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 - Black 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!

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

My great room is a stretched octagon, about 18 by 24 with 18 foot ceiling. I have a ceiling fan on a 6 foot drop rod in the center of the room. Wondering if a ring of these just over the fan would work, with a sub tucked behind a sofa. Too weird? Thoughts

Asked by: himhimself

If I run two of these on each side for rear surrounds, Could these be Wired in an 8 Ohms Load if wired in Series!?.... Thanks! ~ Geo*

Asked by: Geostarr
Yes, 4 ohm nominal pairs wired in series become 8 ohm nominal. However you can experience interference effects from having the extra drivers close to each other... nulls and hot spots throughout the frequency range.

Are these speakers paintable?

Asked by: jungleb77
I don't see why not as long as you cover the drivers and connections to protect them.

Are these speakers suitable for hi-fi music or are they more for PA and ambiance music applications? I would like to use them to use them with a Lepai LP-2020a T class amp and a small (Dayton SUB-650) subwoofer to make a high-quality PC sound system.

Asked by: curlytail4legs
I think you will be impressed with the sound quality of these speakers for any application, but they are designed for commercial installations where they will commonly be used to provide background music, under-balcony sound reinforcement, or announcements. Another good choice for your desktop (particularly with a subwoofer in the mix) would be the new Dayton Audio B452 speakers - this is what I use at my office desk. They have superb balance for their size.

Can 4 of these be configured in the circle and be used as a true stereo system? I want to experiment with these using my keyboards in stereo at a small venue. I am hoping to achieve a pseudo Leslie effect. In true stereo. Or is it mono circular?

Asked by: kathnrich
When these are clustered together they are generally used as part of a 70 volt system which is mono. You could wire them as stereo, but I do not think it will be very beneficial. You can certainly experiment and leave feedback with your findings.

I need to drive 3 pair of these speakers in a dining / common area at a nursing home, mainly for movie night, occasional PA applications.  The room is about 40' x 50'.  What's a good amp to use?  It needs to have a couple of mic inputs as well as dvd/cd.
