Looks like a very affordable and robust alternative to the miniDSP. Great job Joe and congrats again on the new house.

[@shaunvickers9255]

This is a great simple room correction option for people who don’t want to replace their existing systems just to add bass management!

[@OHMAudioChannel]

Hopefully OSD / REW are able to get an Equalizer preset into REW filter settings. That would take this product even more compelling.

[@ErinsAudioCorner]

Cool little product. Congrats on the new crib!

[@tejfilms5801]

Extremely exited joe!!! As always 🔥 Enjoy your new place!!

[@juanmillaruelo7647]

Congrats on your new house, Joe :-) And good video, simple, to the point, ties everything together: room response, listening point, REW, curves and their compensation. Lots of people are going to give it a try. Most everyone either lacks or has a surplus of bass or treble. DSP EQ can help (with your video). :-)

[@xsonicpunkx]

You are the best of them all In my opinion. Everything you review and walk us through is something I can afford and need. Some of the other “you tubers” review way to many equipment that I can only dream of in another lifetime with price tags over $4000 per speaker. It’s nice to dream big but most of us like to see reviews on equipment that is reasonably price and that I can someday add to my collection. Thank you Joe

[@kewlbug]

Normal guys looking at maybe $100-300 a speaker, enthusiasts maybe $800-1000 a speaker, and then certain you tubes where all they talk about are these $4000-10000 speakers and $5-$10k processors, etc.. tone deaf to the majority audience. Well past the point of diminishing returns IMO. Maybe they're fine with that Niche. But I'm looking for affordable solutions such as Dayton subs, Behringer amps, and MiniDSP.

Thanks Joe, very helpful info.

[@techhobbymk2305]

iDSP has 2V output and you can use SMC21 from OSD for Stereo-mono connector.

[@kewlbug]

I like sweeps and the alignment tool in REW for phase. also set peq with the main speakers off. Example, You might have a random bump from the subs at 120 or 140 or something you have to knock down. Even with a crossover active.

[@TheoneDragon51]

Congrats on the new house man!

[@TheoneDragon51]

I hear some room treatment needed!

[@joentell]

More furniture and thick rug/curtains first. No need to jump to room treatment right off the bat.

[@steakhoux]

Hello Joe, when you apply symmetric XO filters you don't need to flip the polarity. This would mean 24 db per octave for the highpass and the lowpass. A 12 db per octave XO filter alters the phase by 180 degrees at the XO, a 24 db per octave filter alters it by 360 degress. That's why one often has to flip polarity. The phase adjustment of the iDSP is probably an 1st order all pass filter. It alters the phase by 180 degress at the selected frequency.

[@johnlim7720]

compared to the miniDSP?

[@joentell]

MiniDSP is more robust as the 2x4 can be used as an active crossover or for a 2.1 system. The HD version allows you to upgrade to using DIRAC. This iDSP allows for more PEQ filters and has wireless mobile app control via bluetooth.

[@johnlim7720]

@@joentell Thanks...I do have the 2X4 HD but didn't know that it's Dirac capable..I just took a quick look and saw that its $199 for the software add-on. I personally have no experience with Dirac. Do you think it's worth the $199? Thanks Joe.

Just purchased the Parts Express Dayton Audio DSP-LF. It has a 20hz high pass filter. I am kind of shocked it will not allow lowering below 20hz. Also not sure it is defeat able. We just built (2) 8cu foot sealed boxes with Stereo Integrity 18V3's ($200ea shipped) for behind our couch to enhance 25hz and below. Kind of defeats their purpose using a 20hz Hpf. I have only spent maybe an hour playing with iWoofer but it appears to have some issues actually reducing the annoying node I bought the DSP-LF to reduce. I got a THD error the first wizard I ran. I am going to try to lower to -20db as suggested in another video about iWoofer. I am hoping there is a way to manually lower problematic frequencies in my room using the DSP-LF similar to how I use Equalizer APO on my pc. Anyway, thanks for the video. Have watched it a few times. Your methodology and presentation make it easy to understand and follow.

