Ordered a new B4+ (1 Viewer)

[Allen Marshall]

Gonna kill two birds with one stone here and ask the same question in this thread and my B4 thread.


Does anybody have any reviews on the B4+ other then Secrets of Hifi. Further more how bout SVS comparisons, all i've read are reviews on most of the SVS subs by themselves but no comparisons with each other or other subs except for Tom's tests on the site. Did read Ed's two reviews though.

Only interested in PB2-Ultra and down if there comparison reviews, read a million reviews on just the subs, think i got the jist of it. But B4 reviews, i'll take those anyway i can find them cause google aint bringin up anything.

Allen - I was going to not do a full review on the B4+ ... but if there is interest, I can easily enough.

Craig:

I would like to hear your opinions on the B4+. It would nice to hear your opinions on the differences you have found between your Pb2+ and the B4+.

Parker - Ok... It will give me something to do after I butcher a golf course.

Craig-

While it is quite clear that the B4+ is highly capable in terms of pure output, the investigation I have not seen done yet would be with the changes observed with the different tunings. No need to duplicate what Johnson did in the Secret's review. A series of tests from say 14-30Hz in each mode would likely prove very informative. Combine that knowledge with an outboard EQ and you will offer a perspective that hasn't been covered in what I've sen posted. The lack of EQ and careful calibration beyond a simple number on the SPL meter is a factor which accounts for a great deal of the variation in experiences with a given subwoofer. Significant peaks in a subwoofer's response will wildly throw off a system when setting levels with the standard test signals and SPL meter.

 

[Craig Chase]

Mark - That was about as nicely as anyone could have said that the Secret's review was not very thorough...

And I totally agree... what can it do with different tuning... plus I have a few EQ devices- the Audio Control Richter Scale with 1/6 octave eq, the impending R-Des from AV123... and the SOS unit from Speaker City... I will start with an un equalized sweep, and work from there

Hi Craig,

Sent you a PM.

Man, it was a bad time to be in my area yesterday, anybody watch the news? lol

Anywho yea your PB2-Plus compared to the B4+ would be a fun review to read.

 

[Craig Chase]

Allen .. Saw that about the tornado... scary stuff !

One area of interest... will the Crown K1 "sound" better with the dB12 drivers than the built in BASH amp on the PB2+ ?

Here is a picture of a partially finished B4+....

And Here is where the B4+ will take up residence....

 

[javry]

wow! Now, that's a theater. Where do you keep you equipment?

[Craig Chase]

I will post more pictures later, all the electronics are in the back wall, and yes, my bride enjoyed decorating this room !

 

[Craig Chase]

This made it easy... The K2 was about $200 more than the K1... The B4+ should ship sometime in the next few days...

Just about in time for Ed to start the PB2 Ultra review...

And for those who know what this means, the K2 has a rated damping Factor of 3000 + from 10 HZ on up... That should keep a handle on things...

Craig, aren't the Belles kinda hampered there behind those two chairs?

 

[Craig Chase]

Jeff - There is actually about 5 feet between the chairs and the Belles... and they really are not noticable...especially with the center channel ... From my listening position, there is a clear view right to the speakers...

That being said, there IS a reason I have a two channel only system for music in another room

Craig, the standard for sub output at Dolby reference volume is 115dB (peak) at the listening position, IIRC.
Of course, there are some movies that even go over that and you can quite easily hit 120dB or more
on the sub bass if listening at ref. for certain movies. Star Wars: Attack of the Clones goes over
ref level, for example.

 

[Craig Chase]

Lee - I am aware of that. You did not complete your point... Why did you write that ? To make sure I knew it ? If so, thanks, if not... out with the details ...

 

[Lee-c]

Craig: You had posted before a question about volume levels at reference. I just wanted to state what the
spec officially calls for, which is 105dB peak for standard movie sounds, and 115dB peak for subwoofer LFE sound.
Although, one can't always count on a movie restraining itself to those levels. Of course, with a B4+
you won't have to worry about that.

Off the top of my head, I think the B4+ can do something in the area of 130dB, if the room isn't too big,
which is probably more than you'd want to listen to anyhow.

I look forward to seeing some measurements as well as general opinions on the B4+ once you have it.
