Do you guys thinks I could use an Onkyo receiver with this speaker ? I am thinking about buying the magnepan MMG w and MMG C. Here are the specs of the receiver. Power Specifications Power Output* (8 ohm, 20 Hz-20 kHz, FTC) - Front L/R 65 W/Ch Center 65 W Surround L/R 65 W/Ch Surround Back - Dynamic Power** - 3 ohm (Front) 160 W/Ch 4 ohm (Front) 125 W/Ch 8 ohm (Front) 85 W/Ch Amplifier Design Identical Full-Bandwidth Channels 5 Reduced NFB (Negative Feedback) Design WRAT (Wide Range Amplifier Technology) Non-Scaling Configuration - DACs 96 kHz/24-Bit x 6 High Current Low Impedance Drive All Discrete Output Stage Amplifiers Optimum Gain Volume Circuitry Digital Upsampling Home Theater Features THX Surround EX and THX Certified - Extended Frequency Response (+ 1 dB, - 3 dB) 10 Hz-100 kHz DTS, DTS-ES Discrete/Matrix 6.1, DTS Neo:6 DTS Only Dolby Digital, Dolby Pro Logic II Dolby Digital EX - A-Form Listening Mode Memory - Composite and S-Video to Component Video Upconversion - Composite to S-Video Conversion - Multichannel Input 5.1 CinemaFILTER Digital Soundfield Processing Modes 9 Late Night Mode Color-Coded Speaker Terminals On-Screen Display - Adjustable Digital Delay Crossover Adjustment Internet Features Net-Tune - Ethernet - Number of Presets (Internet Radio) - Inputs Audio and AV Inputs 2/4 HDTV-Ready Component Video Input/Output - Front-Panel Video Input (with S-Video) S-Video Compatible Jacks Input/Output 4/2 Digital Inputs 2 Optical, 1 Coaxial Digital Output - Amp In - RS-232 Control Port - IR In/Out - Pre Outs Front L/R, Center - Surround L/R - Surround Back - Subwoofer Other Features Dot-Matrix Display Display Dimmer 3 Levels Pure Audio Mode - Dual Banana Plug Compatible Speaker Terminals Except Speaker B Sleep Timer (90 minutes; 10-min steps) Phono Input - Headphone Jack Zone 2 (Multisource) Line Out - Powered Zone 2 - 12 Volt Trigger - A/B Speaker Drive A and B
A wonderful speaker that does many things right with the main shortcomings to my mind being that they don't go very far down in the bass which might make integrating a sub a little problematic. If like other maggies, the loads are largely resistive (a good thing), that is a fairly constant 4 ohms but drops to around 3 or so in the upper frequency ranges. Further the efficiency is a relatively low 86 dB. I think your receiver will be sorely taxed in driving these to any reasonable levels without distress. You should be looking for a continuous power rating into 4 ohms of greater than 100 watts IMO which would suggest a far more substantial receiver or outboard amps.
