Which REL sub, R528 or B2


I'm planning to buy a REL subwoofer. It will be used in audio system mainly, but also in HT from time to time. I listen to jazz, vocals, occasionally rock. It will support Dynaudio C1. I'm considering the new R528 or B2 ( can get them at roughly the same price).
The new 528 looks better but is it as good as B2?

First of all I use Audyssey Pro. Second I meassure at different hights and places what Audussey discribes. What is the different between the Audyssey way and my way. This is very big. I did test many different ways of measering in over 2 years time. My way captures a lot more dynamic and details. Focus is sharper and I play about 1 metre beside my spakers and about 4-5 metres behind the speakers. As you know sound becomes touchable above 80hz. My sub starts at 16 hz till 140 hz at this moment. Wenn I go higher the overwhole sound becomes even more touchable. The PLW15 of Monitor Audio is a 50kg sub which box is sealed. It has a 15 inch unit. The respons of this unit is superior in speed compared to brands like Rel and Velodyne. Material they use is a lot lighter. But very stiff. The magnet they use is very big and wide. My subwoofer stands more on the right side of my front speakers. Instruments are still very small in dimension and very direct to locate. I test many sub's in respons and if instruments and voices are still in proportion. A friend of mine had a small concerroom with a Steinwaywing. He gave classical concerts of about 2-3 people. Instruments and voices are very smalle in proportion and very easy to locate. I was amazed how much smaller instruments and also voices are in proportion. A voice and even an instrument sounded so much more intimate. That is why I hate systems wenn instruments and voices are too big in proportion. You will loos the intimate sound. Intimate sound is one of the most important parts in realistic sound. It sucks you into the music. Wenn instruments are being played to big the distance between you and the music gets bigger. This means less emotion. Of all the cables I tested Audioquest and Purist Audio design are both capable of giving an intimate sound. I call this individuel focus of instruments and voices with the right proportion. I had this discussion with musicans. They will tell you the same about how big instruments and voices should be. With Audyssey Pro and the PLW-15 the first time in my life I heard stealth low freq. 4 weeks ago I had my set at a show of over 50 distributers. They said; I was the absolute sound of the show. Why? Because I had a 3d stage whit a focus most people never heard this sharp and touchable. It was easy to let people know what depth is and a 3-dimensional sound. The last day was a day for shopowners. Many never heard a sound this good. For many it was new that there music could be so sharo focussed and touchable. Cause of the wide and deep stage you hear every single instrument and voices by ease. I did do hundreds of tests during 15 years. This gave me a lot of information what I use. That is why I know all the different properties of many brands. This makes it easy to compare. Time and technique will make you think differently about audio. I never wanted a subwoofer to use of stereo. These days timing and speed did change my mind about this. I always used big loudspeakers like the B&W 800 Signature without a sub. Now I would not want to miss it anymore!!
I have the R528 attached to the astonishing Focal Micro Utopia Be - The result is magnificent.
The sub blends perfectly: Fast, Realistic bass.

I use Audioquest Sub-3 + Russ Andrews-Kimber Kable 8TC Neutrik Speak-on REL cable.

The room is about 35 square-meters.
I'm using a Rel B3 connected to a Synergstic Research Rel Spec
Reference Subwoofer cable and using a Synergistic Research T3 SE
Power Cord. This sub effortlessly integrated with my system with speed
and power. Best sub I ever owned.
Joey - Did you have the original Rel cable when you first got the B3? If so how would you describe the difference after upgrading to the SR cable?
Yes, I used the original but after I installed the Synergistic Research
cables and I noticed a lot of definition and separation of instruments.
Especially in the bass department. This sub is fast enough to keep up with
my Focal speakers and disappears and is unlocated. The bass is perfect
low and loud in my room. Only one was needed in my corner to supply all
the bass my room needs. I also tried Audioquest and some others but they
were not the best. Synergistic Reseaech Rel Spec Reference Cable does
it all.
