| so bass traps in corners do nothing, it seems we have been fooled. or are being fooled. Below 60Hz is sub-bass? The lowest frequency produced by a standard 4-string bass (acoustic and electric; why do people insist on calling an electric bass a bass "guitar"? That’s an oxymoron!)---the E string played "open"---is 41Hz. That’s not ... | |
| Building Resonance Free Subwoofers When I spoke with Roger Modjeski (of Music Reference) about mating subs with the old QUAD ESL loudspeaker---of which he was a huge fan and owner, he recommended employing a crossover frequency of 100Hz, with 4th-order filters in both directions... | |
| Building Resonance Free Subwoofers Great stuff @mijostyn. It is my opinion that most hi-fi’s I hear are lacking the "gravitas" of live music, the massive bass foundation of music heard in concert halls, and even smaller venues like bars and clubs. It is the bass frequencies tha... | |
| Can an owner's manual and schematic be found for an Electron Kinetics eagle 7a power amp As is the case with many smaller vs. bigger amp models from the same company, the lower-powered Eagle 2A was considered the overall best sounding Electron Kinetics model. It was particularly known for it’s unusually good reproduction of bass fr... | |
| Quality of recording while evaluating speakers J Gordon Holt (founder of Stereophile) recommended his readers do as he did: make your own recordings. I did so, recording my son’s speaking voice (a brutal test of loudspeaker coloration), my drumset, and my band playing live in a club. A pair... | |
| Building Resonance Free Subwoofers By the way: Rythmik sells the factory-built F15HP with a 3 cu.ft enclosure, but for DIY buyers recommends a 4 cu.ft enclosure for greater minimally-greater output at very low frequencies. I did 4 cu.ft., which ended up measuring 24" H x 18" W x... | |
| Building Resonance Free Subwoofers Wow, and I thought my design and build was extreme! I originally was going to make the enclosure for the Rythmik F15HP DIY kit employing the design Danny Richie shows on his GR Research website: a double-wall box, with the space between the tw... | |
| Whats on your turntable tonight? Dang @slaw, Giddens, Cooder, and The Band. Don't get no better than that! Follow it up with Bring The Family and The Houston Kid, and call it a day. | |
| Townshend Pods under TT Don’t Do An old technique for suspended floors is to install a jack directly under the location of the turntable, applying just enough pressure to stabilize the floor. That assumes the area under the floor is just a crawl space, not a basement. In the c... | |
| Quality of recording while evaluating speakers Focus on the music, and accept the fact that recorded sound quality varies. What's the alternative, to be miserable? | |
| MoFi v/s UHQR Oops, not 15kHz, but rather 15K ohms. The Deccas (and to a lesser extent the Londons) can benefit from a lower than standard 47K ohms input impedance, and a little extra capacitance. In the late-1980’s I was graced with a phone call from Decca... | |
| MoFi v/s UHQR Yeah @sokogear, while with mc pickups you need to have enough gain, with the Londons and Deccas you need to have not too much (for low noise and freedom from overload distortion). In their Mani phone amp, Schitt Audio includes a gain setting of... | |
| Rythmik Audio F12/F12-400 vs JL Audio E-Sub e112 Yeah @harpo75, the "regular" Rythmik (and GR Research) subs---like most (all?) others---will play up to little more than 100Hz. The woofers in the OB/dipole Sub are designed to work in "free air", and the Rythnik Audio plate amp included with t... | |
| Townshend Pods under TT Don’t Do @ghdprentice: Let me add that when going the wall mount route, if possible do so on an outer wall. If that is not possible, on a load bearing inner wall. | |
| Need A 10-30 watt Tube Power Amp, Lower Heat Output, Which Sounds Great, Under $1500 Used A strong second recommendation for the Music Reference RM-10 (look for the improved Mk.2 iteration). Though the designer/owner of MR (Roger Modjeski) passed away in 2019, product servicing remains available from an engineer he left in charge of... |
