Ojas There are other posts here on Ojas. There is a new NYT article today. Seems to be an update on Altec - targeting wealthy individuals that are expericing quality stereo sound for the first time. The principle to Ojas is a former fashion designer...

Great article in the Atlantic about the lack of innovation in the music industry. There are a couple of quotable nuggets that apply to more than just the music industry. I recommend that you read it to the end! https://www.theatlantic.com/ideas/archive/2022/01/old-music-killing-new-music/621339/

I just streamed a live show of Hot Tuna playing at the Freight and Salvage, in Berkeley. If you are a fan, it was a really great performance. I originally planned to attend in person, at the last minute Freight offered the streaming option, so I did that. They played for about 2 hours and...

Several months ago I pick up a pair of Realistic Nova 9 speakers. There are several posts on AK, about these speakers- sold in the early 70’s. They are large and include drivers sourced from University (possibly the T-202 Sphericon Tweeter) and Altec (possibly the Altec 405-A). I was not able to...

Greetings I just picked up a pair of ADS L880 that had been in attic storage for 20 years. I am listening and they seem a little bass shy. Great mid range, though. I am driving them with a big Sony (DA90000ES) and listening to a few of my favorites (Flying Burrito Brothers, Jack Hardy). These...

Locked-Down and living in the basement. All is well, mostly. Except many of my unfinished projects are staring me in my face. Take my JBL L20t for example. I like the L20t, the pair I have now is my second. (I gave my first pair to a friend in need). About a year ago I found this pair - for...

Nice read https://www.nytimes.com/2020/04/28/arts/music/electric-recording-co-vinyl.html?action=click&module=Well&pgtype=Homepage&section=Music

I saw the movie 'Parasite' last night. The highlight for me was when an exotic pair of speaker (tube amp and turntable too) came into view. They are up against the wall. They might have a folded horn for the bass, or just side ports for bass reflex. Does anyone want to hazard a guess as to the...

Local garage sale find, today! These speakers were made by a notable figure, Roy Cizek (https://en.wikipedia.org/wiki/Roy_Cizek ). Roy worked for and knew the giants of the audio industry. He also started his own firm(s) that produced highly regarded products. So, I need to re-foam (on order...

I stumbled on a 302A variant this weekend at a local estate sale. The cabinets are big ...5.7 cuft and heavy. I suspect it is a custom cabinet made locally here in CA, for Bozak components, in the early 60's. They are in very good condition. I peaked inside the cabinet and spyed Bozak...

Any thoughts on the speaker manufacturer and model? Thanks for your help!

No they are not connected, just on display (that the 'HIFI' bar in Tucson) so that college kids have something to do once they reach their alcohol consumption limit.

Purchased two pairs of the Dynaco A-40XL. This is a close relative to the A-25, but with a different tweeter and a larger cabinet with an internally vented aperiodic vent. This design was meant to be an improvement on the A-25. It took a little while to figure out which model I purchased...

Nice little article on Meyer sound http://tinyurl.com/ojkofzu 300 employees, now that is impressive.

Several news sources are announcing the death of Radio Shack, toady - 1 year after the snazzy superbowl ad and a new high paid CEO. "Update 5:45 pm ET: A press release from the New York Stock Exchange on Monday night said the exchange is taking action to delist the common stock of...

Aluminium has beneficial performance characteristics for sound reproduction. I am sure that I read that some place. Aluminium baskets, Aluminium tweeters hey woofers want equal time! Vintage Fisher, baby! http://sfbay.craigslist.org/sby/ele/4840341592.html Apparently preferred by tube amps!

I stumbled on a pair of AR91 speakers this weekend, that included a Fisher 700T. The woofers, of course, need to be refoamed. I pulled them out and popped in a pair of AR3a woofers that I had recently refoamed. Though they look the same I understand that they are different, so this is a...

You Do! Well if you live in the Bay Area - 4 (count them) Klipschorn speakers are available for only $1000! http://sfbay.craigslist.org/eby/ele/4417456995.html no Affiliation, don't have a truck; don't have a room with 4 corners!

Boy, that must have been an expensive commercial. "Feb. 04--A day after being lauded nationally for airing one of the best Super Bowl ads, RadioShack saw its stock price plummet on Tuesday as The Wall Street Journal reported that it's planning to close about 500 stores." Opps - REVISED! March...

I picked up this 1960's vintage cabinet today. Inside I found a 12" JBL D131, no other components and no crossover. The cabinet was made by Acousti-Craft and has a layout that is very similar to the JBL C37, with an opening for a 3 1/4 inch tweeter and a vent that is 3 1/2 inch wide by 12 inches...

Greetings! I just acquired a non-working Kenwood KR7400 (a nice little 60 watt amp from the 70's). I opened it up and cleaned the controls. I connected some speakers and a CD player (no output). No sound from the FM section either. I did not connect headphones. I then measured the DC...

Hear the very first sound ever recorded! Learn about the optical techniques developed to preserve ancient sound recordings! What does all of this have to do with Micky Hart, the Grateful Dead Drummer, and why did Thomas Edison bury his inventory of the first talking dolls...

I happened on a pair of these vintage bookshelf speakers, for free. Apparently they did not see any use in 5 years. Previous owner was moving on Tuesday moving and had decided to dump them. I hooked them up this morning and turned them on - low volume and low power (amp). They sound good, all...

I happened upon a pair of Fisher XP18. These are big speakers with an 18" woofer. I have two repair issues which I would like your opinion. First, one tweeter is damaged - it has a compression dimple. I have tried to correct dimples before - using a vacuum. Does anyone here prefer an...
