Gallo Nucleus Reference II

Hey aheadstereo: I have a Pair of Gallo Nucleus Reference I (has the polypropelene balls instead of the spun aluminum ones). Currently in storage.

On my model, they can be wired either in parallel or series, and in each of those in either mono- or biwire configuration. Per the owner's manual, when wired in parallel, the speaker system impedance is 2 ohms, and the efficiency rating is 91 db. Hooked up in series, the impedance is 8 ohms, but the efficiency drops to 88 db. Either way, they are rated to handle up to 300 watts.

So the hookup depends on what your amp is. I will try to post some shots of the wiring scheme from the manual. 
 

Obviously, for the 2 ohm parallel hook-up configuration, you need a SS amp with some high current capability, most tubes won't cut it. Also, the bass can tend towords the loose/flabby side, so an amp with a high damping factor would be a plus to show these off at their best. 
 

 

I think the wiring should be the same for the Ref II model. You may want to write to Gallo Acoustics and double check. They may be able to help, they are still in business, although these speakers are from 1995 or so.

Hoping someone can help with the hookup.  We just received a pair for trade-in.  There are 2 posts and then 3 under that (in addition to the 2 on the woofer).  We have a filter as well.  What goes to what?

Maybe a picture would help!

Hello there

Late to the conversation but even though I am not sure what you were asking (just like frostdotcom above), I had the EXACT SAME experience as you did. I was going to try to remove a dent on my Nucleus Ref II's so I disconnected them and replaced my system with a pair of the Omnisat's and the Omni s-10 sub and was AMAZED at how good they sounded - I honestly believe they sounded as good as my Gallo's alone! So much so that I am considering replacing the Gallo's with a pair of Mirage OS3 - FS Tower Speakers (same tweeter section as the Omnisats with a beefier bottom end)

Just FYI

Ciao,

Yes the Gallo Reference 3.1 is an excellent speaker and cool looking to boot.

I sent mail, thank you 192168101.com

im not sure what youre asking or saying but the gallo reference were absolutely fantastic speakers.  the biggest downside being that if the tweeter dies theres no way to replace it.  I have a pair of gallos and they are just fabulous.

Hi, that interesting! I would be curious to see the Gallo speakers, can you send me some images, thank you very much! email: 1@c-jm.com

Tough call.  I’ve not had any gallos, yet, but have always had my eye on them.  Im also not familiar with the line up bug I googled your speakers and they look pretty sweet.  They also are very unique in their design.  Im not sure I’d part with those speakers.  
If you are feeling the desire to change things up a bit, perhaps you should go a different route.
