| How much heat from a tube amplifier? Mine is at least 50 open in the back and 95% open in the front assuming the door is removed which takes about the same effort as removing a grill cover. I would have reasonable clearance on the sides as well.All kinds of cabinets but thanks for cl... | |
| Loudspeaker Cross-Overs and the Recording Arts IMO, there is a another factor that also effects the fidelity of the final mix. Recording engineers want the final mix to sound best over the playback system that it is most likely going to be heard. Hence newer pop recordings have lots of extra e... | |
| How much heat from a tube amplifier? I've installed a myriad of systems into cabinets and IME, you will need to get a couple of whisper type fans to exhaust the heat for any type of tube power amp. You will need one fan to exhaust the heat from the top of the cabinet. If you cut out ... | |
| Tube amp heat questions... FWIU, the following points all have an impact on either the WPC and/or the heat generated.~The class of operation (single ended, push pull).~The type and configuration of the output tubes (triode, tetrode, ultra linear or pentode). ~The number of ... | |
| Question of the day for speaker guru's. Parallel o Doubling the wattage is a 3db increase. In theory two of the same drivers wired in parallel will get you a 6db increase. Two of the same wired in series is 0db gain.In practice there are many things that will move the number around a db or two suc... | |
| Question of the day for speaker guru's. Parallel o Stacking two identical speakers, with the upper being inverted, gained some popularity in the 70's. You do gain about 6db in (effective) efficiency. In practice though it does present some challenges. First, the amp is presented a much lower imped... | |
| An interesting experiment Very interesting experiment but how do you explain tube preamps that use a cathode follower as the last stage? Their output impedance is comparable to SS but still have, IMO, all the best attributes of tube's. | |
| Balanced power amp and subwoofer connection. So is it a MJ acoustics sub? What model? Also which Pass? | |
| Damaged B&W 6 1/2 It's nice to think that each product was so carefully thought out that it required its own set of custom drivers, but from a business standpoint, why make a different driver for your $800 speakers (CDM 2SEs) than for your $1200 (CDM 1SE) speakers?... | |
| Corner bass traps on top of subwoofers. Thoughts? IIUC, in general bass traps are designed to lesson bass peaks at certain frequencies that are a result of trying to reproduce sound waves that are to large to fit in the room. These peaks tend to be in the same location in the room which is why th... | |
| Does Shelved Bass Help With 3D Effect? I too do not fully understand what shelved bass is but since I have heard systems that have a large 3D soundstage with and without great bass, IMO, the two are not related. | |
| KAV-280P & TURNTABLE IIUC, S3 is a line level input. Your Krell does not have a built in dedicated phono preamp so you will need to add a one between the TT and the Krell. | |
| Crystal Disc IMO, the XRCD and there newer variants are some of the best CD's out there in terms of recording quality. However, the limiting factor will always be the CD playback standards. Hi rez download or SACD are both superior to any CD based playback sys... | |
| Does Shelved Bass Help With 3D Effect? IMO, No. I can swap out a pair of tubes that improves the bass in my system and lose nearly all of my 3D. So in my system it does not have anything to do with the bass presentation. | |
| why no sound from subwoofer? What impedance does the woofer read? |
