Also, thanks in advance for any help!
Okay, in that case I think I'm going to have my plan be 2 F15HPs then.
If I go for something like a F25 which is dual 15 sealed, wouldn't I still have the same problems as going for a single sub? My understanding was that you want two subs to even out the peaks in the room, and make it harder to locate the sub, and to do that you want to spread the subs a decent bit from each other. If you just had the two subs directly on top of each other you'd get more output, but you wouldn't fix the other problems. If that's not true then I might get the F25 since that's much cheaper than two F15HPs
The 4 year horizon is just because I have a lot of student debt to pay down, and paying it down as fast as I can will take about 3 years, then I have one year to save money and move out. So after 4 years I'm free to spend lots of money on speakers again
The biggest question is Do you need to have even bass across your whole room?1.) I generally know that having multiple subs is better, because it evens base across your room. I assume this benefit increases with 3 or more subs, but is it significant compared to just 2 subs?
One argument for a single larger unit is futureproofing, it sometimes works out better to buy one now and add another later for a future larger room instead of cobbling together 4-5 smaller units or starting over. That's why I was asking about the 4 year time period. But that's kind of a wildcard anyway.
So maybe the compromise to both of these is that I should purchase a single F25? It gives me more future proofing than a single F15HP, let's me see if I need dual, and if in the future some magic happens with audio I could safely move the F25s from my bedroom and place them in the HT room with no lost value.The biggest question is Do you need to have even bass across your whole room?
I would not worry about multiple subs unless you have more than a couple of main listening positions. Even then, the odds may be that you will have adequate bass in most areas.
The important distance is each locations proximity to peaks and nulls.As a question though, how much does bass response generally change throughout the room? The two main listening positions would be on my chair in front of the desk, and then on my bed ~7 ft directly back from that position, so both main listening positions are still pretty close to each other.
