Paradigm Sub 1 and Sub 2 - Page 6

Anyone had a sub2 delivered yet? I am told mine is to ship next week...perhaps on tuesday.

I would also like to hear more from the one person on here who seems to have a sub 1. How does it sound? Was it what you had hoped for? How is it with movie soundtracks and LFE?

Thanks

lucky you

Well, Paradigm made a mistake and none of the first batch of Sub 1s (and maybe Sub 2s) shipped with the PBK-1, so I've been running using only Audyssey MultiEQ XT, which doesn't seem to do much to attenuate the room's fundamental harmonics. My PBK-1 should be here Tues or Wed, so we'll see if that improves the room response. Between lack of good EQ and no room treatments, I don't think I can make any more observations than I already have in this thread.

It can produce enough output to cause physical pain (in a huge room no less), but is fast enough to resolve every note on a bass guitar or upright. The enclosure is also very small and attractive. I don't know what else to say...

how did you choose between the sub 25 and sub 1?

I covered that in post #95ish (which you replied to ). I did not get to listen to either prior to purchase to compare. In addition to the other reasons I covered earlier, it boils down to 'cool factor'; there are dozens of sealed 15" sub designs w/ box enclosures, but the 6-driver hexagonal arrangement is unique to Paradigm (albeit similar to Martin Logan's well-respected Descent).

i agree 100% do you plan to add a sub in the future or this is it?

I'll see what the PBK can do for the room response first. If it's pretty flat, I'll stick with one sub. Otherwise, I might need a second one to level things out. I'm happy with the output level though.

Room treatments and upgrading to separates are probably higher on the priority list than a second sub right now.

So I got my PBK-1 today, and I ran it for three different locations of my Sub 1. I settled on a spot on the side wall, about 40% back from the front wall. Here is my before and after response from 20 Hz to 100 Hz:



Before EQ, I was about +/- 3 dB over this frequency range. PBK brought it within +/- 1.5 dB.

I still have pretty strong coupling with the fundamental room modes at ~20 and ~30 Hz, but there isn't much I can do about that (even bass traps aren't effective that low). Overall, I'm happy though.

sweet keep tweeking it im sure after a few ore trys it will be even better but congrats man.

do you give the pbk-1 the thumbs up?

Looks like you have a good deal of cancellation there and room interaction...

Def some improvements could help out that response. Bass traps...?

It's an easy-to-use, effective tool, and I'm glad it came with the Sub 1. I personally wouldn't spend $300 for the standalone PBK-1, only because I'd prefer a sub EQ with more user control. The PBK-1 is great for someone that just wants their sub to sound better without getting into the nitty-gritty of room modal analysis, though.

is the PBK only for Paradigm subs?

Yes, and only the newer, higher-end Paradigm subs at that.

EDIT: The Paradigm website currently lists the following subs are being compatible with the PBK-1:
SUB 12
SUB 15
Seismic™ 110
SUB 25
SUB 1
SUB 2
X-850 (the amp for their in-walls)

Not True. Paradigm's pbk is compatiable with most all there newer subs. From the DSP to the top of the line subs. I think I read it was going to be compatible with newer PDR series subs also.

Edit: It takes awhile for Paradigm to update info on their website.

I'm actually pretty pleased with my response curve. +/- 1.5 dB from 20 Hz to cutoff is very flat. Secrets got +/- 2 dB over that range using the PBK-1 on their Sub 25, and called that "Most impressive!":

My room is 30ftx30ft, so I get fundamental axial modes around 20 Hz. The peak around 30 Hz is the Helmholtz resonance of a hallway that comes off the corner of the room. Any sub location other than directly in the center of the room would excite the fundamental axial modes. Corner placement produced a HUGE peak at 20 Hz that the PBK-1 could barely help.

Bass traps wouldn't do anything to help my frequency domain response, since you'd need traps like 4+ ft deep to provide any attenuation below 30 Hz. In a large room like mine, bass traps are more about improving time domain response ('t60' or 'reverberation time'), which is certainly important, but doesn't show up in a spectral response plot. You'd need software capable of producing waterfall plots to quantify the effect of bass traps, and the PBK-1 doesn't do this.

Did a little more tweaking, and just by moving the sub less than a foot I was able to knock out the ~23 Hz null and the ~30 Hz peak. The peak at ~20 Hz persists, but overall I'm now about +/- 1.25 dB.

My dealer just informed me that the sub 2 is being recalled and further production is delayed due to a "mechanical" error. Addidtional sub 2 s are not due to ship out for another 39 days. Anyone hear of this? Anyone get one of the first sub 2s with problems?

Bummer...

That's the downfall of being an early adopter sometimes. Nice that they found the issue before it shipped though.

I was the 1st one to order the Sub 2 and I am told so far I am getting Serial #1 ( we will see as I was also told I would have my Sub2 a month ago). No Sub 2's have shipped yet other than pre-production models that went to magazines to test etc. So I was told today mine would now finally ship 3/20. I am not getting my hopes up. All I care is they get this product right as it is the final piece in my Signature top of the line setup (S8's, C5, ADP3's, D2v, P5, A2) and want it to be as amazing as the rest of the setup.

i was told the problem is with the software.

I am not sure what thread to go to. I have a paradigm pw-2200. It started crackling yesterday. I have it hooked up to denon 3808ci. I also tried it with my system in the back room(onkyo 606) and it did not make the crackling sound. I also plugged the sub into an outlet without connecting it to receiver and it still made the crackling sound. I do not know why it did not make the sound while hooked up to the onkyo. I have never had this issue, nothing has changed, and never had a problem with ground loop. Any suggestions as to where to go or what to do would be greatly appreciated. I would imagine it is blown, but do not know. Thanks in advance.

That is one amazing setup right there! I am running something similar, although a little smaller scale. (S2's, C3, S1's, Sub 12(x2), 3808CI, A5) I'm very happy with my setup as is, but I dream of a Sub 2...

Btw, what are you currently running for a sub? And, how big is your space?

Currently I have a Klipsch RT-10d Subwoofer. Bought this thing before I really knew what I was doing in terms of audio equipment. No idea how this subwoofer rates but it does the job for now. Picked it up for half price 2 years ago so no big deal and plan to use it in the back of my room as a 2nd sub (not that I will need it with the sub 2).

My room is a typical Arizona style great room (kitchen, living room, dining all in one). So about 1000 - 1200 sq ft. I know it seems like a big system but the overall presence and power of this system is something to experience.

I just ordered a SUB 2 as part of a complete S8 system. The salesman said the reason the SUB 2 has been delayed is that it failed CSA safety testing. Their concern was due to the high currents passing through the voice coils; if a child were to puncture the speaker they could come into contact with it.

Personally I think the safety issue is overblown. If the child is holding a toaster oven or a tea kettle and is properly grounded they will probably be OK.

The solution they are implementing is to make the speaker grills non-removable. This would explain why none of the SUB 2 product photos on the Paradigm website show it with the grills off.

My dealer just got off the phone with Paradigm. He says they are expecting to start shipping the SUB 2 at end of March to early April. If they are available sooner they will let us know and ship mine accordingly.

Same story I got.

May I ask how much both of you purchased the SUB 2 for?

North of $5K maybe $6 since its a brand new to the market product generally getting dealers attitudes to discount them less.

How dare you ask such a rude question!

I won't say it would only expose me to ridicule form DIYers and better negotiators.
