Pure Energy Soundsystem (PESS)

www.epess.cz

Under the name PESS we continue to organize and promote electronic music parties. Musically, we like to focus on slower hypnotic repetitive beats with maximum BPM of 150. We’re not restricted to one music genre, but rather like to exploit and combine different styles of underground electronic music. When you visit a PESS rave, most often you will have a chance to dance to progressive psytrance,  and different subgenres of techno (minimal, deep, progressive, acid) with emphasis to high sonic quality of the records. Sometimes we collaborate with conceptually similar soundsystems to build sound walls of insane dimensions and power. Together with massive lightshow, decorations and video mapping, we’re capable of entertaining up to 1000 ppl solely with our equipment.

You can listen to some of our sets and production in the Music section to get a better idea of what we serve to the partygoers :).

We’re open to any collaborations and invitations. Go ahead and don’t hesitate to contact us.

Our current audio 4-way stereo setup has been completely hand-build by us using the experience we’ve gained over the 18+ years of running a soundsystem and building our own speaker enclosures. For subs  we employ the legendary Fane 18″ scoop enclosures from the 1980s which have been heavily modified to efficiently accomnodate the currently most advanced type of woofer drivers. The frequency response of each enclosure was simulated using the HornResp SW, prototyped, and analyzed using EMC8000 and REW SW. After some optimizations, we came with the final design. At this time point we have achieved the sound setup we’re finally happy with – optimal frequency response, extreme SPL, medium throw, low distortion, and sufficient headroom. This is the key for our ultimate listening experience.
