Anthony Gallo Ref 3 - Bass Solutions with Tube Amp

If you acquire an active crossover with level output controls you will not require output controls on the sub amplifier.

Hello,

I just bought a pair of these ref III's off audiogon last week. They are fantastic, and are getting better hourly.

My problem is I am running them with a digital panny xr25 receiver, and I am trying to figure out a way to power the second voice coil in an inexpensive way. I was planning on buying the new xr70 when it comes out, and using them both connected via a digtal output to power both voice coils of the ref III's.

The pannys do not have preouts. I cannot figure out how to send the second voice coil the 50 hertz and below signal. Is their a crossover or low pass filter that I could install between the panny and the speaker somehow, without using preouts? Those F-mods are cool, but I do not think they will work in this case.

I know that the gallo amp/crossover--when it comes out--will take the 0.1 sub output and use that, but that is not coming out until the end of the first quarter next year. Of course, the way things are going, the xr70 might not be out until then either!!

Anything on the market that I could use now?

Thanks ahead of time for all your help and time.

Here' another idea: Parts Express has DIY subwoofer kits. They have several amps. I'm planning to purchase the version with 200 watts. It has a level control, a variable low pass filter and continuous phase control. The crossover is a second order version and rolls off at 12 db per octave. They cost about $120 each. I'm planning on buying two, making a plywood box both to house them, and presto, a dual mono amp for the second voice coil. I ran my idea by a technical guy at Gallo. He said that asked Anthony about it, and he thought it would work fine.

Not as good as the Gallo amp I'm sure, but it's available now, and will cost $240 instead of $900 for the Gallo amp.

Does anyone have any reactions to this idea? BTW, Parts Express also has 500 watt amp for about $250.

Aloha Rich,

Curious if you tried your solution yet, and if it worked?

I haven't tried it yet. I'll probably order the amps this week though. I'll post my feedback.
