Hy Brian, thankyou for your good question here, i thought choosing the tweeter was daunting
Ian we ain't started yet, everything now revolves around filtering, below No1 being the quickest & cheapest option i'm thinking to get started..
1\ 2-way 'discrete-active' populated or unpopulated(AliExpress) 'we need this board' driving TDA/TPA (dirt-cheap) Class-AB for HF then maybe class-D & higher power for woof.
*2\ 2-way passive with high grade components for HF filtering cheaper grade caps for LF is not going to be cheap allround whatever slope/order in band-pass. Software simulation 'we have none' myself & maybe incl Ian doesn't have the inclination or time yet to learn this or we have yet to discover an existing network from Troelsgroven then source parts etc - Ian i'm sure you said last year 'this is easy' just gooi numbers in somewhere then it all just happens 'automatically..' come again?
3\ I don't want to go further/digital in a Prestige/Excel purely analog build thread meaning option2 could take longer if we can't help ourselves..
further purchase DSP/Parametric 6-band preprogramed SHARC ADSP boards frm alixpres? primarily AES in but analog goes ADDA a queer thing to do should not be done, potluck if you also get SPDIF in here @24bt192kb
Maybe Prestige range is worthy of point*1 exactly what ATC SCMA range active non-DSP or Focal's model 11BE all discrete staging with filtering - do to their drivers..
