Where can I find plans for a Belchfire/Maximo/etc. speaker cabinet?
• ElectroVoice sells (?) makes available (?) plans for cabinets for their speakers. • Copy an existing cab. • Some cabinet fitting suppliers have example plans. • — (addresses in a future posting) — Back to the GEO Home Page Output transformer questions: Q: Do output transformers sound different from one another? If so, why do they sound different? Can you for instance wind a transformer to get an intentional frequency response? Like, you think your Marshall has too much midrange, so you put a new OT in that has like a 6-9dB cut around 800hz to get a natural “scooped” sound? A: These things cause transformers to sound different: • High and low frequency roll-offs caused by the details of the iron, copper, winding and manufacturing processing. • Inherent distortion caused by the magnetic properties of the iron and the driving impedance • Excess distortion caused by lack of coupling between sections of the windings – literally where all the windings are in relationship to one another
