Loudspeaker Upgrades
loudspeaker modification loudspeaker parts and repairs crossover components

Our order portfolio is currently full until january 2022. We look forward to receiving new orders after that date. We thank you for your understanding.

Like many things, the loudspeaker world hasn't stood still. Due to increasingly better measuring techniques and insight, new materials and applications, more refined products appear on the market; tg-acoustics continuously follows these evolutions and offers you the possibility to make use of them in your existing loudspeakers. An upgrade or modification can consist of the replacement of electrical components such as resistors, inductors or capacitors. But also alterations to the dampingplan and the mechanical properties of the loudspeaker cabinet can result in less colouration and better integration with the room acoustics. The end result is better definition, a more spacious image, more fine detail and a calmer presentation of the musical content. You also have the possibility to fine-tune the existing loudspeaker to the rest of the hifi-system and your own personal taste.

One of the possibilities of a loudspeaker upgrade is a total revision of your loudspeakers. This consists of a complete analysis of the loudspeakers from head to toe, followed by an inspection report with the various options that could be done and a corresponding price indication - a sort of health report for your loudspeakers! If you feel confident to modify loudspeakers yourself, I also can supply the individual parts such as loudspeaker drivers, crossover components, internal-wiring and accessories on request. Just send me an e-mail and I'll be happy to make you a quotation. After a professional treatment of your loudspeakers by tg-acoustics you will be guaranteed a renewed musical enjoyment from your loudspeaker system! Read what our customers have to say:

"Now that the loudspeakers have been playing for a while, the sound has opened up nicely. The detailing is great, I hear things on, for example, live records that I first did not hear. You can literally hear what the audience is calling or doing. Thanks from a satisfied customer." (Jaap - The Netherlands - filter upgrade Thiel CS3.5)

"First of all, thank you for the fantastic work you have done. My listening pleasure has received a huge boost. This is the result I hoped for. It is as if every instrument has been given more space and detail. The overall sound has become much calmer and more spacious, with each instrument much easier to place. The low end has become nicely tight and controlled, the midrange is more open and the treble is wonderfully sparkling. I am very satisfied, you saved me a huge search for new speakers. I also followed your advice regarding loudspeaker placement and have now found the optimal position for me. I can now get many more years out of my KEFs!" (Henk - Appingedam, The Netherlands - filter upgrade KEF IQ7SE)

"Yesterday I finally got round to finishing the AN-E's. And I must say, the first listening impression (even though not run in) is really fantastic!! I could not have dreamed this result, it exceeds my wildest expectations! Although I have of course improved several things (damping material, internal cabling and purchase of the original AN stands), in my opinion your beautifully built crossovers do by far the most. Thank you for this, but also for your expert advice and correct treatment, top class Tony!" (Jan - Leeuwarden, The Netherlands - filter upgrade Audio Note AN/E)

"I am in the heaven! Wonderful, you made a wonderful new interpretation of these Cabasse loudspeakers. The soul is kept but they have greatly improved. Once more thank you, you have made exactly what I wanted. Thank you. Thank you. Thank you." (Michel - Colombes, France - upgrade Cabasse Brigantin V)

"Crossovers arrived safely yesterday and I installed them this morning. They sound fantastic. The fluffle sound has completely disappeared and as you said the top end is a bit brighter. From Dave Edmunds to Mozart, they sound sublime. They are sounding as they should again. One very happy customer. Thank you so much." (Tony - Stroud, United Kingdom - filter upgrade Leak 2060)

"Here are my findings after the upgrade: The treble is nicer, no sharp edges anymore at high volumes. More air between the instruments, positioning is better. Acoustics of the recording venue are more perceptible. Hear more wood with double bass and strings. Vocals are more in the foreground, closer. Everything beautifully present and I hear more than I have heard before. More body in the bass. You understand, I'm very happy with the result." "I don't want to hold back my listener friend / bass-player's response: he thinks the improvements in the sound are impressive." (Remmert - Purmerend, The Netherlands - filter revision and upgrade MC Systems M3)

"The upgrade of the crossovers can clearly be heard. They have become totally different speakers, in a positive sense! On some recordings certain instruments, to which I previously did not pay attention, are now noticable. It's like when you put on glasses for farsightedness: suddenly you can see details in the distance that you suspected were there but just couldn't see very well. But the most important is the improvement in the midrange. Certain rock-music was previously just not fun to listen to (even with other speakers), a specific frequency was shrill and caused pressure on the ears ...... now everything is much more balanced with more homogeneity. I am amazed every day when I hear details that were previously not noticable. Cymbals and hi-hats now have much more definition and detail while before they were not even recognizable on recordings as such. The bass also has a lot more definition, Marcus Miller is simply playing in the living room! All in all I am very happy with the upgrade. Thanks again for that." (Paul - Amersfoort, The Netherlands - upgrade Usher BE10)
