Best buy bookshelf speaks...look at this: how could it sound?

Centvrion · 06:39 PM

I'm projecting these:

Woofer: Dayton DA175-8
Tweeter: Tymphany- Vifa DX25TG05-04

In closed box Qtc=0,707 , with "typical" damping (glass wool)

Crossover:
Hp: Cs=22uF; Lp=0,82mH ; Rs=8,2ohm
Lp: Cp=12uF; Ls= 1,5mH

Subwoofer Response (Low pass freq. circa 1300Hz)

Total cost will be around 350€...

Could anybody express an opinion? Critics?How could it sound?
Does anybody have experienced one of these drivers?

Looks OK from here...Ya did your homework, turning down the BIG difference of sensitivities 85Db vs. 92 Db woofer to tweeter. At 85 Db total sensitivity will be a big power "sucker"..with the roll-off down low your a candidate for a sub-woofer. A single 12" DVC should suffice. Mount the "satellites" up near ..say chest level on stands. Perhaps a 'plate amp' for the Sub & your good to go.

For anyone looking at this design: take the cabinet structure and volume, crossover net, but move that woofer up of at least 6cm!
