130° of conical coverage reduces the number of loudspeakers required for even coverage in close proximity

UV-treated, high-impact ABS enclosure and ported baffle assembly

Tuned for added musicality and low-frequency extension down to 70 Hz (-10 dB)

Low-saturation, low-loss 70/100V transformer with 8-ohm bypass and rear-panel tap selector

4-pole Euroblock connector with loop-thru wiring located the rear of the enclosure

Advanced voicing filter sets using QSC Intrinsic Correction are available through either Q-Sys processing or CXD amplifier platforms (available separately)

[Bass-Reflex] Installed 8 of these speakers in a church of 500 w/ balcony. Absolutely phenomenal sound. The deep feature is fabulous. Great tonality and clarity, with warm lows. Plenty of overhead power. Very pleased with this purchase. Thanks B&H 5

[2] great sound,volume,light in weight.better than the 8.2 which kept breaking down... 5

[Passive] I bought these speakers to replace satellite speakers that had broken cones. The sound quality is very good for the size of the speakers but the bass response is not very good as you would expect from such small speakers. I have a sub woofer connected as well and the low bass response from these speakers is not a problem. 5

[16 W] We are a church and needed speakers for outdoor events, parties, dancing, picnics for about 100 to 200 folks. I called a friend who happens to install home sound and video systems in high end homes, big dollar systems and asked him what I should get. He turned me on to QSC and narrowed it down to the CP12 series for our application. There were other speakers that did more stuff but my friend the audio expert said Get the tool that does the main job very well and not all the gingerbread, it will last a lot longer. I did and wow the speakers sound great!!! 5

[12 lb] At home stereo set up, wanted to try new tech, noticed local rental joints are exclusively QSC (no passive speakers though). Ordered smallest QSC speakers - I liked their look for home and their 85 degree pattern; with the idea to return them if I don't like the sound . I employ them with a 200W Mackie amp and SVS-SB3000 sub, through a DDRC-24 Dirac Live room corrector. The result is very pleasing, and the Tannoys are now retired. There is more clarity in the sound and I can push more (a lot of) power into the system with the clarity still remaining there. I don't have to sit on the sofa to enjoy the sound, so 85 degree pattern is working well. Note they are not flat, they require EQ/DSP corrector. 5

[11.3 V RMS] We are very happy with our AD-S6Ts. They sound great and have good coverage while also not looking like an eyesore. Highly recommend! 5

[18 AWG] I bought 2 of these speakers to run out smaller workshop events with and to have them be the lead loudspeakers for our 500+ festivals where we rent 4-6 other similarly sized units. The vocals and cleanliness of music at nearly all volumes in unmatched. We love that these have a lot of manual controls (DEEP, flat, external sub + Vocal boost, normal) outside of the mixer to further tailor what we're using them for in any given set. Yes, these have the DEEP effect which adds a substantial amount of low end if you don't want to tie in subwoofers. Love them. 5
