Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Intended as a simple circuit

This type of circuit does work to provide a simple single volume control subwoofer option, provided the sub amp has a decent (24db) crossover. I use a very complex 24db electronic crossover that I have put in a lot of time and money into. It sounds great, but this little circuit probably can get you 90% of the way there with compromises.

In terms of the input transformer, you will have to ask Jack, it would seem the 10K and the 100R are the reflected impedance. I assume the 100R is a tap, not certain how it is calculated/implemented here.
