OK, so I have a few projects I working presently.
One is a pair of older furniture boxes that are approximtely 6 square (cubic?) feet and that will hold 15s, compression drivers and horn lenzes.
Anyway, after I'm done I assume the weight will be over 100lbs each.
Therefore, I'm considering using roller casters so the boxes can be moved from place to place for house cleaning, etc.
I've done this before with other cabnets and it seems like a good idea.
Does this impact bass performance?
Thx...
My speakers weigh in at closer to 300lbs ea. and I keep them on casters. Using CLIO, I can measure extremely subtle changes to the bass between sitting on casters and spiking them, but the difference isn't particularly audible... but then I am not a hundred dollar a foot cable guy either.

Considering how much easier it makes getting the room placement just right I think the benefits outweight and issues from the casters. Spikes are a real PITA in comparison especially with heavy cabinets.

...I read an article in a publication titled, Home Theater. I beleive it is the successor to Stereo Review.
Anyway, they conducted a blind test of audiofiles using (1) standard speaker cable, and (2) the $100 per foot speaker cable.
Apparently, about 70% said the $100 per foot cable sounded better!
I would not buy this stuff but apparently, the test results were based on a study that showed statistical significance!
The magazine also ran ads for the cable, so I assume it may be bogus???
I think there's already a fairly new thread on speaker wires, it'd be nice not to bring that potential flame war material to this thread. I'm not voting either way, but that wire discussion has gotten toxic in the past and THIS discussion is about casters on the souls of their feet. That high end wire discussion is here http://audioheritage.org/vbulletin/s...ad.php?t=18616
FWIW - over the last few weeks I've built caster wheeled "plinths" for my two pairs of speakers.
They sure help me get my speakers just where I want them!
Those 4341s are bit tough to shift into place on carpet without them!

Additional investments in SPIKES can be perfomed.Originally Posted by Mr. Widget

The remark on CLIO made me responding.
OK, I'm stumped. What are spikes? Are these the threaded adjustible feet that are commonly found on washing machines?
this stuff is spoken of:
cheers,

Spikes are hard and have a special form. Something like this, there is a great variety in the market:

I do not use spikes, for example my TT is attached to the wall by a rock solid board (no traffic outside).

My A7s as well as JBL 4647 based econowaves are both on rollers. Lot easier to move around, no loss of bass noted. These speakers are heavy,
mileage may vary with lighter bookshelf sized models. Rollers are too cool. Prevents a lot of banged up corners on speakers approaching 200 lbs as well.
Harbor freight has 1000 lbs furniture movers, I think were 14.99 a piece.
Avatar shows the A7s in my old house, where they set on the floor, all my "plus sized " speakers are now on rollers.

Greetings, All,
So, what size wheels are you all using for your casters? I would guess you have to choose, depending on load ratings, eh? Good idea, and one I'll explore soon, me thinks. Take care, and God Bless!
Every Good Wish,
Doc
The only thing that can never be taken away from you, is your honor. Cherish it, in yourself, and in others.
I have used roller casters for moving my 4345 clones.
Make sure they are rated for the load. Make sure your floor is flat otherwise it will rock and that is bad.
Depending on what your floor is constructed from it will make a difference to the bass (3 inches off the floor is 3 inches of air space).
In theory the box being on the floor will load more room gain if you care to model it. It will also alter any apparent baffle diffraction because the sound waves can travel under and over the box. Depending on your room this might be a good or a bad thing.
The lateral position of the boxes to the rear and side wall is going to have more impact on you bass. If you raise the box 6 inches you will definately hear a difference.. At least the roller casters give you the benefit of trying different positions. I found that very useful.
I think height adjustable spikes are a better alternative.
Ian
Rollers should make no difference if they are up to the task of supporting the speaker, don't allow it to rock because of tolerances in the axles or bearings. The height difference may be noted if it changed the FR because you are now on a slightly different listening axis.
Agree re the floor being flat.
I would like to see your modelling of a speaker in room on the floor vs one 75mm higher as the wavelengths are too long at LF for it to make a difference.
Diffraction? Lets say I'm sceptical without some empirical support.
Heather
Is that a Poang from Ikea I see there?
Out.
To the gentlemen from Australia: Put a bloody skirt on.
On the dolly I mean.
On the "four-wheeled truck with casters" dolly, not that dolly.
Preferably make it a removable one.
No, I can't see into your rooms.
Out.
