    Question concerning the wiring of two sets AR2AX speakers

    I recall hearing that some folks would have dual sets of the famous AR2AX speakers. I think they would set one speaker on top of another on each channel. I know you could wire those without issue if you had two sets of outputs on your amp, but what If you only had one set of output channels...

    dual concentric speaker drivers

    Last winter I built a set of speakers using concentric drivers and really like the sound. So, I had another idea for homemade speakers that would employ dual concentric drivers, but can't seem to find suppliers for such speakers. There seem to be many such speakers available for car audio and...

    tube preamp mated with class d amplifier

    I've been interested in experimenting with a tube pre on a class D amplifier. I want to keep the price "low" by looking at used like ARC LS-17SE or new like Quicksilver line stage, non remote for around $1,000. The only problem I have with a new Quicksilver is the lack of reviews, hard to find...

    Dedicated Class D amplifier suggestion

    I have a desire to experiment with class D, however it seems hard to find mainstream brands that carry it. My idea is to have a class d non-integrated amp so I can experiment with different preamps to see how it affects sound. NAD has a number of class D options, but they are all integrated...

    My tube amp evolution

    I bought a cheap Chinese tube amp to get a tase of the tube experience as well as the ambience of the glowing tubes. I have a nice SS system in my living room and added this to the opposite side of the living room on a bookshelf along with a set of bookshelf speakers. The glow was nice and the...

    B&W 805 S2 speakers

    Does anyone have any experience with the 805 S2 speakers? I have found a pair locally on sale for $2600. They look to be in perfect condition, but I can find very little about them online. I have seen a lot of information on the 805 and the 805 S3, but not the S2. I am interested in how they...

    Elochen EL34 tube amp tube

    I have an inexpensive tube amplifier that has 5U4G tube, rectifier tube (I think) that sometimes has little lightning bolts on power-up. Once, it made a flash that was bright enough to light up my living room. From what i've read here, this may be impurities in the tube. My question: Should I be...

    Recommendations on new tube integrated amplifier

    Hello. I'm looking for recommendations on an American made integrated tube amp that won't break the bank. I want an American built amp that has good support should anything go wrong. I'm not interested in vintage because we don't have any good service people where I live, or at least I don't...

    Got a taste of tubes and I like it...

    So I bought a cheap Chinese tube amp, the Laochen EL34-B and matched it up with recently purchased refurb. Klipsch R-15M speakers. I have been quite delighted with the outcome. I set it up on a bookcase in the living room and my wife likes the look so nice outcome on that front. I'm enjoying...

    What would a modern speaker look like if....

    So, I have learned that the narrow, tall and deep design for modern floor standing speakers was due in large part to people who did not want speakers as big as refrigerators. So, if an engineer were given the freedom to design a high end speaker for audiophiles what would it look like? Would...

    can anyone recommend a book on different speaker concepts?

    I'm looking for a book that could explain all the different styles of speakers out there and explain in somewhat layman terms theory of operation (I'm not an engineer;)). Or, to clarify, some technical explanations are ok, just not looking for tons of calculus to explain theory etc. E.G. Open...

    Trimming one output on a two output C-47 preamp

    McIntosh C47 preamp question: My preamp has two outputs which I currently have setup with two separate amplifiers. The amplifiers power two sets of speakers in the same room. My dilemma is that one set of speakers are more efficient than the second set, 92db vs 88 db. I was wondering if there...

    speaker impedance in parallel

    I recently decided to experiment with my speaker configurations by hooking up my Paradigm Signature S8 in parallel with vintage Polk Audio RTA12's. I am unable to find the impedance of the Polks, but believe they are 6 ohm. The paradigms are 8 ohm and my Macintosh Amp has speaker taps rated at...

    About those dried out capacitors...

    So I have a pair of Polk Audio RTA 12 speakers which I purchased around 1981 or so. Since they are 37 years old I thought they would benefit from a crossover rebuild. I've never attempted a rebuild like that, but being handy with a soldering iron and having some understanding of electronics I...

    vintage vs modern speakers

    Within the last year, I've greatly improved my audio by purchasing new McIntosh amp and preamp along with a new Marantz CD player. I love the sound and was using vintage JBL L150 speakers. My local audio store got in trade Paradigm signature S8 V3 speakers which I auditioned in their special...
