![]() ![]() Once installed, and you are happy with your settings, it is recommended that you leave the EQ as it is, only making minor tweaks if you are not satisfied with the sound as a whole, as an equalizer is primarily intended to shape the overall sound of your car’s system, not to adjust it from track to track. When installing your car audio equalizer, it’s a good idea to refer to the manual and make adjustments incrementally, as you run the risk of damaging your vehicle’s audio system, if performed incorrectly. One exception is the Soundstream MPQ‐90, with its nine-band equalizer that offers even more precise flexibility and control over the source signal. When it comes to equalization configurations, most models, including the Clarion EQS755 and American Bass High End, have seven-band parametric EQs that give the user a wide range of tone-shaping possibilities, ranging from 50hz to 16khz. A higher output results in a crisper signal being sent to your subwoofer and speakers. Others, such as the Audio Control Three.2 feature a built-in preamp that boosts the signal, giving an impressive thirteen volts of peak power output. Most console-based systems, including the Sound Storm Labs S4EQ, Massive Audio EQ-7X, and the Earthquake Sound EQ7000Pxi, are passive, meaning that they run from the stereo’s amplifier and do not amplify the signal. When choosing an audio equalizer, consider your power requirements. The audio equalizers in this ranking are all made to DIN standard, meaning they conform to international aperture sizes for stereos, navigation consoles, DVD players, etcetera. It also allows them to “tune out” ambient noise associated with engines, wind, and road vibration in the interior of the cabin. A car audio equalizer enables the user to expand the tonal possibilities of their in-car sound system and shape the sound to suit their taste. I'm not completely married to these settings but this is how my HK is set for now.Factory fitted car stereos are known for having limitations when it comes to enhancing their sound quality, with most tonal adjustments confined to basic bass and treble controls, or preset equalizer settings for various genres of music. A parametric equalizer uses a preset shape, and adjusting the shape will adjust multiple frequencies at the same time. ![]() A graphic equalizer allows you to adjust everything by using a dial or slider. My measurements and listening were done at a standstill, but this is how I have my car set to start tomorrow's day in the office (my car). The two most common are graphic and parametric. This is how you adjust frequencies below the 100Hz band in the EQ. I believe the Bass level adjustment is a very broad "shelf" type, effecting all bass frequencies. For example, the 500Hz slider still boosts/cuts a 1kHz tone about 7dB. ![]() I can't help but think this is a byproduct from an attempt by the designers to deal with the first issue mentioned.Īs an overarching theme, I'd suggest experimenting with seeing how much "boost" you can apply to your 100Hz slider, and how much "cut" you can apply to 200Hz slider before it's too much for your taste and listening material.ĮQ has approximately 10dB of boost/cut per band.Īs expected, the EQ bands are fairly "low Q." This means they are broad less-than pinpoint adjustments. a newer version of: Eqfy Equalizer v1.1.4 with this Eqfy Equalizer you will hear the best sound ever from your existing car speakers, (only) in combination with an sp-mod mcu ofcourse, or similar mod, your musical songs notes will be heard from all directions in your nice car like a lovely singing birds in the early morning. Arguably just as significant of a problem is a big rise in the response just above 200Hz. I suspect this hole is from the midrange drivers in the doors not being able play this low of a frequency with any authority.Ģ. There is a deep hole in the response centered at 130Hz. The two major issues in the bass region are the following.ġ. Here a few bits for HK owners to chew on while I continue to get to know the system. I just spent a good part of an hour taking some quick measurements with a tone generator and SPL meter. ![]()
