Asked them where the list is that they invented for an 'annoying website' and who made the rules. I was then transferred to a supervisor. I got an email about an hour ago saying the 'annoyance factor' has been removed. Are you still getting that warning? If so, maybe it will go away soon. I don't mind them telling me I'm annoying, but not the DIY site! :D

    There seems to be a decent number of complaints this month from other companies about the same thing.


    I would imagine if that happened to a bigger website like PE, or any bigger company, they could claim some serious lost sales due to that. Their home page is no different than their store front. Someone can't block the front entrance at Walgreens screaming that you shouldn't enter because their agency says it will harm you. My guess is they will get slapped with a lawsuit the next day.
    Norton Safe Search now says the site is safe. No more flags.

    No clue what to do about it if Norton's says it's clean, but can't tell me what is so annoying. Seems like a class action lawsuit just waiting to happen.
    It's obviously the Intrusive 1899.

    Yeah, I surmised that after I posted and read further down the thread.

    Another approach to consider is to use a high sensitivity pro mid. I use the Eminence Beta 8a pro mid in the project below, though it was open baffle mid and tweeter, not quite what you are looking for. however, the Beta 8a would certainly work well withing the range you are thinking.

    I did another open baffle mid project that used the smaller, 6-1/2" pro mid, the B&C 6md38. It should be able to handle that range as well.

    Just the name says it all.... "Maximus 12." I've had my eye on a set of those puppies since the first time I become aware of the design. I too like to think (emphasis on think) I live in the high SPL/Efficiency school of speaker design.

    One question though, what do they really sound like? Warm, harsh at the top? I've never had the pleasure of actually hearing any in real life. The giant midrange concept has come to me before also. Thanks in advance, all the best, Mike

    The 22TFF works with the SEOS 8, the 27 may work as well.

    I like Norton now-days. It seems to be pretty fast and very good at what it does. I get the newest version of its full Internet Security at a very good price through my employer. My wife likes the "Safe Search" extension for Firefox and that's what flagged the diysoundgroup site. It doesn't show any virus or malware, but it has an "annoyance rating", which seems odd. I told Norton to click on through to it.

    I think it will be possible to cross the SF woofer somewhere between 1.5 kHz and 2 kHz. The challenge with crossing an 8" to a tweeter in that range is that the woofer's off axis response is dropping off pretty quickly by then, but the tweeter's will be strong. You might consider using the RS28 tweeter along with the Denovo SEOS 8 waveguide that is made to go with it. That will help match the off axis response of the two drivers at your crossover point. The RS28 has also been crossed as low as 1 kHz, which would be a nice option to have if you have trouble getting the Silver Flute woofer to sound good up to 2 kHz.
