This video shows how to technically evaluate the speakers in a batch, so that they have similar characteristics, thus allowing you to create a more accurate project. The coil resistance, resonance frequency and SPL are evaluated.
Some care is needed when choosing speakers for a speaker cabinet project. When we decide to go for cheaper speakers, it may happen that some are defective or we may be forced to select from a batch those that sound similar.
