Your are seeing the fruits of a good X-over upgrade. Depth perception in the overall soundstage is what people chase after. Now tell us more about whats “different” post the upgrade.
2 months ago, I set some design goals for my loudspeakers as doing a piece meal approach was not taking me anywhere both measured results or listening experience wise. The design goals are,
- perfect step response at a mic positionof 50" in-between my midrange and compression driver.
- perfect squarewave and impulse response at the above mic position.
- apply B&K house curve to allow proper spectral decay from low to high frequency.
- a decent group delay
- minimum phase speaker system
After 2+ years of toil and in the past 2 months of design iterations, simulations, measurements and fine tuning could achieve atleast 98% of what I set out to achieve. This itself gave me a sense of fullness and contentment.
Listening wise, I can now sit any location in my room and still get center image focus from that particular sitting position. The entire listening room is a sweet spot now and not the one sitting in-between the speakers. This gives me lots of listening flexibility.
The perfect Square wave response indicates that all frequencies arrive at the same level and the same time at my mic position in time domain. The perfect step response indicates that all drivers are well integrated with each other again in time domain. Though I am not 100% satisfied with the minimum phase, but again that's a fix for some other time. Impulse response anomalies indicate frequency levels, room reflection and boundary conditions. The B&K house curve is an important consideration in achieving spectral decay at high freq especially in small to medium rooms. As I am building this design for my own use, I have the luxury of applying the exact curve for the speakers and for the intended room.
