  1. Anybody from Florida driving up? I might be able to get a press pass for a free room, but would like to car pool...
  2. Seriously, you need a plastic wrap for moisture protection and at least three inches of foam on all sides. That should survive a six-foot drop. You can get five packs of rigid foam (Styrofoam) insulating sheathing panels at Home Depot and Lowes. Messy to cut. Overlap each corner. Pack snugly so item inside does not move.
  3. his is on the high side for vintage ss receiver that has not been refurbished, the largest model, the 930 sold for $150 on eBay before the depression, yet the sound of this receivers is as good as some of the best $2K receivers I have heard on big ole horns! Not tube like, of course, but still smooth and accurate without the SS harshness... http://stereolist.com/stereolisting/twin-powered-stereo-receiver/ very good with big ole horns! search the Forum, you will see how much people love this for the money (offer $50) or see eBay...
  4. Actually, I really dont like what Carver amsp do with big ole horns!
  5. CA Khorns for $2K on Stereolist: http://www.facebook.com/pages/manage/?act=75484578#!/pages/Big-Ole-Horns/142663002431283
  6. The super-high efficiency and ultra low distortion of direct connectivity horns is perfect for the sweet treble, imaging, soft clipping and second-order harmonic distortion of tube amps. Almost any good condition tube amp is going to sound great with Khorns! In all but the most demanding situations, even flea-powered tubes will be wonderful. Those situations include: extra large rooms, very loud hard rock, very deep action movies and bass lovers who live for double-bass riffs as strong as Colombian coffee. All of the suggestions above are good ones. None of them will give you tepid “background dinner music." All of them will provide the intoxicating grab of music. Unless they are refurbished, vintage tubes will give you irritating humm's, crackles, pops, buzzes, flashes and funny smells. Remember, one-third of the total power of a 75-piece orchestra comes from the bass drum. (That is why the incidence of hearing loss in classical musicians has been estimated at 4-43%, while rock musicians is estimated at 13-30%.) For this reason, I too prefer PASSIVE bi-amping with Khorns. The woofer runs full-range. So I run a 60-watt, class A solid-state amp on the bass bin. I use a 6-watt, class A tube amps on the mid and high end horns. I also use a very deep and steep 24-dB crossover on a 1,500-watt (peak) sub-woofer. The effect is the best of both worlds.

