What about "You Only Live Twice"?

Sunfire Theater Grand III Sunfire Cinema 7 Onix 2150 2-ch (R/L side-axis)

Interesting thread, especially the part about the eq boost with an SS filter. I am also running an asymmetric configuration--B4+ (one port blocked) with an SVS black box (SS filter set to 12hz). Does anyone know if the black box contains the same type of eq boost as the SS filter in the PC+'s...

Great! Thanks for the link!

Based on the user response in the forum, I purchased a BFD several months ago and experimented with equalizing twin SVS 20-39PC+'s (e.g., lots of trial and error). I have since upgraded the PC+'s to one B4+ and am ready to start the process all over again. Final position of the sub in the room...

Empire Strikes Back--pilot's briefing at the beginning of the Hoth battle: "Two fighters against a Star Destroyer?" The delivery of that line is just horrible. Also, the "spontaneous" cheer when the first transport gets away.

Not dialogue per se, but the breathing noises Lambert makes over the ships intercom at the end of Alien--it almost sounds like Lamaze breathing and it creeps the hell out of me as I imagine what you need to do to a person to make a sound like that...

We'll find out soon enough--I've got a baby girl due in two months and a dual PB2+ set shipping next week (fingers crossed). We watch a movie about every Fri. night in the home theater. Maybe I should lay down a little plastic, just in case... :)

Hey Richard, Make sure that you've got your volume *much* lower than your average listening volume in DD/DTS. For instance, I watch movies at -25, but work with the BFD at -45--those sine tones can be murder on your sub's voice coil! Try to let them play just long enough to get the SPL...

If you mean that at "reference level" (for me, -10 on my pre-pro = 85b on the five channel speaker level test), the subwoofer level signal (as it bounces between the front left speaker and the subwoofer) is at 81-82db, I have noticed that too. It's unclear in the menus whether you need to...

OK, I've got some new data from last night. First, I left all ports open on each sub, set the SS filter to 16hz and played the opening of AOTC (Cavalcade and Ship Explosion) at -20 (with the subs about 5dbs hot) [-11 is 85db reference in Avia, highest listening volume is -25]. No ill effects...

Did you run with all ports open, but with the SS filter set to something other than 20hz? If so, any problems with bottoming in this config?

Thanks for all the responses! Later this evening, I will try some slightly altered placements for the sub and a run with one PC+ at 16hz and one at 20hz (should be interesting). In addition, the HT is located in a room above a detached garage with lots of floor movement/rumbling in the...

Taking my cue from the legions of other HTF members desiring that perfect subwoofer response curve, I endeavoured to first assess the damage being caused by my room and also determine what effect tuning my SVS 20-39PC+ to 16hz would have. Both subs are located in the same corner of a 21x29 room...

I will give the internal tones in the pre-pro another shot. Just for the record, however, the problem I was having was the opposite of that which you are describing in that calibrating with the discrete pre-pro tones resulted in *too low* of an Avia reading v. *too high*. Hopefully, the new...

Thanks, Ed. Interestingly, difference in calibrated levels of the speaker channels (L/C/R/RS/LS) between Avia and my pre-pro's internal test tones is negligible. When I calibrate the sub to the discrete, internal test tone of my pre-pro however, the Avia reading is far below that of applicable...

Normally, I select Avia's left front/subwoofer level to calibrate my subs, then run the left front/LFE frequency sweep to gauge the effectiveness of positions/settings. Last night (while experimenting with new subwoofer locations), I noticed that the sub level in the left front/subwoofer test...

I will put a call into Sunfire to confirm what the proper subwoofer tone should be. Currently, the internal subwoofer tone is 10db less than the Avia subwoofer level. Seth_L, you guys had to up the sub output by 10db's in Dallas for DTS/DD, right?

According to the manual, all 3 sub outs output the same signal.

OK, after exploring the unit last night, it turns out that hitting the "Mode" button (either on the remote or on the front panel) toggles between a 5.1 input/5.1 output and a 5.1 input/7.1 output mode in both DD and DTS. I believe (but cannot tell for sure) that the "forced" 7.1 is just matrix...

Seth_L, LOL--this is the Sunfire unit from the AV123 show! Brian

I understand that the Sunfire TGIII is not an THX Ultra2 pre-pro, but does it provide capability for creating a 7.1 mix off of a 5.1 DVD (similar to the THX Ultra2 Cinema mode or the Cirrus Extra Surroud on other pre-preos)? Thanks in advance, Brian

Aaron, I have a similar problem, but with a completely different set of components and speakers--dialogue on certain DVD's (usually when a character is raising their voice or yelling) creates a "fizzing"-kind of distortion behind their speech. This distortion only occurs in the center channel...

I have a 5ES and a 20-39 PC+ and love the combo. The only observation I would make is that I had problems with the PC+'s auto on function with the subwoofer calibrated as in the SVS manual (e.g., start with the subwoofer gain knob at 50% and the receiver's subwoofer level setting at 1/3 up and...

Yogi, The B&K manual refers to the 12V trigger on/off function as "muting". Jason is correct above when he states that when the receiver or pre/pro signals the amp to "mute" (e.g., red light goes off), that the amp is room temperature to the touch. I'm not sure of the difference either between...

I have a Reference 7520, Series II hooked up to an unswitched outlet on my HT power center. The amp is connected to my receiver/pre-pro by a 12V trigger. Can anyone tell me if the amp is still drawing power in its "muted" state? According to the manual, the draw at idle is 100+W, but it's not...

Thanks for the response, John. Regarding the "in-line filters", I had found a reference to the products at Link Removed (with the text reproduced in relevant part below): [Line Level Low Cut Filter - get rid of the rumbles! Available in a variety of roll-off frequencies (Fc) - get the right...

I would like to augment my HT with an one of the SVS PC-Plus' (probably the 25-39). I currently have a Polk PSW650 subwoofer (dual 10" drivers; good to about 30 hz, but lacks low-end) and since budget constraints would prevent me from buying 2 SVS', I was wondering if the SVS and the Polk would...

After reading horror stories about "bowing" resulting from placing heavy center channel speakers on top of Mits projection TV's, I mounted my Polk Csi40 above the TV on a Vantage Point PTW20-B angled TV wall mount purchased from Best Buy. Although I am with happy with the placement and the...
