MB Quart Vera VS1SW or SVS PB-2000 or Dayton DIY kit?

The nice thing about a passive radiator design also is the fact that it sounds more like sealed, since it is effectively a sealed sub, but gives you somewhat greater output than a straight sealed configuration.

I've never heard anything with a passive radiator, so it's good to see an opinion other than "reflex port for pretentious people". I know avoiding port chuff would make a passive radiator superior to a tuned port, but I inferred from others' opinions that the net result would still be a speaker with louder volume but perhaps a looser Q and less definition.

Back to an unanswered question, does anyone have an opinions on the DSPeaker anti-mode devices? I emailed Tim Ryan at simplifiaudio.com, who tells me their stock of discontinued 8033C are reduced to $295. They've only got a few left though. From what I can gather, it's sort of like miniDSP but only for subwoofers, with an automated setup similar to Audyssey. It'll flatten humps but won't boost dips, although it does provide an overall 3dB gain as well as a selectable bottom boost.

Passive radiator sub's can be nice. And sound great. They're not the be all end all though, and they have their own tradeoffs.

Skip the antimode. If you don't want to out in the time, just make sure you have a receiver with audyssey. If you want to put a little time and effort in, go with the miniDSP.

This is my buddy's old enclosure that I turned into a "Franken SVS". It was an older SVS Plus driver with a GR adjustable PR and a Rythmik non-servo amp. The thing was pretty nice; not as much output as the PB12 Plus and not as clean as my Empire, but a good blend between both output and SQ. Only had it a few weeks before selling it.

...considering you can get a pair of these puppies plus an amplifier for less than $1,000, it is as you say, a great value.

iNUKE3000 (over 800wpc into 4ohm), 3 year warranty at $230 sale price - one might be temped to go for it regarding of the behringer questionable quality reputation....
Just add ether AVR with SubEQ or minidsp w/ mic

Or for $50 more one might find the same amp with an added DSP. You're limited to 8 points on its parametric EQ; but page 13 of the manual hints that you can define your own frequency and width / slope for each point. I'd be interested in having someone who owns this amp verify this assertion, though.

Hey, anyone know of a decent amp with a signal trigger input to sync its power state with my receiver? Or is such a thing generally limited to plate amps such as what SVS uses?

You can get a plug strip with a trigger. PE also offers what amount to stand alone plate amps, though not sure if those are going to be something you'll be interested in.

Good idea. I just picked up a Niles triggered AC outlet on Ebay for 60 bucks. I feel like this opens up a world of possibilities for me.

I also found an Emotiva monoblock and a NAD stereo amp with triggered inputs. I also saw that Dayton, which I was thinking might be more bulletproof as a class AB amp than the higher wattage but feather light class D iNukes and Behringers. Then for a while I considered getting a car subwoofer amp, a 1 farad cap and a PC power supply to use. But then I started adding camouflage paint, fiber optic Jesus paintings and deer antlers to my shopping cart, so I just had to back off for some perspective.

Oh, I forgot to mention, your FrankenSVS is beautiful! Very nice work on that cabinet!

True enough, but with miniDSP and REW the integration is really bullet-proof. With Behringer DSP and it's capabilities in question, I wouldn't take the chance over $50-70
Besides minidsp could support 4 subs even in the cheapest model.

The Anti-mode actually works pretty good, and is about as simple and easy to use as any device you'll likely ever encounter. I never thought the price was an accurate reflection of the product though; it always struck me as high for what you got.

IMO its extremely high for what you get.

Well, yeah, I can see that from a tangible component perspective. It's basically $40 worth of hardware with expensive firmware.

On the other hand, consider the minidsp. It's about 200 bucks once you add an app, a mic, and a power adapter. Using it requires a lot of effort and hand holding, and you only get 6 nodes for eq if you opt for the mostly auto REW integration. Manual eq of up to 32 points is available, but setting it up isn't exactly quick and easy.

Whereas for 100 bucks more, the anti-mode 8033c sets a 24 point correction automatically while you go have a cup of tea.

The superiority of the minidsp becomes more apparent when a user is tweaking multiple subs. The anti-mode only works on a single sub as I understand it. But since single sub users are DSPeaker's target audience, I think the price is reasonable for the benefits gained.

But I agree that the anti-mode doesn't do anything that Audyssey doesn't also do (perhaps better) for people with an Audyssey capable receiver.

Don't forget Audyssey dual SubEq - it's makes dialing dual subs super easy and very accurate, the issue is price. only mid-end to hi-end receives have it (not all Audyssey XT32 have it by default)

IMO, REW and miniDSP only need a lot of hand holding if you can't read the extensive REW manual and resources that are available. Also, for me in my room, with my equipment, their top of the line model (antimode dual core 2.0) didn't outperform Audyssey subEQ and fell well short of me + REW + miniDSP. Based on my experiences with it, buying a good receiver is a better investment than buying a low level receiver and then adding one of the anti-mode devices. The big upside to the anti-mode devices is that you can upgrade other equipment while keeping it and your settings.

Another point I'd like to make is that with the 8033, it has no screen, nor does it allow you to see what it's doing. So there's no way to verify what has been improved or what has been done at all.

 

[Jcharger13]

OP, did you ever decide on a sub? I've been kicking around a few of these options myself when I found this thread.

Mini dsp, crown or behringer amp (or an amp with dsp capabilities built in) with my JL 12W7 that's laying around here not being used, would be sealed (mainly for music and already have a box). The MBquart sub. Possibly a pb2000 or xv15.

 

[rojo]

Well, an unexpected emergency killed my plans unfortunately. I'm going to have to hang onto my current sub for now. I was mostly leaning toward the SVS SB2000 though. The Quart is very interesting, but information on it is too scant for me to take the gamble. For example, as far as I can guess from looking at the amp panel, it's probably non-defeatable auto on. I'd rather use my receiver's 12v trigger out or my Niles triggered outlet to handle the auto power. And DIY sounds like a great value, but thinking about it just makes me imagine a big hippie mess. Since I'm not trying to pressurize an auditorium, I think a 12" sealed sub would be plenty for my 2400 cu ft room.

 

[Jcharger13]

Sorry to hear that.

I can tell you that the SB2000 does pretty well in that size room. I'm running one right now in another room that's around 2300 cu ft. After I got the placement nailed down it has decent extension down to 20 hz with room gain helping bump the low end. Definetly worth a look.
Was kicking around buying a second but always like trying something different out.
