Can we start a thread for folks who run a SET amp with a subwoofer or two?


I moved down a pathway that was an offshoot from the mainstream of this hobby-a single end triode 300b amp.  So what I got with a SET was more than I gave up.  But bass lacking can be tough to live with. A brought in a couple of subs that took CONSIDERABLE tuning experiments, measurements, and ultimately following my ear.  

Who has experimented or uses a subwoofer or sub bass condiment with a low powered SET amp?

@jbhiller, 

You have a very nice system. Thanks for sharing! 


IMO, no tube amp or speaker can come close to pressurize a room with low bass the way a subwoofer is capable of.
I have a set of Classic Audio Loudspeakers model T-3s. They employ two 15" woofers, one of which has a 22Hz free air resonance. They have no problems pressurizing a room with low bass without a sub. System efficiency is 98db and impedance is 16 ohms.

And they are powered by? Amp specs please? 
I built Bottlehead 2A3's, Madisound BK-16's with Fostex drivers, super tweeters and added a Mirage SA-8 sub.  The sub makes it a party system.  Just add beer.

I run them with an Atma-Sphere S-30 (a triode OTL with only one stage of gain) which can make about 45 watts into 16 ohms. The S-30 is full power to 2Hz so I run it full range on the T-3s. It literally can shake the house :)
