View Full Version : Gilderfluke sd25

Is anyone familiar with the Gilderfluke sd-25? Is the amp powerful enough for a loud haunt? I am so sick of cd players and I am not comfortable with the idea of centralizing all of my sound in a computer system

A "loud" haunt is a little to subjective but a class-D amp is going to be much more powerful than your average amp. When a class D is on on the power dissipation is very low. This increases the efficiency, thus requiring less power from the power supply and smaller heat sinks for the amplifier.

Like stated on their website a class-d amp that is 50 watts can out power a regular class AB 200 watt amp. Class-D amplifiers are often operated in a bridged configuration to increase the output power without increasing the power supply voltages.

Greg how much you looking to spend on centralizing your system, there are a variety of options in solid state playback besides the SD25. Tell me what you are looking to do, number of channels etc... and how much you want to spend on the whole system.

As Bill said, loud is subjective.

Another option you may want to consider is using a component system. IE, SD-10 feeding an outboard amp or even a powered speaker.

I'm not a fan of "putting all of your eggs in one basket". By using an SD-10 and an external amp or powered speaker, you're costs remain roughly the same (if you go with a rackmount PA amp) or can be considerably less if you get a basic stereo home amplifier. For flexibility reasons, lets say you have a scene that you want to drive 2 huge 15" cabs. The SD25 is pushing it and now you're stuck using an external amp anyhow, increasing costs to drive your scene.

My 2c.

I have about 15 scenes with differnet background sounds ( plus one over arching sound system). I use BooBox's for scenes with ambient sound and a scare sound ( I have 8 of these) right now I am using DVD players and PA amps (using each channel seperately). At least one DVD gives me issues every night or the cd has problems. So far the amps have held up but it is only a matter of time. I haven't set a budget, it may take several years to change out everything, depending on the solution I settle on. I just want a no brainer system that I can rely on. Solid state seems to make sense, but one centralized system is out of the question, I won;t take that king of chance with my whole show.

Why not just go with a bunch of SD-10's with powered speakers in any of the rooms that are not covered by the boo boxes. Hell you could even just buy one or two and flood the rest of the rooms with some nice powered JBL's or EV's. Just a thought.
