    RBH signature review part 1

    Freeflap; Some comments for you: Great review. Thanks for your attention to detail. I love the excuse of inwalls costing more money :) Do NOT disable the 12" woofers of the 1266's. The top end of the speaker is crossed over above 100Hz. The side woofer is essential. It sounds to me...

    Roger Russell's new loudspeakers

    I am very skeptical about this design as well. Boosting driver response to compensate for design inefficiencies is not a good thing to do IMO. I also never heard a mid woofer that can play highs as well as a dedicated dome tweeter. I won't even touch the bass issue with these 3" drivers :D...

    Which is better? 1 sub or 2 subs?

    2 subs are ALWAYS better than one sub, especially in small rooms. It's not about the added SPL as much as it is about superior modal control to achieve smoother bass response in a wider listening area. If budget is a concern go with the lower model and get 2 instead of one higher model unit...

    THE ALL CHANNELS DRIVEN FALLACY

    I read parts of the article and I am confused. How does an amplifiers specification on WPC relate back to the actual load on the 120VAC branch circuit. Yes your calculations are correct though you can expect between 45% to 50% efficiency figures at max power. Amps and power supplies get...

    THE ALL CHANNELS DRIVEN FALLACY

    Why do you need to run an amp at 1 ohm? There should be little reason for a loudspeakers impedance to dip much below 3 ohms if the crossover is properly designed. 15A is on the primary 120V side. You can of course achieve higher current on the secondary side once the transformer steps the...

    THE ALL CHANNELS DRIVEN FALLACY

    Dan here is the response to your question directly from Mike from APC The PF strongly depends on a number of factors including the Diode Conduction Angle. The PF and Diode Conduction Angle are affected by: AC Voltage Waveshape (Voltage on the Primary) Governed by: Impedance of the...

    10 Biggest Mistakes in Loudspeaker Shopping

    Be very careful when you confront these guys. I had a couple of them confront me on their speakers and I respectfully said I wasnt interested. They persisted and I finally told them I am in the industry and I know all about Street speakers. One man said, "What our stuff isn't good enough for...

    Speaker Break In: Fact or Fiction?

    Ok let's get back to the topic of speaker break in and put the cable snake oil debacle on hold for now. I just pinged a reliable industry source who does some of the most definitive research in loudspeakers on this very topic and here is what they had to say: So it appears to me that if you...

    Speaker Break In: Fact or Fiction?

    Measured data on what, speaker cable break in? Hmm since I have over 100k worth of test gear to measure cables, along with a fairly decent EE background with a BSEE, I think I have a basic understanding of electrical theory and it applies to cables. Perhaps you should do a little reading...

    Speaker Break In: Fact or Fiction?

    Danny; It's kinda hard to take anything you say seriously when you promote speaker cable break in. If one can't even get the basics of wire correctly, then everything else is left to chance. :rolleyes: http://www.gr-research.com/components/wire.htm

    Powercords

    The only way a power cord can make an audible difference is if it is connected to a poorly designed esoteric amplifier. Filtering should be done in the amp's power supply or with a power conditioner, NOT a cable. It's like trying to place a band aid on an open wound instead of stitching it...

    Those are awesome $0.75 tweeters :D I love the stamped metal basket woofers too. If these speakers sold for $125/pair they would be a great value. I am not sure why they have an electrolytic cap in parallel with one of the tweeters. I have to see the rest of the crossover to know whats...
