DEQX Mate

Not familiar with that one, I have Fuzz Measure. I have a friend, an RPG employee... (local to me) they have their own software too Room Optimizer?

If there was an easy no/low pain option, you would have found it. Mad Floyd probably had the most pain free way of doing it through JRiver on the front end. My fear for you is all of these other options, DSP speaker, DEQX, Rives Parc.... will be heard up the frequency range. You may decide after its all said and done that you'll just live with it as is.
 
You're probably right or move!

DSPeaker 2.0 I think only tackles 150hz down. Thoughts?

Still no comment regarding DEQX. That's ok, I'll continue to investigate. Other than this annoying 72-78hz issue, my room is sounding better than ever. Of course, being the OCD audiophile I am, I'm determined to fix this last remaining node. Like Bill Murray in Caddyshack, I will get the little bugger!

Hi Mike

The Rives Parc is a waste of time and money as it effects transparency a lot.

The Deqx HDP-4 works wonders on my "problem" areas between 50 and 200hz and is transparent. That is all I use it for.

Your 72 - 78hz will be a cinch.

I would bet you would end up having 4 profiles to suit different types of music. :D

cheers

Thanks. I would likely do the DEQX that allows you to use your own preamp. That being said, do I still need to use the volume control of the DEQX? I kind of remember something about that.

I think you need a tape loop to use your own volume control on the pre amp. Or maybe keep the Deqx volume control at a high enough level to stop bit stripping and use your pre amp volume? having the deqx window open on your laptop would make that quite easy.

Both my pre amps have tape loops, so not something I have looked at in too much detail.

I'm still considering the possibility of adding a couple of subs. Does anyone have any experience with this product:

Nyal and I added a pair of mono JL F113 subs using a DEQX HDP-4. One sub on frontwall and the other on the back wall. The objective is to eliminate remaining front/backwall modes/nulls and also gain greater dynamics. Mission accomplished! The only issue in this configuration using the DEQX is that you can not have a second mono sub out. So both subs must go out same channel. In my case, the back sub needed to be delayed slightly more than main R/L. So we used the controls on the rear sub. Nyal is very good with REW so the phase response at the crossover was seemless. However, I am going to use a minidsp box to delay the rear sub a little more precisely so we can totally eliminate slight ringing a 23hz. I'm greedy. :-).


Bass is spectacular with the two subs. They are integrated so well, it would be impossible to know they were there unless you saw them. Most sub integrations don't use proper delay to make everything cohere in the time domain. With the DEQX and Nyal's expert setup, the subs blend perfectly. It's a no downside kind of upgrade. It's also a BIG upgrade; not like a cable or even typical DAC updrade. It's like having a total system refresh.

I have very accurate speakers. We measured them with my earthworks m23. We were amazed how well matched the left and right speakers are at 1m on axis. However, Nyal came up with a very gentle FIR filter between 1khz and 14khz. The filter is totally transparent. It makes a nice improvement. My point is that no matter how good the speaker is thought to be, there's always significant improvement to be made with careful and expertly applied DSP in the DEQX.

I bought an HDP-4. Its a mega improvement and represents a shocking value compared to all other gear I've owned.

Thanks. I dragged over my massive home theater SEATON Submersive subs tonight. I didn't have a way to cross them over and I have no DSP, but for giggles, I want to give it a try. They ran full range which is 9hz - 200hz. These are dual canceling subs. So essentially, it's like having four subs.

They didn't make things better in the 73-78hz range, but they didn't make things worse.

DSP with sub integration. appears to be my only option.

Mike,
Nice room! It looks dark in there. I like my room dark too.

I really don't think it's possible to integrate subs without delaying the main R/L channels. Of course, you could try to time align the sub by putting the sub in the middle of the room closer to you than the speakers. But then you wouldn't be able to use multi-subs to destroys modes and nulls to get smoothest response.
 
Mike,

I've been too busy dealing with my own mid bass hump to read this thread earlier. I think I reduced mine significantly by changing speaker and listening position. I'll take some measurements to confirm over the weekend. But my speakers are 4.5' from the front wall and I'm 15' from the speakers. I don't think this is typical Wilson setup, but to my ears, worked the best.


Dallas, Nayal will be helping he with my room as well.;)

Thanks. I'm leaning that way.

Allen - it's my room I'm afraid. I've put the wheels back on the Alexia's and I've moved them and my seating position all around.

I have worked with Nyal several times over the last 2 years. If I had REALLY listened to him, I would saved me a tremendous amount of money. It's funny because every time I buy something from Nyal, I can sell old stuff for far more money than the new purchase and I always get much better music.

The only subs I am aware of that will do what you are trying to accomplish are the ones from Vandersteen. You might want to call and talk to Richard and get his advise if you think you need a sub presence. His approach is unique and uses only 8" drivers for speed. I just received a pair of Treo's on Friday and while according to JA they go down to 29hz, something was missing. Tonight I put the two Vandersteen subs back in high passed at 60hz and the "magic" came back. You don't hear the subs, but you know they are there if that makes sense. You could always try a pair and if it doesn't work move them on. The closest dealer to us in Florida is Alan Jones at Audio Alternative in North Atlanta. I have owned a few subs in my day. Sealed, ported, transmission line and the only ones that worked for me with at least a dozen speakers were the Vandersteens. Just my humble opinion.
