| Finally Learned: Subs serve much larger role than adding more low bass Or it the Swarm only effective scattered around the room? @mglik If your mains make bass, I'd place the Swarms to the side or rear of the room. They are only a foot square and if the driver is facing the wall (and the sub is only 2 inches or so... | |
| Moving away from inefficient/low impedance speaker in order to move to a Tube Amp @fjn04 How big is the room in which this speaker is being used? If you are planning a lower powered tube amp and need to fill a larger space, the Harbeths won’t do the job. They are 6 Ohms, and Sensitivity is rated 86dB, meaning their Efficiency ... | |
| Amp hum. Touching the amp or pre amp changes the volume of the hum. That isn't a tube. That's some sort of ground problem; apparently its affected by heat. Does it do it on all inputs to the preamp? Since its in the right channel only, power cords and... | |
| TL074 vs.TL084? @kakwu Generally speaking the older the opamp design, the less gain you can get out of it before it starts to have a 'sound'. Even with modern opamps the Gain Bandwidth Product they have makes it dicey asking for more than 20dB. With these older d... | |
| Finally Learned: Subs serve much larger role than adding more low bass Finally Learned: Subs serve much larger role than adding more low bass My GF commented on how the addition of the subs really helped out the tonal balance in the high end- how the system became more relaxed. | |
| ProAc Response 2: CJ CAV45, Cary SEI 300B, or Cary Rocket 88? @leahy back in the early 90s when that speaker was made we sold a lot of our M-60 amplifiers for use on them- it was the most popular speaker used with that amp at the time. That amp made/makes 60 watts. Unless you are really serious about low lev... | |
| Fancy Fuse for Regenerator? I'm seeking opinions if this is a great place because the benefits will go to all my equipment, or if it's a waste because the power is regenerated anyway. My prediction is that if you listen carefully you'll find no difference at all owing to... | |
| Suggestions for high efficiency speakers? Where are two Swarm subs positioned in relation to the CAL T-3's? One is placed against the wall (with the driver facing the wall) to my left. The other is behind me and to the right- it too has its driver facing the wall; in both cases to insu... | |
| Suggestions for high efficiency speakers? That was a bit elusive, yes. I tried to touch upon that using a sub setup the way I outlined as being my preference is a matter of having a different "design" goal - i.e.: high-passing the mains fairly high to a pair of subs, (the need for) symme... | |
| Dustcover Blues My problem is occuring just above the cutoff frequency. @mijostyn Filter theory says that the greater the filter slope, the greater the hump is prior to cutoff- and the closer to the cutoff frequency. A digital filter might behave differently (... | |
| Speakers for a Large Room (20’x37’) One other option, sort of off the beaten path is the Classic Audio Reproductions line. We've done ballrooms with the Classic Audio Loudspeakers T-1 and T-3. With that room size using those speakers I'd recommend 100 watts if you plan to crank i... | |
| A pitch too High! Why do you guys want me to buy a new Grado stylus. I'm was not suggesting any such thing. I misread the situation and had thought you got a different cartridge and thus solved the problem. Re-reading I see now that it was gauge instead. Eithe... | |
| Tube dampener questions I then purchased a 1960s d getter tube input/driver tube and the tube dampener became a moot point. The new tube sounded better and I don't feel the need to apply a dampener. Was I really hearing microphonics? I don't know but that tube is bac... | |
| RCA 9289 tube amplifiers I brought the amp up slow on a Variac and it passed sine wave. That's good! Don't keep running it until the power supply has been refurbished. Otherwise running it is a classic way that a failing filter capacitor causes a power transformer to ... | |
| Suggestions for high efficiency speakers? That's dangerously arrogant. You're not acknowledging the alternative, which is conspicuous in itself, and I doubt you've had a pair of symmetrically-to-the-mains placed horn subs or other efficient, large 6th order bandpass ditto (from a point o... |
