Firewall for Loudspeakers


The wait and the pre-order price were worth it ...

Do you practice witchcraft?

The improvement is global from the installation and is equivalent to an upgrade of electronic equipment, the gap exceeds the change of a good for an excellent cable .... !!

Firewall for Loudspeakers ... Daisy Chained

This is my 3rd report on these firewalls. This time upon LessLoss' claim, that more is better :)

Since I have bi-wiring loudspeakers, I needed 2 sets of firewalls to cover the double inputs of the speakers. I "cheated"on the bi-wiring, by running a single loudspeaker cable into a splitter at the loudspeaker inputs, before the firewalls arrived.

At first, I did not want to risk any sound quality, by adding this splitter between the firewalls and the speaker. After my fantastic experience with daisy chaining the firewalls for power, which ended in ordering a custom power distributor with "lots" of firewalls inside, I could not leave it like this and changed to daisy chained firewalls for loudspeakers as well. So my splitter went right into the speakers again and the firewalls could be daisy chained as single cables down to the speaker cables.

Wow, what a change. Again more of the same improvements, more presence and resolution and space and bass and less unwanted sibilance.

Get yourself a treat and get a second set of firewalls for loudspeakers. Maybe kick out the entire loudspeaker cable and replace it by as many firewalls as needed to reach your amp from the speakers ... Should try this myself :) My wife won't like the looks though :(

And another bravo to LessLoss for a C-MARC replacement of my normal loudspeaker cable splitter. It just did the same as all LessLoss solutions ... plenty more natural and organic, resolved, richer, ...

Now I am sure, I will replace the remaining loudspeaker cable as well !!!

Thanks so much Louis and team. You make me happy with my stereo!!!

Very pleased with everything I’ve recently added...

Combined with all the Firewall 64Xs, those two sets of Firewall for Loudspeakers have made for a substantial improvement in the sound.

Musicians sound closer - very much like they’re in the room.

Listening is more involving, engaging, and it has become easier to let go and relax into the flow of the music.

I am more frequently riveted by how natural the recordings sound now - the timing and tonality of instruments come through so beautifully!

Everything’s more coherent and just more believable.

This has been a worthy upgrade!

I had an audiophile and musician friend over this evening, and we listened together to assess the effect of my two biwired sets Firewall for Loudspeakers.

We listened to two tunes.

Johnny Hodges: Blues-A-Plenty (Verve):

Playing with, then without the Firewall for Loudspeakers.

W/out FWfLS:

Washed out, not as focused, less depth to the sound - things sound thinner, more diffuse and rather too bright.

There aren't as much overtones in the lows, making a piano seem more clangy sounding by comparison

Cannonball Adderley: Somethin’ Else (Blue Note):

Playing without, then adding back LL FWfLS:

With FWfLS:

There's more body, resonance, depth, more three dimensionally to the music; it is just less electronic sounding - everything feels more natural, like real instruments sound & less like reproduced instruments heard on a good audio system.

Timing and space seem improved with less overhang. For instance, a quickly played string bass has more woodenness to it, while intonation and incisiveness are maintained.

Hearing the plucked strings' pitch, the notes' decay trail off in volume just as they should.

(We remarked we are probably hearing everything with much cleaner sound and with better resolution even than what Rudy Van Gelder was getting as he listened over the monitors in his studio.)

The Firewalls for Loudspeakers are another HUGE success in my system!

This is a perfect example of how one thinks all the ‘noise’ has already been removed from the system, after the great success of the Firewalls for mains power, but with these new modules now added, yet further dramatic improvements have been achieved.

These improvements are along the same lines as with the power Firewalls, i.e. simply put, yet more clarity and realism.

The clear message is that, no matter how good you think that your system sounds, you simply don’t know what ‘noise’ is still there, degrading the SQ of the music, until it has been removed.

Thanks again for yet another remarkable product.

I installed your new Loudspeaker Firewalls on the treble and bass modules of my loudspeakers today and then had a first listen. I really wasn't expecting to hear an improvement because my high-end shotgun speaker cables are custom matched to my speakers. But I was pleasantly surprised and wondered if my ears were playing tricks on me. As good as my speaker cables are, with the Firewalls installed everything just sounds better and more realistic. Instruments and voices are more convincing in timbre and body, with noticeably better micro-dynamics.The sound stage is as large and holographic as before, but with a more natural, more cohesive presentation. I sat glued to my seat for hours, listening to my favorite CDs, hearing delightful subtleties in the recordings that I had not noticed before. It did not matter which CD I played, it sounded better and more real. For me the Loudspeaker Firewalls are keepers.

