MF M1Clic - Adding Velodyne sub

Hi all,

Hope you are well. I am not an audiophile but an audio enthusiast. Would appreciate your guidance on a query below. To date I have assembled a system based on my ears (listening taste) but going forward need help on the technical side. I was considering adding the the Velodyne digital drive plus 10 inch powered sub to my existing audio set up. Please could you help me on how should i set this up. My current set up is as follows -
-Dynaudio Excite x36 (2 passive tower speakers) (,
-Musical Fidelity M1 Clic as preamp and source (
-Musical Fidelity M1 Pwr (powered amp in mono mode for driving speakers - bridged speakers) (
-Atlas and wireworld power cables & accessories

As you can see from the above, i am trying to add a sub to a setup that is predominantly set up for stereo system (2.0). The amplifier and the preamp do not have dedicated line outs for a sub. I need to be creative here and get the best of the system. Please could you answer my queries below.
a) Please note i have chosen the sub based on my room dimensions and reviews, if you think i should add a different model please let me know
b) Is the setup optimal given the music equipment; i.e. do i need to add receiver or speaker splitter box
c) The sub has several inputs/outputs, please could you help me assist on the best way to leverage the sub capabilities
----Should i chain sub and speakers
----I was hoping to use RCA splitters at the M1 clic (preamp)
d) Could i add the Wii connect system to get some flexibility
e) Given my speakers what levels should i set up my crossover and volume
f) Any other consideration that I need to understand

Thanks a lot in advance. Please drop some web links to the items / connectors / splitter boxes that I may need to buy off amazon or your vendor references.

It's impossible to tell simply by reading the specs but your amplifier appears to be underpowered for your speakers. If that is the case then Bob has given you some important advise to consider.

The DD-10 Plus is a very potent sub with far less distortion than its already low distortion predecessor. It has many connectivity setup options which are located in the User Manual.

For an economical pair of long run RCA interconnects and Y connectors Blue Jeans Cable offers decent quality and fast delivery.

The User Interface manual goes into detail on how to use the Manual Room Optimization program which can also be found on the Velodyne website. These adjustments are straight forward. On the other hand you may find that relocating the sub and/or tweaking the adjustments over time can further the integration with your speakers and/or the room.

You should set one of the presets to 180 degree polarity since many recordings are out of phase and you may hear the bass drum tighten up.
While it can certainly be done, the MF is probably less than ideal for the application you seek.

If you can locate an NHT X-2 (no easy trick, since it's been discontinued for a while), it will allow you to implement the arrangement that Bob recommends (and which I also recommend).

However, it looks like all your source material is digital. In this case, I'd always choose to integrate the sub in the digital domain with bass management software like Audyssey (or similar). The room EQ piece of the digital bass management software is included in the Velodyne DD subs, but - unless it's been upgraded in recent years - it's not a very elegant version of this approach. And, as Bob notes, you're locked into a low-cut function for the mains that's often suboptimal.

OTH, Audyssey xt32 is IMHO really, really good. It's commonly found in upper end AVRs and multi-channel pre-pros, but a similar solution (from Cirrus, not Audyssey) is also available from HK in their model 990 integrated. The Cirrus multi-channel chip has gotten mixed reviews, but I thought their 2 channel chip worked well in the HK when I heard it.

Good Luck.
I'm not familiar with your equipment, but on paper it would seem you have what you need for 2ch listening. Speakers go down to 35 Hz. Mono block amps put out 200 watts into 4 ohm's. You should have plenty of bass, unless you listen to organ music or you like the bass artificiality enhanced. What don't you like about what you have?

I use 2 Velodyne DD12's with my monitors. I'd have to respectfully agree to disagree with what was said above. They're not that difficult to integrate. But again, why bother?

I get great and plentiful bass from my trusty old REL 10" sub that goes down to 25 hz or so in my medium largish room, proving that indeed you CAN get great bass from a 10 (I use 10's in my pro bass playing rig also). Not sure if all 10s work this well, but plenty of happy REL users like the way these integrate with mains that remain unfettered with filter fettering folderol using the "high level" input on a REL. My only experience with Velodynes was a 15" servo thing many years ago, and that worked well also. I don't think digital bass management nannys are always necessary as all they do is compress and ride the bass level, although I may be a minority in that opinion. just gets too damn fussy...

"Room mode correction doesn't compress bass except in those instances that it is unnaturally elevated due to the physical dimensions of the room"...meaning it doesn't compress until it does?'s "smoothing" by compressing and limiting...that's what they do...the "room mode correction" gizmo decides what bass peaks are going to offend the listener and limits them, because, as we all know, ears should not be trusted. I need a "provincial Church Lady" correction device to use as a forum response nanny.

