And
The P17 starts rolling off at around 2K and the D27 at around 1k
So i plan to cross them over at around 2k...and i intend to design and execute the crossover by myself.. I am planning to put a second order section for the tweeter and a first order section for the lpf... I've tried simulatiing something in SPICE although wont be close to real system... can someone comment on the results... This is the crrossover i've been simulating...... |

Now in the spice simulation, if i reppace the simple load resistor (the Speaker) with a simple model of the speaker will the results be more predictible...?
If so does any one have a model ready which i can just drag and drop and change the values...!! Should be interesting...

I am planning a floorstander with Vifa TC18WG49 and D27TG0506. Still wondering whether to make it ported or sealed.
Ajju, did you buy the drivers from Shiva?
