Room Correction Systems and Electrostatics?
I can't answer your question directly, but from my experience with my Quads (2805) and 3 different rooms, placement is extremely important for smoothing out the bass. You might try moving them out further from the front wall about 6 inches at a time and listening to see if the bass has improved. Dave |
I have ML Summits, and my room adds some nasty bass nodes. I happen to have a Denon 3808 (for HT use) and tried the Audyssey MultEQ XT with my Summits. To my ears, it did an admirable job in taming the bass, with little loss of musicality. Ultimately, I plan to add some bass traps and acoustic panels, and hopefully won't need to employ EQ. I suspect Tact, Lyngdorf, or DEQX would likewise work for your Quads, but optimizing acoustic treatments first is what I would suggest. |
Yes. I used, among others at different times, Soundlabs and PK restored stacked 57 Quads, driven by SS and tubes at different times. A Tact 2.2 XP helped tremendously. REmember, too, that the TacT, Lyndorf types correct for phase and arrival times, too. With phase correct speakers (single drivers included), you'll almost certainly be well pleased , more likely, amazed at the level of articulation and tonal balance. I don't argue with the religious zeal of the analogue fan, I have nice analog and if I could avoid the DAC issue, I'd love to, but that's a necessary evil with TacT/lyndorf. With that, I have an uneasy truce. Rives, anyone? However, in my system, in my room, I wouldn't even want to hear it without High quality EQ. I know what music sounds like and have over $90k in a sytem. Trust me, without EQ, my room sounds terrible. Some of us don't have rooms that will work with us, dimensionally or otherwise, and that CANNOt be corrected with traps, panels, etc. Electronic treatments are just necessary at that point. Maybe I'lll have a better room one day (my equipment is just fine, thanks), but for now, I swear by room EQ. It doesn't matter if it's di-polar or not (I'm using Lowther single drivers now and it still sounds pretty good). |
As has been stated--no EQ is the best EQ if you can get away with it. However, problems in the bass sometimes require large, heavy and expensive devices to deal with the bass problems. Sometimes, there is no passive solution for the bass at any expense given a room's size and dimension. If that is the case, the Rives Audio PARC is the best solution as it has no A/D or D/A conversion. It works only in the low frequency and is designed with 118 db signal to noise to have the least possible effect on the overall signal. Buy Carl's PARC--he takes great care of his equipment. And if he already sold it--well, we will sell you one. |
As a SoundLabs A1 owner for over 3 years now, I too struggled with huge bass peaks in my room. I had 3: one at 14db around 30hz, and two others at around 6-7db at 100hz and 250hz. I just wanted to try out the PARC even though two audio friends (who I greatly respect) told me this was the WRONG way to solve the problem. Well, I tried it anyway. The PARC did an outstanding job of flattening out the peaks. The clarity of the midrange was truly outstanding. However, with the PARC in the line stage to amp link, I had to pay big $$ for another IC without seriously destroying the 3D my system had. And the same was true with the power cable. The stock power cable here should NEVER be used! So if a PARC is one's only choice, plan on some serious expense for the cabling or you will significantly lose much from what your system had before the bass peaks issue came into the picture. With all this said, removing the PARC was ultimately the way to go. It was clear how much the PARC was clipping dynamic contrasts. This alone made me do all I could to resolve the bass peaks in other ways. Just bringing the speakers out another few feet into the room significantly reduced the bass peaks; the PARC would never again be used in my system. Without the PARC and the bass peaks down (not fully removed), I had the ability to play a little with the SoundLab bass attenuator....not ideal but now I had a more pure signal path and the dynamics and body of instruments made this very clear. For a movie-based system, the PARC would be an acceptable option for me. But for a high resolution music-based system where ambiance, decays, dynamic contrasts, low-level detail, etc., the things we pay dearly for, well, it's not atop my options list. It depends on how well the peaks can be tamed by other means and not destroy other aspects of the signal. With the cost of the PARC and the needed cabling, I am sure there are ways to treat the room or position the speakers for much less cost for all but the few rooms/systems where there is no other option. And for those, I would be on a quest to find a speaker that was more suitable for that room rather than to try to "fix" the system with an active "corrective" device. |
