| what is purpose of home theater processor? 10-30-10: Chadnliz>Having said that if you have a system that excells at music it will easily perform well for movies but the reverse cant be had as easily.That's backwards.An excellent home theater system will produce 105dB SPL main channel an... | |
| Sealed vs Ported Subwoofers >The sealed sub absorbs the backwave of the open baffle driver. Not really a new idea.Not exactly.When you add a monopole and a dipole together you get a cardioid with 4.8dB directivity (versus 0dB for a monopole) which interacts better with ro... | |
| Sealed vs Ported Subwoofers A ported enclosure can be 3dB more efficient at the same size or play a quarter octave lower at the same efficiency.The same driver excursion will net you perhaps an extra 1/3 octave of extension with a ported speaker.You'll have higher excursion ... | |
| ss multi-ch. amps vs multi seperate amps any adv. >09-03-10: Longhornguy>Monoblocks are usually not the best answer in practical applications.>>Unless you have a dedicated 20 or 30 amp circuit in your power box, you will short out your 15 amp breaker with 5-7 monoblocks + tv + etc etc... | |
| Sealing ported enclosure to reduce boom >08-24-10: Ifsixwasnin9Great responses. Actually I stuffed the ports then I took out the woofer to see what was in the cabinet and the woofer is completely sectioned-off with pieces of foam! So I have to find out where the port is getting its b... | |
| Bi-amping + speaker crossovers = redundant? 08-24-10: Mhedges writes> There are commercial external crossovers for this exact purpose. I am using the now discontinued NHT X2 crossover to biamp my speakers. It is a good piece but would not be suitable for this application since it is real... | |
| How many 'listen outside of the box' design? >I don't know what they are called, exactly, but does anyone use regular cone speakers without enclosure? 'Open Baffle'? is that right? Sure. I built a pair of Orions designed by Siegfried Linkwitz.Everything good about panel speakers plus the ... | |
| what to do with my cat on my speaker grills Spray bottle and a sisal covered scratching post nearby (that feels better than speaker grill covers) | |
| Speaker cabinet made of real wood >06-08-10: TonywinscThe density of the cabinet walls is key to minimizing vibrations of the speaker cabinet.Denser cabinet walls won't do much; they need to be stiffer. With only a 3:1 difference in stiffness between MDF and hardwood you're goi... | |
| Best budget speakers for near-field/small space Milesandcoltrane writes:>I've also heard many great things about the Linkwitz Pluto. And since its available as a DIY I could save some bucks (though I have no experience whatsoever, so its a bit daunting).Apart from maximum output level (a 16c... | |
| Symptoms of damaged drivers / crossovers? If you're measuring across the speaker terminals, only a failed lowest frequency driver will show up as infinite resistance. | |
| Seeking "Crossover Networks For Dummies," please > "monotonically increasing directivity index"?> I assume that directivity increases with frequency, but I am unsure what is meant by "monotonic" in this context. Can you shed some light?Monotonic means that it never decreases along the way ... | |
| Seeking "Crossover Networks For Dummies," please Floyd Toole's _Sound Reproduction: The Acoustics and Psychoacoustics of Loudspeakers and Room_ is the best synopsis of 50+ years research into how human hearing interacts with loud speakers and rooms.It'll help you understand what good speaker des... | |
| Low Volumes >Do I need better speakers? Model 1s crossed my mind. Better amp? A Luxman 505u crossed my mind.A digital preamp with a decent loudness control would be ideal. Some form of equalization to increase the bottom end would be a step in the right di... | |
| are subwoofers anti-audiophile? >04-07-10: UnsoundNandric, Stereophile is fixated on 20-20K because that's the limit of the recording mediums available to us.CD is good down to .0002 Hz assuming you fit a full wave on a 70 minute CD.20Hz-20KHz is generally regarded as the lim... |
