Swingcats 0 Posted January 2, 2008 Report Share Posted January 2, 2008 I have an old pair of Peavey HiSys speakers which I am swapping with a forum member, is it possible one is 4 ohm and one is 8ohm, they look identical, plates on back hard to read, I used them for two years though a soundlab 800 watt amp and no problems. Will it cause problems if they are different? Good Rockin Daddy (Chris) www.swingcats.co.uk Music to dance to from 1930's to NOW! Shake your rude box.

UKHero 0 Posted January 2, 2008 Report Share Posted January 2, 2008 I also have two hisys speakers are they the old wooden trapazoidal type 12" Woffer and a horn?? If so I think they should both be 4 Ohm as they were designed to be used with the bass unit and if you use them on there own for a disco the LF can damage the 12" drivers. Hope this helps in some way Nik Niks Roadshow Link to post Share on other sites

rictic 0 Posted January 2, 2008 Report Share Posted January 2, 2008 on these cabs it says hisys 2xt on each and they are identical apart from one has 2 speakon connectors and the other only has one. inside behind the right hand handle is a switchable socket on the crossover for either full or dedicated subs. they are both set fpr full range. but one driver has a label saying black widow 4 0hm the other says 8 0hm. would an unbalanced load from the amp do any damage and would the 2 sides have a volume disparity with one being 4 ohm and one 8 ohm? it is a tad confusing and a bit scary to fire them up and give them some welly if the amp may go bang. also i have been informed by a peavy agent that it might not just be a case of swapping a driver as the crossover may be set to a different frequency on a 4 ohm than an 8 ohm. not definitely but possibly altho they look the same. end our confusion. <a href="http://www.djassociates.org"><img src="http://www.djassociates.org/anims/compres_banner.gif" alt="Join the DJ Associates Disc Jockey Association" border="0" width="468" height="60"></a> Link to post Share on other sites
Swingcats 0 Posted January 2, 2008 Author Report Share Posted January 2, 2008 As you can see I already sent them to Dave. I never took the things apart so never saw the 4 and 8 labels.

superstardeejay 0 Posted January 2, 2008 Report Share Posted January 2, 2008 Yes, Peavey do them in both impedances and yes there'll be a major difference between the sound if they're used as left and right on the same system. If they're used with a two-way crossover in bass bins then they wont cross over properly if the bass bins are identical. The amplifier wont mind with a lop-sided load so long as both loads are within the amp specs. Never come across this one before!! . Link to post Share on other sites
Swingcats 0 Posted January 3, 2008 Author Report Share Posted January 3, 2008 Typical, This kind of thing always happens to me!!!!! I guess when you first start out without the added bonus of being a forum member you can end up buying a pup. Let me know if you can use them Dave and we will go from there.

Will it cause problems if they are different? I have used peavey speakers i use hysis 2s hysis 4s 215 subs 118 subs with peavey pv2000 amps the crosover is built in to the amp and i can honestly say they sound great and i have found them very reliable i got some unusual hysis 2s today they have a vocal socket on the back and a normal input socket with a swithed flat /eq im going to have to look up what differance this makes if any Link to post Share on other sites
supersound dj 0 Posted April 16, 2008 Report Share Posted April 16, 2008 Run the 8 ohm side in series with 1 sub ...that should bring that side down to 4 ohms ..use a 8 ohm sub too. Link to post Share on other sites
