Our take on the IsoAcoustics ISO-L8R155 Monitor Stands

If you're investing in a nice pair of monitors, why not invest in the stands that ensure their optimal performance?

Make your desktop monitors sound their best

If you're investing in a nice pair of monitors, why not invest in the stands that ensure their optimal performance?

This pair of IsoAcoustics ISO-L8R155 monitor stands employ the same principles as the best professional studios to simulate speaker "flotation." Thanks to a patented design, the IsoAcoustics stands eliminate the transfer of energy from your speakers to surrounding surfaces, which means you'll hear clean, accurate sound with every listen.

Full tilt boogie

IsoAcoustics makes sure you can aim your speakers for the best possible sound. Each stand comes with two pairs of inserts, two lengths of tubing, and two isolators (one bottom and one top). Choose the right tube length for your workspace and raise your speaker to the appropriate height, either 3" or 8" high, to avoid sound reflection off of adjacent surfaces. Use a combination of the included inserts to get the perfect tilt up or down so that your speakers' tweeters are pointed directly at your ears. The included isolators measure 6" wide by 7-1/2" deep to accommodate speakers at least 6" wide. Use IsoAcoustics' size calculator to confirm these are the right stands for your speakers, or if you have particular speakers in mind, check out IsoAcoustics' reference chart.

Praise for the IsoAcoustics speaker stands from Audiostream

"If you use desktop speakers, you owe it to them, to your ears, and to your music to try the IsoAcoustic speaker stands. If you are currently not using anything, they will elevate the musicality of your speakers by far more than inches, providing greater resolution, improved bass response, and a more focused sound image. They will in short make your speakers more enjoyable to listen to and that is more than worth the price of admission."

Great product. This is my first pair of monitor stands. I formally had my monitors directly on my hardwood desk. I use a pair of Yamaha HS5s with a Focusrite Scarlett 2i2 USB interface.

Excellent quality!



Get better imaging and focus

Jack H from Midway City, CA on 6/12/2017

Crutchfield Customer Review (What's this?)

These stands are very well made and they will work wonders when placing your monitors on a desktop I only gave it 4 stars in my setup because the 8" tubes place the speakers way above my ear level and the 3" tubes are putting the tweeters about two inch's below ear level when I'm seated straight up.If you have a set of speakers on a desk top you will not hear your speakers at there best without a good set of stands like these.

Pros: Have a set of PSB Imagine XB setting on top of pair IsoAcoustic L8R155 Monitor stands on top of my computer desk running a NAD 3020 to the PSB Monitors this is truly a fantastic setup.

Cons: Cannot get the tweeters to ear level using the supplied 3" or 8" tubes I believe that 5" tubes would get me to the height where the tweeters would be at ear level for my setup

Better definition, more reliable mixes

Jim from Knoxville, TN on 11/7/2016

Crutchfield Customer Review (What's this?)

These were easy to put together, quite sold, and pretty versatile for my setup. I bought these based on positive reviews I saw on them, and I have to say they are a great investment. they get the monitors properly at ear level, so I an hear them better, but what I didn't expect and love about them, was that the placement of sounds in the stereo field was better, and they took away all of the cloudiness in the midbass area. They initially seemed to have less bass, but what is there is much better defined. I did a mix and put it in my car system, and what I heard was much closer to what my monitors revealed, so my mixes will be more reliable. Great investment for my system. As always, Crutchfield delivers on time, with no issues.

Pros: Lot of bang for the buck, these things really make a difference.

Cons: Can't really say they didn't deliver more than I expected,

JimS from Boynton Beach, FL on 8/2/2016

Crutchfield Customer Review (What's this?)

These stands are very nice. Very hard to find decent stands for floor speakers, let alone find really good ones. Highly recommended.

Pros: Very well made. Raise speakers off the floor and give them platform that isolates them from the floor.

Cons: None

Excellent stands

Andrew from Rocky Hill, CT on 5/8/2016

Crutchfield Customer Review (What's this?)

Exactly as advertised.

Pros: Really opens up the sound and brings the speaker to life.


New speaker stands

Golfdrake from California on 1/13/2016

Crutchfield Customer Review (What's this?)

