Please keep this in mind when reading the listening test. These are really inexpensive speakers so you should be aware of what you can expect from them. The Ref 1 mkII have been extensively tested in different operating conditions, both as main speakers of a budget system, as main speakers into an expensive set-up and finally as rear speakers into a good Home Theater system. This model seems not to be available in the American market and a plate in the rear of the cabinet tells us the whole story: Made in Denmark, exactly like many other US speakers, some JBL models, for example, like the Ti 600i we've recently reviewed here on TNT-Audio. The Infinity Ref 1 mkII are on the small side at 19,8 (L) x 34,4 (A) x 20 (P) cm while the weight is somewhere around 6 kgs (12 lbs) per speaker.Įasily available almost anywhere, it won't be difficult to buy 'em for a price sensibly lower than the suggested retail price (your mileage may vary). Frequency response: 65 - 20 kHz (+/- 3 dB).The cabinet is available both in black and simil-oak vinyl finish and it makes use of "rounded" edges to minimize diffractions. No biwiring is allowed - obviously - considering the price target of the speaker. The baby Infinity is one of the more affordable speakers into the catalogue: a standard 2-way rear-firing bass reflex enclosure, equipped with a 13 cm (5") graphite-coated woofer and a diminutive gold (?)-plated tweeter. It suffices to say that the US-based Company is certainly one of the largest in the Planet and that it has been making HiFi loudspeakers for 25 years already.Īs many other HiFi Companies, Infinity has a line of products specifically designed and built in Europe to satisfy the European standards and the Ref 1 mkII is one of those. No need to waste time and Kb to explain the role a Company like Infinity has played and still plays in the world of HiFi loudspeakers. Product: Infinity Ref 1 mkII bookshelf loudspeakers Infinity Reference 1 mkII - loudspeakers Bright entry-level Replaced by the A-4010GSL in 1973 with a swap of the Permalloy heads for entirely new HD Ferrite heads (but a permalloy core) and the replacement of the 1/2mil button by a " rec pause" function.Infinity Ref 1 mkII The rest is early 1970s mid-end Teac : two eddy current outer-rotor motors, one hysteresis synchronous for capstan, wide-dynamic rec/play amplifiers with mic/line mixing etc. Soon to vanish, the center button (between the reels) sets tape tension for 1mil or 1/2 mil tapes. Also necessary for this planned-in-advance automation : a second play head !
The automatic reverse mode was retained from the earlier models : automatic being if one has previously glued a piece of conductive foil at one end (or both) of the reel tape - a very manual automation in the end. SLH, or Low-Noise / High-Ouptut tape, have a higher saturation point and lower inherent noise so recording levels can go further in the red :) By 3 dB. I believe the A-4010SL to have been export-only (but I could be wrong.)Ĭompared to the 1960s versions, the A-4010SL brought SLH tape compatibility, separate bias & eq selectors, slightly different cosmetics and switchable meters (tape or source display) and meters' scale ( +3 dB) to allow better monitoring when using SLH tapes. As often with Teac, available in quite a few versions : from the 1966 A-4000 and A-4000S, the A-4010, the A-4010S ( 1967) and the ultimate A-4010GSL in 1973.
