    Supporting "Genesis" Loudspeakers

    As far as we can, we have been trying to keep customers of older Genesis loudspeakers going. Many of our owners have had their loudspeakers for 15 years or more. This sub-forum is intended to support all our customers - old and new. Great loudspeakers do not just die, they fade away, but they can also be injected with new life!

    First, a bit of history.....

    A previous company, Genesis Physics also made loudspeakers under the "Genesis" brand. They made high-quality, low-cost loudspeakers from 1975 to 1987. However, that company is totally unassociated with the current Genesis Advanced Technologies. However, parts may be available from www.humanspeakers.com.

    Genesis Technologies was the previous company. They made loudspeakers in California, and then in Colorado from 1991 to 2000. They closed down during the stock market crash and were foreclosed by a bank. Genesis Advanced Technologies bought the assets, trademarks and intellectual property from the bank in 2002. Unfortunately, in the 1+ years that the company was closed, the bank managed to lose most of the assets and intellectual property. They even managed to let the trademark registration expire! However, we have tried as far as possible to recreate some of the old technology, and we do try to support the customers of the old company - as far as we can.

    Genesis Advanced Technologies was founded in 2002 to carry on the brand, but unfortunately we have had to re-create a lot of the original technology. We also took the opportunity to improve upon the legacy started by Arnie Nudell with the Infinity Servo-Statik 1 in 1968. A lot of the new technology can be retro-fitted to the original designs (but we cannot do anything with Infinity loudspeakers - so please don't ask), but unfortunately we cannot roll-back prices to the 90's. We have also re-manufactured some drivers if plans/specifications are available.

    So, if you own a pair of old Genesis loudspeakers, and you do not find a support answer here, post a question and I will try to answer as soon as I can.

    Bully for you Gary! Genesis and Infinity are intimately associated with the history of high-end audio! My friend still has his RS1bs

    Thanks, Myles. I wish I could support the big Infinity speakers, but I can't. Some of these 30 year old speakers still sound wonderful and would run rings around some of the current offerings.

    Miller Sound has limited support for the IRS's and there is a guy in KY (I think he's a DR. and super Infinity fan and hobbyist) who sells and supports them on ebay. I remember my last listening session on IRS Vs at Millers Sound... it was wonderful. I was an RBIIb owner and wished I had Ibs. The Ib guys would tell me they wished they had IIbs. The grass is always greener

    Thank you Gary...for your commitment to support discontinued models and your appreciation for the passion music lovers like myself have for vintage but wonderful gear. With many of the smaller audio companies out of business or offer little to no support at all...it's encouraging to see that companies like Genesis, PS Audio, and others seem to really care.

    The reason that I'm here is because I took a chance and bought a pair of APM-1's that I believed had bad amplifiers. I figured that it was practically a no-brainer since the price was right and I wouldn't need to put them into use immediately. I've been researching extensively for a solution that is practical. I understand that Cullen Circuits would repair the amps at a fair price when they were still in business and (trustworthy) local electronics repair shops won't touch them without a diagram. I spoke to a shop that is out of state specializing in amp repairs for subwoofers and pro-audio but they would want to see the amp before determining if they can do it or offer an actual price quote. I heard about an APM-1 owner that replaced the amps with DIY subwoofer amps and obtained good results but since I've never heard the speakers function properly I'm a bit weary of upsetting the frequency or sonic performance of the speakers. I'm obviously looking for the most economical solution possible since I'm audioholic and still need to support my family first.

    Thanks again.

    Welcome to WBF, and I appreciate your bravery!!

    We did not continue making the APM-1 because the bank had lost all the schematics to that model, and we were unable to repair the amplifier. Unfortunately, many failed. We have a replacement amplifier, but that comes from the Genesis 5.3 (modified to work with the APM-1's single 15-inch woofer) but that is expensive as it's 2013 prices and not 1997 prices. Rhymik Audio makes a range of subwoofer amplifiers that are far cheaper, and we've heard that they work "good enough" but I have not tried them myself. However, as their servo design is quite different from ours, you will also have to replace the woofer.

    Good luck! And don't hesitate to ask if you have any questions.

    Genesis 350SE crossovers

    Hi Gary,

    I have a set of Genesis 350SE built possibly around the year 2000. I've noticed that the high frequencies are not as bright as they used to be. All 15 tweeters work and I've played with the two knobs on the back but still nothing. Do you think it could be some crossover component that's causing the problem? I wouldn't think the capacitors would go out in 13 years (but I don't know) If so, is there one capacitor that handles the tweeters that I could replace? (The mids sound beautifully!)

    By the way, I've connected other speakers to the same system, same amp, cables, etc, and it sounds fine, so I'm guessing it's the speakers.

    Thanks in advance for your help!

    The only crossover component that might deteriorate would be the big 220uF 400V non-polar electrolytic that protects the midrange from lower frequencies. The tweeter circuit is just a high-pass and uses very high quality film-and-foil capacitors that won't deteriorate for the next 200 years or so.

    If I were to suspect any component, since the speakers would be 13 years old now, might be the tweeters deteriorating resulting in lower efficiency: magnetic flux loss due to aging - especially if it's very hot in San Antonio; diaphragm de-laminating or corrosion due to ozone, cigarette smoke, etc. Another possibility is that some of the tweeters aren't working.

    Hi Gary,
    Thanks for your super fast response!! Well, after you told me that it was unlikely that the crossovers were the culprit, I went back and started playing with it again. Since I was trying to get more treble, I had turned the rear tweeter control all the way clock-wise, based on what I had read in the setup instructions: "The left hand knob is a volume control for the rear tweeters. Turning this control clockwise will increase the level of the rear tweeters. Use this control if you need a bit more treble or to increase the apparent space of the soundstage." So I had turned them all the way clock-wise. Then while sitting in my listening position, I asked my son to turn it all the way counter-clock-wise and WOW! My high frequency came back!! But, that's the opposite of what the manual said. I did notice that the volume of the rear tweeters do increase by turning it clock-wise, but at the same time, it reduces -significantly- the volume of the front tweeters, which I wasn't expecting. Would you know if it's supposed to do that?
    I'll play with it a little more to try to find a balance, right now I'm happy with the front tweeters, but I'm missing the spacious soundstage that the rear tweeters provide.

    Thanks for your help!

    PS. It does get very hot in San Antonio, but inside the house is usually 76-80 degrees. If you're ever in San Antonio (or Austin, Houston) let me know, I'd love to buy you dinner and have a nice conversation.
