derrickdj1 Posted July 29, 2013 Share Posted July 29, 2013 I wish I knew how to ask this question in a more informative way but, I don't have much knowledge about this subject. I have 2 Chase SS 18.1 passive sealed subs on a Berhinger I Nuke 3000 DSP amp in bridge mode. What should the limiters be set at? The subs power ratings are 800/1600 RMS/peak. The amp is seeing a 4 ohm load and the power rating is 1520/3000 watts at 8 and 4 ohm bridge mono. In the DSP I can plug in the ohm load of 4 or 8 and have an attack and threshold control. The LPF is at 200 Hz with a 24 db slope and the HPF is off since the subs are sealed. Any guidance is greatly appreciated, thank. Quote Link to comment Share on other sites More sharing options...
Quiet_Hollow Posted July 30, 2013 Share Posted July 30, 2013 Hi Derrick, Where did you come up with 800?? All I could find for the SS 18.1 was 500W RMS @ 8 Ohms nominal. That's 63V. 800W would be 80V. I wouldn't recommend bridge mode. One cab per channel will work just fine. Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted July 30, 2013 Author Share Posted July 30, 2013 Here are the numbers from their site: done in our Pennsylvania Factory. SS-18.1 Subwoofer - SpecificationsType: Sealed, single driver, passive subwoofer system Frequency Response: 21Hz – 100Hz +/- 5 dB (Using the Dayton Amp and the bass boost switch is ON)In-room extension (room and placement dependent): 15Hz or lowerDriver: One 18”, 8 ohm driver X-Max (not X-mech) is 1.5 inches peak to peak Fs is 19.4 Hz Power handling is 800 watts RMS Enclosure: Sealed, passive, front-firing (no grille) 1" MDF 2" thick, MDF, front-firing baffle Countersunk driver Slightly textured, matte black finish Dimensions: 23" H x 21" W x 21" D Weight: ~75 lbs These are my current setting for the Limiters: db fs -0.5 vp 160.5 watts 3220 ohm 4 hold 200 ms release 400 ms I am running in bridge mode for the two sub and the amp should see a 4 ohm load. The subs are 8 ohm. Concern for the drivers arose when Craig sub from Chase said use limiter with no explanation. In stereo this amp delivers 440/820 watts at 8/4 ohms. The limiters should keep me safe??? Thanks! Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted August 1, 2013 Author Share Posted August 1, 2013 I heard back from Craigsub and it seems he thinks these setting are fine, so everything should be OK. Thanks for the help Tom! Quote Link to comment Share on other sites More sharing options...
