I'm currently looking for a budget sub to complete a 7.1, non-Atmos home theater and music listening setup (see below). I have 3 possible locations to place the subwoofer with different contingencies. The room is a 23'x12' living room with high (16'), sloped ceiling. My budget is below $300, I'm primarily looking for this sub to fill out the bottom below my RP280Fs during movies and am the type of music listener that often turns subs off for that purpose. However, I don't need it to hit earth-shaking low frequencies and space for each sub is limited but I would like it to blend in as well as possible for them money with my RP280Fs, especially if placed in the front stage.\n\nI've considered front firing subs like the Bic F12, PL-200 and PL-200ii and the $90 Monoprice 12" for the front right corner. Because... \na) I've got RP280Fs with pretty good low end in the front \nb) that corner is likely going to cause problems (boominess) and no room to breathe and \nc) because I prefer quicker, tighter bass\n\nI'm also considering sealed and\/or 10" front firing options (PSW 10?), but don't know which budget ones are sufficient for this size room and with the MLP basically 20' away on the other side. \n\nWhich led me to options 2 and 2a: What if I could bring the sub to the other side of the room, behind the MLP (2) or one side of that couch (2a), respectively? - I've read some pretty positive posts on that from people who actually did it (as opposed to theoretical hearsay) but in that scenario, neither mentioned 12" option will work because they're too big. Also, I believe a down-firing sub would be a better fit in these locations and I am thinking about flipping the phase to avoid issue with with my 280s firing in the opposite direction.\n\nThe questions:\n\n- Is one of the scenarios clearly superior over the other (given the restrictions and room size mentioned)? And if so why? \n- If a front position has clear advantages, what sub would blend well with the Klipschs?\n- For 2 & 2a, who has experience with smaller front firing subs behind a couch and wedged against a wall or on the side of the couch and perhaps even with down-firing alternatives in the same scenarios for comparison?\n- What decent <=$300 down-firing sub options are out there? The Bic V1220 would fit but I've seen videos and reviews talking about how it actually only has 100W RMS (even thought it says 160W on the amp plate to the left)\n- Lastly, how well would a front firing sub flipped to fire down, with feet to elevate it - work? Has anyone tried that? \n\nFor context, here's the rest of the setup:\n\nReceiver: Denon AVRX3500H \nFL\/FR: Klipsch RP-280F \nCenter: Klipsch RP-440c\nSide surrounds: RP-150M\nRear surrounds: Micca Covo-S \n\nThanks in advance for any insight!
