Do you have a satellite playing full band? as far as I know, the 8003 has an HPF output for a satellite, or is it not necessary to trim the satellites for this subwoofer?
Not a snowball's chance in hell the new 8003s will keep up with the 915s at full volume. You'd need at least a pair per 915, if not four per 915. The 8004s wouldn't either. Every octave you go up requires only 25% of the power applied to the lower octave to make the higher octave sound as loud. Thus, every octave you go down requires 400% of the power applied to the higher octave to make the lower octave sound as loud. However, I bet they sound pretty good at nominal levels. I'm thinking of getting a couple and running the under my old RCF ART 522 cabinets.
@@johngembka7052 I read on many reviews that rcf is weak across its entire subs world. (Except tour grade ones). So I think a better option would be going with FBT or other brands
@@francescog53550 RCF subs are fantastic. It's just that many people don't understand that adding a 2200 watt sub under a 2100 watt top cabinet isn't going to bring the magic results desired.
@@johngembka7052 2200… 2100… 1050… What if told you that RCF ART 915 are actually, real world continuous power, less than 400 W RMS? Because believe me, I’m Italian, same as RCF, and this is the actual power of that amp. Not more. If anything, less.
@@francescog53550 I have been using RCF gear for maybe 16 years now, longer if you count the "Italian Mackie" SRM-450 cabinets that came out in the 1990s. I love their gear. I have had RCF subs, ART 322, ART 522, and ART 745 MK4 cabinets, and now I may upgrade to the NX Series. They previously posted the RMS / Peak ratings, but now they show only peak ratings for newer gear. The 915 is bi-amped, so there are two amps inside. The amp for the high frequencies is rated at 700 watts peak and 1400 watts peak for the lows, so I'd expect 350 RMS for the highs and 700 RMS for the lows, or in that area. So what you're telling me isn't really a surprise. It's also worth noting that RCF frequency ratings are +/- 3 DB. I don't think RCF is remotely close to pushing misleading specs as many other manufacturers do. QSC is among the leaders of misleading specs. Instead of a 500 watt RMS, 1000 watt peak amp for the lows and a 250 watt RMS, 500 watt peak amp for the highs, they just put two 500 watt amps in their cabinets and tell you it's a 2000 watt cabinet. You'd blow apart the high frequency section with a 500 watt RMS, 1000 watt peak amp, so they have limiters in place to limit the output of the high frequency amp. RCF cabinet ratings tell you what actually comes out of the drivers. QSC ratings tell you what the amps are capable of delivering rather than what actually comes out of the drivers. FBT makes good stuff, but read the specs. I just pulled up one of their subwoofers - a Horizon VHA 118.2SA. Frequency response says 30 Hz - 100 Hz, but it is +/- 6DB rather than +/- 3DB. This means the 30 Hz signal is there, but you'll never hear it or feel it. That sub is probably more like 45 Hz - 90 Hz at a +/- 3DB rating. Maybe. And it's that way across the entire FBT line. Don't get me wrong - I love RCF, and I like FBT and DB Technologies very much. It's just that RCF is my favorite among the Italian manufacturers. And I'd take any of them before something made in a certain communist controlled country to the east of Italy!.
