DSP any Sub for $60! DSP-LF First Look

[@Toid]

Buy the DSP-LF: bit.ly/dsp-lf Turn those 3.5mm to RCA: amzn.to/3ayysek

[@pliedtka]

Yes RCA outs would make it a very good product, 100 percent agreed. I really dislike 3.5mm plugs, noisy, the connection wears out with time, should be baned from normal audio equipment other than portable devices.

[@ziggy8757]

i would say a complete review/tutorial for this unit is a must...if this does what it promises in a good way, itll be a must have gadget....

[@thatotherboi8044]

Ordered mine in march. coming in today I'm so exited. My dad got one the first day it came out and actually got it on time. The results were insane, so I cant wait

[@syedzgaming]

hey how does it work

[@carlyork355]

How well is the signal from 10-20hz? Trying to cheaply put a low pass on a bass shaker and some gain at the lower frequencies. New to all of this.

[@markushjelm6684]

I did buy one for the subwoofer in my office, works really good!

[@garyharper2943]

Works really well.

[@HPMIKE55]

@123Toid Great job bro & if I have a powers speaker and 2 subwoofers would I need 2 of the DSP-LF?

[@TheFrugalAudiophile]

By the time you buy the adapters and the app you can just about get a mini DSP 2 x 4 and I feel like that would be a much more powerful unit.

[@Toid]

That is a good point. You're around 75 to $80 once you do that. The mini DSP isn't that much more.

[@TheFrugalAudiophile]

123Toid And I think I would rather have the mini DSP. Maybe the next version of this device will be more competitive.

[@Toid]

@@TheFrugalAudiophile The one advantageous has is the autotune capability. That's one thing I don't believe the mini DSP has yet. Gray said I do like how the mini DSP is compatible with REW.

[@TheFrugalAudiophile]

123Toid Yes, that is one feature this device does have over the mini DSP. It is nice that you can use our EW with the mini DSP though. In order to get auto calibration with it though you have to spend nearly $400 to get DIRAC On the 2 x 4 HD.

[@Toid]

Let me know if there is anything you want me to test on the device for the review

[@2wilbster]

Will this work on two subwoofers or only one?

[@Toid]

@@2wilbster there's some discrepancy in this. It should work if you have two of the exact same subwoofer, but it will be using a combined response. However it's not intended to be used like this way. I'll have to see if I can test that for you guys.

[@uncola6028]

in addition to your home theatre subwoofer, maybe you can see what the autotune does for your desk subwoofer, that little 8" one

[@denseleit]

So how do you use this if it's connected by bluetooth and my music is also streamed via bluetooth? Nobody mentions this??

[@nizzalotti]

Could I use one of these with a full range input say from a tape or pre out to control a pair of bass woofers in an open baffle set up? Or is it only for a LF sub output from an amp or receiver?

[@Night_Watch413]

Can't wait to see your thoughts and results, and my only thing is if I would need two of these? One for each of my subs.

[@Toid]

Yeah. I think that's the sticking point right now. From the people I've spoke to, you can use it for two subwoofers if they are the exact same. I'll look into testing that. Are yours the same or different? I'll ask around and see if I can come up with an answer.

[@MrBrymstond]

Are your subs wired in stereo? If so yes because some producers pan their subs left and right when they really should be dead center.

[@Night_Watch413]

@@MrBrymstond no I run my subs mono.

[@Night_Watch413]

@@Toid yea for the ones I want to use it for they are both the same exact model.

[@MrBrymstond]

@@Night_Watch413 You should be able to T into them.

[@lenso010]

can you adjust phase at 90 degree .

[@vusstoppyv4612]

Now a full frequency dsp box needs to be made. I have a DA DSP-408 4x8 $130

[@TJ_1999]

That's almost what I was looking for! Does there also exist one for the full frequency range?

[@Toid]

They have this: bit.ly/dsp-408 and mini DSP offers this: amzn.to/346TTk3 but neither have an auto tune function.

[@BiffTannenBTTF]

This one or the OSD dsp??

[@HifiVega]

This is an interesting little piece for sure

[@Toid]

Yeah I'd be interested to see how it would work in a SQ vehicle.

