I'm hearing this complaint more and more from audiophiles. They have too much bass, or more specifically, too much mid bass. Bass spikes in the 60, 70 or 80hz region can be a real PITA. Being the quirky bunch we are, most are opposed to the letters "DSP". It sends shivers down the spine of the harden audiophile, myself included.

In my own situation, I had a major spike at 73hz in my main listening room with my Alexia's. I also had a similar problem with other speakers in that room. The placement of 10 bass traps did little, if anything to fix that 73hz problem.

I've been living with the DSPeaker 2.0 Dual Core for the past couple of months and this little magic black box works! It comes with everything you need out of the box. It retails for about $1200 and nothing in that price range can touch it.

Downside? A slight increase in "hiss"/background noise.

I believe Jeff from AV Solutions has picked up the line a couple of weeks ago. Maybe he can chime in here.

I also plan on trying the DEQX soon. Stay tuned. The point is, there is a solution!

wow!!! you have 10 bass traps in your room.lol!!! you guys ever think you might be going a little off the deep end looking for the perfect sound? :roflmao:
im sure you have . hahahahaha!!!
i really not even sure what this DSPeaker does? i guess i need to do some research.
too much bass has never been my problem. in my car it is and it hurts my ears.
glad you found the fix mike!

I have had one for a year. The only complaint is that on some recordings, it can takje some life out of the bass foundation. The light hiss may be due to how its hooked up. Do you use Optical?
 
Mike, I picked up a DEQX HDP4 unit a couple of months ago. I have not had time to study the manual and set it up yet. You are welcome to try it out for a couple of weeks if you would like ?? I have been busy with another unit called ConEq, that I have been using on a large open-baffle speaker project. Let me know if you would like to give it a whirl. I could bring it up with the PS Audio Direct Sound DAC, which is arriving on time today (!!!).

Cheers.........Jerry-
 
Yes most rooms have a few bass peaks that create booming sounds. My room / speaker / positioning situation had peaks a little above 20 Hz and a little above 60 Hz as you can see in the spectrum. I used Audionet CARMA software and a measuring microphone with correction to measure this. In Carma I could correct the peaks and transmit the new curves to my Audionet DNP pre amplifier. Result the bass is tight and clean (not too lean!!) and the booming disappeared. Key is correcting with the correct Q value, which defines the width of correction.
I am sure DSPeaker does a similar job. However doing this in the pre-amp's DSP prevents side effects as described by Mike and Norman.

Jerry, I'm as bad as you! I have one in my room now, but haven't bothered to set it up either. It's been here for a few weeks.

Jerry - you have to come down and here the Raidho and Alexia systems.

The Audionet preamp is an incredible piece of engineering. I suspect we may see more DSP built into preamps in the future.

Balance in/balance out Norman. I don't like to bypass my preamp. Gotta have that tubey goodness.

Alexia is extremely boomy. Like.... horrifically so.

I'm not surprised, even with all the bass traps, that you have resorted to the DSP unit you posted there. A lot of good reviews on it for the out of control system/room. Not sure if I like the whole re-digitizing or minor hiss part, but wtf are you going to do to calm those suckers down!?

I know some repositioning and re-aiming of Alexia does help, but sometimes solving that overwhelming bass/midbass wobble seems damn near impossible "au natural."

I feel for ya!
 
My Room is very Small with the speakers very close to the back wall and no Bass problems
Maybe I'm lucky
:)
 
E - I wasn't specifically referring to the Alexia's. I've had bass problems in my room with many speakers. The DualCore for me, worked well. But I'm looking forward to trying the DEQX.

For those of you who are interested in trying out these type of solutions... J River and a number of the other software packages have tools that offer the same type of effects. If you have a digital only system, this may be an easy way to try it out.

One very real potential downside of using DEQ to fix these issues, is that you can only accurately eq for one listening position. Acoustic solutions like using multiple subwoofers allow you to even the power response for a much wider area. Something to consider...
 
I have similar bass gain issues with every full range speaker I have used. No matter what bass traps etc I have used, the room is still the root of the problem.

The Deqx is the best $$ I have spent on HiFi. Use it every day when I play music. Listening to Elvis and alike is fine without eq, however any music with a lot of bass becomes boomy/muddy.

I can play direct ( no eq ), calibrated bass and another 3 bass eq settings that I use depending on the bass output. All from the click of the remote.

No downside from this analog nut with 4 tables.

Very true.

With all the eq devices like DEQX, I felt they removed some of the nuance and added distortion/noise to the signal. I could not pin point the distortion noise until I tried the Lynx Hilo which has 4 channel analog output and an A/D. The Bass eq was done in the digital domain on a computer. The output was then sent directly to the amps. The sound was so much cleaner, it was like I was listening through a muddy window and someone had cleaned the window.

Fabfilter has a great VST plugin and allows very complex notch filters. The Lynx hilo also has an analog input so you can digitize music if you would like or simply do the eq. This will allow to compensate for suckouts as well as bass nodes.

The setup is more complex than DEQX and the likes of eq because you have to use a computer to do the VST plug in and eq. However the sonic benefits were amazing. DallasJustice (on whatsupforum) uses DIRAC which is also very good.


Not all, but most eq's use 24/96 and for some reason have more distortion/noise. This is true of the DEQX (24/96 at least, perhaps not as much noise). The Lynx does the A/D and D/A in 24/192 and has a very clean sound.
 
Not to sound stupid, but how does one know they have, or don't have, a bass problem? Especially at 73 hertz, or some other frequency. Is there an iPhone app for measuring bass? I have the db meter app, but that is just SPL level.

I recently bought a pair of Magico S5s, and I wondered if I should because I kept on reading they have powerful bass, and it can overpower you. Well, maybe they do, but I don't hear it. It is more defined than with the Aerial Acoustics 7T, but certainly not overpowering.

As an FYI, I played these so loud last week the circuit breaker tripped. I suspect it was the bass that caused it, but, while loud, it sounded good.

Not sure it if accurate to lump Deqx into all eq devices.

The DEQX speaker correction is proprietary, there is no one else doing it. It is a unique low latency FIR filter that corrects for both frequency and group delay. It also does DSP speaker crossover and room correction.


Can't say I hear any distortion/noise with my Deqx HDP-4 . It is extremely transparent. That was my major concern before listening to it.

What Deqx unit have you used, as the older generation I believe is less transparent.


BTW, DallasJustice now uses Deqx.

DEQX --is your system up to par? - Page 3
