IME, and this is not SOP, but I've found that you can "move" the sweet spot a bit if you mess with the phase on your rear sub(s). Your subs will be slightly out-of-phase, but it sometimes works. Give it a shot!

OK, just got off the phone with R+L Carriers.

The reason my tracking ended in Minneapolis is because the T-18s got handed off to a "secondary carrier" who apparently is "unmanifested"....anyways, the T-18s arrived in my city this morning!!

They said they should be calling me in a couple hours to schedule delivery. YEAH!

Just received in my dual XS30SE's yesterday and just wow....They were fantastic sounding!! Once I got them dialed in with my system I was very impressed with how tight, controlled, and deep the bass was. I had never heard or owned sealed subs before, only ported. In my current theater room of 3000 Sq ft these shook the walls! Very impressed and very happy! Tom answered at least twenty of my questions prior to purchase and also afterwards. Very impressed with customer service and the overall experience. Looking forward to years of use out of these!!!

Awesome, I just set up a return for my XV15SE so I can save a little and get an XS30SE for my 2,000 cubic foot room.

All orders up to today should be fulfilled. Please check your inbox for tracking. Orders starting today(12-16) through the rest of this week won't ship for 2-4 business days as we are waiting on more inbound 4000 watt amps.

There is a sliding patio door on the left side, but I have fake leather curtians over the glass.
Banboo flooring on post and beam with large rug in the family room.
MLP is average 10-11 feet from subs and towers.
Sub 1 is left side of front wall - 3 feet from left corner wall and 10 inches from front wall.
Sub 2 is on the right wall - 3 feet from right front corner wall, and 6 inches from right wall.

I have also notice the subs drop off rapid after about 19 Hz and by 16 Hz has fizzled out. So I take it that there is no room gain?

Dual XS15se subs.
Hello Red,

How much placement flexibility is there in the room? I ask because I would be curious as to how NF(near field) placement sounded in this environment. I'd say 16-18hz would be about right. There should be a sudden drop off though unless it is related to a room mode in some way.

The XS30se are a bit better than the XV15se even in a large room environment like this. The 30s are going to extend a bit deeper, they will have similar output capabilities in the deep bass, and the 30s will have close to double the output in the mid and upper bass(45-100hz). So I don't think moving to dual XV15se would feel like an upgrade. Let's be sure we have the 30s optimized before jumping ahead of ourselves though.

Tom, I don't have the 30s! I have two XS15se's. I did some more measurements tonight. A little different than before. This time I used the sensitivity factor pasted in my calibration file instead of calibrating the mic with the SPL. And I found a 5 dB difference at 70 dB.

I have a little flexibility with placement. When I did the crawl, only one spot had more loudness, but I couldnt tell if the sound was better, and that was on the left side of the sofa next to the left surround speaker.

I did one compression run and another with each sub and then both together. Let me know what you see out of this. It seems to fall on its face right after about 19 Hz but then picks back up before running off the graph.
The 2nd graph lower measurements are each sub. The top two measurements are both subs on together

just so you know, the customer service you get from them does NOT stop when you purchase one. they are just as helpful a year after the sale as they are just before it. you won't find better than jim and tom...they are top notch in every facet.

Anyone has a good advice on how to blend XS15 (non-SE) for stereo 2.1 music into my humble setup of Harmon Kardon HK 3490 stereo receiver with line-level Sub Out but no bass management. I have to use crossover on the XS15. Speakers are NHT SuperOne bookshelves with lows being around 80Hz. I cannot find a good test tracks to use for that or any settings that will work. So far after a LOT of trial and error, the XS15 underwhelm big time right now but I know it is due to settings. I did all the drills from the manual but I think I missing a big trick somewhere because my setup is stereo receiver not typical HT.

Thanks.
