers; not the audio frequency being sent to them.

salamat sa mga inputs mga sir. ineenjoy ko na tweeter ko.. sulit na sulit ganda ng sounds..

4khz for a tweeter? That's pretty high. Most tweeters can play comfortable 3.2khz upwards on a moderate volume level with the more engineered ones going lower especially large-format tweeters which has a more robust voice coil and magnet structure.

The higher your tweeter HPF, the "safer" it is for the driver.

Red_one presented a good post. However, I will remind car audio folks that the only time you damage your speakers - whatever driver it may be is when you drive past its mechanical limits. That's only the direct cause of damage - the others are simply causal relationship. For example, give a subwoofer a 10W clipped frequency, it won't even be damaged even if the waveform has a lot of energy inside. Why? Because the voice coil can take the punishment.On the otherhand, a tweeter with its smallish 1" VC won't.

Yep, according to Polk Audio website, that's the frequency range of their DB line of tweeters (DB1001). Since I'm looking at ditching the passive crossover unit when I finally go active, I had to read up on how to keep the tweeter as "safe" as possible.

Thanks!
