Try Mike at AcousticSoundDesign. Of course the more you buy the better the deal. And welcome to the Forums. Search around a little, its not hard to find info about the Hope Gathering. Oh yea also I don't think Klipsch wants you showing up at the factory to buy 1 pair of RF7 IIs

Just got 2 of these drivers a week back. Waiting for Erich at DIYsound to come through with cabs. Took them out of their packing boxes last night to ohm out voice coils to make sure they're OK because it maybe a while before i get to building them. Anyway my first thoughts about these drivers are they sure are purdy. Its a shame they have to be put in a cabinet!

If a tapped horn is designed correctly, the wave coming from the horn and the sound produced by the driver are in perfect phase with each other. That's why it's critical to get driver placement as close to perfect as possible when building one. I know nothing about this subject but I'll go out on and a limb and ask, isn't this true only at 1 frequency?

A grateful and enormous Thank You to all who served and are serving to preserve our freedoms and way of life. God Bless you all. ^And Thank you Canada for being the best neighbor a sovereign nation could have.

My recollection is Roy showed the mod they use. Grounding the XLR ground pin to the chassis (if I recall correctly) Something about "The Dx was designed, presuming you'd have it rack mounted and the ground of this & that would flow through the rack to the rest of the system" (or something like that) So, they take each one they get and add a ground wire internally because the ground isn't always carried forward given how it's designed. If you don't have it rack mounted, then you have the same potential issue. That's my recollection of the issue. Here is a thread about Input Grounding Modification of the DX38 https://community.klipsch.com/index.php?/topic/109276-humbuzz-ev-dx38-xlr-rca-adapters/?hl=%2Bev+%2Bdx38+%2Bground+%2Bmod I prefer and recommend the Female XLR Plug option I described in the above thread because it is easily reversible and does not require opening up the unit for the ground modification. If someone is comfortable going inside the unit then a wire can be run from the case of the EV DX38 and Pin 1 of the Input XLR. Someone else took these pictures but they show that a wire will need to be connected between the case ground(Green Aligator Clip) and one of the Input XLR Sockets Pin 1. miketn This is the classic "Pin 1 grounding problem" referred to in the App notes at the Jensen transformer website and other sources. Just Google "Pin 1 problem".

That's interesting that there have been so many issues with grounding XLR balanced to RCA unbalanced cables. I've used female-XLR-to-RCA cables unmodified and without issue in every configuration since 2007 with no issues related to grounding. That's the reason why I listed the cable unmodified from Amazon, above. Maybe there are more issues with house-related grounding and common mode noise than others. Perhaps simply grounding the house power receptacles locally to the earth is another approach to the "balanced-unbalanced grounding issue". Chris Chris you have been inter connecting balanced and unbalanced equipment for 8 years + and never had any issues? You Sir are fortunate.

OK I'm a little slow on the uptake. What (or who) got cleaned out with Oxyclean?

It is most likely the power transformer and not a defective part. This is a very common problem, if you don't want to break the loop at the safety ground it must be broken at the interconnect which requires a quality transformer. http://www.jensen-transformers.com/product/ci-2rr/ Interesting you mention Jensen Transformers. There are resources on their website that will teach you how to locate and fix your ground loop problems. And they use real science not smoke and mirrors. And the real cool thing is they only want to sell you a transformer if you absolutely cannot fix your problem any other safe way. No affiliation with Jensen Transformers yada...yada...yada

Alota Friggin Fire Foam. LOL Sorry for having a laugh at your expense Mike.

Why would it make you angry? Michael, in the real world you will find there are a lot of people who will f*ck you to make a buck I used to believe in Karma, but it doesn't always go around Mark There is no such thing as karma. Evil and greed yes, karma no. I will burn my KHorns for firewood before someone steals them for $1000.

Nope. Lol, your answer was a bit terse. Care to elaborate. If there is a short of some kind in the amp that could cause a shock, would that not trip the circuit breaker in the power cord and cut the power. Sorry about the short answer, I did not think you wanted an explanation. But briefly, if you have defeated the safety ground anywhere in the cord supplying power to a piece of equipment that has the third prong it does not matter how close to the equipment a circuit breaker is. It will still not trip. If you have a 'fault' in your equipment and the chassis gets energized and the path to ground is open(by installing the cheater) there will be no overload current flow for the breaker to sense.

Nope.

Probably that sloth from a page back.

If this is a serious question I will attempt an answer: The cheater plug disconnects the chassis of the equipment plugged into it from the ground in your house. If there is a 'fault' in the equipment (fault defined as a short circuit of the hot wire to the chassis) the chassis would then be energized to line voltage. If you then touch the chassis depending on how good of a conductor you are to ground you could be shocked or in the worst case electrocuted. Admittedly in home stereo equipment the chances of a 'fault' are minimal. Many pieces of stereo equipment don't even have a third prong. But a good rule to follow is: If it has a third prong it is there for a reason, do not defeat it on a permanent basis. Find the real cause of your ground loop hum and fix it.

Does the AVR have reset button? Sometimes hidden. Press it, sometimes more than once is neccessary.

One is a 'straight' cable the other a 'crossover' cable. Most modern enet switches will self detect and work with either. Back in the day this was not so.

Just got off the phone with Carl, then I see this. Happy Belated BDay. For the next 3 months I'm only 2 years older than you

And this is immoral and nothing but greed run amuck. I don't care who you is you ain't worth $100 million a year, sorry your job is not 2 thousand times harder than mine. Just my $.02

Done. BTW, where you been?

'Firm' is an often misunderstood word

An XLR to RCA adapter will short pins 1 and 3 of the XLR end together. As I said in an earlier post this may or may not be OK for a balanced output.

Ay Carumba! These are not the same. One has a 2 conductor cable the other 3. The 2 conductor will force the inter chassis ground current and signal ground current to travel down the cable in the same wire. This MAY or MAY NOT cause audible artifacts(length of cable, noisiness of environment, magnitude of impedance mismatch, luck, etc....). The 3 conductor will give seperate paths for chassis currents and signal currents and ideally the chassis connection will be the shield of the cable. Yes it is still unbalanced but should yield the quietest possible connection. One must always think: 'where is the current going to flow?' This is for an unbalanced output feeding a balanced input. As I alluded to in my earlier post the balanced output to unbalanced input requires more data to implement correctly.

Dave, You beat me to it. I know you wouldn't want to steer the OP in the wrong direction. Eric
