That's right. Dennis (DJK) and John (str8aro) and I have discussed push-pull systems in the past. John has made measurements that confirm the reduction of second harmonics using this configuration. About the cooling duct, I'm with you on that. It seems like motorheads are the first to embrace the idea. I was thinking of car stuff too when I first pictured ducting the vents. Thomas (ToFo) has proposed a dual-port anti-reversion venting system to prevent a warm air slug from travelling back and forth in the cooling duct. It has a cool air input line and a warm air exit line, each with an AR orifice to polarize flow in the proper direction. That or do something to conduct heat away within a single duct and dissipate it along the way. Perhaps introduce turbulence to get the air in contact with a large, cool surface area.
