Subwoofer vibration foot isolators????

For my REL Britannia B1, I have custom-made (taller, more narrow width) Black Diamond Racing Pucks with the right threading to replace the stock (plastic feet). I then have the B1 on an Adona AV45AS amp stand. This puts the front-firing driver at a good height and also allows the port on the bottom of the sub room to breath. The bass is very clean, not muddy and (has been measured) goes all the way down to the lowest frequency possible with this sub. When deep bass notes occur, they are clean, fast, super-deep and have all the impact desired. There is no shortage of bass in the approach you are looking at; here when the bass impact is felt, it is via acoustical transmission, not physical output & interaction as Kr4 notes above. FWIW...

It sounds good to me and your B1 build is like the SVS PB13Ultra being front firing & 3 ports underneath driver.....THX alot.....I might go your root.....Is there a paticular model B.D puck you have and exact height????? Would the Adona stand hold a 155lb sub???? LOL ..Let me know & THX

Bacardi,

Right now on this site is a pair of Sistrum Sp101 adjustable platforms for sale. A Sistrum Sp 1 and APCD discs would work well also. I use SP101's under each of my James EMB subs and one each under my mono pair of amps. These are not isolation devices because there is no such thing as isolation. These platforms will allow for the collection of resonace to be redirected to the higher mass of the floor. The speed of bass will be much better with more detail and punch. Now that you can really hear your sub for the first time you will be able to better match the wave launch of your mains. This match will provide you with even better intergration into the mid bass and mid range make both more clear and resolute. Any speaker cabinet itself is a passive radiator. If this radiant resonant energy is not directed to ground away from the driver and the cabinet itself... it will self perpetuate. The speaker amp will amplify unneeded excess mud held and stored on so called isolation devices. I am a dealer..Tom

To theaudiotweak:

Do the APCD discs(3) go under the Sistrum Stand???? Will that be optimal improvement? What can be placed under my sub or ontop of the Sistrum stand to protect from scratches or scuffs???? My sub is the piano gloss black.

Bacardi,

You put the APCD discs on the top points those that will engage the bottom of your sub. For maximum grip and launch I elected not to use the discs on my subs, also piano black. I don't look at their bottoms. My subs bottoms that is. Tom
