About two years ago, I decided it was time to upgrade my entire home theater.  At the time I had a Denon 3801, SVS SBS-01 speakers, SVS PB10 sub and a Hitachi 56” CRT RPTV.  Prior to that I had a Klipsch RC-1, Klipsch KSW12 and a pair of old Altec Lansing and Yamaha speakers.  When I first started researching, I was looking into Rythmik, HSU and Epik for a sub and Ascend, Salk and a few others for speakers.  I got a Denon 3311 and Mits 65” DLP TV but could not make up my mind about the sub and speakers.  As I continued researching, I kept coming across posts about the Submersive and how people with a lot more experience in this hobby than me were extremely happy with it.  I decided to throw out my original budget and I bought a cherry red submersive.  I was lucky in that I ordered it right before Mark announced the HP upgrade, and got the HP for the price of the original.   Needless to say it was a huge upgrade from the SVS.  It went much deeper and louder with less distortion. 

Even though I was extremely happy with the submersive, I was still struggling with what speakers to get.  I was very interested in the CAT 12Cs, but they were way over my revised budget and although I read a lot of good things about the sparks, I was hesitant to go with another 2 way design for my mains.  Again it was good timing, because soon after I bought the submersive, Mark posted about the 8C.  After a brief discussion with Mark over the phone, I placed an order for 3 cherry red CAT8Cs. 

I’ve had the 8Cs for a little over a month now.  I’ve been very busy at work so have not had a lot time for setup or listening.  I did have time for a quick measurement session and was able to get a few hours of listening today.  Today was the first time I really turned up some music.  I listened to some Tool, Morphine, Eric Clapton Unplugged and Nirvana Unplugged.  I don’t have a lot of experience with “high end” equipment for comparison, but one of the biggest differences from the SVS speakers so far is the clarity as the volume goes up.  The SVS speakers would become a little fatiguing and would distort or compress at higher volumes.  The CATs didn't change at all as I turned it up.  They were clear, detailed and not fatiguing.  I don’t know if its just a lower crossover or the CATs themselves, but they also seem to integrate better with the submersive.  This was very apparent with the Clapton CD.  There are some subtle bass lines in a couple songs that sounded great.  The bass was present and added a lot to the music, but the submersive never called attention to itself.

I’ve only been able to watch one complete movie, Star Trek, but it wasn’t at a high volume because one of my roommates was home.  I just got a couple blu ray concerts (Dave Matthews and Tim Reynolds, Eric Clapton Crossroads and the Rock and Roll Hall of Fame 25th Anniversary) and a few movies (Tron, Inception and Open Range) that I am planning on watching soon.  I’m already enjoying the speakers and am looking forward to fixing some of the problems and getting everything dialed in even more.  Hopefully the CATs will be on matching stands soon.

Here is some information about my room.  The entire floor is open with 11’ ceilings.  It is about 10,000 cubic feet.  Here is the floor plan and some pics.

Here are some measurements.  Measurements were taken with a Dayton EMM-6 mic calibrated by CS Labs and a Tascam US-122.

This is the SVS PB10 through the 3801 and the Submersive through the 3311 with Audyssey turned on.  Both are with the SVS SBS01 speakers.

These were taken with the CAT8Cs,  Audyssey enabled and a 60hz crossover.  Previously I had run Audyssey with the Submersive in DSP 1. This time I ran it in DSP 2.

The first thing I want to change is the center channel placement.  My first plan is to use a taller table for a TV stand that will allow me to raise the center up and push it under the TV.  I just need to figure out how high I can raise the TV without causing problems.  Then I will buy or make a custom stand for the center.

 I am also debating what to do with the surrounds.  Should I upgrade them and should I mount them high on the wall? 

From the measurements I have two dips I want to address.  I am going to try changing the sub distance to see if that helps, but I don’t know if it will.  If you look at the measurement of the left only, there is no dip at 60hz, but there is a small dip around 140hz.  From the right only measurement, there is a large dip at 60hz and a wider dip at 140hz.  I don’t know what to try to fix these.  I would love to get a second submersive, but I am in a townhouse and I don’t think my neighbors would appreciate it.  I need to do some full range measurements to see if there is anything above 200hz that needs addressing. 

I am debating wheter to use a pair of my old SVS speakers as DSX wides.  After I get new furniture, I think I will have the room.

Eventually I will be looking into if it is worth it to get some treatments.  

Any comments, criticisms or suggestions are welcome.  If you want any other pics or measurements, let me know.

Thank you for posting this Mike. 

The one measurement I see missing is the SubMersive alone.  Test this through the center channel while switching off the center '8C and add it to the graph above of the center+sub.

Keep enjoying and experimenting!

I already had these measurements, I just forgot to post them.  Graphs added above.