Also, I suppose I should have said "great SOUNDING bass" (!), because that's what it is, and distortion levels below the 55hz or so where my REL is active (especially since I never tax the thing with excessive level) when measured by measurers is irrelevant if inaudible...proven all night. Room correcto no, distorto minuto no problemo.
Hmmm, seems like we've scared the OP away with all this "technical" stuff :-). As a self proclaimed non-audiophile who's probably not looking to tinker til the cows come home, it was my initial thought that he (or she) already has what's needed for 2ch. listening. Come to think of it, that's still my thought.

I've heard room correction systems and I think they are for people who lack the ability to set up hifi systems or prefer digitized and flattened bass response...that's hardly natural. I prefer to not use a digital nanny in my room but clearly you do in yours, and why would I care? I've been a successful musician and a live sound mixer/recording technician for decades and know exactly what "natural" sound is, and the bass in my system is not "lumpy or unnatural" because I wouldn't put up with that, or with what you claim is audible distortion in a system you haven't heard. To assume any room that doesn't use a digital nanny has bad sound is a weirdly self aggrandizing stand to take, and oddly point is merely that you don't need to buy into what somebody in a lab coat says you need...or maybe you do!
To see if I'm a Luddite or simply an Actual Expert (heh heh), I did a cursory scan of audio reviewers in my pile of gear rags in my recycle que, some reputable, some arguable, to see how many are regularly using any sort of the aforementioned "Digital Room Mode Sonic Nanny/Babysitter Bass Controller Limiter/Compressor Robot Gadget"...and found the number to be zero. No nothin'. Perhaps I should have searched harder...but If these things are as magic as some say, one whould think the Audio Illuminati would have universally adopted 'em...but, sadly (for the Asian slaves toiling away making this stuff), they have not.

I would have to agree with Marco...the law of diminishing returns is very evident when adding bass to already full range my experience the extra cost, time, and end results were counter productive...Dynaudio is a quality product with sufficient bass for most applications...smaller speakers obviously can benefit from a sub...but I always have admired the slim tower design...same footprint as monitors with stands...with much improved bass response...and still very good imaging...
,however...the addition of a sub can be most advantageous if the source material warrants electronica, organ, reggae,etc
A good sub can charge the air in a room and make your mains seem to be working better even when listening to mandolins. A bass guitar has a low E of about 41hz and an experienced listener with good speakers can easily tell if it's an upright or a Fender...easily...take that, Dr. Toole! Carpet or rugs and all your crap and furniture will work wonders to tame a room and that, speaker placement, and keeping a sub level in control are all you might need for non lumpy sound. If that doesn't work you can nail mattresses to the walls, or give up and buy a Digital Nanny.
Also...lets face it....subs are complicated...they take tweaking/tinkering...and in the hands of the inexperienced...can cause more harm than good...just my .02...
I like the roomacoustic sytem of Velodyne a lot. I think they are great for surround as well. But in speed and in what I call stealth integration there are better ones. For stereo use timin is a very important matter.

Thanks for all your input. You are all very kind. Apologies i was away on travel and am looking at all the msgs. Let me start by giving you a basic setup on the listening room and answer Bob's question.

-The room is shaped like a square with a triangle on top. i.e. total of 5 walls with one side open; something like the figure below


The measurements of the walls are as follows (in feet, H x W)

1. Wall behind the couch (10.4 x 8.6)
2. Wall behind the TV and wodden cabinet (10.4 x 11.0), depth of the wodden cupboard cabinet (2.5)
3. Wall next to the wodden cabinet with large windows (10.4 x 9.0)
4. Wall next with 1 window next to couch wall (10.4 x 9.4)
5. Distance between speakers and couch - (7.10); distance between the speakers (6.7)
6. The open side wall is has space of around 4 ft

For all the help; i owe you guys a round of drinks when you are in Sing next. Please look me up, if are in this part of the world. Thnx

That's a pretty deluxe cell for Sing Sing.
The biggest reason for me considering adding a sub was bass. I listen to a lot of progressive house music and though the Dynaudio speakers are full range I'm not happy with the bass. I prefer a simpler solution (maybe bass management hardware) that's why I zoomed in the velodynes given auto eq and optionality on the connections. I don't see me changing the current set up (MF amps or speakers) despite the shortcomings as I like the sound. Welcome thoughts and other ideas. Thnx ameet
There is a lot more information on every recording. With a sub you get more ( extra) information. Since more than one year I use my subwoofer from 16-140hz. Bij using it till 140hz the level went even higher. From 80 hz low freq become touchable. Using it till 140 hz instruments and voices are sharper focussed.