  8. I like the idea of a netwrok aware back-up storage drive, about $100 for 1TB, with automatic back-ups, keep us posted and lets do another weekend some time soon
  9. Boy, the Packers beat both the Colts and the Pats! Who wants it the most?
  10. Jenny, asst org for Live Music Meetup here in Tampa is a DJ... http://www.meetup.com/livemusic-96/members/4419018/
  11. great list Islander! Need to order some of those...
  12. what is the deal? no cheerleaders! That is un-American! BTW, Steelers
  13. Here's how to enjoy your music while saving your ears Noise of 85 decibels or louder can damage the hairs of your cochlea, a snail-shaped structure in your ears. Your iPod at full volume can hit 105 decibels. Worse, hearing loss tends to occur over time, unnoticed: "If you keep introducing noise trauma to the ear, you can cause permanent damage," says Theresa Shaw, Au.D., a senior audiologist at New York University. So do this: 1. Turn it down "If the person next to you can hear what you're listening to on your iPod, it's too loud," Shaw says. One study showed that an iPod exceeds 85 decibels when it's set between 60 percent and 70 percent capacity.
  14. http://www.reuters.com/article/idUSTRE70N4VB20110124 Sunday's matchup, in which the Pittsburgh Steelers beat the New York Jets 24 to 19, earned an average household rating of 31.3. It peaked at a 33.1 from 9:00-9:30 p.m. EST.
  15. I’ve reviewed, even manually measured, a few loudspeakers over the years. Not sure I can find my post or article, so I will simply summarize what I remember. Depending on the room dimensions and modes, I found that the mid-bass response of almost all speakers sounds better when placed three to four feet away from front and side walls. Since creating mid-bass is usually the task of the front speakers in a multi-channel system, I would certainly place them away from the front and side corners. http://www.enjoythemusic.com/magazine/equipment/0408/loudspeaker_roundup.htm
  16. I love the idea of putting the desk behind the couch! I wanted to do this for many years. The optimal position for big ole horns in a rectangular shaped room however, is along the long wall. You will get a much wider soundstage. You will experience room modes that sucks out low, mid and upper bass. The room robs your system of energy. No amplifier or equalizer is powerful enough to fill these modes. http://www.realtraps.com/modecalc.htm
  17. With 11 by 22 square, with 8 foot ceilings, you will experience room modes that sucks out low, mid and upper bass. The room robs your system of energy. No amplifier or equalizer is powerful enough to fill these modes. http://www.realtraps.com/modecalc.htm Realtraps calculator shows that the worst mode above normal is at 51-Hz (mid-bass). If you notice that an isolated line is higher than usual, that means there are at least two modes at that same frequency. Next, go the Hunecke calculator. This mode calculator is not good for finding troublesome modes. It is hard to see what frequencies are trouble spots. Yet the Hunecke calc is excellent for graphically suggesting the best locations for placing acoustic room traps. Once you know where the modes are, click on the Show radio buttons for frequency closest to your worst mode. http://www.hunecke.de/en/calculators/room-eigenmodes.html It this case, the Hunecke suggests that placing deep bass acoustic traps on four walls might have the best effect for decreasing the effect of the 51-Hz mode. The next mode is at 102-Hz. The Hunecke image suggests placing three room traps at equidistant from each other on the long wall and at the mid-point of the short one. The floor and ceiling are the same as the long wall. Consider placing traps on the ceiling too. The best way to prevent sound from propagating up into bedrooms above is to isolate them from the noise center below. A concrete block ceiling would work. So would a double wall. You can also seal off the bedrooms with a special sound proofing materials like CertainTeed’s Thermafiber Sound Attenuation Fire Blankets covered by Acoustiblok sheeting. Fill the Thermafiber between the joists and beams. After the batt is in, simply staple or nail the Acoustiblok to the joists and beams. It wraps around pipes and fixtures. You can lay it over lighting fixtures, just be sure to tape any cracks and completely seal the ceiling. http://www.acoustiblok.com/theater.php
  18. Most soundproofing techniques don’t attenuate the low frequencies. Yet it is the deep bass that transmits and penetrates through walls. The highest STC rating ever achieved for sound deadening construction by the independent Architectural Testing laboratory is STC 85! This was accomplished by using two layers of 16-ounce, black Acoustiblok sound proofing sheeting, two layers of CertainTeed’s Thermafiber Sound Attenuation Fire Blankets and two layers of drywall, secured with two sets of steel studs on both sides of a concrete block wall. In other words, double layers of sound proofing enclosing the blocks inside. This configuration stops more than 99% of sound! It dramatically blocks low, middle and high frequencies. Sixteen ounce Acoustiblok is only 1/8” thick, the same width of two quarters. The next best wall configuration still blocks 99% of sound. Using just one layer of Acoustiblok, Thermafiber, drywall and steel studs on one side of a block wall accomplishes an incredibly high STC of 71. See http://www.acoustiblok.com/uses.php
  19. right, diffuse, not deaden not confused anymore

    anybody got TB??

  21. Insulation? NASA developed Thermablok aerogel insulation, the most powerful insulation on the planet, is the highest value material ever produced. It has the highest R-Value, unmatched physical and mechanical properties, will not age or be subject to mold, mildew or any environmental problems. Its hydrophobic, completely harmless, recyclable and environmentally safe.
  22. what is your frequency response in the room? that will tell you where your problems are check out: http://www.acoustiblok.com/indoor_sound_panels.php
