We enjoy taking brand new things apart and the SP2500 is no exception - we just had to know what's inside. Starting off with the satellite speaker, it's obvious that the drivers here are in a whole another league compared to those on the SP2200. The magnetically shielded bass cone is really quite impressive.
Peeking at the subwoofer we can see the bandpass housing with a sealed back part and a vented front chamber. Unfortunately it's hard to get a clear view at the 8" subwoofer as the box is glued shut around it. The housing is very sturdy and as we can see the amplifier and power supply plates are held on with ten screws each, so they shouldn't leak either.
A look from the other direction shows the frame and magnet of the driver. Just like all the other cones, also this one is made by Eastech, but there's no other information available. Also here one can see a quality issue, some glue has fallen on the frame of the speaker and also made its way to the backside of the cone. Luckily this spill hasn't hit the inner suspension, but any off-center extra mass sure isn't going to help when the subwoofer is pushed to its limits.
And finally a view at the circuit boards, power supply on the left and the amplified board on the right. The power supply is mounted to the vented chamber, so it's cooled by the airflow through the port. The very efficient amplifier chips on the audio board are connected to the aluminum mounting plate which should be enough to keep them cool.
