I have a pair of 18" woofers that came out of Magnat trans puls or trans pulsar 80 speakers. I'm looking for any info on them. So I can build a box for them. I have email magnat they have no info since they have been bought and sold over the years info lost. But they did tell me what they were out of. Also contacted Magnat museum all they had was a brocher on them couple photos of the speaker they came out of. I sent them a dozen pictures of them. I was hoping someone has a pair of these and can give me some info on them. Thanks for the help. Ray44
