    Are the new B&W 800 Series D3 Diamond Loudspeakers Their Best Effort Yet?

    It looks like B&W really worked on fixing resonances (something Dr. Floyd Toole talked about in his book on the old 800 series). The cabinets seem far more rigid and especially NOT using Kevlar cone material any more is a BIG improvement in my book. I'm curious to hear the 805s in a small room...

    Bridged vs Not Bridged Mode - amps / wattage question

    Be careful and make sure the amp is designed to be bridgeable. IN bridged mode, each section of the amp will see 1/2 the load impedance. So the 8 ohm speaker in single amp mode now looks like a 4 ohm load to each amp half in bridged mode. Some amps aren't rated for 4 ohm loads in bridged mode...

    How to Treat Small Room Acoustics

    I think you can certainly do some improvements with manual PEQ for your situation. However you will need to pull some measurements at your seating location to see where the problems are. Definitely don't add more passive treatments if you feel your room is already too dead. My theater room...

    How to Treat Small Room Acoustics

    Floyd; We have a similar situation. No right wall in my room and absorption and thick drapes on my left wall. Perhaps you can address a question in my mind. When you have absorption stretched over fabric, does that NOT make the absorption panel a poor off-axis absorber? In other words, it's...

    Are the new B&W 800 Series D3 Diamond Loudspeakers Their Best Effort Yet?

    It’s not every day that Bowers and Wilkins hosts an exclusive event for a new product announcement. It’s rarer still that the venue for such an event will be a legendary recording studio. But that’s exactly what the venerable British speaker maker did to announce their updated flagship line...

    Sonus Faber Tower Speaker Comparison: Do they live up to the marketing?

    Agreed and we never said they didn't make good speakers. However it's fun to pick apart marketing from companies every now and then. We do this all the time for cables so why not speakers too?

    How to Treat Small Room Acoustics

    Ideally yes but it's always better to eliminate loudspeaker resonances (even at low F) anechoically so you can separate the room influence from what's actually happening in the speaker.

    How to Treat Small Room Acoustics

    For a long time, conventional wisdom has treated large and small room acoustics as one in the same. But there are fundamental differences and objectives between the two and thus they should be handled differently accordingly. Small rooms are dominated by room modes at low frequencies which...

    SVS ultra system vs. Def Tech studio monitors

    Adatrao; Welcome to the Audioholics forum! Sorry to hear of your troubles finding speakers in your location. It's tragic that you would have to pay above retail to get products to you. The brands/models you mentioned are all solid performers. You did your homework. However, I would go...

    Furman Elite-15 DMi and Elite-20 PFi Power Conditioners Review

    Some power conditioners use isolation transformers to help isolate from ground loops. They are usually a 1:1 ratio so they don't change the voltage at all. A good power amp should have all the filtration it needs both on the primary and after the rectification stage but I suppose more...

    Furman Elite-15 DMi and Elite-20 PFi Power Conditioners Review

    Some power conditioners that are transformer isolated are rated at less power than big power amps. The Furman is NOT a transformer isolated power conditioner so it shouldn't be a problem. The other reason is some amps have very large inrush currents due to the large capacitor banks. This...

    Yamaha Aventage CX-A5100 Pre/Pro vs RX-A3050 Atmos/DTS:X Receiver

    Or not do an EQ correction at all above the room transition frequency. ALL auto-EQ systems are dicey when trying to correct above bass frequencies since an omnidirectional mic does NOT approximate our hearing. I'd personally take a manual PEQ that goes down to 20Hz or lower for all channels...
