Default Re: Question about passive and active subs for Atmos

The Dolby certification spreadsheet lists a whole bunch of passive cinema subs, along with the regular powered subs for recording studios. For instance, the Genelec 7382A gets us over the hump to be qualified, but the damn thing is $10.5k! Alternatively, we could go with something like a passive Christie S118LP that is around $1000 that also gets us over the hump in terms of power. We would also need an amp of course, but it is still a huge price difference at the end of the day. I know there are things like AES inputs and that sort of thing that make it more expensive,

I'm curious if there would be a huge difference from an listening/mixing perspective, with the nature of LFE, between the 2?

What are you getting for that extra $7-8K (after we get an amp as well)

Iīve just built a room using a Genelec 7370 for bass management and Lfe for the main 7.1 array. Also using a 7360 for bass management of the ceiling speakers. But our room is for HT, not for features. Whatīs the Dolby certification youīre applying for? We also have a MTRX, but donīt have the SPK card, as we opted to have the Genelec GLM to handle the whole setup, since itīs all Genelec speakers.
