 The IRs themselves, we put a lot of time and effort and research into an in-house proprietary processing system to generate the best sounding IRs we possibly can. This isn't something that's easily recreatable, it's custom designed in-house. The space itself is fantastic with the huge log wall diffuser, it's giving us that energy back into the room, which is supporting the capture of the floor, especially a forewatch hole really fills the room there. So it's a combination of the the acoustic setup of the space with this cabinet, with the Celestial speakers loaded into it. That's feeling that room for the best capture, a couple of that with the mics in particular, the studio grade mics and the positions of the microphones which have taken a lot of time and effort into finding the best positions from listening tests. The close mics, I mean it's dominated by the response of the speaker itself so it's it's most important the speakers themselves sound top-quality in the cabinet of course because it's it's a collective system together. But there's always some reflection of room in there. We've got the room mics already which are filling in that room response. There's a serious amount of research in the process of creating the IRs both in the positions, the capture, the processing of the recorded data to generate the most effective and top-quality sounding IRs because fundamentally it's a listening process. It's the ones that sound the best that are the best.
