Hey guys -
New here and stumbled upon the GR-Research website last week while researching options to finish up my basement Music/HT setup.
I have a few questions on the NX-Otica and servo sub kits I couldn’t find complete answers on in the forum so I’m going to drop them here (I did see the flat pack and cross-over assembly options which looked very helpful).
Backstory: I don’t consider myself an audiophile by any means but set out to create a DIY music/HT setup about 5 years ago (different house at the time). I went with Jim Holtz Statement II’s based on reviews and they came out looking and sounding great. I love them so far. I have all of the boxes assembled and painted with some fancy BMW automotive paint but only the two towers are fully completed with speakers and producing sound. I’m just now getting ready to order parts for the center channel and rear surrounds along with 2 music subs to go with the towers to finish everything up. Along with an upgraded amp for the front speakers I’m looking at a 5-6K budget for everything.
No flatpacks for these at the time so I thought they turned out pretty well. First and last project cutting MDF at home for me – the dust was killer

Before pulling the trigger I wanted to see what other types of DIY flat packs were out there in case I wanted to go a different route and came across the Otica and servo subs which look to fall in the same 5-6K range (not counting finishing materials) so I’m mulling over switching things up a bit:
Current receiver: Denon InCommand X4200W – this is fine to drive the Otica’s correct?
I saw mention of a possible center channel in the forums for HT but nothing on the website. What would be an option here and is anyone currently using the Otica’s in HT setup? (I’m about 75% music 25% HT).
I assume the NX-Studio would work fine as surrounds but are there any other options that would work? Preferably a bit cheaper since they won’t get used a ton.
Space isn’t really a concern since I’m in the basement but I’m looking to do this once and be finished for a bit

Thanks in advance for the help and advice!
