Sage advice there, settle on competent mains, and pursue optimization efforts within the interface (the speaker/room interface, ie, placement, adjustment, acoustic treatment).
I recently began going back and reviewing the GTG thread, it moved so fast, much vitally important takeaway info was missed, I'm going to add a follow up.
Regarding JTR gear selection on a budget, etc, heres one perspective;
Starting from scratch, if I had a modest limited budget, and wanted a 5.1 JTR platformed HT system, I'd go for a pair of single 8s, and a quality sub or two that would be the first component(s) to a first rate multi-sub system. I'd employ two individual amp channels with some way of manipulating time delays and slopes (Inuke DSP, or miniDSP), as this is key for ideal blending. I'd also include budget for some simple room treatments, bass traps in the corners as big as aesthetically acceptable, and a single 6" or 8" treatment panel per sidewall, and a pair of 4" ceiling cloud panels spaced off the ceiling another 4".
This ^ would be a nice start, with leverage on performance via acoustics, ... and one could fill in the remaining components as funds allow. I base this on subjective impact
, solid LF performance is monumentally huge subjectively, thus much initial effort is placed there ... both gear and acoustics/treatment.
Eventually move the single 8"s to surround duty, and elevate mains performance with Noesis or equivalent. The DIYsoundgroup is a great source for subs, as is PartsExpress with assemble it yourself cabinets, drivers.
Important, some simple measuring gear and the basics of how to use it. Then make all changes via acoustic need.
I think subs are such a big part of the subjective picture, single 8s and a powerful but well executed sub system with focus on acoustics is key, IMO
Best of luck
