Does anyone in the GTA or close to London, ON have expertise and equipment for measuring loudspeakers? I have a new pair of DIY 3-Ways that I would like measured and I would like to learn how it is done. The speaker crossovers were done by Dennis Murphy. The drivers are 10" Peerless 850146 (obsolete), Seas W15001CY mid bass and Raven R1 ribbon tweeter.
