New to the party and getting back into DIY audio after a very long break, Hi to everyone! I have I think been very fortunate to discover this forum and this thread in particular!
Having now aquired the relevant beasty's and spent some time breaking in and getting a feel for the unmodded sound, (and I must say being very impressed with how these sound in their raw state), I have done a couple of the very basic mods and yes, WOW, again!
As I first started reading the thread from the last page I soon realised that in order to get up to speed I would need some background info, so went back to page one, hence I have started with blue tack and felt. Whilst reading forward, I also worked backwards in order that I could see where the present state of the art is up to. In consequence I have some old ideas and some new ideas incorporated into my first efforts.
The port is currently about 85-90% closed with duct tape.
The reflex dot definitely helps the base extension for me.
Adding a roll of cotton at the rear of the stock pads to move my ears away from the drivers helped reduce harshness in the HF. So many thanks to all for the above suggestions.
Impressions after listening to the above is that I have been able to significantly improve over stock. Bass is extended, more punchy and clearer, Mids are more detailed and less muddy, presence and separation is more defined and HF is smoother. That's from listening to a mixture of Folk, Rock, Pop and Jazz.
My source unfortunately is in no way doing these justice, consisting of a mere Sony Playstation and the speaker out from a pair of Bose media speakers:) Even so, I am impressed with what I am hearing at present. An SSMH amp is on the building board and a Shigiaclone is in the wings. I am looking forward to the improvements...
Next on the list is to try and dampen the cup resonance more and to move on from the Blutac to Newplast modelling clay in the Baffle channels. Was it Dogwan who was wondering about the purpose of these channels? My own opinion, (Engineering background!) is that the webs that you see help stiffen the baffle. It's easier to mould thinner plastic I would think. I am looking forward to finding out how it went with the spray on absorber.
Regards to all
