Dayton Audio QS204-4 Quadrant 70V / 100V Indoor/Outdoor Speaker Pair with 4 Ohm Bypass - Black

Great sound goes full circle with the sleek, modern design of the Dayton Audio QS204-4 "Quadrant Speaker." Developed for commercial applications requiring high performance and high style, the QS204-4 speaker allows virtually endless possibilities for mounting and installation via its clever multi-angle mounting bracket. Thanks to the expertly tuned acoustic package of dual 4" poly-cone woofers and 1" treated dome tweeter angled for superior dispersion over a wide area, the QS204-4 delivers punch, presence, and clarity normally associated with high-fidelity loudspeakers for the home.

The sturdy enclosure of the QS204-4 is made from weather-inert and UV-resistant ABS plastic, with integrated aluminum grill to prevent pest ingress or foreign object damage. A concealed structural matrix behind the grill material prevents denting from impacts. An internal 70V / 100V transformer makes these speakers fully distributed-application ready, and a convenient front-mounted selector switch behind the removable grill makes it easy to set the right audio level, or to select 4 ohm operation for use with stereo receivers and multi-room amplifications.

The included multi-angle mounting bracket permits mounting one, two, or three QS204-4 speakers at 90 degree intervals in either vertical or horizontal orientation, for true application flexibility. Mount two units together on a wall to create 180 degree coverage, or install a single unit vertically in the corner between a wall and a ceiling for a stylish "sconce" appearance and wide dispersion. Using the optional QS204PB 4-way pole mounting bracket, you can even create a 360 degree ring of quality sound in an open space.

Dayton Audio QS204-4 Quadrant 70V / 100V Indoor/Outdoor Speaker Pair with 4 Ohm Bypass - Black
Dayton Audio QS204-4 Quadrant 70V / 100V Indoor/Outdoor Speaker Pair with 4 Ohm Bypass is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Great Sounding SpeakersI got a pair of these from Parts Express a couple of weeks ago for our large deck and pool area. I'm using a 15 watt receiver. Last weekend we had a large outdoor party, about 60 people. Just two of these handled the crowd very well. Everyone could enjoy the music and the sound was crystal clear. Although we used them for background music for the party, I can tell you that these will really crank out the volume! Great speakers!

I'd like to use these for a music system in my plant but I would also like the ability for the music to cut off and use as a intercom system as well. Is this possible with these speakers and a certain amp? Or other hardware you sell?

Asked by: fantaxp7
Yes these speakers will work for a system like that. You will need a 70 volt amplifier with paging capabilities. The size of the amp will be determined by the total number of speakers you want to use. Please contact our tech support for more help with this question, tech@parts-express.com or 800-338-0531 x1.

Does the 70 volt option allow you to run 2 speakers on one channel?

Asked by: Kawboy22
To operate 70v speakers you need a 70 volt amplifier in which typically has a mono output. The amount of speakers that can be operated depend on the tap of the 70 volt transformer on the speaker and the amplifiers output. The sum of the tapped wattage should not exceed the amplifiers total output.Example: 100 watt amplifier can power up to 10) 10 watt speakers.

How big of an amp would be required to handle 20 Dayton QS204-4 Quadrant 70V / 100V Indoor/Outdoor Speaker?

Asked by: Jeepcowboy
This depends entirely on the taps you plan on having the speakers set to. You generally want to use about 20% more amplifier power than the tap settings add up to together. For example, if the taps on all speakers added up to 80 watts, you would want to use an amplifier that produces at least 100 watts of output power into 70 volts.

Could 2 pair of these Dayton quadrant QS204 spkrs. be used to build a small FOH PA system for really small venues (home music rm., small church setting, etc)?  IOW, basically like the Powerwerks or Fishman active systems except using an external amp? 

Asked by: Pops82753
These will work for a small venue assuming there is a high pass filter applied to help limit excursion on the woofers.
