Is the RCF SUB 8004-AS sufficient for a live band?
This system is sufficient for acoustic bands (solo artists, acoustic duos, small classical trios). For a 4-5 piece cover band with drums, electric bass, and electric guitar, it is worth adding an extra subwoofer for more bass impact or upgrading to a larger PA system. Feel free to contact us directly with your specific band setup.
What is the total wattage of the RCF SUB 8004-AS?
The complete system delivers approximately 2500 watts of RMS Class-D power. This allows you to reach around 134 dB SPL at full output, which is enough for a fully energized dance floor with heavy beats. At standard background levels, you will use at most 15-20% of the available power.
Can I set up the RCF SUB 8004-AS by myself, or do I need help?
With a bit of effort, you can set it up on your own, though having a second person to help carry the subwoofers (often 20+ kg) is highly recommended. For larger setups, we suggest booking a Renty staff member for delivery, setup, and teardown. This costs 59 euros per hour.
How do I connect a microphone to the RCF SUB 8004-AS?
You should connect via a mixer: microphone → mixer (XLR input) → PA (XLR out from master). Connecting directly to the tops only works if the model has a mic input with a preamplifier (which is rare). For classic wedding speeches, we recommend a wireless microphone plus a 4-channel mixer as a complete set from Renty.
Do I need a DJ or a mixing console for the RCF SUB 8004-AS?
For pure background music using a playlist, a direct Bluetooth or AUX connection from your smartphone to the tops is sufficient. As soon as microphones, multiple sources, or a DJ are involved, we recommend using a 4-8 channel mixing console between the source and the PA. You can book suitable mixing consoles with Renty.
How heavy are the individual components of the RCF SUB 8004-AS?
The tops weigh between 15-25 kg each, and the subwoofers weigh 25-40 kg. For transport, they feature carrying handles and, in some cases, integrated wheels. A typical setup fits into a standard station wagon or van and can be assembled by two people in 20-30 minutes.
