Thanks, I understand what everyone is trying to say, but what i don't understand is what the difference is between a top end sub and multiple low end subs. If i bought 4 of these subs, they should be better than the 15 in terms of bass, yes it may not be as accurate, but its still cheaper and would be almost double is bass. It's not like I'd ever run subs at max anyways, but i like the bass when the gain is about half way. So 3-4 subs at half way would be a great increase.
I'm just trying to understand how a one 15" sub can be better than 4 12" subs at 300rms each. Unless that 15" is a 2000w rms sub i don't see it being better. Can someone please explain to me what makes it better?
Again i'm used to car audio and with car audio, its not always about 1 good sub, but multiple cheap subs can be just as powerful. It just was a preference for 1 good sub depending on the cars size available. I hope i'm not coming off as argumentative. I just want to understand why paying $1400 for a 15" sub is better than $800 ($600 more since i have one) for 4 12"s instead. Technically i only need 2 more 12's. I have another psw505 in my room that i could move to the living room if i wanted making the sub upgrade $400 instead of $1400.
I'm all for quality, but if my current sub sounds great to me for quality then why should i upgrade. My only complaint is that the bass is a little weak, but that can be fixed by adding more.
Buying two of something of lesser quality doesn't automatically mean it will equal one of something that's already excellent by design.
The Polk's are not built with high quality drivers with massive voice coils and spiders, extremely well reinforced cabinet bracing, thick walled cabinets, and robust digital servo amps (to control driver excursion). They're built to be budget subs for, well, budget conscious customers. There's a reason they sound weak and it's in the parts they're using.
Not to sound snobbish, but the FV15HP is like an Audi sports car by comparison... all the parts are of quality and the frequency response sweeps are impressive. At the lowest tactile frequencies (below 20 Hz), you're still getting quite a bit of oomph, whereas the Polk will die off in the upper 30 Hz range... not good for movies. It's far more accurate in the recreation of the frequencies it's designed to produce. More musical, and tight. The hit and decay of the notes are very fast and not flabby or bloated. During heavy bass passages, the sound is practically effortless and doesn't sound strained with minimal port noise. An explosion will sock you in the chest with visceral energy. Movies and music would sound more like being in a commercial cinema, which is the idea behind home theater systems.
The larger Rythmik will handle about as well as a couple, smaller 12" subs in sheer audio output. We're mainly just saying that if you can't afford the hit of one big, somewhat expensive sub all at once, getting a couple smaller, less expensive 12" subs (like the ones mentioned) over time would work about the same in volume output. If you're looking to tame room acoustic peaks and nulls, then multiple subs will help give you an more even spread of sound.
It all depends on your wants and needs. User Axxiom got Ascend speakers and a 15" Rythmik sub in a smaller apartment (like putting a bull in a china shop) and is loving every minute of it. He's even considering getting a second
Rythmik for the purpose of smoothing out the room response... the depth of bass is already impressive.
