Giorgio AR Posted March 16, 2019 Report Share Posted March 16, 2019 AR-2t is not a mistake, but it is an idea to improve the mid-high frequency of my AR2s. At the moment I have connected in parallel a couple of AR-1MS to the older sisters AR2 (I have also turned the speaker upside down to have the 10 "woofer closer to the middle / high part given by the AR-1MS pair). I disconnected the bridge connection that fed the original pair to eliminate the original tweeters. As you can see from the attached photos, the AR2 pair is positioned above the AR2a pair, both are powered by a Philips RH 521 amplifier (30 wx 2 on 4 ohm the declared power of the amplifier, more than enough power to deliver a good sound output.) How the AR2s sound with the additional "tweeter": noticeably improved the high frequency, the mid-range is very present, in comparison, for the same volume delivered, the AR2 AR-1MS complex, has mid and more sound pressure compared to AR2a (I suspect that the perceived sound seems to be about 3 db higher than the three-way sisters). Very, very satisfying and a lot of improvement in distinguishing the musical instruments of the played songs. I would like to have an advice to be able to insert a correct crossover filter (maybe just a coil?) To make the AR-1MS work as a medium / high unit (not as a fullrange speaker), removing the overlay of low frequencies, leaving the only AR2 woofer to deal with bass. I understand little about electronics, I have no ability to design a correct crossover, I hope to receive valuable advice and help from authoritative and competent CLS members.
