Your New Subwoofer
1.1
Unpacking
For most of the Danley Sound Labs line we recommend that it be unpacked by two or more people. Refer to the spec sheet for
product weight. Remove tape and open top flaps. Lay the box on its side and slide the subwoofer out. Remove the packaging
wrap.
1.2
Inspection
Check to make sure the product is not missing hardware of any kind. If any brackets or additional accessory hardware is missing,
please don’t hesitate to contact Danley Sound Labs.
1.3
Shipping Damage
If your subwoofer appears to have been damaged in shipping, please take clear photographs and contact Danley Sound Labs
immediately.

Understanding the Difference
2.1
THE TAPPED HORN
The Danley Tapped Horn Subwoofer™ is a proprietary design which allows us to build physically small subs which are very
efficient especially at the low end of their range and are virtually linear in their passband. Subjectively the TH series produce
very deep bass from generally very small boxes. They are unlike conventional horns in that combining multiple TH boxes together
results in more output, but not significantly more extension.
2.2
THE DANLEY BASS HORN
The PG218 subwoofer is a Danley take on a conventional design. The subs feature a front loaded, folded horn design. The subs
behave conventionally in that adding boxes together not only increases the output, but extends the low frequency response
downward.
Section 3
Initial Set Up
3.1
What Size Amplifier to Use
Selecting the right amplifier for your subwoofer depends on a variety of factors and uses. The owner is ultimately responsible for
choosing the best amplifier or amplifiers for the application. We recommend choosing an amp that is rated no less than continuous
and no higher than program. Please note “Continuous” does not mean “forever”! Most subwoofer manufactures, including Danley
Sound Labs, subscribe to the AES standards for subwoofer power ratings.
3.2
Connecting to the PG118
Your Danley subwoofer has two NL4 (“speak-on”) connectors located on a panel on the rear of the box. PG118 subwoofers are
wired as passive. The two NL4 connectors are wired parallel, meaning pins +1 and -1 on both NL4’s are connected to the same
circuit. Do not plug two amp channels into the two NL4 connectors on pins +1 and -1. Pins +2 and -2 are also connected allowing
a separate signal to pass through the input cable to pins 2 of the second NL4 connector, effectively turning it into an output
connector.
