As mentioned above - the physics doesn't care about the number of ports as long as the escaping air adds little to no extraneous sounds. You will hear arguments otherwise, but my personal experience is that as long as you design to limit port noise there is no difference in sound. I prefer fewer ports because it usually makes it easier working with the baffle and provides a cleaner look IMO.

If there is no upscaling going on or if bad upscaling is going on you will have this type of problem when viewing some standard definition broadcasts. If you are using satelite for local channels you will invariably have this issue due to the heavy compression of the local channels. There is little to suggest from you message that it is actually the monitor. Do you have the capability to upscale anywhere in the chain? making the delivery to monitor as either 720p or 1080i should have some positive effect.

I think your lack of response is that folks are scratching their heads a bit. T/S is primarily useful to speaker box builders for cone speakers - these measurements help one know the effects of the cone movement in designing the appropriate box for the desired frequency range. The K77 is an integrated speaker (my term) - all of the speakerbox properties are built into the unit. Your issue becomes one of dispersement based on the horn flare (again my simple terms), placement on the baffle and rigidity (or lack therof) of the baffle. Others can address this much more accurately and elequently than I.

My first LOL of the new year.....

Congrats Erik - I remain a loyal fan of the old Ron and Tom show at SVS. They make wonderful price performance units (focus on the performance). Kelly- as others have said - with diligence a quality sub definitely can enhance your music - I hope you get to audition one that helps you get the itch. It turns out to be a 'fullness' to the sound that I can only think of as filling in those lower harmonics that exist in a live environment but not with most standard loudspeakers. If done correctly it will be invisible to your ear until you take it out of the mix.

I could be mistaken, but I believe ESN stands for Extreme Slope Network - the logic is thus - if you can filter for more dramatic db roll off near your crossover frequency (for each speaker) you have less competition on each side of the Xover frequency with disparate speakers trying to creat the same sound. In my experience it does create a very nice improvement, but it can be a bear to get right and is best done after you have measurements of your existing config. Dean or Al or Bob - please jump in here before my bad information gets overutilized (these folks can answer much better than I).

Ok - not on a Khorn , but Maron's advise was my rule of thumb. In my speakers they were about 2 db hot verses the mid horn - down 2 db and all was hunky dory...

Are those a specific JBL model or a custom system you built? Custom built - I believe the model most like them was a 4333a/b studio monitor. I, at one time, actually saw a better fit, but that will have to do. It is the same three way concept with some newer components. It is a 2225 15" in a separate bottom enclosure tuned to 40hz, the top section has a 2425 mated to a 2370 horn for the mid and a 2404 baby cheeks for the high freqs. I used a 3110 network for the low frequencey Xover and a 3105 for the HF Xover. I had to get reasonable good short to medium throw out of the lens. The woofs were reconed 2205s - and they are very nice (after the breakin) as well as the 2404. I very much like the sound - it is so very much like a cornwall with a very smooth bass and UHF. They are my favorite speakers (currently).

You are right, it is not high def. It sends a digital 480i signal (the best you will get on current DVD). I do not have the avi do any conversion, I let the media center for the Monitor up convert - I tried it both ways and the TV does a better job. I would prefer to have the HDMI connect for high def, but I guess our friends at Charter don't want the headache of trouble shooting everyones digital connections.

And here it is on the shelf above the TV

I went with the modification mentioned. Being just a bit handy will work - I used fostex woofers for my center. Here it is naked:

Milton10 wrote: I read somewhere that some televisions convert the HDMI digital signal back to analog as soon as it enters the set. I don't know if this caused the problem, but would suspect that it may. Has anyone else heard of this? I think it depends on your monitor/tuner. With my Pio PDHP5050 (plasma) the signal is pure digital from the HDMI connected Elite 59avi to the media reciever to the monitor. It is a cleaner picture than the component connected cable box (our Charter friends do not offer a DVI enabled Moxie box here). I do not know if there is a conversion on the component feeds or not. In my experience component is far, far better than S-Video and HDMI is slightly better than component (although I haven't done a test that is exclusive of the component attached for component vs. HDMI). All my sound is through coax or optical - I cannot discern any difference between the two. I modified my cabinet that used to house an RPTV for a plasma and a fireplace

Ditto on the Lansing heritage site. The folks there have been a tremedous help to me over time. Remember, just like here there are quite a few there that are completely convinced of their rightness and clearly let you know it. They were a great help when I built these JBL

