Working in a home post editing bay on the LG EP950 and LG CX. The ultra fine monitor makes for an amazing cost effective grading monitor.

I love these hard hitting and affordable Stereo Integrity HT18v3 drivers in DIY Denovo sealed boxes. Terrifically calibrated and aligned with a MiniDSP 2x4 HD for a powerful house curve and running EZ bassEQ.

The JVC RS3100 well calibrated is an amazing thing to behold.

It's been a dream come true being able to build our family home theater. A solid 2 months went into planning and building in my free time.
The room is complete with Owens Corning 703 sound absorption treatment, Fabricmate Wall Finishing Solutions fabric track with Acoustimac, LLC DMD black fabric material, JVC projector, Silver Ticket 158" screen, and all DIY home built speakers/subwoofers.

I've calibrated the projector and audio system to reference standards using SpectraCal Calman and RoomEQ Wizard/ miniDSP. The sound performance in room is stunning.

I truly can't wait to get the opportunity to build another reference room like this for a future client.

Message Evan with any questions you might have about room design, build out, or A/V calibration.

Phenomenal results after this completely manual calibration on the JVC NZ8 tonight.
Inquire about an in person or remote calibration today.

105 nits on 158” 1.4 gain 2.35:1 screen is pretty amazing. These JVC’s are something to behold.
