NHT HDP-2 Manual Do Utilizador
Thank you for your purchase of the HDP-2 Hybrid Dipole Surround Loudspeaker. Please take a few minutes to read
through this Owner’s Manual prior to installing your new speakers. The information provided will help you to obtain maxi-
mum performance from your audio system. If you have questions or need assistance at any time during the installation or
operation of your new speakers, please call your NHT dealer or our Toll Free Customer Hotline at:
1-800-NHT-9993
Please retain the HDP-2’s packaging to protect the speakers
in the event that you move or transport them.
Design
NHT speakers are designed to deliver refined, musical sound from attractive and affordable packages. Our efforts are guided by the
study of human hearing and are optimized for real-world use. Every NHT speaker undergoes rigorous testing and quality control at the
factory to ensure you years of listening pleasure.

The HDP-2 is designed to provide diffuse, non-localizable sound radiation when used as rear (surround) speakers in a digital 5.1-chan-
nel home theater system. The HDP-2 was designed with a natural tonal balance that allows it to be used in conjunction with any of
NHT’s direct-radiating speakers. It is an ideal surround speaker in rooms where the listening position is close to the rear wall, as it pro-
jects an ambient soundfield around the listener when placed directly to the sides of the listening area.

The HDP-2 is a hybrid dipole design which employs a unique combination of dipolar upper-range drivers that radiate sound in two direc-
tions, paired with a monopole woofer that fires toward the wall for low frequency reinforcement.

Placement
Prior to installing the HDP-2’s, spend some time considering placement options. For best results, mount the HDP-2’s directly to the side of the
seating position (Fig. 1). Place the speakers at a minimum height of six feet, to achieve optimal sound and to provide sufficient head clearance.
Mount the HDP-2’s at least a few inches from the ceiling. The HDP-2 is designed for indoor use only.

When the HDP-2’s are mounted on the side walls, it is very important that you mount the “right” speaker on the right side of the room
and the “left” speaker on the left side of the room. The “right” speaker has a small round sticker with the letter “R” on its back panel.
This is because the forward-firing drivers on the “right” HDP-2 are in-phase with the front (main) speakers in the system, while its rear-firing dri-
vers are wired out of phase and must face the rear of the room in order to avoid cancellation effects with the front speakers. Similarly, the “left”
HDP-2 features forward-firing drivers that are in-phase with the front speakers, and rear-firing drivers wired out of phase.

HDP-2 features forward-firing drivers that are in-phase with the front speakers, and rear-firing drivers wired out of phase.
Alternately, the HDP-2’s may be mounted on the rear wall behind the seating position, if the room necessitates this configuration. Again, it is
preferable to mount the speakers at a minimum height of six feet, and at least a few inches from the ceiling. When mounted on the rear wall,
it is very important that you switch the speakers around, using the “right” HDP-2 on the left and the “left” HDP-2 on the right. This is
done to ensure that the HDP-2’s radiate sound toward center of the room (listening area) in phase with the front speakers. Do not simply reverse
the polarity to the HDP-2’s as an alternative to switching them around. Reversing the polarity would put the HDP-2’s woofers out of
phase with the front speakers, causing cancellation effects.