Cant believe this is $40. Seems like an amaxing option for those who want simple bass management. Im getting one!

[@krishnataveras8734]

Too bad is no longer available. I would have love to try this

[@stckyjoey1]

Hey Joe. I have the Dayton audio DSP. Is that OK for the subs?

[@Sweetaccord]

Yes you can use it for subs.

[@NakeanWickliff]

Well done with the single sub and little time. I thought I remember being told you should never boost eq but should subtract instead. So move target curve down to lowest sub output. Then cut the peaks. This allows for headroom. Have you heard anything like this?

[@joentell]

That makes sense, but I don't mind boosting for subs with protection limiters like these SVS. You have to be real careful with subs that don't. I also don't like doing it for speakers other than the subs.

[@NakeanWickliff]

@@joentell Yeah that makes sense. I have DIY subs with pro amps so I don't have the limiters built-in and 1500 watts RMS on tap. Gotta be careful...but not too careful :)

[@Hypeex]

@@joentell The reason people say don't boost is because you are technically loosing resolution. Think of the scale being 0-100, but you boost it to 0-120 with the same amount of "steps" between min and max. But honestly unless you go crazy it's not audible, so boost on! 🚀

[@denseleit]

They don't list this unit anymore on amazon or their website.. It might be discontinued

[@mladia]

I already have MiniDSP 2x4HD for my subs. Can I use this for my front, left and center (rears?) ? Ooops. Sorry realized you said it is specifically designed for subs. Any other product you recommend in the same price range that will do EQ for other speakers?

[@joentell]

I just reviewed the DDRC88A, but it's pricey

[@mladia]

@@joentell yea I guess I can buy another minidsp 2x4hd but $75 is a great price point

[@amb3cog]

SHS adds bass. It doesn't reduce it. It's used in discos/clubs/roller rinks/fairs for instance. This is why the music always seems to be so pounding at a club, when compared to how it sounds at home. They don't just turn up the bass knobs. They use this trick, because it works better. There are of course other ways it's used too I'm sure, but this is the best way I can think to describe it to everyone. In this particular case at least, it generates sub harmonics at half the original frequency. So a song from say The Who made back in the day that only goes down to 40hz. Will now have extra sub harmonics added at 20hz, when the 40hz keyboards, bass guitar, or drums kick in. So it will have deeper bass now. As it says in the description. It's a bass restoration tool. Either way, try it, and you'll see what I mean. Just be careful. 😊

[@joentell]

Oh yeah for sure. I didn't say it reduces bass did I? I know that it adds "synthesized" bass when a speaker can't play the fundamental tone with authority, it "hints" at the original tone by playing higher order harmonics.

[@amb3cog]

@@joentell No sir. It has nothing to do with what the speaker can handle, or can't handle at all. It's specifically designed for subwoofers that can handle low bass. And besides, that's a separate issue, for the sound engineer (aka you at home, or the guy running the sound system at the club) to figure out separately when designing the system. It's too restore lost bass in old recordings. It basically just adds bass, at a lower frequency then the music currently has. Old music usually got the low end cut off due to the technological restraints of the time. It takes the lowest octave being played, and duplicates it at half the frequency it's playing at. So old music that only plays down to 50hz, will now get those signals in the 50hz to 100hz range re-created into signals that are now 25hz to 50hz and mixed into the song being played. So it recreates the lowest octaves at the next lowest octave. Or about half the current frequency. It started as a way to get the bass left off of albums back in the day. They used them extensively at Roller Rinks, Clubs, Discos, etc. And they were stand alone rack units. Now we can just do it in DSP. Like most everything else. And we don't need it for today's music in most cases, because today's music is all digital, and has a real 20hz to 20khz bandwidth. Old music doesn't have that same bandwidth. So if you listen to old music a lot, and it's sounding too thin for your taste. You would use this to add lower bass, and make it sound more full. It's why music at the clubs is, and was always so pounding, even back in the day when music didn't ever sound like that at home. The difference was they had these units, and subwoofers. Where as the average consumer back then had speakers that only went down to 50hz. Maybe 40hz, if they were very lucky, and installed them in a corner. 😁 en.m.wikipedia.org/wiki/Subharmonic_synthesizer

