Monolith speakers with DIY enclosures for soffit mounted studio mains
March 16:
Alighty, I bit the bullet and bought a DATS machine and tested a single woofer. Below are the results. My results are outputting for a 2.5" ported box. Going to play around with the parameters soon but would like to hear any input from folks here!

I was able to get most of the parameters below supplementing the unknown with these 2 speakers:http://www.loudspeakerdatabase.com/VISATON/AL170-8
and

i think i have come to some sort of starting point for the enclosure build. The speaker seems "happiest" inside a 3sqft enclosure which will be a little challenging for my space but i can be creative.
Green is the ported version and the blue is sealed.

I managed to get some parameters from the impedance curve supplied by monoprice. Im not totally sure how accurate this curve is because it looks to be smoothed, however i gotta go with what i got!
Hi all!
I will be building out a new studio in the next month or 2, and I decided to pull the trigger on a pair of Monolith LCR speakers. At first I was considering building my own speaker but after going down a crossover network rabbit hole, I decided to pickup after the speaker design.

They have a pretty decent response, although (i think because of the THX) they do roll off around 100hz, making way for a subwoofer.. I'm hoping i can pull a little more bass with a ported enclosure and hack the crossover if there's a high pass somewhere in the woofer circuit. I will be back for help! The soffit mounting should bump up the bass too.
Anyway I thought I'd throw this out there in case anyone else is interested in building an enclosure with a decent set of speakers! They're at a pretty good bargain at $290 (less so on their ebay store)
Monoprice have been tight-lipped with their Thiele-Small Parameters- stating "I apologize but that information cannot be provided due to propriety." So my enclosure is going to be a "best guess"
(the numbers are going to change once the speakers and baffles arrive)
