| are subwoofers anti-audiophile? Nandric writes:>The designer Joachim Gerhard (Virgo,Caldera,Medea) keep away from 'enything' below 40Hz in the mentioned loudspeakers. But for those that parsist on organ music he produced some subs...It's about trade-offs.At the same efficienc... | |
| are subwoofers anti-audiophile? The physics favor separate bass enclosures.The best locations for higher frequencies (as close as possible to the listener to maintain a higher ratio of direct sound to the reflections without being too close for the drivers to integrate correctly... | |
| Is it normal for the woofer to move in/out slowly 1. It's not abnormal2. It's only bad if it drives the woofers to their mechanical limits.If you really wanted you could hang a scope on your speaker terminals and see what's happening.1-1.5 volts peak is fine even for tweeters (That's what I get i... | |
| Setting Sub Crossover Freq >03-11-10: PtmconsultingI agree, you have to set the crossover point LOWER than the bottom of your regular speaker. Then adjust the integration using the sub's volume control. Don't forget to check the phase of the sub also.I disagree. You have... | |
| Best speakers for 15X14 ft room Prp2K writes:>I am seeking advise/recommendations from the collective knowlege base on speakers for a 15X14 listening room. I'm moving and can't use my large rear ported speakers in such a small area. The new speakers will need to be say a foot... | |
| "Tell the industry what you want" postingboard I want to license interesting designs for a small fee and build them. The doesn't constrain me to technically compromised designs which sell well in the market place, gets me more attractive furniture grade construction, can save tens of thousands... | |
| 4 ohm load vs 8 ohm load? What is prefered? 01-13-10: Drew_eckhardt>When you plan to use the amplifier for music instead of science experiments you should get peaks 3dB higher into a 4Ohm load than an 8Ohm load.Assuming equal efficiency.I think the big thing is to not worry as long as yo... | |
| 4 ohm load vs 8 ohm load? What is prefered? >01-12-10: RsfphilThe way I understand it is given the same sensitivity the amp would have to double down into 4 ohms for the 4 ohm speaker to play as loud as the 8 ohm speaker. The MA6500 almost gets there so it would be very close. I doubt if... | |
| 4 ohm load vs 8 ohm load? What is prefered? 01-12-10: Kijanki>With 4ohm you gain 15.7% of perceived loudness but loose almost 100% of damping factor (120 vs. 230). 1. FTC amplifier ratings are an over-reaction to the 1970s amplifier spec wars which have little bearing on actual music. A ... | |
| Is a Sub worth the bother? Rob_hughes writes:>Depends... what kind of music do you listen to? Most rock, pop, and jazz won't really benefit if your speakers will reproduce at least 40HzI've never heard a 2-way system which didn't benefit immensely from adding a sub-woofe... | |
| Bass reinforcement for very large room 12-22-09: Kijanki writes> Bipolar speakers don't make nodes in the room. Bipolar speakers most definitely stimulate room modes - I measured over 10dB peak around 70Hz in one room with a pair of Definitive BP8s.In the modal region conventional s... | |
| Bass reinforcement for very large room >My main system resides in the great room of our open-concept house - essentially a 30x30 open area (entryway, family room, dining room, kitchen) with 15' ceilings.Modal issues dominate the bass region for nearly all systems and with identical ... | |
| Anyone use the tweeter attenuation on Maggies? Wgallupe writes>Toe in will increase treble response at the listening position. Parallel to front wall will calm the treble a little. Also, try swapping speakers left to right so you can compare sound with tweeters "outside" vs "inside".Toeing ... | |
| Anyone use the tweeter attenuation on Maggies? >They are 34 inches from the back wall. If they were too close to the wall I would expect excessive bass.Dipoles don't work like that.Conventional speakers have more bass when located near walls because the reflections coming off the back side ... | |
| Upgrading Speaker Components >So if I have a pair of speakers with nice cabinets & want to swap the drivers out to something more upscale(better materials such as carbon fiber/silk)is it absolutely necessary to change crossover components.Yes.>Is there a guide or we... |
