They've taken me from content to happy with my system. They are a noticable improvement over my old Klipsch KSB1.1 monitors and will serve me better than the Klipsch did until I get the chance to build a full set of Kit281/LCC, VSS Eros or something similar (1 to 3 years down the road).
They image very well, create a deeper sound stage. The mids and highs are cleaner and more detailed (I also compared the S38 to a PSB Image 2B at A&B Sound and had a definate preference for the S38). They also extend much lower allowing a better match through the 80hz crossover of my Onkyo receiver to my sub.
Just wanted to say that you have a pretty awesome and detailed web site there!
The amp mod section was great as I will have a need to do this mod myself soon. I also enjoyed your sub creation section as I am slowly working through this process myself. What made you decide to go with a 250L design. I am undecided on volume myself. I have recently learned LspCAD (a painful process) and in my modeling, the 150L appeared to be better than a 250L design (which is the max I can go). I am planning on putting it in 20" sonotube.
Stands look good, you've got a nice HT. Congrats on your new JBL's. I was using 4 G500's before converting to a Klipsch set-up. I've always liked the sound of JBL's: very clear, detailed, and full. Of course once I heard the horns I fell in love, but the JBL's sound great in the bedroom.
I wanted a small foot print and as close to an EBS alignment as possible. The smallest tube I could easily use with a Tempest was 18". Making the sub 6' tall I was able to get a net volume of 260L. This allowed me to use a 6" port to tune to under 17hz (not feasible with a 150L enclosure). And from my modelling in LspCAD produced better sub 30hz response. I also got some help from Dan modelling my room in LspCAD. The in room response graph looks a lot different than the free air does.
I'm curious what in your modelling led you to believe the 150L enclosure was better?
Thanks Mike. There is no comparison between the small Synergy bookselves and the JBL Studio Series. But the KG/LF/Reference lines from Klipsch are a different story.
