New member Username: Dies_iraePost Number: 8 Registered: Oct-07 | I just picked up the carbon fiber (CF) model of the z5000 series cadence monoblock amps. It produces 750RMS@2ohm, but only 25@4ohm, Why is this? This really limits my choices in dual sub setups, unless someone can tell me a method of making say, two dual voice coil 4ohm subs into 2ohm. Etc... Anyone know much about this amp? Is it good? I've only let it push a p3d412, it rocked it - but I'm looking for a dual 12 setup, or some other setup that produces more SPL. (In the market for buying right now if anyone has anything). -750 WATT - HIGH CURRENT - 2 OHM STABLE - MONO BLOCK AMPLIFIER - 4 Channel Z5000 Specifications: ADR High Speed Mosfet Power Supply. "ARVA" Automatic Rail Voltage Adjustment Circuit. High Current Copper Rail PCB Arch. Studio Grade High Voltage Bipolar Output Stage. Mute & Delay Soft Start System. Balanced Line RCA Input. Pre-Amp RCA Line Output induction fan cooling X-Over Circuitry: 18db Per Octave Slope Butterworth Low Pass X- Over: Fully Adjustable Bass Equalization Circuit With Adjustable Center Frequency & Boost. 2 Ohm Mono Stable Gold Plated RCA Jacks, 8G Speaker Terminals & 2G Power/Ground Connections. Direct Connect Stiffening Capacitor Connection. F/R: 10hz - 40KHz Minimum THD: <0.044% S/N ratio: >100dB Channel Separation: >65dB Damping Factor: >200 @ 100 Hz Gain Control: 9v - 200mV Bass Drive: 0 - 16db Boost Freq.: 30 - 100 hz Crossover Freq.: 50 - 250 hz Subsonic Adjustable Filter: 10 - 30 hz Line Out: LPF, Full, HPF Crossover: LPF, Full, HPF Dimension: 10.8" W X 16.9" L X 3.1" H |

New member Username: Dies_iraePost Number: 10 Registered: Oct-07 | Yeah,I know - but every source I see says this amp only puts out 25-75RMS @ 4 ohm, and is only effective in 2ohm mode, at which it puts out 750 ( I can confirm the 750 rms@2ohm, as it beat the living hell out of my p3d412. |

Gold Member Username: Nd4spd18Northwest PA Post Number: 3354 Registered: Jul-06 | That is correct...... most cadence amps are that way, they only produce any meaningful amount of power at their lowest ohm load. So, you need 2 DVC 2 ohm subs, or 2 SVC 4 ohm subs to use with that amp. |

Bronze Member Username: Dies_iraePost Number: 12 Registered: Oct-07 | Okay =) That's fine, was just curious. It's a really nice amp from what I can tell (For my budget anyway, I know you guys have a lot more spare money and can build more impressive systems, but for me, this is nice - and I'm happy with it) I'll find some speaker configuration that works out well for me =) I was told in the subwoofer forum that for this amp, the highest SPL budget sub I'm going to find is an L7, so perhaps I'll go with that! |
