Guest radeon_x1 Posted May 4, 2006 Posted May 4, 2006 Hi , just out of curiousity will the changing of the foam in a speaker change the overall soundiong of a speaker? I had heard the by changing the material the sound will actually changes. May i know what is the effect in changing of the foam in a speaker cabinet to something else change the sound? Can anyone enlighten me? Thanks
synthesis1624705793 Posted May 5, 2006 Posted May 5, 2006 Why don't you remove all the foam in your speaker and have a listen
Transworld Posted May 6, 2006 Posted May 6, 2006 Actually the purpose of the foam is to tune the tightness of the bass. Lesser foam will produce boomy bass and more will tightening up.
Guest radeon_x1 Posted May 8, 2006 Posted May 8, 2006 I had try remove the sponge and it sound very weird as in the bass sound very messy. My speaker since to sound bright.
MC_Hammer Posted May 8, 2006 Posted May 8, 2006 I always change the foam in the speakers to the egg crate foam (from Martin Electronics)...always sound better n cure most colouration problems in the cabinet !
Hardlok Posted May 8, 2006 Posted May 8, 2006 I had try remove the sponge and it sound very weird as in the bass sound very messy. My speaker since to sound bright. Removing the filling material completely, allows more direct reflections and re-reflections of sound within the cabinet (in the mids) which will contribute to the messy sound. Removing the filling also changes the volume of air in the cabinet, which results in different bass rolloff and power handling characteristics, as well as changes in resonances and diffraction effects that were to be addressed by the filling in the first place. Changing the material to another type (in terms of density, frequency absorption range, etc) on the other hand, may give better results. However, things are never so straightforward because when you change the effective surface area, density and absorption coefficient of the filling material, you will be mucking around with the parameters specifically designed for the cabinet and driver characteristics. Even if you get a "tighter" or less boomy sound, it may well be achieved at the expense of bass extension, or power handling, or uneven frequency response.

When I Open the speakercabinet...I normally don't just change the foam..infact the foam is the last n the less significant item within the cabinet My piorities : 1) Change Capacitors 2) Chnage the internal cables 3) Change the resistors 4) Change to better foam if there is too much cabinet colouration

I guess this is subjective.. Let's say u bought a Sonus Faber Armati, would u consider messing around with its internal component?

I will open up every pair of speakers I own whether it cost $250 or $25K..I won't call it messing around if you know wat you are in for ! 8) After modding more than 100 pairs of spks (lost count )....I can safely conclude that don't ever have the Naive thinking tat just becos a pair of speaker is a popular brand n $$$$$$ means it will definitely use the best material available in the mkt...be prepared to be very very surprised ! :'(

I'm interested in this topic :) I've already changed the Capacitors & internal cables of my speakers ;D ;D But I got sum1 to do it for me cos I really have no trust in myself in all this messing stuffs...
Genie Posted June 10, 2006 Posted June 10, 2006 May I know who I can approach for the changing of capacitors, resistors and cables in an old pair of speakers? Are there specialist shops around that provide such a service? ???
Transworld Posted June 21, 2006 Posted June 21, 2006 May I know who I can approach for the changing of capacitors, resistors and cables in an old pair of speakers? Are there specialist shops around that provide such a service? ??? You might need to find out the caps & resistor values in your spk X-over and source for the high-end version of it yourself. Some of the shops they will do it for you but you need to buy the components first. If you can't read the part numbers, you might want to seek help in Echoloft. Good luck.

I suppose SLT is the preferred hunting ground for the replacement components?

hifi_blues Posted June 26, 2006 Posted June 26, 2006 It depends if your speakers ported? If so then no. If not then replacing the fabric with insulation will make a difference. It could reduce the standing waves inside the cabinet. Make sure you remove the paper from the insulation and weigh the same amount for each speaker.

I had since change all the component of my crossover of higher grade and it sound pretty mellow and do not sound as harsh and less fatigue to listen to. Improvement is definitely more then just playing with IC or speaker cable.
