BASS BOOST SWITCH, TRI-TUNED PORTS AND PORT PLUG

Enjoy Room-Shaking Bass the way YOU want it!

In designing subwoofers, engineers must choose between the tradeoff of 

1.

Maximizing Output (i.e., the loudest

a subwoofer will play) or 

2.

Maximizing the lowest bass frequency a subwoofer can deliver. Traditionally, the sub-

woofer engineer decides which tradeoff he or she thinks is best for the consumer. But the top-of-the-line Elite
Series Acoustech PL-300 subwoofer includes a “BASS BOOST” switch, “MAX OUTPUT” switch, Tri-Tuned triple ports
and a port plug to allow 

you

, the listener, to choose your bass preference. Enjoy exciting room-shaking bass below

20Hz (lowest audible threshold) you can only feel or set your PL-300 to “MAX OUTPUT” for the loudest levels of
bass! The PL-300 provides full range balanced tight bass as well as excellent transient response providing clear,
precise detail to perfectly match up with your other speakers which handle the midrange and treble. Until now,
this state-of-the-art level of performance was limited only to far more expensive subwoofers!

In the “BASS BOOST” mode with the center plug inserted, the PL-300 will deliver all frequencies from 15Hz to
200Hz (+/- 3dB) at impressively loud levels including frequencies below 20Hz which are felt, not heard. In the
“MAX OUTPUT” mode, the PL-300 will deliver even louder levels of bass for all audible frequencies from about
20Hz to 200Hz. Experiment to see which works best for you. For best performance in the “MAX OUTPUT” mode,
remove the PORT PLUG from the center port.

Frequency Response with plug in center port and BASS BOOST:

15Hz – 200Hz (+/- 3db)

Frequency Response with plug in center port at MAX OUTPUT:

20Hz – 200Hz (+/- 3db)

Frequency Response with unsealed ports and BASS BOOST:

17Hz – 200Hz (+/- 3db)

Frequency Response with unsealed ports at MAX OUTPUT:

24Hz – 200Hz (+/- 3db)

WHY TWO SUBWOOFERS ARE BETTER THAN ONE SUBWOOFER

Two or more subwoofers will naturally outperform a single subwoofer. The advantages of 2 or more subwoofers are:

• The ability to play louder with a greater dynamic range.

• More consistent bass throughout the room due to bass coming from more than one location.

• Even with careful placement, a single subwoofer will not have an optimal frequency response at all listening

positions in the room. Adding more subwoofers will result in a smoother frequency response at more listening
positions in the room, with less potential for peaks and nulls in the frequency response.

• Multiple subwoofers also help in reducing low-frequency distortion and offer improved dynamics over a single

subwoofer. This is a simple function of having more radiating area, plus more power on tap. Each subwoofer
works less hard for a given output level, staying comfortably in its linear operating range.

• Less work for each subwoofer resulting in a longer lifespan.

Two subs are better than one. You will also realize noticeable, audible improvements as you add a third or fourth
subwoofer, with diminishing returns after four have been well-placed and calibrated in the room. But, the step
of upgrading from one to two subwoofers will deliver the most significant performance increase. Once you have
experienced the benefits of multiple subwoofers, you will never want to go back!