The stands are great. I should have bought the largest pair for my speakers. The mid sized pair are a little unstable on carpet but are working great. A huge improvement in sound quality.

Pros: Huge improvement on sound quality.

Cons: Should have bought the large set for my speakers.

Crutchfield Customer Review (What's this?)

Never had monitor stands and what a difference

Pros: Everything

Cons: Nothing

Like a new speaker!

MikeD from Connecticut on 7/7/2015

Crutchfield Customer Review (What's this?)

I have been listening to these speakers for some time, but until I put IsoAcoustics ISO-L8R155 Monitor Stands under them, I don't think I ever really heard them! The whole sound was tighter, especially the bass. There was more "air" between the instruments and voices. Outstanding product, very well made. Don't waste your money on more expensive isolation devices, these are all you need.

Pros: Excellent isolation, sturdy, well made.

Cons: None

They're just Right...

GeneZ from Georgia on 2/1/2015

Crutchfield Customer Review (What's this?)

This was not my first pair of IsoAcoutics stands. For over a year I had been using its baby brother. I had been using the ISO-L8R130's for my various audiophile smaller monitor speakers for my nearfield desktop listening. I recently got the ISO-L8R155's for my new larger audiophile speakers. As always... clean solid bass, and they work to help lock in the sound. Isolation from the desk is vitally important in extracting the best sound from speakers. The more the speaker's potential, the better these stands will allow them to shine.

Pros: They just make themselves right at home. This is what they are supposed to do. And, they do.

Cons: None really.

Does what its supposed to do.

adeep from New Jersey on 11/6/2014

Needed something reasonably attractive to raise my bookshelf speakers and decouple them from the cabinet they were on. It's all good.




Hands-on research

Product Research


Overview: The IsoAcoustics ISO-L8R ("isolator") speaker stands are designed to raise your speakers or studio monitors off of the tabletop or floor and angle them toward your ears. The stands have a unique floating design which isolates and decouples the speaker from the mounting surface to eliminate acoustic distortion. The ISO-L8R155s are black in color, and include the parts for 14 different combinations of height and tilt for optimal placement and listening positions.

Note: This package includes a pair of speaker stands.

Application: The ISO-L8R155 Studio Monitor stands are designed for medium-sized studio monitors, bookshelf, and desktop speakers. They should be used with speakers with dimensions greater than 6" wide and 7.5" deep, and weighing up to 30 pounds each.

PIF Principles: IsoAcoustics ISO-L8R stands are designed to support the PIF Principles of acoustic design:

  • Placement: The proximity to adjacent and nearby surfaces. The stands raise the speakers off the supporting surface and away from adjacent surfaces to reduce reflections.
  • Isolation: The stands decouple the speakers from the supporting surface to reduce the energy from exciting other objects. The speaker is allowed for float independently.
  • Focus: By raising and tilting the speakers, the stands create an ideal listening position. The speakers should be tilted to the listeners ear level, and positioned to form an equilateral triangle from the speakers to the listener.

Height/Angle Adjustment: Two lengths of tubing, plus two sets of tube inserts, are included to allow you to adjust the height and angle of the speakers. The rigid steel riser tubes are approximately 5/8" in diameter and come in 3" and 8" lengths. The short tubes should be used for larger speakers, and the long tubes for smaller speakers. The high-density plastic inserts are placed in the ends of the riser tubes to tilt the speakers up to a maximum of 6.5°. The inserts are placed in the rear risers to create a downward tilt or in the front risers for an upward tilt. You can use the short or tall inserts, or both, to obtain the optimal listening angle. The stands can be configured to multiple combinations of heights and angles, from a minimum height of 4.875" (short risers with no inserts used) to a maximum of 9.625" (long risers with both inserts).

Isolator Sections: The stand consists of top and bottom isolator sections, made of high-density plastic, with high-modulus co-polymer isolators on each corner. The combination of isolators and steel tubes significantly absorbs and dissipates the energy coming from the speakers so that it does not travel to the mounting surface. This allows the speaker to "float" independently, eliminating acoustic distortion. Both the base and upper isolator sections are 6.112" wide and 7.49" deep.
