[QUOTE="Art Welter, post: 116684, member: 52"] Re: System advantages/disadvantages Jonathan, A pair of DSL TH-118 can equal about four JBL SRX 728 (my TH using the same driver as the TH-118 does the same) but according to DSL's specs, at rated continuous power the TH-118 does around 136 dB at 100 Hz. A pair of TH-118 would do about 142 dB at 100 Hz, while one SM80 does about 118 dB at 100Hz, 24 dB less output. Even above 200 Hz (rather high for a tapped horn sub, or any sub on the floor) a pair of TH-118 would outrun the SM80 by 14 dB. Other than EDM and some Hip Hop, I seldom see any pop music recordings with LF peaks below 200 Hz exceeding the upper level by more than 6 dB. What SPL levels do you generally hit at FOH below 100 Hz and above 200 Hz? Art [/QUOTE]
