Frequently Asked Questions - DBX208BPQ ESX

What is the impedance of the DBX208BPQ subwoofer enclosure?

The enclosure offers three impedance options: Parallel 1 Ohm, Serial 4 Ohms, and Standard 2+2 Ohms.

How much power can the DBX208BPQ handle?

It handles 350-450 Watts RMS in parallel or serial mode, and 2 x 175-225 Watts RMS in standard mode. Maximum power is 800 Watts.

What are the dimensions of the ESX DBX208BPQ?

The dimensions are 78 x 29 x 39/29 cm (width x height x depth).

How do I connect the subwoofer using the QuickConnect system?

Use the QuickConnect cable plug QC20 with open ends. Connect the open ends to the amplifier's loudspeaker outputs. Do not use QuickConnect and spring terminals simultaneously.

Can I mount the subwoofer enclosure in any position in my car?

It must be placed in a location that does not interfere with airbags, safety belts, or driver visibility. Secure it with belts or mounting solutions to prevent movement during driving.

What amplifier power should I use for best performance?

Choose an amplifier with 15-20% more RMS power than the subwoofer's RMS rating. This prevents clipping and ensures clean sound.

How do I wire the subwoofer in parallel (1 Ohm)?

Connect the amplifier to VC1+ and VC1-. Then connect VC1+ to VC2+ and VC1- to VC2-.

What is the frequency response of the DBX208BPQ?

The frequency range is 30 - 300 Hz, making it suitable for deep bass reproduction.

What should I do if I hear distortion from the subwoofer?

Immediately reduce the amplifier volume until distortion disappears. Running the amplifier into clipping can burn out the voice coil and void warranty.

Can I use the bass reflex port both front and rear?

Yes, the Flex port can be oriented to the rear (for sound transmission through a ski bag) or to the front (directly into the trunk).

ACHTUNG:

Choose a suitable location for your soundsystem, that neither the driver's field of vision nor the security of the inmates will be affected. This stands also for airbag-zones and safety belts. The permanent temperature of the location should not be lower than 5°C and not higher than 50°C. Protect the device from moisture and humidity.

Ensure that your subwoofer enclosure will not get loose during the drive and hurt someone in the passenger cabin. It is recommended, that you mount the subwoofer enclosure with suitable belts or any other mounting solutions in the trunk area.

Please observe not to damage any serial components of your vehicle (airbags, wires, gastank etc.) during the installation of your soundsystem by drilling or any other operations.

For your personal concerns you should choose a appropriate sound level for the subwoofer enclosure, that neither the roadworthy of the driver nor his concentration will be disturbed, that he is able to notice possible traffic noises and acoustical warning signals.

Modern car audio soundsystems provide very high acoustic pressure beyond the 100 dB mark. Please observe in this case, that permanent use of high sound levels may cause damage to your ability of hearing.

Please ensure by any means the correct polarity of all connections. Faulty installed and connected devices may get damage the vehicle and the device permanently.

Please check in any case the operation guide or wiring manual of your amplifier which you'd like to use for the soundsystem.

Never connect the speaker terminals with the 12 Volt power supply, otherwise the speakers may get damaged.

POWER RATING

ESX subwoofer enclosures are designed for high bass levels. Anyhow it is possible, that unsatisfying sound characteristics could be caused by too low or too high amplifier power. In certain circumstances this even can cause a damage to the loudspeakers.

It is recommended to choose rather a more powerful amplifier (ca. 15-20% more Watts RMS than the max. RMS power rating of the woofer) and to use the amplifier not at the maximum output level (low distortion factor, good sound characteristics). A weaker amplifier at the maximum level causes worse sound characteristics due to the higher distortion factor.

Never crank up the output volume of your amplifier to the maximum level or run the amplifier into the clipping range. If the sound is distorted and not clean, turn back the level until the distortions disappear.

ESX subwoofer enclosures have no integrated limiter or clipper, which is limiting the level upwards. Overamplified bass peaks leads inevitably to a burn out of the voice coil of the woofer. A burn out of the voice coil, caused by clipping/overamping is not covered by the usual warranty.
