Prototyping of Final4
Sonion 38D1XJ
Series,
zobel,
taped vent
Resistor to taste(increase to reduce bass)
Knowles DWFK
Forced series
Zobel
10ohms resistor
Resistor to taste( to decrease fullrange)
No cross, no dampers
10mm tube
2.5mm ID for DWFK
0.5mm ID for woofer
Now for extra notice for the builders
When DWFK and sonion will be fullranged, you will see the bass boost from mids and the loss of overall bass strength.
Thats DWFK coupling and can make vocals warm and bright at same(V-shape)
So resisting DWFK is important.
10ohm is starting
Drivers are also easy to gather
Sonion 38D1XJ can be bought from taobao
Those who cannot get 38AJ007 from soundlink and use two yellow.
Review of sample
10ohm DWFK + Sonion woofer.
Over clear. Final 2 but bass energy shifted to subbass. Guitar plucks are done better by non ferrofluid driver and especially DWFK. The guitars are physical in chest when combined with Sonion 38D1XJ subbass reach.
More extended. And more airy
Right now.
I am using no zobel
