Guest Posted January 22, 2003 Report Share Posted January 22, 2003 I have a pair of AR91 speakers that I bought in 1981. I am using them as front speakers now for a wide-screen TV, and I am trying to add a center channel speaker(and maybe side or back speakers as well).According to what is available from AR today, either AR4C or AR2C could be a choice, but they use 1" and 5 1/4" (all of current AR center channels use these sizes) tweeter and drivers. I wonder how it will sound with AR91's 3/4" and 1 1/2" elements. The manufacturer suggested AR4C as the closest match.I read some of questions and responses in this forum, and I expect that an AR92 or something like that may be suggested as the center channel. My room is however pretty narrow such that I would like to attach the center channel behind the TV set, which is against a wall. I would prefer a smaller size.I am no expert in speakers, and have no experience about "voice matching". Please advise.G. Lee Link to comment Share on other sites More sharing options...
ar_pro Posted January 22, 2003 Report Share Posted January 22, 2003 It's tough to see how the AR4C can be considered as a good complement to your AR-91's...it has a limited frequency response, 6 dB difference in efficiency, a crossover frequency that's about half of the 91's mid/tweeter crossover of 7.5 kHz (that's going to sound *weird*), and a sparkly little titanium tweeter. About the only thing going for it is the magnetic shielding.It can be difficult to integrate vintage AR speakers into a video/surround installation...none of the speakers were shielded, which can be a real problem with the tower cabinets of the 9 and 90; and matching the center channel's voicing to the other front speakers is a definite challenge. Suggestions, anyone? Link to comment Share on other sites More sharing options...
Guest Nigel Posted January 23, 2003 Report Share Posted January 23, 2003 Hi;Voice matching means that the speakers will work together, nothing currently sold under the AR brand is close to your AR91 speaker.I would consider putting an AR92 upside down above your TV. If you put a 1/32" of steel sheet between the TV and the speaker, that should take care of an shielding issues. THen if you get a six channel system, you can use the other one for the center rear.There is a pair of AR92 on ebay right now.For surrounds; AR9, AR90, AR91, AR91.5, AR92, AR92.5 (not sure if this was available in the USA). These are "voice matched".I have two pairs of AR9 speakers, and a pair of AR91.5 that will eventually be incorporated in a 7 channel music/home theatre system. I have not decided on the center channel. I am considering build one with the same mid and tweeter as the AR9x speakers, and an 8" are AR18 woofer, in a box a bit bigger than an AR18. The crossover network would be the same as an AR92.Be careful with HT receivers, many are not up to driving the AR91 speakers. I can only speak about Onkyo's which will handle them okay, not as well as an Adcom amp, but they won't smoke.Nigel Link to comment Share on other sites More sharing options...
