Shouldn't make any difference. What does Def Tech say it should be? It is probably set up to place a very small load on the amp through those inputs, so you should have it set for what your main speaker loads are.

There are only about three theater systems in the U.S. They consist of JBL, Klipsh and E.V. I think those are the main ones, there could be others. They are all good systems, but like any system, if the person running them doesn't know what he/she is doing, it won't be very enjoyable. BTW, if my kids talked the way you do here (do you do this all the time?) you wouldn't be sitting down in comfort for quite a while. Since they are now all past their teen years, I'm glad to say they still don't use language like that. It is really required to live in a civil world. The quicker you catch on to that, the better off you will be.

I'm with Colin and Craig both on this one. Since I only paid $50 for my original ST-70, and then had it for close to 30 years, the money invested in the upgrades I did were well worth it. Both versions sounded great to me. I like the new version better, as I don't have to find the 7199s. There are better quality frontend boards than what I built, but it is still a solid sounding amp. Very pleasant to listen to and use.

We have a pair of each in the house -- originals and HII. The HII sound a bit smoother to us, but not necessarily lacking. Bruce

Depending on the D.C. voltage required, you need a voltqge regulator and filter caps to smooth out the D.C. ripple on the line. For low current, like the phantom power, it wouldn't be too hard.

You could do this on the Jubilee style, where the horn goes horizontal. It would be like looing at the back of a LaScala. The corner horn I plan on building is done this way, and I am contemplating putting a JBL 2405 there. It is a ring radiator with a slot type of horn, with the cutout a circle. Has a little bit better repsonse than the baby cheeks 2404 as well. Unfortunately, the price is about the same.

Two Newfoundlanders went on a camping trip. After a good meal and a bottle of wine they lay down in their tent for the night and went to sleep. Some hours later, Lloyd awoke and nudged his faithful friend awake. "Bryce, look up at the sky and tell me what you see." Bryce replied, "I see millions and millions of stars." "What does that tell you?" Lloyd questioned. Bryce pondered for a minute: "Astronomically, it tells me that there are millions of galaxies and potentially billions of planets. Astrologically,I observe Saturn is in Leo. Logically, I deduce that the time is approximately a quarter past three. Theologically, I can see that God is all-powerful and that we are small and insignificant. Meteorologically, I suspect that we will have a beautiful day tomorrow". "Is that all?" Lloyd asked. "Yes." Bryce replied. "Why, am I missing something?" Lloyd was quiet for a moment, then spoke softly: "Bryce, you idiot! Someone stole the tent!"

agghhh! Isobarik isn't what I meant. I'll have to look it up. I won't even try to explain it. DrWho, Sorry I didn't catch the 1/4 wavelength bit in your long post. My apologies. The woofers definitely need to be in a vertical array though, as you pointed out. Nite nite. Time for me to get some sleep. Bruce

oscarsear is correct. Melanoma is deadly and you may have had ONE sunburn when you were little and twenty/thirty years later it shows up. Another candidate is turning out to be folks who work in clean rooms. They think that may be related to degreaser/chemicals used. Same thing, where it shows up later, but the numbers are suspiciously pointing to some connection there. Cure rates are pretty low if you don't catch it in time, unlike other cancers that respond well to treatments. If you can't see your scalp, have your barber or whoever cuts your hair check for you. Of course, your spouse or significant other could also check. Bruce

Just wanted to let everyone know that my wife had surgery last Wednesday (July 6), to remove a small melanoma from her lower back. They also removed two lymph nodes. Got the path report back yesterday, and she is all clear. This means no other surgery or other treatment (chemo, drugs, radiation). She is up and about, and will be driving to town tomorrow on errands. She is healing up quite nicely. Many thanks for the prayers and good thoughts. I hadn't wanted to post again until we had some news. Bruce

It doesn't have to have much effect on the compliance. Being able to vary it just a tiny bit would give you some tuning room. What might work better would be an inductor with an adjustable iron core. We don't need to get testy! Dana - my pc is shut down while we are having repair made to the house. I'll send an email as soon as I can. I still want to build one of those models I have plans for. Bruce

The distance between the two woofers at the frequencies they operate in will not cause appreciable comb filtering either. You will have better horizintal imaging with the woofers and horns in a vertical alignment. Vertical imaging will be a bit narrower. There are some formulas on how far apart the 15 inch drivers can be based on the wavelength of the highest freq. they will reproduce, but I can't locate them at the moment. It was some information I cam across on the JBL site.

