  1. I have an empty ALTEC 9849-8D oak veneer single cabinet in Edina, MN 55424 for $25: https://minneapolis.craigslist.org/hnp/ele/d/minneapolis-vintage-1974-altec-oak/7357338675.html
  2. Hi guys - I'm a huge fan of the vintage FM tuners & receivers. I sold them at retail 1966 > 1974 in Minneapolis, all the big brands. Alignment is the magic that restores classic 1970's analog tuner performance! Like 50 year old sportscars, they need a tune-up. Major improvements in sensititivity & selectivity, less noise & distortion. I get 42+ stations on a 31" wire antenna when I'm done! EZ enough to DIY - most mfr's Service Manuals have alignment charts - you'll need tiny hex & nylon screwdrivers and some time. Let me know if I can help - PM me with your Tuner/Receiver model # - and your name & phone # - I talk much faster than I type!
  3. DLK and Omega were trade names of Don Kliewer who built them as house-brand speakers for Schaak Electronics in Mpls/St.Paul MN. Midwest Speaker Repair in Roseville, MN can help you with these - talk to the owner Joe at 651-645-7174.
  4. Highly recommended - latest model - sound quality blew me away - 3D soundstage on old Rock CD's! $200 w/ remote control! https://www.adj.com/ucd-100-mkiii
  5. Here's one in Minnesota, NO affiliation. https://minneapolis.craigslist.org/wsh/ele/d/stillwater-marantz-2230-professionally/7335291217.html I sold Marantz new at Sound of Music in Minneapolis 1970-74 - 2230's & 2270's flew out the door!
  6. Maybe it's just the cognac...
  7. Damping factor of the amplifier (speaker load impedance/amplifier impedance) diminishes as the speaker wire resistance increases. ADCOM 400 DF = 0.02Ω internal impedance. Add your speaker wire resistance and recalulate - you will be amazed how most systems have meager 40-50 DF's even with #16 or #14 speaker wiring! Do the math on your system! Look up the Ω/foot on your wire gauge, multiply by TWICE the cable length to calculate the round-trip electrical resistance, you will see! #12 silver-plated FULTON is magic!
  8. Flip the wires from the amplifier to the crossover inputs on both speakers. You can wire SPDT switches ($5 each) to do this quickly to A/B compare.
  9. Reverse the input phase to BOTH speakers - this will invert the ABSOLUTE PHASE of your system. You may find the sound is closer to what you remember.
  10. Many Klipsch 8Ω-labeled systems use 4Ω woofers to boost bass output measurements by +3dB. OK on horn-loaded systems where the acoustical loading increases the AC impedance at the amplifier. Questionable game of specsmanship when the marketing guys, not the engineers, write the spec sheets. Early KG4's were labeled 4Ω, quickly changed to 6Ω. Two 8Ω woofers in parallel are 4Ω, not 6Ω or 8Ω, kids! My Quartets, Forte II's, and Chorus II's - all sold as 8Ω speakers - have 4Ω woofers to generate that big BASS! Transistor amps deliver twice the current at 4Ω, tube amps limp along with transformer limitations & distortion. Measure DCR at the speaker terminals to see what you have for a load - the AC impedance won't be much higher.
  11. Keep your KLF-30's! You will miss the 1st-octave BASS missing on LaScalas, and you may be sensitive to the phase shift delay in the folded bass horn as it crosses into the midrange horn, like I am. Unless you can biamp and delay the mids & highs for phase coherence (time arrival) which can be easily dialed in by ear, I think you will be disappointed. You will gain a couple of dB loudness, at the expense of deep bass extension and phasing anomalies.
  12. T-Mobile offered me a $50 unlimited, taxes & fees included package because I'm a good 3+ year cellular customer. Their cellsite is one block, delivers 180 to 200 MB download, 60 upload on my $200 Motorola G8 Power.
  13. Measure the DC resistance at the input terminals with the amplifier disconnected, should be 5 - 6 Ω. If it's reading open circuit, maybe the kids jiggled a connection loose at the crossover.
