[QUOTE="TJ Cornish, post: 58927, member: 162"] Re: Subwoofer comparison SRX728 vs Vertec 4883 Someone at JBL must be listening, as in the last day or two they added the response graph to the 4883 spec sheet. This wasn't there as of Sunday. Here are the graphs: [ATTACH=CONFIG]150681.vB5-legacyid=4469[/ATTACH] As Ivan expected, this is a "processed" graph. Poking around in LAC this morning reveals the following: Using the "DSP SPL" option, single speaker, 1 meter [TABLE="width: 500"] [TR] [TD]Subwoofer[/TD] [TD]31Hz[/TD] [TD]40Hz[/TD] [TD]50Hz[/TD] [/TR] [TR] [TD]4882 (larger - dual 15" est 13.3cu ft)[/TD] [TD]119.3dB[/TD] [TD]127.8dB[/TD] [TD]127.3dB[/TD] [/TR] [TR] [TD]4883 (little guy - dual 12" 5.25cu ft)[/TD] [TD]112.8dB[/TD] [TD]120.3dB[/TD] [TD]125.8dB[/TD] [/TR] [TR] [TD]4881 (single 18" 10.4cu ft)[/TD] [TD]110.3dB[/TD] [TD]116.3dB[/TD] [TD]117.8dB[/TD] [/TR] [/TABLE] [/QUOTE]
