  1. Yes, I dropped the taps on the T2A, so the response curve is flatter (reduced the rising response by 3 dB).  The result is the woofer at 94 dB/w/m, squawker at 95 dB and the tweeter at 96dB.  My center floats in the air above the TV without much wall reinforcement, so I like the subdued squawker and tweeter better.

  2. The tweeter should be 7.5, the squawker should be 12 - 12.5 and the woofer should be 6-ish, unless a K-22-EF and it will be 8.3-ish. 


    I had a K-77 tweeter with loose terminals that didn't always contact the voicecoil leads.  Manipulating the tweeter often gave good DCRs, until I noticed the terminal moved.

  3. I did that to my center channel Heresy so it matches my Type AA La Scalas as much as practical.  The Type AA filter EQs the driver a little, but the Type E network compensates for the K-77s response hump well enough and the auto former protects it well enough, too.  You may not notice much difference.

    I’ve got a little G48 which is a nice sized carry piece but it feels like a cheap toy compared to the Beretta M9 I bought from Marvel when he brought the LS up to NC.


    As you'd expect, a Beretta is a nice piece of kit!  Blocks have their place, though.  😄

    It was a compromise between blown tweeters and sound quality. It’s a known fact the tweeters were (are) delicate. Perhaps the threshold could have been a bit higher so the distortion would not begin until a higher wattage. 

    Newer technology performs better such as poly switches, but they are not the final answer. 

    I personally prefer the right light bulb. 



    The K-77-M is substantially more durable with a 10w cont. rating.  In a home setting they are not at much risk so you can defeat the KLiP diodes.  I would not recommend that for Pro Audio. 

  6. Nice find!  If you keep them, you'll want them on the floor and just a few inches off the wall or corner to get better bass from them.  You can expect them to need several days for the woofers to loosten up and make full bass output.  Ultimately, you may want a subwoofer, too.  Many of us do.

  7. I have one and I don't know how you'd do it.  My phones, etc, won't pair to 2 devices at once and have no provision to separate channels.  It does have an aux input, so you might be able to make cables to send each channel to different Grooves.

  8. There were probably more raw birch Heresy Is made that any other.  Since the "finished" H Is are also made from plywood, there should be no difference in sound. 


    MDF cabinets may not be as strong as plywood, but are strong enough and non-resonant.  Better to buy the sound you like in the condition you want and ignore the material.

    It does look nice AND can double as a spot.....to keep your Glock....





    I just acquired one of those rotten things. It uses the same mags as a carbine I have.  Kind of a New West sort of thing. Despise the trigger.  🙂

  10. Gil and I exchanged e-mails, yesterday.  He said to say "Hello!" to all of you. 


    He is in a new facility in Chicago and finally getting PT.  He is able to do some walking with a walker and is getting more use out of his left hand.  He says it is slow progress, but I think it's grand!  His old phone quit working and BIL Joe has shipped him a new one, due this week.  Maybe he is a little harder on phones than some of us.  😉 


    I was getting concerned since he had been unreachable, but I think, now, that he's OK and getting what he needs.

  11. The K-700 makes for a nice sized lamp, nearly the same height as the ginger jar lamp that donated it's organs.  It is now on my nightstand and the extra area of the base is usable for some of the stuff I usually keep there.  A K-400, ..... hmmm?
