SVS on TechTV

Jeremy Anderson · 01-04-2004, 09:49 AM

Secrets' John E. Johnson did a segment on TechTV's Call For Help this week where he set up a home theater on their set. I was glad to see that the sub he used on the show was the SVS 25-31PCi! I thought it was very cool that John hyped SVS on national television. Leo Laporte and crew seemed to be very impressed, as it shook their control room 30 feet away. I guess now they know what the rest of us SVS owners have known for a while -- SVS is da' shiznit!

Jeremy,

Believe it or not we had notice of the airing, but coming as it did the day after Christmas and us still working thru a crush of e-mail and orders we didn't have time to record it!

According to Dr. John Johnson, there were actually two segments because the first one ran over. After CES we'll probably have something in place so that we link to Secrets and the video.

I did hear the crew at TechTV was fairly astounded with the PCi's performance. Anyone that owns one certainly isn't too suprised ;^)

My backyard neighbor, approx. 50 ft. away (42' to the 8' high redwood fence, with a 30yr. old pear, apricot, peach tree in between, ... approx. another 8' to his duplex back wall) was impressed on one agressive Friday NITE DVD presentation of "Atlantis: The Lost Empire" DTS ES-matrix @ -5 dB below REF Level** (approx. Fast LFE SPL peaks = 110 dB / SVS 25-31PCi

)

He came over, walked around the block, ... during the finale, ... I finally heard the doorbell during a calm dialog scene!!! :b

Interestingly, backing it down to -10 dB*** (approx. Fast LFE SPL peaks = 105/106 dB) doesn't rattle "his walls & windows!!!"

**NOTES:
.... All double pane windows, skylight, double pane 8' glass sliding door was closed and the walls & vaulted ceiling is insulated (R19)!!!

***
.... -10 dB below REF Level has been my normal once or twice a month Friday NITE DVD presentaion for my family / friends since 1998. It's still loud enough to move the air, floor, couch, wall, (SVS trait) pant leg's @ my seating locations when the LFE calls for it, but still maintain an audible dialog level during the whispering moments during the quieter scenes of the DVD movie!

Great Ron, ... looking forward for the video link!! !

Everyone always talks about how their SVS shakes the room and such. I just got a 20-39 PCi, and after careful calibration with Avia and an SPL meter, the bass is terrific, but there's not much shaking going on.

Could it be because my room is in the basement, and underneath the carpet is a concrete floor?

WayneO · 01-05-2004, 04:34 PM

With a concrete floor, yeah, it's kinda hard to rattle that.....

My PB2+ is in my living room(plywood sheets on beams) above my basement and it does shake everything.

Ron Stimpson · 01-05-2004, 08:06 PM

John,

That's exactly the case as Wayne said. There is little flexing a cement floor, and you do lose the tactile waves a typical wood joist floor will have by its nature.

Put the sub in an upstairs room, calibrate it the same, and you'll be shocked at how different the feel of the sub is.

In my last HT, the first row of seats was on cement/carpet, and the second was on a riser of about 8".

We're talking 3' separated the two rows of seats and the subonics were entirely different experiences.

In some cases you can just use 2" firring strips to make a kind of subfloor (no pun intended) with plywood or particle board as the sheeting and then your carpet.

It probably would work well for you, as might some experimentation with your current placement of the sub (you might have response nulls working against you that only a different location for the sub will correct).

For quality bass, I'll take a concrete floor over a wooden floor any day. A wooden floor (particularly over an open room below) has boom and uncontrolled resonance that a concrete floor just doesn't. Hell, jump up and down upstairs and you'll see what I mean. Try it in the basement and all you'll get is sore feet.

My old 20-39PC+ now resides at a friend's house and it literally turned his cheapo wood floor (over a basement) into a virtual trampoline (with all kinds of unnatural boom). Two huge concrete pavers (100 pounds total) under the sub decoupled it and presto - much less boom. Just goes to show you the room/floor can ruin the sound of even the best sub.

IMO the sub should pressurize the air, not resonate the floor. If you aren't getting your pants waffled on a concrete floor, just buy more sub.
