Hifonics ZD-3350.1D Zeus Delta Amplifier vs Hifonics Zeus ZXX-2400.1D Monoblock Amp

Buy the Zeus Delta ZD-3350.1D if you run one or more subwoofers that can take real power and you have the electrical system to feed it. Buy the Zeus ZXX-2400.1D if you want a simpler, lower-draw install driving a single moderate sub. The Delta is the bigger, more capable amp: more power at every impedance, a wider subsonic range, a 2 AWG terminal, and a bass remote in the box. The ZXX is the more modest design, with a 650 W RMS rating, 95 dB signal-to-noise, hex screw terminals and preamp outputs. Both are Class D Hifonics monoblocks with the same Simpatico dual-coil power supply approach, so the real split is power headroom and install demands, not brand or topology.

  • Choose the Zeus Delta ZD-3350.1D if your subwoofer setup can absorb well over a thousand watts and your charging system can supply the current a 2 AWG feed implies.
  • Choose the Zeus ZXX-2400.1D if you are powering a single sub at moderate levels and want preamp outputs and hex screw terminals without a high-current wiring upgrade.

  • ValuePraisedBuyers call it a lot of subwoofer power for the price.

Questions and answers

Which is better for a single subwoofer?
The ZXX-2400.1D is the better match for one moderate sub, since its 650 W RMS rating suits a single driver without a wiring upgrade. The Delta only pays off if your sub is rated for well over a thousand watts.
Which handles multiple subwoofers better?
The Delta. Its 3350 W at 1 ohm and 1675 W at 2 ohms are built for multi-woofer loads, and its 2 AWG terminals support the current that takes.
Does the Delta have preamp outputs?
None are listed. The ZXX-2400.1D lists RCA preamp outputs, so it is the easier one to daisy-chain into a second amp.
Which has better sub protection?
The Delta, because it has a variable subsonic filter from 15Hz to 40Hz. No subsonic filter is listed for the ZXX.
Is the Delta worth stepping up to?
Only if your subs and electrical system can use the extra power. Otherwise the ZXX's lower draw and preamp outputs make it the simpler install.
Do both include a bass remote?
Yes. The Delta ships with a wired bass remote, and the ZXX includes a bass knob and remote.
