Pair of Infinity Qb Quantum 10 inch original woofers neoprene surrounds. Listing is for the pair of drivers only Sound is very impressive, both are in good shape, one has a dent in dust cap but is still tightly affixed. Harvested from a pair of Qbs with blown out tweeters and mids I have used these for almost 10 years in a pair of Reference 5s. Specs: Recommended Amplifier: 15 to 150W Crossover Frequency: 600 Bass: 1 x 250mm

Hello,I am selling my Rare Pair of infinity Quantum Reference Standard QRSComes with Crossover and Super Rare Sweet 16 woofers.The manuals are included.These are in perfect working condition. They sound great.These are in As Pictured physical condition.I would like to point out these things.The 4 extra wood panels they are not included. I never had them.The crossovers for the midrange and the tweeters are mounted on back of panels so they can be used apart from the woofers. They are set up for bi-amping.The grills and woofer cabinets on the top along the fronts, have been touched up, as pictured.The grills are included . They have all the connecter tabs for the woofer grills. The grills for the panels 1 grill has all 4 connecters and the other is missing 2 connecters on grill. It holds on but not the best. I never use the grills, so not a problem for me. The woofers on the left in pictures have had 2 woofers replaced, they are slightly different color. As pictured there is 1 little metal tab missing on 1 midrange. Dont affect, it works perfect. All drivers work perfect as they should.The midrange drivers have been rewired with Straightwire Music Ribbon speaker wire. Arnie Nudell, then president of Infinity, decided that the original configuration of the QRS with a 15” Watkins driver was too slow to blend well with the ribbon/planar midrange drivers and tweeters. So, he built just a few with 16 ea. 5-1/4” drivers in the sub cabinets. The entire system, called the Infinity Quantum Reference consists of 40 EMIT tweeters, 6 EMIRM midrange, and 32 5-1/4” dynamic drivers. Short of an IRS V these are the best speakers bar none that Nudell ever made for Infinity. The soundstage is amazing, the tonal quality is to die for and leaves any and I mean practically any state of the art speaker as a toy. The Strathearns have a superb midrange and those EMITS are longer than the later ones with no short cuts done in their engineering. They are as smooth as any tweeter ever made. Old audio collectors must know that the late Harry Pearson of the Absolute Sound considered this among the most natural speakers ever produced.Musical instruments sound as real as you could possibly hear whether you play vinyl or digital media. Local Pick up only. If you have any questions please feel free to ask, thank you!

Offered for your consideration is one (1) Infinity grille emblem removed from an Infinity Quantum-series Qe speaker, USA-manufactured in 1978. Please take a look at my large photos, the measurements, and read the remaining description to decide if this Infinity emblem is correct for your needs. This Infinity Qe emblem is in clean, nearly excellent condition. It is made from aluminum alloy with a black-enameled background and measures 1¾” square. There is one faint longitudinal scratch and bottom-edge scuff, as pictured, but is otherwise flat and perfect. And, the back side has some factory adhesive residue remaining which will make a good base for the contact cement or other type of glue that you will use for mounting it to your Qe grille. It’s in pretty nice shape overall. This is a great find if an emblem on one of your Qe speakers is missing or ruined and will have your cherished speakers looking as great as they sound once again! So, as pictured and described, this Infinity Qe grille emblem is offered at a competitive price.