[@HifiVega]

123Toid for sure

[@bertramhvillum1728]

What are those yellow speakers and what drivers do they use?(love your channel)

[@Toid]

Those are the Uglies. I'm going to have a video out on them by Sunday this week. It'll have all the drivers and everything listed.

[@Kcducttaper1]

I love how this video has more views that PE's video releasing it!

[@Boogerweldz]

Besides an auto tune function I wonder what you’re really missing on the $85 open minidsp2x4 bare ‘kit’ version? We can consider the cost the same once buying cables to adapt 3.5.

[@Boogerweldz]

And since the Dayton is backordered indefiniteky(4/29 has changed from 5/29 but that looks to be changing to?? While minidsp is currently available now).

[@Toid]

@@Boogerweldz that's a good point.

[@JMJM75257]

So I just ordered this DSP and I have a couple mono 3.5 to single phonos laying around but I noticed you used a stereo version. Will the mono ones work? seeming as I'm using smsl sa300 and the sub out is only mono I think.

[@Toid]

I haven't tested it, but I can't see why it wouldn't

[@JMJM75257]

@@Toid I'll give it a goo and feedback in the comment section

[@anandshah71]

It would be great if u can 1 more video on its auto correct functionality and your feedback also controls on iOS If u have used. MiniDSP 2x4 what diff u feel is between them cause at 2x4 kit is under 100 buck and manages 4 subs

[@Toid]

Yeah the MinisDSP is awesome, especially at it's price point. I will do a full review. I just want to get someone over here with an iphone, so I can compare and contrast the Android/iphone experience.

[@syedzgaming]

I think with mini dsp u can calibrate 2 subs, with this you cant.

[@vipinsingh5084]

For a global audience, can you create a speaker build video from the part that is available on international shipping companies (like Ali express etc )? We don't have access to Dayton audio or parts express dot com.

[@Toid]

I'll have to look into that for you. See what all AliExpress has available

[@vipinsingh5084]

@@Toid Thanks

[@rusilver2]

i think its more auto audio intended but pretty cool

[@roygriend5143]

For 30$ you can get this one DSPB-K DSP Kernel Board With RCA

[@Toid]

Those are awesome boards! As long as you have a computer with sigma studio (free), that's a great option. I actually have The in circuit programmer and one of the DSP boards to mess around with. Great tip! Thanks for sharing.

[@TheTrueVoiceOfReason]

I didn't see it on the iWoofer page, but I wonder if it will accept a calibration file. If it does, you could use an iMM-6 www.parts-express.com/dayton-audio-imm-6-calibrated-measurement-microphone-for-tablets-iphone-ipad-and-android--390-810 and the problem would be solved. Well, except for porting the full version to Android... That's the mic I got over Christmas. I'll let you know how I like it when I get it set up. "But that's another $17!" "Yeah, but I saved $400 - $700 by not buying an Apple."

[@DescartesRenegade]

a few things. Those RCA 3.5mm likely measure just as well as any "high-end" option you seek out. 2nd, the reason why one is right angle is to allow options for the user, better to have one when needed that not have one at all. 3rd, the reason why its male ends is cause many people would leave the dsp unit by the sub, which would go right into the FEMALE RCAs on it. 4th, having a single RCA input would require the user to acquire an additional L/R combiner, a proper one, not just a Y cable.

[@Toid]

It doesn’t make any sense to use 3.5 mm when all of your audio equipment uses RCA. From your receiver, you have a single RCA labeled a low frequency effect (LFE) output for a subwoofer. Your subwoofer also typically has one single RCA input for LFE. No, it doesn’t really matter if you have the DSP close to your subwoofer or your surround sound receiver. No matter what you’re going to have to convert that RCA to a 3.5 mm cable on both ends. It just doesn’t make sense to make it a 3.5mm on the unit and definitely not a 3.5 mm stereo cable since you’ll need to in most surround sound environments change that to mono. it would make a lot more sense to just have two female RCA ports. That way you can just run an RCA cable from the back of the surround sound receiver into this unit and then out of this unit to the subwoofer amplifier. There might be some cases where a 3.5 mm is more appropriate, but for normal surround sound use it’s not..

