Anyone able to translate and give a summary of the comparison?

I see the thread contains the words "Seaton Submersive". So are there comparisons with that too?

According to my Denon's Audassey, no. But according to Anfieldude's SPL meter, yes.

Glad to see u enjoying the new toy. So you mean you left the Audyssey setting as is after the calibration (which should theoretically be at 75 dB), but anfield's SPL meter showed it to be 79-80 dB?

Finally hooked up a PC13-Ultra to partner the resident PB13-Ultra yesterday. Result is not as what I hope for. There is a certain cancellation happening as well as sounds muddy rclxub.gif .

Did the calibration via AS-EQ1 this morning. 1 input and 2 sub outputs. As usual, EQ1 will get the desired dB from one of the front channels. Then, set the sub A's gain level to match it and continue by Sub B. After that, it's measuring process. The initial subwoofers matching is important.

Sweep tone to the front first, followed by Sub A and then Sub B. After that both sub together. Then, continued to do the rest of position. This time the sweep tone for the sub only 1 time (since it is being 'integrated' at position 1) for the rest of the positions. AS-EQ1 can do up to 32 positions.

Once it was done, I have to do channel level check again to get 75dB across all channels. it's time for some movies' test scenes. Tested Ip Man 2, TS, DTG and DF & Friends. In ULF heavy scene such as DTG's restaurant fight, TS' 7 Eleven, Kung Fu Panda, TDK as well as DH4.0 .

shocking.gif In TS' 7 Eleven, the robot stomping the ground has so much weight and floor rumbling. The door was being pushed open. It happens again for Ip Man2, DTG and Kung Fu Panda.

My customers were  shocking.gif with its sheer power. The atmosphere..... ambiance would be the ideal word, certainly up a notch. The bass is so crazy tight and powerful even at -12dB to -15dB. At my LP, I can feel that my shirt moved thumbup.gif

Glad to see things working much better after the AS-EQ1. Yeah, having it would make integrating 2 subs much easier. If not integrated well, having 2 subs can adversely affect bass quality.

Now I'm getting tempted by the AS-EQ1 again smile.gif Maybe gotta borrow it again to see how it can integrate my 2 subs.

Actually the rest were somewhere 78dB and the sub was almost hitting 82dB. The surrounds were only at 76dB. Surround resolution is better with MultiEQ XT compared to MultiEQ.
*
Quite a bit of variance there between the LCR, sub and surrounds. I remember using your CM140 to check my levels after running Audyssey. LCR and surrounds were within +/- 1 dB of 75 dB, while my sub reading was fluctuation between 76-78 dB.

Paradigm DSP-3400 = RM3800(Miri price) - 300Watts - 12"

I think the DSP-3400 is actually 14".

Also, what is good about it is the option for the PBK. Any idea how much the PBK costs here?

First time I hear my sub bottom out. I think need EQ to tune down some freq a bit. I can't use audysey MultiEQ XT as it some how constraint the sound of my speaker. The bass boost for MultiEQ XT also is crazy high matching 10hz at 105db (I think my sub start to bottom when hitting 10hz - 15hz at  110db.

Will borrow EQ1 from Anfieldude to see if it help to tame the sub. eD A7s-650 is a beast but need some control from EQ. Will post my REW graph later.

What movie and what level were you playing at when your ED bottomed out?

You mean the MultEQ XT constrains the sound of your ED or your JTR?

Earn half from everybody else but pay double price. So in actual fact we are 1/4 spending power compare to other advance country. Also, we always get second grade items. Ask Panasonic on their V model compare to US/UK. What to do, our minister all 3rd grade.

Sad isn't it? Our purchasing power for many imported goods (not only AV equipment) is so low. Cars also the same...

Usually Submersive is more expensive than a PB13U but because of this GB, it is slightly cheaper.

ronnt88 - how's your submersive? Like I said, don't worry - I did not take away your exclusivity of having one in Msia.
*
Yeah, with the GB you guys were able to nego for a very good price overall. Congrats! Now for the anxious wait smile.gif

wait til you hear about multi-million hi-fi systems in Penang. There is a group of ultra high-end hi-fi system there.

Ipoh also plenty of them. Then there are a few in Sarawak esp Kuching. Need not to mention KL / PJ.

As for HT over here, the biggest HT room measures about 40' x 60'. The coolest HT system would be a prominent contractor's mansion near the Yang DiPertuan Negeri Sembilan's Palace. It's a complete B&W 8 series system. The size sld be abt 22' x 55'  sweat.gif

Wow, those are some huge rooms! Especially the 40' x 60' one, must be a huge mansion to fit that room in.

Not sure how it can be connected to AVR. I see a pre-amp input port, but the connector is unusual.

Wow, sounds like the DSP3400 is the sub to beat in the 3K+ range.

Yup, Mark definitely has to improve his response time. Imagine all the extra business he could get... or maybe his demand in USA is so good that he has less time for overseas queries? smile.gif Except maybe for large bulk orders...

the DSP3400 retails for USD899 in the US, similar price bracket as the PC12+ which are going for USD949. the PB12-NSD retails for USD599.

Seems that Paradigm is good value in MY like what htkaki mentioned. For DSP3400 US$899 RRP over there vs RM3.3k here (3.67x). Or the Sub 25, US$4000 RRP there vs RM14.5k here (3.63x).

Paradigm must have a very efficient int'l distribution system.
