deepbass5 Posted January 21, 2012 Share Posted January 21, 2012 (edited) I have a set of Peavey Hi-sis 1's (12" tops) 4 ohm. and two 15" BW hi-sis bass bins 4ohm with poles. passive system If you are not familiar your amp would see 4 ohms a side, you plug into the bass bins where the internal cross over is linked to the tops, from memory they cross over at 180 Hz. These are old now but in good working order, tops only used vocals, larger venues we added bins for guitar bass and drums. sorry for delay in posting pictures but just got these back from my local music shop who over priced them. [size=5]£250 all in[/size] Edited January 26, 2013 by deepbass5 Link to comment Share on other sites More sharing options...

This would present each side of the amp reading 2x4 ohm cabs equals a 2 ohm load.best to check as many PA amps will not go down to 2 ohms per side.

[/quote] No - To put it simply-- The crossover in the bass bin keeps the lower frequencies, and sends the higher frequencies to the Hisis speakers, so still a 4 ohm load for the amp Link to comment Share on other sites More sharing options...
deepbass5 Posted January 23, 2012 Author Share Posted January 23, 2012 2x18 has it, the crossover only allows the amp to see 4 ohms at any time. Link to comment Share on other sites More sharing options...
mybass Posted January 26, 2012 Share Posted January 26, 2012 [quote name='deepbass5' timestamp='1327337132' post='1509553'] 2x18 has it, the crossover only allows the amp to see 4 ohms at any time. [/quote] Apologies as I'm not trying to interrupt the sale ( a very good price too for these). My understanding is that a crossover does not have anything to do with ohms, it simply 'filters' off the high end of the signal to another speaker so your bass bin cab ohm is still read as 4 ohms. (Why does it have an ohm rating in the first place?) The Hysis top cab is then also read as 4 ohms yes? This equals a 2 ohm load to any amplifier. Some Peavey power amps will go as low as 2 ohms but many amps only go to 4 ohms so care is needed. Link to comment Share on other sites More sharing options...

Truckstop Posted October 7, 2012 Share Posted October 7, 2012 Hello. Hate to ask, but want to be sure; so I'd need a power amp at 2ohms each side? Cheers Alex Link to comment Share on other sites More sharing options...
essexbasscat Posted October 7, 2012 Share Posted October 7, 2012 Couldn't have this for reasons of my own. That said, deepbass5 was great through all the conversations and patient with me while I sorted things out. Good guy to deal with Thanks DB Link to comment Share on other sites More sharing options...

deepbass5 Posted October 7, 2012 Author Share Posted October 7, 2012 That’s correct The Peavey X over works so the amp sees 4 Ohms per side. These have never been punished by a death metal band, had these from new, Function band gigs only mostly just the Tops for vocal only and occasional bins as well for big gigs.
