Jennings Research speakers

Hey all,

Just got these speakers pair, it's a 3 way the peerless type tweeter grabbed my attention and the built quality is superb, real walnut veneer and swivel pedestal.

I never heard about it before. I learned they were built in CA, besides that there isn't much information available online.

Sound like a fun project, it was a few scars and is missing a grill. I will decode the crossover diagram but would appreciate any information you may have.

Thanks,

    They were only in business about 5 years...if I remember correctly, the Contrara Rectangle, Contrara Pedestal and the Vector One were their only 3 products...

    Not much else out there for info...

    This is what I was able to pull out:

    "Each cabinet features (2) Audax French woofers and a peerless dome tweeter, 45 lbs each, 11.5" x 11.5" x 33.5". Made in California USA."

    Also:
    "Jennings Research was founded by Tom Jennings who was the head of marketing/design for JBL in the 1960s. It was founded in March of 1975.

    I haven't had the chance to listen. I hope all drivers are good.
    I am predicting that finding equivalent drivers will be a huge pain in the ****.

    Apparently these are quite respectable speakers built with quality parts...

    and so how do you like them? :*


    Nice surprise, really like the way these speakers sound hooked up with a Marantz 2270, The construction is outstanding, weighs a ton, about 50lbs each.

    They fit perfectly in my room and are super forgiving when it comes to placement. Just moved in and can't get the optimal placement for the CRS (I love).

    The walnut veneer on the Jennings needs some conditioning, would you be able to recommend the right product?

    A millworker recommend me Feed-N-Wax wood polish and conditioner on a solid walnut table I had made, would recommend this on speaker veneer as well? I learned here this is a no, no...

    Please advise, thanks

    Please dont use steel wool.
    You will never get it all out of the wood before refinishing.

    Not sure if it matters that I didn't do a refinish or used new Vaneer. Simply used this to rejuvenate old faded walnut. Either way it was a learning experience as the speakers were gifted, I'm still impressed by the difference after using the Howard's products.

    I like Howard feed-n-wax on unfinished solid wood. Veneer is a different story, I am afraid the oils may soften the adhesives and cause seperation...

    Thanks all for the useful comments B)

    Here is a pic of the crossover, pretty minimalistic 3 inductors and a cap and the woofers numbering... Sound is decent acoustic instruments have pretty good realism.

    Going back and forth between this and my restored and upgraded CRS, the CRS sound smoother but seem mid scooped in comparison.

  • I'm a fan of having the inductors perpendicular.
    A nice afternoon upgrade. :)
