| DIY speaker isolation base for a wood floor Blueranger,Just using springs will be wobbly. If you are targeting 2-3hz resonant on the springs, then most higher frequencies will not be transmitted .. it flops. If you add dampening in parallel with the spring (ie sorbothane), then you can kee... | |
| Is grounding with RCA is safe? The statement that floating chassis from signal ground is always better is a simplistic view that is not always right. Ground hum is not the only form of noise (or distortion) that can be ground induced. That concept totally ignores signal induced... | |
| Difference in sound between copper and silver digital cables? pmboyd,You will notice that people are assigning the same characteristics w.r.t. sound that they experience with analog cables to digital cables. If you understand digital you will understand that makes no sense. That tells me they are assigning q... | |
| Difference in sound between copper and silver digital cables? For a digital cable? No. Heck no. Zip. Nada. Zilch.Construction can make big differences in noise, impedance, etc., but for a digital cable for audio if properly constructed silver or copper will make 0 difference. Emphasis on proper construction ... | |
| THD In Light Bulbs If you are not using a dimmer, then I would not get too worried. It's just another small switching power supply on your AC line, and odds are you already have quite a few (all those USB chargers, and they can be worse).If you have a dimmer, then y... | |
| How can we hear the difference in cables in a bad room? When reading or similar visual work, you eye uses high speed movements called saccades to change the visual focus point. When reading the movements are small but fast and regular. Most of the body of work on this was done in the 90s, but re-emerge... | |
| DIY speaker isolation base for a wood floor If you have large diameter springs and do not overly compress them, you don't need conical spings. Conical springs have better stability the you can make one layer sit within another, but you shouldn't be compressing them that much. It is a bit ha... | |
| How can we hear the difference in cables in a bad room? Extraocular which controls eye positioning. The flickering causes issues with eye positioning. | |
| DIY speaker isolation base for a wood floor 6) The one where you get creative and figure out a way to have the springs and sorbothane between the two slabs at the same time ... or maybe the springs and a stack of lightly compressed cork. That way you get isolation and dampening.Which spring... | |
| Does raising speaker cables off the floor really make a big difference? Carpets are often made of one of those "fancy" dielectrics, i.e. polypropylene, and polyethylene, and because it is a open weave, would be similar to foamed polyethylene and foamed polypropylene, which are the best dielectrics for cable w.r.t. low... | |
| Why go out??? A large portion of the U.S. projector base is still 2K digital, about 60% I think is 4K. There are some really awful early Barco projectors out there still with horrible contrast ratio. They would all be 16:9, but the cheap theatres will not have ... | |
| DIY speaker isolation base for a wood floor Hey bdp24,Do you have experience with ISODAMP. We used some for a project a while back, but my colleague was working on that and I did not have enough time for "info-osmosis". I think the foams are quite interesting, and the availability is good. ... | |
| DIY speaker isolation base for a wood floor blueranger,I am assuming each granite slab is about 25lbs, and the sorbathane is between them, so assume a 100lb total load.georgehifi posted a link above to an Ebay seller. They sell 2.5" diameter disks of 70, 50 and 30 hardness. My rough calcs s... | |
| DIY speaker isolation base for a wood floor Wood floor. Assume somewhat springy? ... then usually better to isolate.Neoprene rubber of that surface area likely provides next to no isolation in the bass frequencies, and probably not much absorption. It is too stiff.I expect the cork does not... | |
| Sound treatment I really like the accent products. The Strata comes in a wide range of color. I will be interested in your feedback. |
