If you have a MacBook try REW, Room Eq Wizard, to have a look at what is going on with your speakers / room... Next, you might try Audirvana to stream from your MacBook to either DAC you are looking at... Audirvana with AudioUnits software plugins will do PEQ etc... REW can generate room correction PEQ filters and Audirvana via an AudioUnits PEQ provide the EQ for your setup... REW and AutioUnits are free and Audirvana is a reasonable price... And I agree, room acoustic treatment first then additional EQ if needed... Use REW as your eyes and ears before and after treatment...
Final piece of the puzzle: digital correction in a suboptimal room
Hey guys!
I’m in the process of upgrading/tweaking my system and there’s one "final" piece of the puzzle I need to find.
Current setup:
- Speakers: Klipsch Forte III
- Subwoofer: Klipsch R-115SW
- Amplifier: Hegel H190
- DAC: Chord Hugo 2
- Room size: 4*5 meters (roughly 13*16 ft)
- Four wall-wall corners treated with GIK Tri-Trap Corner Bass Trap
- Two front wall-wall-ceiling corners treated with GIK Soffit Bass trap
- Side walls, rear wall and ceiling early reflection points treated with Monster bass traps
Considering the small size of the room and the big size of the speakers, I reached the conclusion that a quite heavy acoustic treatment was needed for both bass and mid high early reflections (as you can see from all the acoustic treatments in my setup). I’m still waiting for the panels to be delivered though (looking forward to!!).
My next move would be that of using digital correction as the final tweak to reach a flatter frequency response curve in my room (or at least in my listening spot). But how?
Few considerations:
2) I’d like to have only one digital-analog conversion (carried by Hugo 2)
3) I don’t have a clear budget. I’m willing to spend money if the solution proposed solves my pain in a elegant way. Say 2000 usd max?
Questions:
- What DSP device/software would you suggest me to get?
- The Klipsch Forte III frequency response: 38Hz – 20kHz (+/- 3 dB) How should I cross over to the subwoofer? At which frequency? At around 40Hz, 60Hz or 80Hz? And why?
- Where should the subwoofer fit in the chain in a way that it gets its input signal converted by Hugo 2?
- But then, if I place my subwoofer after the DAC in the audio chain, will the DSP device still be able to control the sub’s input signal separately from the Forte speakers? (so that I’m able to have control on crossover points between speakers and sub)
- BONUS: It might be nice to have a system where I'm able to stream wirelessly from iPhone/Macbook (Airplay, Aptx) to the whole chain. Maybe a DSP device with integrated streamer? (furthermore consider that the Hugo 2 is able to do that via bluetooth aptx and the amplifier Hegel H190 is able to receive through Airplay and bluetooth aptx)
Thank you so much guys for your help!!

@jtcf I’m definitely evaluating the decision of getting more subs. One of the next steps :) @three_easy_payments: yes, you’re right. I’m just in a hurry to reach audio nirvana for my room :D And I know that the odds of getting perfect acoustics even AFTER the placement of the treatments are against me. So I kind of know that I will end up anyway playing with digital room correction eventually. Guys, I took a look at Minidsp offerings with Dirac software and I found that the SHD studio might be the missing piece: https://www.minidsp.com/products/streaming-hd-series/shd-studio https://www.youtube.com/watch?v=zr_oqF9jb-8

I'm realizing now that... I have a spare Chord Mojo! I can use it as the second DAC to give that analog signal needed by the subwoofer. Does it make sense? The Mojo's got two 3.5mm Headphone Jack outputs. So basically: - Chord Hugo 2 giving analog signal to the Hegel H190, which drives the main speakers Forte III - Chord Mojo giving analog signal to the Klipsch R-115SW active sub - Both of the DACs receiving equalized digital signal from the SHD Studio Is there a way to make this happen? Something that connects the Mojo to the subwoofer? So right now I have rca male-rca male cable for connecting the sub and the amplifier. I would need a jack 3.5 male-rca male to connect the sub to the Mojo. Maybe with these? https://www.amazon.it/metallo-masch....gateway&sr=8-8 https://www.amazon.it/Igreely®-pres....ateway&sr=8-10 Not sure about the quality though... |
Try and use something like ROON with built-in DSP in the software. The DSP in ROON is not the greatest but it is evolving with every software release. https://roonlabs.com/ Also look at the Anthem STR preamp which has a highly rated ARC3 DSP and also sub management. https://www.anthemav.com/products-current/model=str-pre-amplifier/page=reviews So there are now 2 choices for DSP in the above 2 recommendations. You are still going to need a streamer to get the music to the preamp/DAC so look at something from Sonare for high quality at a reasonable price. I use a microRendu and it is on the lower side of the Sonare product spectrum but still rather good. Sonare products are ROON endpoints. You would install ROON server on your MAC and use iPhone, MAC, iPad, Android, etc.. as the client to your audio files and streaming services via ROON. https://www.sonore.us/ |