The Firewall for Loudspeakers after more than 250 active hours.

Please also see my first review from Oct 28, 2019.

Still totally happy with these firewalls on my loudspeakers. Anything I could have hoped for and lots more improvements!!

Actually the ongoing progress of the burn-in is not as bothering as I know from other recent changes, no matter of what kind they were. The 3D was sometimes flatter, the dynamics a little smaller, but no harshness at all. So it was always better than before the implementation and never really frustrating!!!

After a couple of weeks, the room turned impressively more airy and larger again. Transients are driving the scenery more than ever before. Less resonances also. It reminds me strongly of my previous electrostatic speakers in those aspects, just without the downsides :) And since then, it still got more of all.

Thanks, Louis and team, again and again and again :)

And for all others:
GO GET THE EARLY BIRD DEAL !!!

I have received the loudspeaker firewall and it has now played some 48 hours. There is a substantial improvement in timbre and fidelity. The sound has excellent transients, 3D perspective and conveys the ambiance of the recording venue very well.

The loudspeaker firewall is unique in the hifi world and a must have for all enthusiasts.

Congratuations for another excellent product.

Loudspeaker Firewall first impressions

After a long, but totally understandable waiting time, I received my double pack of the new loudspeaker firewalls for my bi-wiring speakers yesterday and am so happy now!

Even though, we all know, that parts like these, should have some burn-in time before making a final judgement; I would like to share my early impressions after only 20 hrs, because it is just so great.

The looks are very special with organic and technical looking parts combined. They feel and look like a valuable well made piece and to me seem smaller, that the close up pictures, we were able to see earlier.

Plugging in with a good tight grip of the connectors was so easy, because they are carrying the typical red/black markers.

The very first minutes already showed, that I was listening to a great improvement and this has gotten better with each hour so far. No initial harshness, but space and details were opening up more with time. So these are my findings so far:

-- Strongly improved control of sibilance. No sharp or almost metallic artefacts, that I before was hearing sometimes. It now feels like a believable and natural amount of sibilance.
-- Transients have a great match to the timbre of the source, which makes deciphering complex arrangements easier, especially with percussion.
-- All sources are richer in sound and display their building materials. Standup bass and piano now reveal their wooden bodies a lot more besides their strings. The timbres are more specific.
-- Voices are just gorgeous, now popping out a lot more, very clean but still increased richness.
-- Positioning of sources on the stage is more obvious. All seems to have more space and the speakers are not in the focus of the listening experience,
-- And finally the bass … again deeper and better controlled and more oomph and authority.

You might find my other reviews about my previous LessLoss items, the custom power distributor with firewall, the C-Marc power cable, or the bang for the buck Bindbreaker. This loudspeaker firewall is a definite no brainer to buy given the price … especially if you are not bothered with a bi-wire loudspeaker like me. It so much refines the previous purchases. Hard to imagine, but it still got better … definitely did and probably will even more with the burn-in.

Thanks so much Louis and LessLoss team for another wonderful product.


Next day:

The space just exploded and I was beamed into another universe.
Had it running at low level all night and morning until I came back from dog walk and shopping … And finally started listening not being in any way prepared … Just found all sound away from the loudspeakers way into the room and through the front wall. And everything so smooth still more dynamic and even more oomph bass … and finally a really big grin in my face :):):):)

Thank you sooooo much, Louis!

C-MARC bulk wire and cable; Firewall Module

Date Added: 10/22/2019 by Apirameth U.
Power distributor with integrated Firewall modules using C-MARC wire throughout.

The power distributor arrived a month ago. After full Burn-in for 3 weeks, yesterday I started to connect it to my main audio system, first impression is the noise floor level is much lower, the notes of each music instrument are very well seperated, the sound of intruments are more real.

The dynamics are simply excellent. I feel that the musicians, now, are playing with their soul. Most important thing is it makes me connect to many albums of music like never before. A very great and world class product.

Thank you to you and the LessLoss team for the professionalism and keep going with continuing to develop great products like this.

I am about 16 hours into listening to the New Speaker Firewalls. And my first reaction is "WOW"! The sound is more detailed than before and it is remarkably balanced across the audio spectrum. I am hearing the subtle and slight sub harmonic sounds that a singer will make in a performance. Something that you might observe in real life but certainly not consistently on a recording. There is just more of a sense of realism. It is quite intoxicating! Even Recordings that I didn't particularly care for before, I am rediscovering. To top it off I was impressed with the bass output of one of my recordings when I realized my sub-woofers had been accidently disconnected. I am speechless. Can't wait to see if these magical devices break in further!
