| Risk using amp Wattage than speaker rating? 08-23-12: Cjl >The wattage rating is the maximum wattage a speaker can handle before they burn out, and has nothing to do with the Fidelity limit per wattage limit!To be pedantic it's a thermal limit if you feed the speaker pink noise (equal po... | |
| DIY high end speakers? While I built and own a set of Linkwitz Orions and am rebuilding nicer cabinets in the Orion-4 style with solid lumber curly maple baffles, Gabon ebony trim, and zebra wood sides (they will be _much_ prettier than any of the following designs) I'd... | |
| Cap life span? >Tntate (Threads | Answers | This Thread)>Cap life span?On a tight budget. Looking at older amps and need to know if capacitors have a set lifespan. How would I know if they need replacing?Get some big power resistors which can be wired in p... | |
| Cap life span? >08-06-12: Reb1208>When talk of replacing electrolytic caps comes up on this and other forums. Most people are concerned with the larger can style caps found in amps and preamps. Those are generally (output capacitors on an OTL tube amp woul... | |
| Cap life span? 08-06-12: Rodman99999>If you look at the datasheets of aluminum electrolytic caps; you'll find that their expected life spans are noted in hours, at a certain temperature.Right. That's usually 85 degrees C but can be 105 degrees C which is hott... | |
| bipoles/dipoles for music... 1) Dipoles and bipoles are extremely different things. An acoustically small dipole has 4.8dB of directivity which means it's radiating 1/3 the total power of an omnipole for a given on-axis SPL. A bipole tries to approximate a monopole with 0dB o... | |
| rear firing tweeters.... >I have a pair of old Snells with rear firing tweeters...just curious why we don't see this configuration more today ? Phase issues? Placement problems? Engineering issues?We're trying for uniform polar response which is already much broader th... | |
| Subwoofer hook up 07-10-12: Secretguy>Thanks, but no one has answered the question. WILL the xover setting on the sub filter the low frequencies going to the Maggies IF I wire them as described?Some and probably not how you want. The speaker level filters are no... | |
| Subwoofer hook up >07-10-12: Ryriken>You can run them full range, just use the pre-amp out to your sub inputs. I think this will work, Try to experment with cross over and volume control too.You generally don't want to run speakers full-range with the sub sin... | |
| Best Active Crossovers? FWIW, Both my main and bed-room systems are actively tri-amplified and I've heard other successful and unsuccessful realizations. I was quite happy to leverage Siegfried Linkwitz's (as in Linkwitz-Riley) design work which just left the soldering t... | |
| 2-Way 3-Way Debate >I am fairly new here and would imagine that this debate has taken place previously. Sorry if I don't have time to scroll back through all the speaker topics but can a 2- way spkr really provide the definition of a 3-way? If the bass/ mid drive... | |
| frequency range for instrument vs speaker 06-23-12: Stringreen>Richard himself helped me with my setup and told me that the goal was NOT to get a flat frequency response...just s pleasing one. That's an over-simplification.As an engineer I have built speakers with acoustically small dr... | |
| frequency range for instrument vs speaker 06-22-12: Onhwy61>I think Frogman is correct, but it should be put into perspective. Suppose you were an audiophile with limited funds. Would you be better off pursuing bass response down to 20Hz, or compromise at 50Hz (with room reinforcement)... | |

| frequency range for instrument vs speaker Other points about low frequency extension are that1) It's not a brick-wall. Extension to 50Hz generally means that output is at least 3dB down at that point with a noticeable 1dB of drop up much higher like at 80Hz.2) The effects are worse than t... |
