I found these specs online (www.cheaplights.com). They are for a 15" Speaker that is selling for $155.85. I'm pretty sure it is an off brand (speakermax?). Are these worth looking into or should I go with a more reputable company like JBL? SpeakerMax Full range speaker. One 15 inch woofer with 90 oz magnet, 5x15 horn with titanium compression driver. 500 watts continuous, 1000 watts peak. 8 ohms. Frequency response 45 to 20k Hz. Sensitivity [email protected]/1m. Two 1/4 inch jacks and push terminals. Metal corners. SIZE (HxWxL)- 28.25x18.5x13.25, WEIGHT- 57, COVERING-Black carpet. For safe shipping, this unit comes without the woofer installed. A phillips screwdriver and a few minutes will have the job done.
