I noticed the lower limit of the MPT-016 is 3kHz, but the recommended cross-over frequency on the Jack112 is 2kHz. Did you guys who used the MPT-016 alter the high pass and low pass filters accordingly (assuming jack 10 and 12 have same cross over frequency)? I assume the driver was OK with that? Also seeing as MPT-016 is over twice the power rating of the Pulse (not knowing what the Goldwood is myself), is it necessary to make up the full melded nest of 16 tweeters per cab or can one use 8 per cab and modify the electronics? I may PM about the spare tweeters.

Has anyone built any Bill Fitzmaurice (BFM) cab’s and used the CPC-supplied ‘pulse 306’ tweeter as below? The BFM cab build literature offers uk-based CPC as a retailer of the equivalent of the USA branded ‘Goldwood 1016 piezo’, against which the pulse version looks exactly the same shape and has the same external size. The CPC website confirms they are far-east manufacture and even BFM praises the Goldwood’s for being less than $2 each, so I would assume even the U.S. ones are far-east origin. Am just looking for ‘UK’ confirmation that this is not a bad idea; to buy 30-odd of these from CPC and start sawing and gluing them into pretty, but pants, melded arrays. (Sensible precaution: Would I need to buy more and test everyone one, somehow?)
