As mentioned in my previous post .....
"One of my customers who lives about 100 miles away (and has become an audio buddy) has told me that he really didn't care for the F-15 drivers at first. His original speakers had Betsy drivers and he added a second pair of baffles with the F-15 drivers.
He stated that it took about 500 hours of playing time in his system before the F-15 baffles sounded good to him ..... and now he loves them.
He will be visiting tomorrow to do an A/B between the F-15 and Fast-15 baffles in my room."
Here are the results of the visit .....
We spent several hours doing an A/B of the F-15 and Fast-15 drivers in identical baffles.
I asked him to share his thoughts during the session without providing any of my opinions or observations in advance.
The results were that his observations were nearly identical to mine.
The following is just my opinion (in my listening room with my equipment and playing music that I enjoy and consider "well recorded") and should be taken as such .....
The Fast-15 drivers certainly are "lively" sounding.
I still have some music in my library that is "hot" or "thin" and if a person's music falls into this category, these are probably not the drivers for you.
On the vast majority of the music in my library, these drivers are a revelation.
They combine the lower midrange / upper bass response of the original F-15 drivers with the speed and upper frequency response of the Lii Audio Silver-10 drivers.
They create a HUGE soundstage / stereo image when the recording contains such information.
The separation and space between instruments and vocalists is excellent.
My system includes a third baffle with a Lii Audio W-15 bass driver which adds a nice "foundation" to the music and has to be factored into my final take on these drivers.
The addition of a ZROCK2 in the mix works very well ..... at least for me.
So, there you have it.
I also expect them to improve with additional break in.
Based on my experience, every Lii Audio driver has a "raw" sound until well broken in.
Conclusion - if a person has reservations about the suitability of these drivers for their system, go for the original F-15 drivers.
If the solution to "tame" these drivers that Steve is working on pans out to his satisfaction, that will be an answer for many buyers.
Happy listening,
