To Tune or Not To Tune?

[mryikai]

Hi~ is there any car audio group to join so we can exchange knowledge etc?

@rickylahout of phase?

@richard_crl032 Bro, don't sabo me pls...😅

@mryikai there used to be quite a number of car audio groups. They may be less active now compared with pre-Covid time...

This 3 way crossover need to tune.

It has 3 jumper settings to tune crossover frequency and slope for mid bass, mid range and tweeter.

HDR-1: WFR X FREQ

LO: 500Hz first order to 2kHz and second order above 2kHz

MED: 2kHz second order

HI: 3.5kHz second order

 

HDR-2: MID LEVEL

HI: (position1 – far left)) – crosses over at 1.5kHz second order with 0dB attenuation above 4kHz

Position 2 – crosses over at 1.3kHz second order with 2dB attenuation above 4kHz

Position 3 – crosses over at 1.25kHz second order with 4dB attenuation above 4kHz

Position 4 – crosses over at 1.2kHz second order with 6dB attenuation above 4kHz

Position 5 – crosses over at 1.1kHz second order with 8dB attenuation above 4kHz

Position 6 – crosses over at 1.0kHz second order with 10dB attenuation above 4kHz

 

HDR-3: TW LEVEL (TW MODE –2nd, TW EQ-HI) The crossover slope and driver characteristics will result in a lower acoustic crossover frequency than the numbers below – typically 0.7 times lower.

HI: (position1) – crosses over at 12kHz second order with 0dB attenuation ref. 20kHz

Position 2 – crosses over at 11kHz second order with 2dB attenuation ref. 20kHz

Position 3 – crosses over at 10kHz second order with 4dB attenuation ref. 20kHz

Position 4 – crosses over at 10kHz second order with 6dB attenuation ref. 20kHz

Position 5 – crosses over at 10kHz second order with 8dB attenuation ref. 20kHz

Position 6 – crosses over at 10kHz second order with 10dB attenuation ref.20kHz

 

HDR-3: TW LEVEL (TW MODE –5th, TW EQ-HI) This setting gives a combination crossover that is 5th order below 4kHz and varies as listed for each attenuation setting. The crossover will acoustically occur between the 5th order frequency and the –3dB frequency.

HI: (position1) – crosses over at 4kHz 5th order and 12kHz 1st order, 0dB attenuation ref. 20kHz

Position 2 – crosses over at 4kHz 5th order and 11kHz 1st order, 3dB attenuation ref. 20kHz
