I’ve had requests from my rubberband ball viewing audience to make a video showing how to start building a rubber band ball. I’ve built many rubberband balls over the years, but the two largest are 150 and 300lbs. I even drove to Delaware once to see the then current world record ball that was about 3000 lbs that John Bain built. It’s a fun and enjoyable little hobby that keeps the voices in you head quiet for awhile. But be carefull, it can be addictive!
Thanks for Watching!
An interesting find here… A pair of the quite rarely seen Altec 422-8A woofers. These somewhat rare woofers are often considered as Altec’s answer to JBL’s legendary D130 (and variants) woofers.
To answer the usefulness found in JBL’s watershed D130, many years later .. Altec designed this excellent woofer — a beautiful combination of Altec’s best 416 syle Altec frame, with a special tighter, lower excursion cone, featuring an aluminum dust cap. This production-experiment resulted in a woofer that could handle more power, with almost 100db/1w/1m efficiency, and an more extended frequency range of 50-7500 cycles. This was a radical design for Altec, and worked quite well — maintaining the signature tone and detail that Voice of the Theater components were cherished for.
The 422’s frame, is the same high quality casting as the 515 and 803 and of course 416A/B and Z (circa 1960s). It’s quite possible and very common practice to have the 422/418 Alnico reconed into the 416 — by replacing the cones. That would be a shame here — because this is a beautiful looking and nice working pair of originals — though it is always a wonderful option to have at your disposal … if you ever need to.
As they are — , and normal to loud HiFi listening levels — the 422 represents an uncommonly nice sounding configuration in low frequency driver. Since they have a nice low cone resonance — they are still effective woofers — and with less rolloff they will work well in compact systems with smaller horns that don’t have such a low cutoff point — exactly what JBL did in many of their systems — using the D130.
The 422 8Z is a terrifically viable
By the mid 1960’s JBL had progressed from a cash strapped boutique HiFi speaker manufacturer to serious competition in the studio recording, cinema and musical live performance markets that Altec Lansing had held tightly since the 1940s.
JBL realized their aluminum dust capped D130 was indeed a superior woofer especially for live music — able to perform more evenly in smaller stage cabinets — and giving musicians exactly what they wanted — detail in the lower mids and vocals — that horn dependant Altec sometimes lacked. Eventually by the early 1970s JBL had a reputation for live music – and was considered the premium selection by Fender and others.
The 422 was not advertised by Altec, and was an unsung product — receiving little to know mention in catalogs — it did not become known good speaker until years later — and few were sold.
The Altec 422 was also referred to as the 418B in some older catalogs — where it is shown with a cosmetic tin magnet cover. The 422 8Z was used throughout the Altec Voice of the Theater line — ceasing production due low sales — as Altec lost the battle to win the battle of live stage sound reproduction of the 1960s-70s.
The drivers are guaranteed to arrive 100% safely, no DOA. They include all you see in photos, included old reproduction papers, test reports for each driver and info shown.
Even after Jim Lansing’s death in the late 1940s, Altec largely constructed their quite faithfully to the postwar 1940s design he left with the Lansing company’s buyout.
By the late 1940’s — while the new JBL company hyped new designs like the D175 and D130 — under great R&D constraints … Altec happily churned away refining and mass producing variants of the 1930’s Lansing design with a few manufacturing refinements and material changes (to both the body and cone).
Interestingly though, it was not until the the late 1960s –there were never any radical ideas — until the introduction of these briefly made 421 and 422 woofers, along side the 808 and 290 drivers with Symbiotik diaphragms… We see and hear any hugely radical changes in tone, and performance and various points. These strange looking variants were born at a time, where Altec wanted to offer bigger wattage handling — but rather, what they gleaned was a few notable behavioural tweaks … giving these woofers a more extended range, like JBL’s D130.
Over the years they have been often overlooked; and when coupled in smaller or medium/large systems, they perform faithfully, blending alongside all of the other horns and drivers Altec made.
If you plan to use a smallish 500 or 800 cycle horn (or something even smaller) and you have a small or medium sized room — don’t overlook the 422 and it’s hybrid JBL like cone.
