Other sub amp for Gallo Ref3 secondary voice coil?

Spurzheim:

What kind of tube amp are you using? I am going to play with my SET amp when it arrives, but don't know if 7 watts will be enough...

I'll be using it with the Gallo SA amp --I'm signed up for one as soon as they arrive from my dealer (supposedly, they're on the water and due in soon).

With the SA, I'll have 3 amps to play with:
MacCormack DNA 0.5 Platinum (from SMC audio)
Dared VP 300B SET
SA

I have seen people use other Xovers and/or low pass filters and all have had success.

Hi Bgrazman - thanks for the response. I am using an Onix / Melody SP3, which is 38 WPC. It can shake the walls, but knowing that I can get another 10 Hz of extension makes me want to try a secondary solid state amplifier.

Do you mind me asking where you have seen others use filters/crossovers? I did some searching before the initial post, but came up with nothing.

Cheers!

I used 2 spare channels on a multichannel amp and used an Outlaw Audio ICBM cross over set to 40hz. It worked fine.

I gave up waiting for the Gallo amp and ordered a Hsu 500A (500w) subwoofer
amp with a 43 Hz crossover module. I had a 30-day moneyback period to
decide, and really like the thing. It's a SERIOUS amp and an ideal match for the
Ref 3s, which I'm driving with 12 wpc SET monoblocks (845 output tubes). The
500A costs $749 direct from Hsu, approx. $200 less than the Gallo sub amp.

Originally, I was using a Fosgate Audionics 100wpc amp with a Hsu electronic
crossover on the second voice coils, but this setup didn't have nearly the
authority of the 500-watter. Good luck, Dave

PS You need to break in those second voice coils just like the rest of the
speakers . Play 'em loud and hard.

Spurz,

I can't find the threads, but I'm sure it was here.

I'll keep looking

Dopogue,

How hard do you have to push your 845's? (the amp I have coming is based on the 300b tubes).

Thanks,
brent