This is awful, since it is making a lot of sense to me. I'll repeat and try to make clearer: No connection between Driver A and Driver B other than them being in the same box. A vibrates and makes B vibrate, generating voltage that is dropped across the resistor. Depending on the resistor, Driver B is stiffer, etc If you have a load across the VC of driver B, the counter emf will cause B to not vibrate as easily as 'no' load across the VC. As Neil said, it is like the load on a generator makes it harder to operate. In that sense, it would make driver B stiffer. Perhaps an iron core inductor would work better than a resistor, but you couldn't adjust it as easily. This would be something we should be able to test pretty easily. A speaker can work as a microphone, which generates a voltage swing. If there is counter emf from that, it would then influence how the speaker is moving. If this were in a box, changing how that speaker moves would change the tuning on the box. Clear as mud, right? Bruce

My question concerns the ability to use an active radiator as a passive radiator and tune it by varying the load across its voice coil. ---------------- I see what you're thinking, adjust the output of the active driver to control the output of the active driver to subsequently control the passive. A resistor across the active VC is not going to alter frequency (hence no tuning), only overall loudness (limits current), but seems a waste of energy and is at cross-purposes, IMO. The passive would be tuned by the overall enclosure volume to a degree. Also a tuned cavity could be put behind and coupled to the passive to tune the resonance. But aside from that, it seems to me that the passive is intimately coupled to the active driver by the shared air space in the back chamber, and the resonance of that is determined by overall volume and the active driver's parameters. DM ---------------- D-Man -- Let's try to be clearer with this: Driver A connects to the amp. Driver B is a speaker with a VC as well, but connected to a variable resistance. Driver B acts like a passive radiator, the compliance (and therefore, tuning) of which can be adjusted by varying the resistance across the VC. More resistance would put a greater load on the EMF generated by the VC, causing a stiffer compliance. Is this what we are talking about? No connection between Driver A and Driver B other than them being in the same box. A vibrates and makes B vibrate, generating voltage that is dropped across the resistor. Depending on the resistor, Driver B is stiffer, etc. Bruce

Wheelman, Check out the cheap grinders at the bottom of the page on this link: http://www.wholelattelove.com/grinder.cfm Like the $20 range. We basically make a drip coffee, so eyeballing the gind is okay with us. You recoup your investment quickly. They have directions with them. Grind a pot worth (15 seconds or so) and pour the water. Bliss! You can also spend a fortune, but we have had the same grinder for years, and it gets used every day. I think ours came free with a coffee subscription from Community Coffee. Bruce

Hi Timshe, Nikola Tesla might be able to help you out. Seriously, if you don't want to run wire to the remote location, there aren't many options. You could broadcast to another receiver, from the Denon you already have. That would involve a small transmitter on the Denon, so send the signal to the other room where another receiver would pick up the signal and amplify it. The quality, without spending lots of money, would be marginal. Might be okay, but you still need the other equipment. Wire is cheaper. Are you renting and can't make holes? If these are on the same floor, can you go under the house with the speaker wire? Of course, this means holes in the floor. OR, if the walls are regular wood studs with drywall, you could cut in a box (like outlets go in) and drill a hole as vertically as possible through the bottom plate to get under the house. Then the wire could be run that way. Requires a long drill bit, but it would still be cheaper and sound better. Bruce

For those who brew their own coffee (or tea for that matter), you should try spring water, or at the least, water without chlorine. It makes it a whole lot better.

Jan, Welcome to the forum. Erik's plans are good, although not exact. He does have all the measurements for metric instead of English units. There are some plans floating around. I assume you have email. How large can attachments be to get through your system? Bruce

Our little town of Chattanooga doesn't have that high falootin' stuff! A small coffee roaster here in town has many varieties, but the one I get from him is Ethiopian Yirgacheffe. It be slammin'! We buy free trade/shade grown coffee to grind at home, and the brands change over time. But the all important thing, as has been mentioned, is to grind it fresh for each pot. Quite some time ago, our cheap coffee maker quit, so we started using our old Melitta coffee maker. We heat water on the stove and pour it through. I also give another vote for Community Coffee. My wife grew up in Baton Rouge, and walked past the Saurage house on her way to school. Bruce

This WOULD be what you want! And they are so simple, too.

I always hated going into American TV stores. The salesmen were like vultures, and all competed with one another.