[@DescartesRenegade]

@@Toid perhaps they wanted to keep the footprint of the device static and left no room for RCAs on the PCB. I know it doesn't matter where you keep the dsp, but I, and probably many others, would just leave it behind the sub. This thing isn't just for home theater usage with LFE, they also made it for those who are 2.1 or 2.2, like me. Why handicap the product when all it takes is to allow for integration of a stereo signal with a 3.5mm jack? I'm not some audio guru, just an engineer who understands the manufacturing process of devices like these and to make it as flexible as possible to the broadest user base.

[@Toid]

@@DescartesRenegade that is a good point. The only issue is the application only works with a mono subwoofer. So even if you do use two subwoofers, it’s going to DSP them as one. So you won’t be able to properly get the delay between the two subwoofers, correct. And since it doesn’t work for stereo speakers, but it’s designed for just subwoofer application, it doesn’t really make a lot of sense to make it stereo. The only real application I could see someone using two outputs is if the subwoofers are directly next to each other. Or if you use a stereo amplifier to power your subwoofer. Then in that case you could use really any amplifier you want and just use this for your high pass and low pass. Although once again, you would probably only be using one output on the amplifier, so that probably wouldn’t help either. Either way, I think you’re right, they did it mainly to keep the small footprint.

[@DescartesRenegade]

@@Toid but what if I want the sub to be as flat as possible to fill in the 2ch low end? Sure, the delay wouldn't be exact, but still better and FR can be flatter

[@Toid]

@@DescartesRenegade you’d be better off getting a mini DSP, and using some thing like multi sub woofer optimizer in conjunction with a measurement mic.

[@jondoe6618]

I seen this the other day. I thought that is cool. THEN no rca's. I would of bought it.But 3.5 splitter cables are JUNK!

[@Toid]

I would rather RCA's as well, but I use these, which works much better than a 3.5mm to rca cable: amzn.to/3ayysek

[@thatotherboi8044]

Why though? Unless your situation is with extreme noise, it will probably be fine

[@tommuendo3462]

Hi guys does anyone know how to remove humming sound from the dsp lf

[@Toid]

There shouldn't be any hum. The only reason why you'd get a hum is if there was an RCA end that wasn't connected to anything. So for example if you use a 3.5 mm to RCA cable that was a stereo cable and one of those ends is not hooked up... You could get a humming sound.

[@tommuendo3462]

@@Toid am actually using the 3.5mm to RCA that is supplied in the box. Could it be the power supply? Few days ago i realized the one supplied was not working so i looked for another 5v 100ma charger. I have tried several other ways like getting power supply from my receiver, tv and even wifi router. All the above power the device and it actually works but the humming sound is still there

[@RennieAsh]

Worrying about the cables lol you can buy nice 3.5mm to RCA cables. If it had RCA it would be twice the size probably. And because it's a value unit, then you'd have to complain about the "cheap RCA terminals" on it

[@jonfoss3437]

How do you connect the damn thing to android. ?????

Dsp without auto tune and rca = junk. Do not buy this crap just because this guy tells you to.

[@Toid]

I'm guessing you didn't watch the video. This does have auto-tune. And it's pretty easy to convert to RCA like I said. I also mentioned that not having RCA was one of things that I did not like about it.

[@RockFordCademce]

@@Toid Does it have auto tune if you have to make friends with somone at starbucks who has an ifruit to use the auto tune function? Come on. I like your videos but you telling people to just buy this thing before the review..?

[@Toid]

@@RockFordCademce yes if it has auto-tune. And I tried to make it as clear as I could, that needing an I device is one thing that I really don't like about it (I plan to go into further detail when the actual review comes out). But what I really want to clarify, is that I am not telling anyone to buy this. All I said is if you wanted to buy it, you should probably put an order in while it's on back order. I didn't go into great detail, but the thinking behind that is, as soon as that stock goes out again, who knows when they'll get another batch back in. With coronavirus affecting shipping times so much, It's anybody's guess on when they'll get more stock in. I really wanted to have this reviewed already, but I'm trying to hold off on doing a review until I can get someone over here with an iPhone to give it the full run through.
