Just an FYI for all interested party's, oh, and Sid, he stacked the LSi's on the RT800i's...
And Doc, well done....!

I sure don't know where he finds the time. Reading that I think I have to start saving my money if there is a big diff, between the 2+ and the ultra that can justify the cost. Cant wait for his review on the B4 when he gets one of those
hell maybe the B4 will get the ultra drivers to give it that much more, now that would make even the most bass hardened listener feel satisfied. Reading things like that just gets my gears moving.
Dave -
Damn. Doc even brought the sub outside on a pallet to do ground plane testing. That is one heck of a long interconnect / power wire. I thought to myself "he can't be serious" when he told me once to try that out. I guess he was serious afterall.
Kudos Doc. You have outdone your last review again.... as hard as that is to imagine. -
Thanks, guys. That was a fun project. Yeah, it took forever, but you pick away at it and it's not too bad.
Ground plane is better for really powerful subwoofers like the PB2-Ultra. Inside, they rattle the entire house and create false positives on the distortion spectra display.
And it's hard to get a decent nearfield FR curve because the box is so big and the drivers and vents are too far apart to get decent summing at 1 meter.
2 meters GP is the gold standard. I just wish I had better weather so I could GP all year round."What we do in life echoes in eternity"

Now, how did the 7's blend for two channel?

Excellent review, as usual. I wouldn't expect anything less from Dr. SVS...I mean Spec

Ha! No where else to put them for the present. They are a bit high for optimum, but still sound really good.Now, how did the 7's blend for two channel? Was that in your review and I spaced it?
The 7's have remarkably good bass response into the 60's, which is perfect for an 80 Hz xo to a sub.
I didn't discuss the 7's per se in the review. I did discuss how difficult it can be to get a smooth transition from the speakers to the sub.
You can see how ragged the transition bandwidth was before I optimized the phase, low pass, and PEQ on the SVS. Worked out really well actually.
The only thing I did differently so far with the 7's is disable the low pass on the SVS. I haven't spent a ton of time looking at the crossover between the 7's and the SVS yet."What we do in life echoes in eternity"

My 7's are atop my 800's as well... I didn't think the 7's would have much of an issue blending, but just wanted to be sure...There is no genuine justice in any scheme of feeding and coddling the loafer whose only ponderable energies are devoted wholly to reproduction.

Not only do they blend well with the SVS, they also blend well (surprisingly) with the CS400i across the front stage.
I thought the timbre match would have been poor, but it's not."What we do in life echoes in eternity"

when i tried my 7's on top of the 70's unhooked of course, i calibrated them and it seemed by time the 7's were loud enough the svs was way to loud, maybe i did something wrong...MY HT RIG:

i calibated them
I found the LSi7's to be about 2.5 dB lower in sensitivity than the 800's.
I saved my old settings for the 800, so I can switch back and forth as needed. Right now, I'm leaving the 7's running for both music and HT applications."What we do in life echoes in eternity"

Other way Faster... Turn the sub down 2.5 clicks...There is no genuine justice in any scheme of feeding and coddling the loafer whose only ponderable energies are devoted wholly to reproduction.

I recommend recalibrating the entire system when new speaks are added.
Dropping the sub level will work for 2 channel, but not for HT, where the other speakers would then be louder than the less efficient 7's.
It's a good thing to check system calibratrion occasionally, anyway."What we do in life echoes in eternity"

Thanks for the correction, so what about for HT? are you useing the 7's in HT for now? and if so how do you get them to sound equal to the other speakers... and subMY HT RIG:

You can calibrate each speaker seperately and once set, they should stay set. Some pre's/reciever's will have different settings for multichannel and stereo modes, some don't. But once you have all the speakers calibrated, you should be set for all volumes and formats. This worked when I was using mismatched speakers and also works for the matched pair. You pretty much have to start all your calibrations over again.There is no genuine justice in any scheme of feeding and coddling the loafer whose only ponderable energies are devoted wholly to reproduction.

Dam - got me looking at the PB2+ again. May be putting the PSW1200 on Ebay this week.

Take a close look at the power compression curves for the PB2-Ultra in the 25 Hz tune. 115-120 dB at 2 meters OUTSIDE?!!
In a typical room, the PB2-Ultra in the 25 Hz tune will not begin to compress until close to 125-130 dB peaks in the 25-30 Hz region. I've hit over 120 dB - at the seat - on Underworld."What we do in life echoes in eternity"

What would the differance be using the 2+? The 2+ shakes my house now as I'm sure it did yours does the Ultra shake it much noticably more at the same volume and settings?

The PB2+ is right behind the Ultra - subtract about 2 dB across the board. The PB2+ is a better performance value, no doubt."What we do in life echoes in eternity"

I think the difference at that level is quality of parts moreso then better performance per se'
you get a better cabinet, better drivers, bit bigger amp...
but the same overall setup,
I say the pb2-isd and + are a great value/performance buy
when you get into it like Ed, its the natural step up to get the Ultra and go all out... he will most likely never 'Need" another sub, But want is a different story... like when i went from pb1 to pb2, I really just wanted the pb2 Bad

That Maple finish is awesome. I will enjoy the black - my home style is much more comtemperory.
Doc - what did you do with the other SVS? It was a PB2+ right? -

Sold it locally, actually. It's pounding away in a Klipsch Reference 7 system and sounds fabulous."What we do in life echoes in eternity"

Yep, it is working great now. Back then it was a under achieving 150L with an 8" port. With your help I decided to build the EBS. Since then I rebuilt it for fun with more attention to details and some slight modifications. I think I will post a FR curve if anyone else is interested in what you can do with a DIY sub.Graham

Doc:
Hell of a review! I enjoyed it tremendously! The guys at SVS should put you on the payroll!
It's great to hear how well the 7's blend with the SVS and the CS400. I picked up a pair of 7's recently (the Fry's deal) and plan on using them as the main L&R in my surround setup. This will eventually promote my SRS 2.3's to a 2 channel stereo setup.
Again, great review!
JohnNo excuses!
