Vandersteen 5A Sub Amp

supermatt · 19th April 2003, 06:20 AM

This is a quote in regards to the new sub amp in the Vandersteen 5A.

"The new digital supply refreshes about 100,000 times per second and is fully regulated, so the voltage is always there. The result is much more stable and consistent power delivery to the woofer and you can tell right away when you listen to the 5A. The bass is even more controlled and yet effortless at the same time. As a matter of fact, the entire presentation from top to bottom can be best summed up by the word effortless.

Is this a PWM supply? Would it be worth implementing such an amp in a sub? If so, how would I do it? Thanks!

Does anyone know anything about PWM power supplies. I think it sounds like an efficient way to make a sub amp. Thanks

drive down to the local store and listen to any of the sub amps in the car audio area. They all must use some sort of switching supply, a great number of them just what you are talking about. Now, would you want that RF field right next to your other stuff? (early radio transmissions were made with similar concept. )Not a DIY project for sure, unless you have significant skills and the equipment to test it.