[@joentell]

@@amb3cog Oh I see what you're saying now! It adds extended bass kind of like the old Epicenter I had in my car audio system back in the day. I confused the setting with some of the stuff Bose does with some of their small Bluetooth speakers to give them the perception of having more bass than they can actually output. Similar mechanics as what you've described but used for pretty much opposite purposes.

[@amb3cog]

@@joentell Yes sir, exactly like the Epicenter does. I forgot about those things. That's a perfect example to use when describing this feature. And yes it's probably very similar to what Bose does, but in reverse. I would actually really like to try this feature myself, as I listen mostly to old music. I'm not really interested in getting subs for my current room though, as it's really too small, and I wouldn't even know where to put one in here. It's packed up with gear already. And besides, even most bookshelf speakers have plenty of bass in it. It's only 12x12x8 ft. But who knows? Maybe someday. If I become a big shot KZbinr, and move to a big fancy place like you just did. 😉 😁 Just messing with you man. Can't wait to see what you do with the place actually. It's going to be fun. Have a great day Joe. 😊 ✌️

Is there any issue to put the DSP before or after a pre-amp? I have a 6vrms out and I spoke with OSD and they say it's fine to feed in that much and won't hurt anything?

I wonder how this iDSP compares to the Dayton Audio DSP-LF DSP Controller? Come on Dayton, send him a unit so we can see a comparison. Agreed, I wish the unit would allow you to enter values numerically as opposed to the pinch and move method which can be tedious.

[@joentell]

I think they're pretty much the same except the connection method

[@C_O_N_C_E_P_T]

For 20$ more a minidsp is probably better?

There are pros and cons to both which I think I addressed in the video. Simplicity + mobile app, vs versatility and advanced features on MiniDSP.

You can “sum” the signal by using a F/F/M RCA Y if you do not have a dedicated mono/sub/LFE output, Keeps the price down. ;)

@@bennyblanco14 He used the Android app as the other options were not available. If he used the ios then he would not need the rew app as the iwoofer on ios has the auto measuring function.

[@TylerStout]

Got my dad the Dayton one and it also uses the iWoofer app, I need to figure out a way to get the biquad stuff that you can export via REW or MSO and turn it into a file you can import into the iWoofer app. The file import/export file is XML if I recall correctly so it's merely just converting the data from one format to another. I'm not sure which I would want between Dayton DSP-LF, iDSP, or minidsp 2x4 (non hd) since they are all $20 apart begs the question of which is best value. Assuming the iDSP is actually 2v for the sub out that would make it worth it over the dayton 1v or minidsp .9v imo but the miniDSP being able to do multiple subs is a big advantage so I'm not even sure.

[@sideeffects6570]

This DSP’s kinda suck TBH. I swapped it out for a ROLLS duel filter cross over . Now I can hit every bass not with authority.

[@jebo4jc]

My mind is a bit blown by the subwoofer placement. "I think it would be good......there." Not even a quick subwoofer crawl? Awesome video nonetheless Joe. I'm still working on getting up to speed on REW but I'll definitely consider this as an alternative to the minidsp. And congrats on the new house!!

[@joentell]

In this room, sound quality is not the priority. Crazy right? I will have a dedicated home theater room for that. Also, the sub crawl is a bit overrated as we know that using multiple subs in optimal locations can help greatly with respect to room modes. Then with DSP, you'll have excellent bass. If you had to guess the best possible way to load the room with bass, the corner is the best place to start.
