| Revel Salon 2 with Pass Labs amps You never mentioned your room size, but if it's on the large side, say in the range of 400 sq-ft, 4000 cu-ft or larger, the Salon is going to work better than the Studio. In my auditions I always liked the Salon 2 better, and the difference was mo... | |
| Dismantle B&W 802D I can say that buying special speaker cables is a waste of money because its just good old cable inside with spade connectors.Special speaker cables are a waste of money anyway, but you have now uncovered what knowledgeable techie knows - that the... | |
| Upgrading woofers in a/d/s L2030, need help Do you realize how old this thread is? | |
| The truth on low efficiency speakers like B&W? 09-11-12: ElizabethYes heavy bass played loud taxes amplifier power.The "45 watt tube amps" are being used to play normal music at normal volumes. period.The 600 watt amps are for dudes with small dicks...As compensation. (i guess)The Parsound see... | |
| Thoughts on Subwoofer set-up? If you run your mains full-range, and assuming they have bass response to at least 30Hz, they may very well improve bass smoothness in your room. The more bass sources you have the more room modes are generated (dips and peaks in the perceived out... | |
| Software Flaw In New Velodyne Subs? Yes, I did call you silly. I think using a sub for less than an octave is very likely not using it to best advantage. Have you measured your room's bass response at your listening position? | |
| Software Flaw In New Velodyne Subs? No, Fplanner2010, you're misread my post.The 15Hz filter under discussion was not, as you say, the "low-cross" point. I was discussing the 15Hz high-pass filter that Velodyne makes mandatory in the DD+ line. Below 15Hz you get a roll-off whether y... | |
| Software Flaw In New Velodyne Subs? The software does not limit the response to 40Hz. There is a high-pass filter at 15Hz to protect the driver, but that doesn't limit bass in any meaningful way.Let me explain a bit. What a low-pass filter does is reduce the output of the sub *above... | |
| Help finding a Sub w/ quick punch down to 20hz If you want real 20Hz response at low distortion you're going to need a fair-sized sub. Your room size in total volume is a big factor. To have a worthwhile discussion we'd need to know that, along with your budget. For example, the larger JL Audi... | |
| Does a Sub for Wilson Sophia II make sense? That probably means you have some real bass problems. It might help if you get a better measurement system, like the Dayton Audio OmniMic from Parts Express. You need at least one sub, you might need two but I'd buy one first, and it looks like a ... | |
| Does a Sub for Wilson Sophia II make sense? What sort of source were you measuring? Pink noise? White noise? Warble tones?It looks to me like your entire bass range from 200Hz downward has problems, and low-bass is out to lunch. | |
| Does a Sub for Wilson Sophia II make sense? Because of room modes causing peaks and dips in any speaker's low frequency response, increasing the number of bass sources smooths out the in-room frequency response. Your speakers can be flat to 20Hz, but if you can't position them for minimizin... | |
| Callibrating Velodyne DD+ Subs in Stereo AutoEQ only works for daisy-chained subs. However, for the purposes of set-up you can daisy-chain them, run AutoEQ, and then connect them in stereo if you desire.I should mention that I'm very unimpressed with AutoEQ. It does not produce anything ... | |
| Best Amp for Revel Ultima Salon 2's? It is very unlikely that different amps will sound significantly better than the XPA-1s. Tubes won't sound much different, at least they shouldn't, unless they are poorly designed (like having a high and uneven output impedance), defective, or sim... | |
| frequency range for instrument vs speaker I have spectral analysis software on my laptop (the OmniMic from Parts Express), and a surprising number of recording show sub-30Hz energy, especially Telarc CDs. If you're into contemporary jazz I think the 20-40Hz octave is critical for really h... |