Since we are talking Demming, I thought I would throw in my two cents. Most of the following is sole the opinion of the authur. Demming went to Japan to 'discover' their secrets of efficent, inexpensive quality production. He brought back his empirical analysis which eventually became 'Total Quality Management' - it became the darling of Harvard and kin and was the tactic being taught to a whole generation of new business leaders. Demming's only real business success was as a writer regarding quality assurance and his focus was an extension of Bell labs statistical work in the 1940s. It was clear from initial implementations that efficiency and expense goals could be met. What many American business discovered in this process was that their quality standards were being met - they were simply lower standards than the Japanese. Demming always held that the quality control issue was more cultural than practiced and that we needed to introduce habits that eventually created the culture. A few pieces of reality creep in - we do have more respect for the concept that quality is in the process. Unfortunately, many large businesses have adopted the concept of human resources being little different than any other resouce (an out come of a focus on the expense structure). We have lost sight of equally supporting each of the three primary business issues - the shareholder, the customer and the employee - we often seem to focus on the shareholder and the customer with too little time spent on the employee. However, we have become the most productive business force in the world. I guess you get the good with the bad. What we have is a plan put into play by a group of 'minders' - much of corporate CEOs are not entreprenural, they are simply 'minding' the shop. We reward them as if they are entreprenural and we have created a hugh workforce ambition to be come the 'minder'. That is something I do not find attractive, especially as I watch these 'minders' do some of the most outlandish things in the name of quality and profit. Sorry about the long message - this is something that I could spend lots of time discussing over a bottle of Jack Daniels. Any offers?.....

I'll give my 2 cents here. There is a school of thought that a speaker should produce quality sound an octave below and above auditory limits of the human ear (although that is a pesky thing to make the same for all folks). My experince has been that it is reasonable to do so and that there 'seems' to be some difference when folks do so. I try to design my listening rooms for just that and I am quite pleased. So if 40 hz is as low as a grooved piece of vinyl gets, then the 20 hz meets my octave rule (in this case an octave below the reasobaly produced lower limit).

If I read it right the whizzer on the Fostex is where they get the high freqs.

Congratulations for finding a sound that pleases you thirdeye. I have heard many such designs and I have heard rave reviews such as yours - I trust that you have found the sound you prefer. It is simply not for me - in all cases it just sounds a bit too shallow in the upper and lower freqs for my taste. But what the hey - I have very trusted friends that swear by Bose - go figure. The 'new' design you mention has been around for quite some time. Check out Pi Speakers for a similar homemade solution. The speakers must have some sort of filter to manage to the supertweeter - most likely a zobel (a great easy to do upper end filter solution) is in place. Other wise there would be a tremendous hump at the frequency where the woofs end and the tweets start.

FYI - from Craigs List http://stlouis.craigslist.org/ele/113340464.html I know nothing else, but I can assist anyone that wants to purchase if they are out of the area (pick up, audition, etc.)

Well done Bob - Donation sent. Thanks for taking the lead in this.

I agree with both Maron and Whell. My Maggies may have been the best sounding speakers I ever owned - however, due to the placement constraints of most rooms you end up with an extraordinarily small sweet spot (not to mention that most folks such as myself that are over 6 feet tall can get quite irritated when standing and having the sound change). It was way too much like having huge headphones. To repeat - they still have a great place in my heart when I was able to stay in that sweet spot. A music room with one chair would be just right and leave you smiling...

Now that is interesting and the more I noodle on it it makes sense - worth a try....

Thanks Doc - Pioneer has a seperate tuner/connection box called a media center for their Plasma displays. The box actually sits with my equipment (makes wiring very simple). I had considered some of your thoughts, but in my case I can't exhaust into anything other than room space. I may well learn to live with it - as you noted it is only during quiet stretches that it is noticed (actually - air handling in the room HVAC can create a higher floor noise, so I am being a bit picky). Indy - I have seen your pics and many, mucho kudos - looks great. I just finish replacing a broken rptv with a fireplace and a 50 inch plasma on top of a fireplace for my room - pics later...

Just for comparative - the Pioneer Elite 59avi is being replaced and can be had for a good price. It was my choice when higher priced, but there is so very little difference from the Denon that your choice gets very subjective.

Yo Doc - I would be interested in any reference on getting rid of fan noise. I have a problem with the media center for my Pioneer plasma and really don't want to try and change out until I find a quiet one. As to the 3802 - I have been a fan of mine for the last several years. I really don't get why it doesn't get rave reviews, but it will need to break before I remove it from my set up. I do like the Eagles DVD - it is very well done. I would also recommend the SACD of Dark Side of the Moon for another great mix. Cheers..

Now this was fun to read - although I still think my answer on page one was more germaine and precise to the original question. However - entertainment value has been high...
