@backwash .... I’ll try some lane-splitting from by mcycle daze (legal in CA, not so much elsewhere) and advise within your budget.... ;)
Try the existing Tyler’s in the new space and let your ears get used to it.
Didn’t notice a mention of which wall is ’stage’ v behind, so start with the basic layouts. No mention of the floor type or surface; if ’vanilla’ (hard, no carpet) get some sliders to nudge the towers about.
Since you’ve existing traps and such, give ’em a go and mess about with the spl meter and ears. The price so far is just labor and listening....👍
@mapman suggested DSP, of which I’ve applied in ghastly spaces to decent results with the less than stellar sort of gear. You’ve a leg up if you’ve a ’puter in the closet that can be uploaded with some of the freeware DSP or the Parts Express ware and mic. A calibrated mic with a tripod beats having the spouse tolerating standing about getting tortured with test tones... ;)
The above will help in dialing your subs, which a pair could easily load the room beyond rationality.....
Buy a nice carpet and a backing for it. Assuming you’ve already have some suitable seating; perhaps the carpet as well.
If up for surround, match the tall Tylers with a smaller pair later when the muse moves you there....
Any new space should be an adventure and an opportunity to dig out the ’faves’ for a revisit to what sounded great before. Y’all are going to stay put for awhile, so rushing into the process can dissolve into a unnecessary PIA.
Enjoy yourselves....pour some wine or whatever floats the boat for the 2 of you.
It’s supposed to be fun, so have some. 👍😎
Happy trials, J
( PS: I’ve got similar in my future and that’s my approach in the nutshell... ;) )
