Lewis Sheppard Posted February 27, 2014 Share Posted February 27, 2014 So my mum thinks that if the speakers are quite heavy it shouldn't make a difference. Does it? Do I NEED a stand or can I do without? Link to comment
Deaf Cat Posted February 27, 2014 Share Posted February 27, 2014 As long as you think the glass cabinet is strong enough... why not? Stands, as would putting them on the carpet, may give a slightly different presentation to the music. Link to comment
Guidof Posted February 27, 2014 Share Posted February 27, 2014 My guess is that if you isolate the speakers from the cabinet (not couple them to it), you may get away with it. But I never tried a glass support. In any event, most "bookshelf" speakers tend to sound better not on shelves or cabinets but on proper stands. Regards, Guido F. For my system details, please see my profile. Thank you. Link to comment

Yeah I reckon so, I have heard it completely changes the sound or something, wondered if anyone else can elaborate? Link to comment

Yeah I gathered but I don't really have enough money to be buying stands at the moment. How would you isolate the speakers? Link to comment
Deaf Cat Posted February 27, 2014 Share Posted February 27, 2014 Blu-Tack, sorbothane, squash balls, innertube, rubber door mat, silicone, :-) anything squashy I think goes towards isolation, Brass / Steel speaker spikes I think couple rather than isolate, and probably not a good idea on glass ;-) Have a play. another area to investigate ;-) Link to comment
Guidof Posted February 27, 2014 Share Posted February 27, 2014 Yeah I gathered but I don't really have enough money to be buying stands at the moment. How would you isolate the speakers? For an inexpensive way to decouple (some) the speakers from the cabinet, buy 6 anti vibration pads available for 99 cents each at PexSupply.com and place 3 of these under each speaker. Can't go any cheaper than that. These will not be a perfect solution, but they will help. For my system details, please see my profile. Thank you. Link to comment

I'm just gonna try a load of different things tbh, hopefully work very well. Link to comment
PopPop Posted February 27, 2014 Share Posted February 27, 2014 I built these shelves with 1/4 inch glass and cantilevered the shelves out from the back on 1" square steel tubes. The amp and the CD on the middle shelf have a combined weight of 45 pounds, the DAC and the power supply weigh about 30 pounds. Glass is very strong if it is supported adequately. That I ask questions? I am more concerned about being stupid than looking like I might be. Link to comment

It's not really the weight mate, it's more about the vibrations from the speaker/bass. Thanks though, at least now I know it can hold it definitely. Link to comment

iago Posted February 28, 2014 Share Posted February 28, 2014 Do I NEED a stand or can I do without? If you need a stand depends mainly on the space between your shelf and the wall. Certain speakers sound better when they are placed at a distance from the back wall. You should find out the minimum distance first before deciding if you want stands.

Sam Lord Posted February 28, 2014 Share Posted February 28, 2014 Glass is a GREAT damping substance. If I had a heavy, strong glass platform I would *couple* my speakers to it. Or if I could afford it I would couple them vertically but allow them to wander at subsonic Hz horizontally using high quality bearings like Aurios. If I were to use Blu-tack for coupling I would keep it very thin (as you always should), which basically acts like glue. Just be sure the baffle of the speakers are flush with the edge of the glass or well in front of it. Never use soft materials like rubber feet under speakers, ever, unless they are so thin (like1/32") that they will not allow any detectable movement of the cabinets. It would simply allow the cabinets to oscillate, not good.

Sam Lord Posted February 28, 2014 Share Posted February 28, 2014 What you want to hear is not necessarily what you should hear. Guidof, if you are only repeating something useful, that the Lewis should use stands, that is generally true, you want to bring the speakers out into the room as iago suggested. But the heavy glass shelf should work well. Now it is certainly possible that the resonant frequency of that system of back-anchored, weighted glass will be in the audio range, but glass in nearly every case will be far better than metal or wood or MDF. How heavy are your speakers and how heavy is the cabinet? Do your speakers have ports in the back? If there are ports then you really should get them out enough for the ports to breathe. However that actually becomes an opportunity, because you can place very absorptive material like thick wool or sandbags behind the ports to break up the wall reflections from the ports. Finally a really cool option in case the speakers actually would be flanked by books: put the speaker baffles flush with the books. Bingo, instant near-infinite baffle with front diffraction problems solved. Since you asked, my system is in my signature below, the speakers are an unusual monitor and 2x sub combination on massive stands with essentially perfect time coherence: <2mm tweeter-to-woofer error and <5mm woofer-to-sub wavelaunch error for the centrally seated listener. It sounds very good.

PopPop Posted March 1, 2014 Share Posted March 1, 2014 Yes, MD208 that I bought from Hi Fi Sound about 5 years ago. It's sitting in a box at the moment because I replaced it with Primluna Dialogue amp that I think suits the Maggies better. I really like the MD tuner section and I'm torn between selling or just finding another place for it in my home. That I ask questions? I am more concerned about being stupid than looking like I might be. Link to comment

crisnee Posted March 1, 2014 Share Posted March 1, 2014 Lewis, how concerned are you with the sound quality of your system? If not too concerned then it doesn't really matter much how you place the speakers on the shelves. But if it is a major concern then you're thinking about it all wrong. Where and how you place the speakers in your room is probably the most important thing you can do re SQ (sound quality) once you have a minimally decent system. Whole books have been written on how to set up speakers in rooms so they sound the best they can. Chris Link to comment
