B. IMPORTANT!!! Refer to the driver documentation to determine

whether to use a sealed or ported enclosure. If the manufacturer

recommends a sealed enclosure continue to step C. If the

manufacturer recommends a ported enclosure, refer to the tuning

chart on the back for porting procedures.

C. Connect the speaker leads from the woofers to the terminal cups.

Be sure to wire the positive to red and the negative to black.

D. Align the mounting holes on the driver with the recesses in the

Q-Ring. If necessary, rotate the Q-Ring and the driver to properly

align printing on the dustcap.

E. Using the supplied screws, securely mount the driver in the

enclosure. It is recommended to start all screws and then come

back and retighten screws to prevent the driver basket from being

bent or distorted during mounting.

A. Experiment to find the best location for your new subwoofer system. Subwoofers for hatchbacks can

fire either upward, forward or backward for the best sound. Positioning makes a big difference in

sound quality.

B. FLYING SPEAKERS ARE DANGEROUS!! Permanent mounting is not only the safest installation, but

usually produces the best sound quality too. However, if you decide to mount your speakers so that

they can be easily removed, there are many suitable types of brackets available at most hardware

stores. The key to selecting such hardware is to make sure that the mounting will hold the speaker

securely. Good luck and enjoy your new subwoofer!

Thanks for choosing Q-Logic! - the ONLY subwoofer enclosure with the Q-Ring (patent-

pending), a multi-diameter woofer mounting adapter that can extract optimum performance

from any driver you choose! Follow the 4-step instructions CAREFULLY to custom fit your driver

to the enclosure. YOUR INSTALLATION CAN MAKE A HUGE DIFFERENCE IN THE

SOUND QUALITY!

A. Using one of the supplied rolls, apply the foam tape to the back of

the driver. Use care to apply the foam tape so that all of the mounting

holes are COMPLETELY covered.

B. Place ring face down with tabs sticking up. Apply foam tape to the

back of the mounting ring against the inside edge of the

mounting ring.

C. If you know the mounting diameter of your driver, use the trim guide

to determine if you need to trim the mounting ring.

A. Place the driver face down on a flat surface. Place the mounting ring

over the driver with the locating tabs pointing up. If the mounting

ring does not rest on the foam tape on the driver you will need to trim

the centering tabs.

B. Using a pair of diagonal cutters or scissors, trim each of the 6

centering tabs. Recheck the fit.

Step 1: Prepare the driver and Q-Ring.

C. When the mounting ring fits against the foam tape on the driver,

the driver is ready to be mounted into the enclosure.

A. Place the mounting ring in the enclosure and align the arrow on the mounting ring

with the alignment mark on the silver ring.

Use this position for mounting drivers with offset

hole alignment. (see illustration)

QLH/T-1.2512sx/dx PORT TUNING CHART

No trimming

required for

these drivers

Step 3-B:

1. Round the VAS value for your woofer up to the higher of the closest values on the chart.

2. Look up the intersection of Fs and VAS for the woofer you wish to use. This number is the port

length in inches.

3. Many driver configurations will NOT REQUIRE PORTS. Please refer to your specific driver's

recommendations.

4. Using the port length from above, refer to the Port Tuning Frequency Chart to determine the

roll-off point of your system. IF THIS FREQUENCY IS GREATER THAN Fs, THE DRIVER MAY

PERFORM BETTER IN A SEALED ENCLOSURE! If satisfactory, proceed to step 5. If not, you

may want to consider a different driver, or leaving the enclosure sealed ( unported).

Consult your dealer if you are unsure about your particular application.

5. Cut all of the ports for your enclosure to the length on the chart.

6. These Q-Logic enclosures have a port plug installed from inside the enclosure.

7. When porting these enclosures you will need to remove this plastic port plug. (Do not cut the

carpet until step 10)

8. From inside the enclosure, unscrew the four screws holding the port plug in.

9. From the outside of the enclosure firmly press the plug in until it releases.

10. After the port plug and plug gasket are removed, "X" cut the carpet over the hole.

( NOTE: Do not cut the carpet out! )

11. The "X" cut in the carpet will allow the carpet to extend into the port hole and work like a

gasket for the port.

12. Push the "X" cut carpet down into the port hole. Slide your cut and tuned port into

the port hole.

13. Return to step 3-C on front page now.
