Wire rope cables work really well for hauling.

As my mum would say "You've made a silk purse out of a sows ear". Amazing skills you have.

I would appreciate thoughts and guidance. Would one need to fully line the speaker enclosure or can one strategically place a section of no-res mid-way on a panel. Example, If have a floor stander that is is approx. 40" tall and 18" deep, would there be any benefit in placing say a 20"x12" section of no-res on mid-way each side panel and back panel or would I need to fully cover the side panel (40"x18") before getting a benefit. I guess what I'm asking is do I need to cover the entire interior or just place smaller sections on each panel and baffle. Thanks!!!

My problem with the no rez I got with my NX Oticas is that is doesn’t want to stick very well- edges are coming up. Need a way to address this.

Danny, have you shipped to Australia? And if so is there a bulk amount that is more cost effective?

Would like to see the difference from both the new and old no rez. Perhaps a small book shelf ?

Hi. Can it be use to make sound absorbing panels to hang to walls ? Thank you !

Question Danny: that no rez has glue in the back? Thanks

I've recently been involved in a speaker upgrade. The speakers are TEAD Model 1. The speakers are quite large floor standers. They are made from 18mm baltic birch and were only lightly braised. We lined the cabinets with more 9mm baltic birch ply stuck in with Decidamp to CLD. This was then lined with acoustic foam and Mundorf Angel Hair. The loss of internal volume due to the extra plywood was not enough to significantly change the Q of the speaker. The upgrade took a good £6k speaker and turned it into something spectacular.

I lined the RP600Ms when I did the crossover upgrade and it was fantastic, I also did a pair of Klipsch Forte 1's where I did the bracing like he suggests at the 45° angles and lined with no res with great great results. Now if somebody could send in a forte one for the crossover upgrade that would be amazing!!!

Wow, that speaker seems huge, and the presence is very large.

Exciting! This video totally makes me want to upgrade another speaker. I’m patiently waiting for the right one to come out. 🔈👍🏻 great seeing a great product getting improved

Can you use No-Rez for acoustic treatment?

Hi Danny, I have not yet added No-Rez to my NX-Otica's. How many sheets of the new version would I need? I really like the black too!

If I use No-rez,do I have to put the poly-fill back in?

What ever happened to the Blackhole Damping Material

I am curious to see what upgrades Danny suggests to improve the Bully speaker.

Can it be used for accoustic treatment for a room?

Decades ago I puttered around with different cabinet designs. Came across an article from the (now long gone) Audio Amateur mag which suggested using auto under-coating to dampen the cabinet. Turned out to be a bad idea.

Have you ever look at a Hyperion 968s? Any comments or links?

Cool!

This is great news.

Great news, Danny! Quick question. If I line the inside of a speaker with new No Rez do I need to also put back the poly that I removed from the cabinet? Maybe fill the remaining space?

How did I not see it before?? Danny is the Ted Lasso of HiFi!!!!

Us in England haven't been very impressed with our team so far.

size M or L?

What about the polyfill that comes in speakers? After installing the no rez, can you get rid of the polyfill? Does it make a difference?

Hi Danny, back in the old days we used bitumous felt roofing panels to both mass load & deaden sound. The deadening resulted from the shear forces acting on the panel's many felt layers loosely bonded together by bitumen. My Malcolm Jones (of KEF & Falcon Acoustics) designed Tabor speakers (with Audax drive units) of 40+ years ago used 3/4" flooring grade board, 1/8" hardboard as a veneer, felt panels & fill to achieve a dead cabinet. As a result these 'bookshelf' speakers weigh 50lbs each. The Tabors are still in use every day. Cheers!

In a passive radiator speaker such as the Polk Monitor 7B which has only a tweeter and a midwoofer for active drivers, would there be a disadvantage to lining the entire cabinet with No-Rez, with respect to reducing the low bass response from the passive radiator? The acoustic crossover frequency was stated to be 60 Hz by Polk. This is also an entirely unbraced box. Thanks.

Congrats Danny and Co. If there's any concerns with the foam perishing over time - talk to the manufacturer about them increasing the level of anti oxidant additive in the PU foam formulation. Then it's a trade off of the extra foam cost (those additives are expensive) and the anticipated improvement in foam life. the Oxidation reaction is a function of heat and oxygen level (maybe also light and UV but that should be a minor or no concern inside a speaker, especially a sealed box.)

Foam quickly degrades in the tropical heat and humidity. So i end up using automotive sound insulation in my speakers.

It would be funny to buy one of Danny’s GR shirts and send it to him.

Would this help tighten the bass from an 8" car audio subwoofer in a ported box?

Nice update on the Hi-Po No Rez! Win win, re dimensionality. Remember the 80's borosilicate damping paste from Zalytron?

Quick question for you, hopefully it’s an easy one. I have a pair that I originally bought of Klipsh heresy II’s Would lining it with no Rez be a benefit,? And then maybe even a brace or two. Thanks for the videos Danny I watch them all

In an old project, where I converted a Vietnam War ammo box into a Bluetooth speaker, I used Butyl rubber flashing tape. I used to seal the inside of the box airtight and to line the panels. It is remarkably thick, heavy, and somewhat gooey. Do you think that it makes any sense to use such a product? If it were installed strategically underneath the No-Rez, might it increase the mass loading and therefore the damping?

News flash. Foam rots.

If you had used rock wool instead of foam Id be sold. Foam is just a horrible product, for human, animal and Earth health. Plus rock wool wont break down over time. Maybe do a head to head, rock wool vs foam.

Is NoRez available in Europe? Do you have a dealer?

great stuff. Nothing like having a buzz box for a speaker. once you hear the buzz reduced or eliminated tough to go back to a talking cabinet.

Do any commercial speakers use No-Rez?

Devious toad masquerading as honest.

I haven't found an equivalent in Europe yet with a combination of anti resonance and foam.

Got a pair of these for sale.... hit me up

I like what no rez does, and I've tweaked the formula a little bit in my audio lab using 1-way closed cell neoprene affixed to a 2mm sheet of rubber. Simply bond the closed cell side to the rubber liner and bond the rubber side directly to the speaker cabinet. Soft, lightweight insulation like dampening is finally a thing of the past

Every time I hear imperial measurements I die a little inside lol.

I had the same problem with the foam crumbling after some time from a similar product I bought years ago from Parts Express, I think it was called Sonic Barrier.

Dang, and I just completed my 357 ft.³ cabinets

First comment 💪 TY as always!

I've never liked speakercabinet's that aren't mirrored, it just tells me the producer tried cutting corners and cost.
