What would you do with Philips 22AH587
Hi again,
I guess there are some older r.a.p poster here, beeing the half life in the audio domain, so I challenge you with a question of an old pair of loudspeakers. For those who know the Philips 22AH587/00R studio speakers: How would you use them? The Philips are very old but are triamped. The Bass speaker is MFB (Motion Feedback) I guess they have some sort of a piezo or coil to messure the membrane movement, this will be feedbacked to the preamp to enhance the impuls response - I guess! They have gyrator-filters for room correction, they take everything from line to loudspeakerlevel as an input and the MFB and the gain of each amp can be adjusted on the back. So far I would use them for mixing or as a reduced set for mastering. But they have a problem! 1. I guess the controls on the back are not calibrated anymore - They look very diffrent for both speakers and it's not easy for me to adjust this for linearity. 2. One midrange speaker was brocken (the connection wire to the coil was burned), I openend the midrange speaker, took one winding of the coil to have a new connection, soldered it to the cable and now it is working. But I heard, that as soon you disassemble a speaker, pull the coil out of the magnet, the speaker is ill. The speaker has a huge magnet and over this magnet there was a plastic cup. This cup is broken now, and I think the midrange speaker recieves too much air from the bass speaker. My questions now: Do you know the Philips? How do you like them? What would you recommend to me how to use these speakers? Do you recommend me not to use the speaker due to the fact that they are not adjusted (can I do this - how?) and/or the fact that one midrange speaker is handicaped. (There is a slight difference between both midrange speakers in sound, but not very extreme) all-in-all, what would you do with them? I think they were nice speakers for their age! Thanks for any comment, Lukas |
