  1. Item: Infinity RS4000 Speakers, black, 8" three way, with Emit K tweeter Location: Sydney - Hills District Price: $175 Item Condition: very good, see photos Reason for selling: too many speakers Payment Method: Pickup - Cash, Paypal, Direct Debit Extra Info: These are quite heavily built cabinets and host an 8” three-way design with EMIT K ribbon tweeters, hence the extended upper frequency range to bat levels, 45kHz. The sound is clear and spacious, the bass tight and down to 45Hz. Recommended power covers a wide range from 25-125 watts, and at 89dB efficiency you have a fair bit of leeway. I'd tend towards the upper third of that range. Nominal Impedance: 6 ohms Power Recommended: 25-125 watts RMS Sensitivity: 89dB @ 1 watt, 1 meter Crossover Frequencies: 800Hz and 3,500Hz Frequency Response: 45Hz-45kHz +/-3dB Dimensions: 57cm(H) x 31.75cm(W) x 26cm(D) There’s a tone adjustment on the back to fine tune for room acoustics. According to the included manual there’s a protection circuit for the tweeters. Probably get best sound when used with short stands (maybe 250-300mm) but they can be floor standing and still work well. Update: I have an old pair of metal stands about the right height that can be added for $25 the pair - no time to photo at the moment. Freight: ask me about this. No boxes at the moment. Photos: Advertisements without photos of the actual item will not be approved.
