[QUOTE="Warbleed, post: 694617, member: 549898"] The 500w power rating is pretty conservative for the RL-p. It uses a 2.3" long 4 layer 3" diameter VC, so it's thermal powerhandling is honestly going to be just as good as the XXX's. 1 watt efficiency of the drivers is pretty close. The XXX does have the advantage for maximum linear output, but admittedly would require more power to reach that point. The RL-p isn't going to be at xmax in that box until you dip well below 20Hz. The XXX is actually going to be at pretty similar excursion levels, it just has more excursion left to give. Technically, the XXX should have slightly better extension, since it has a higher Qes and higher Mms, and consequently, a lower F3 for any given alignment. People also tend to grossly overestimate the mechanical powerhandling of the XXX in many enclosures. The XXX would hit xmax slightly below 25Hz in that box if you gave it a full 1.5-1.6kW, so you can't just keep piling on power and expect to keep gaining, at least not below 30Hz. Lastly, remember, the XXX 12 only has about 18% more displacement than the RL-p, so it's only capable of about 1dB more linear output, at most. The XXX will have lower overall distortion throughout it's excursion range, but to say it will "kill" the RL-p in linear output is just blatantly false... [/QUOTE]