  14. MC-2200/2205 IS 200W w/Autoformers, is an order of magnitude beyond 1's gen McIntosh MC-2100/2105 SS amps. Really woke up my Forte II's. I sold the MC-2100 when an ADCOM GFA-555 kicked it out the back door. Flabby bass, smeared upper highs, mids were beautiful. MA-6100 integrated sounded better at 60W.
  15. I just sold the Oak Chorus II's in Minneapolis tonight. Thanks to all here for your advice, I do appreciate it! Buyer was knocked out with the sound! His wife & daughter approved, and his Mom helped carry them out! Smiles all around, another happy new Klipsch owner! 😁
  16. Properly VOICING a speaker for an application determines how succesful the design will be. ALTEC used Western Electric research to VOICE speakers to shout dialog thru movie screens. PWK understood Living Room acoustics, properly VOICED Klipsch speakers for home listening. JBL just wanted to sell more speakers, tweaked the Boom & Squeak to make them sell faster! Who is winning? Hmmm...
  17. Subjective opinion debates about loudspeakers will go on for another 75 years! Folded bass corner horns have -720° phase shift, disconcerting to many listeners. Some don't hear it, some don't care, just want +6dB output for their 3W tube amps. Quartets, Forte' II's and Chorus II's are time-aligned, a huge difference for my ears.
  18. UPDATE Thursday 2/25/21 - 10PM CST Oak Chorus II's will arrive 3PM tomorrow when I will test them on a Marantz 5002 and shoot photos on a Sony/Zeiss camera. Woofer & Passive cones are flawless. Sides are gorgeous. Tops are smooth, have water marks. No risers or badges. Shoot me your direct email with an offer, I'll send cellphone photos from the 2nd owner. Better photos tomorrow. I see local prices have gone crazy - $1000 Forte II's on Facebook yesterday, $1800 Heresy HBR's on CL tonight! https://minneapolis.craigslist.org/ram/ele/d/saint-paul-klipsch-speakers/7282951221.html Please send your phone # and best time to call along with your questions - I talk much faster than I type! Cheers, Steve
  19. Install AudioTool on your phone or tablet, have a look at the analyzer while playing test tones from a CD. Keep in mind, most music contains almost nothing below 32 Hz.
  20. Damping factor only applies to amplifier control of a woofer. Once a cap blocks DC to a midrange, DF is irrelevant. Parallel 8 ohms will lose 3dB but maintain crossover. Give it a try!
  21. Thanks for your (mostly) instructive and helpful comments! I'm expecting delivery in a few days, when I will post photos of these speakers. Musician owner assures me they are firing on all 8 cylinders. They will be tested here w/pink noise on a 1/12 octave audio spectrum analyzer. I can supply - or install - Titanium HF diaphragms - I stock them here for Klipsch Heritage and KG upgrades. Opens the air above the music. Again, I can't offer a price yet since I don't know my cost! Innuendo like "We already know what they are worth to us" is meaningless jive BS without a serious offer. We all have the same Heritage Excel database. I will post a FOR SALE ad when they are ready to go. Thanks guys!
  22. I have a chance to buy back a pair of Klipsch Chorus II's that I sold to a local friend a few years ago. What should I offer the owner, and what to expect to sell them for, to be fair to everybody involved? They will need a new home - no room to keep them here - I have Klipsch stacked to the ceiling times 4! I can demo them on my ADCOM system and instantly A/B compare them with my Forte II's and Quartets. Thanks to all, I've been enjoying the Klipsch Forums for many years!

  24. Heresy's are sealed boxes, so they won't unload below resonance like a ported speaker. You could add a series capacitor to block lower bass frequencies the Heresy can't reproduce to take a load off your amplifier. Choose a value so Xc = 8Ω at 30 Hz or whereever you like. https://duckduckgo.com/?q=capacitive+reactance+chart&t=ffab&atb=v1-1&iax=images&ia=images&iai=http%3A%2F%2Flevetiere.pagesperso-orange.fr%2Flevetiere%2FFiches_techniques%2FEntrees%2F2010%2F9%2F26_Reactance_Chart_files%2FReactanceChart.png
