From what I’ve heard, you’re better off with room treatment than nice monitors. I’m a total pleb in this regard though.
Yeah, I do. I have three of them, and three HTMs but only 5 tweeters, and only 4 tweeter housings. It's a whole thing, but trying to get a complete pair of 805's for not a lot of money involved a bigger initial investment in more speakers, to piece things together. And with the difference in both availability and street price, it makes sense to sell the 805's as a complete pair, to fund other things...like room treatment.

RE: A/Bing, I've done a little, but not with a clean enough setup to make it a useful exercise in answering my original question, but I can't hear a difference between the two models, hence my leaning toward the HTMs as they are the more affordable equally functional option.

The question was about the asymmetry of the ports on the two speakers and whether that will significantly effect the stereo image. I haven't studied up on the intricacies of speaker port design and whatnot, so I figured maybe someone here might have some valuable thoughts.

What I'm getting is that I'm overthinking this and getting ahead of myself.

HIs schtick is just getting extremely tiresome. Posting pages and pages that rarely even get close to the subject at hand is annoying at the very least. I'm not sure what he is trying to prove but he needs to take a nap. I was probably being a bit rude. Sorry for being rude. Guy just gets my hackles up.

The port location should not be relevant to the 'imaging' or perceived performance of the loudspeaker system. In fact, if properly designed, there should be very little audio information emitted from the port. In small enclosure desktop/nearfield monitors, the port mainly exists to balance the natural first order resonance of the LF driver with the smaller volume of the enclosure, control that resonance and extend the LF range below the resonant frequency.

A front-facing port isn't so much a concern when discussing loading of the cabinet against a back or side wall, through loading will still occur if you're placing the cabinets on a desktop or flat surface. You can tune this out, if needed, and start with the basic math +6dB increase for each loading surface from free-field, or mount your monitors to the wall on arms or use stands (though if you're using wall mounts, now you need to be concerned with the acoustical issues of energizing the wall materials and transmission of audio to adjacent spaces).

FMBD isn't necessarily wrong about the stuff he wrote about subs and speaker positioning, if you're looking for more fundamental background regarding those things. However, my answer assumes you're not dealing with subs here and your full range system run flat doesn't do much below maybe 45-55 Hz.

Thanks for this. These speakers are rated down to 48Hz, I believe, and pretty flat. I'll likely forgo a sub altogether, at least for now. I do intend to put them on stands, which will sit behind a mixing console, and likely near a wall, if not in corners, given the tight constraints of the room. Again, the room is not completely set up yet, nor has it been treated, but that is part of the plan.
