I use a Fluke 112 and have for years. Kind of a middle model for them and will also read capacitance.
I bought a Fluke 117 which is supposed to be better and also reads capacitance. Compared to a B&K 885 it is not accurate and by the time you get up to say 20uf has problems. No ESR measuring either so rely on these Flukes for a general idea but not an accurate idea of capacitance. That has been my experience with the two side by side on my workbench regarding capacitance. Otherwise Fluke seems to be dead on.
Klein and Amprobe make multimeters with good reputations but Fluke is the most common from what I see the pro's use around here. I have had cheapo's before and I got what I paid for and the Radio Shack one was half the price of the Fluke 117 so it was not free either. Cheap flimsy garbage compared to the Fluke though and died pretty quickly. I like tools that work right and are durable.

OK K1 and 2 owners tell me why you prefer an older amp to current offerings? When I was looking I wanted one I could hook up directly to my PC with RCA inputs on the amp. What sound levels do you play at that you need that kind of power? What are you saying the old ones do the new ones don't do? The Crown xil1500 with 350 watts 8 ohm is new for $300 at Sweetwater and the used K ones are $300 plus on EBay.
Personally I have only turned up my single xli800 all the way with any of my speakers one time. I put on my shooting hearing protectors before I did so for my friend who just wanted to hear the MCM's as loud as I could get them. It was ridiculous and I turned them back down after a couple of minutes because he had no idea what he was doing to his ears.

Add another loop to the P in PS Audio and it becomes accurate.

I just ordered my second Crown xli800. Honest clean 200 watts per 8 ohm channel and if you turn them all the way up on those you better have ear protection. I find for my tastes I hardly ever even crowd 150 watts and these things just loaf along. Like your Pro speakers Pro amps are to me the better buy. $225 delivered too. Even though I am getting a Xilica setup for my SMWM + 402 the amps I will be using are two of those xli800's.
You remember Bonehead talking about headroom in pro speakers over the Heritage line? Same thing for amps too though anything with bells and whistles can climb in price pretty fast and you won't get things like Audyssey to play with.

It's not (usually) a typical occurrence, but if for any reason the port gets overloaded it's definitely something that gets one's attention. Think along the lines of "below tuned frequency information at high levels." A drone may clack in such a situation but I think it less likely to happen, at least not as readily.
Most of what I hear is Klipsch and the excursion is pretty small so not a tremendous amount of air volume moving.

You've never heard a port make self-generated noise while performing its task?
No to be honest I have not that I could identify. Maybe it is there but to me all I hear is a speaker that sounds different than others do which is what I expect anyway since they are different. No steam engines or puff puff noises I can tell with speakers I have had.

I'd say for $6 give it a try but honestly I think I have to side with Jason on this one. I recently compared the Chorus 1 to the Chorus II and I actually really liked the Chorus 1 sound quite a bit better in my room, much more tight and realistic sounding.
Yes to this and the big bonus of placing your speaker anywhere and it works right and is not corner dependent.
2 hours ago, jjptkd said:Passive radiators are ports from what I understand, typically used in situations where a standard port would be too long for the cabinet and both Chorus models use the same woofer.
90 degree angle and then extend from there perhaps? How long does it need to be anyway?

I guess I am missing something here. I see this term used but I can't say I have ever noticed anything like this with speakers I have had.
I don't have a set of Chorus I's to play with but I know sometimes blocking a port can lower hz. I had a pair of EV tl440's and if you wanted the lowest hz you had to block one of the two ports. Playing with a program called BoxNotes last night which was indicating on the KPT-456's if I blocked two of the four ports the lowest hz would drop more than you might think. I would take front ported over a passive any day and if this is right is just another reason in favor of front ports. You can tune these front ports with length and or covering one or more ports. With passives even though you can put weights on a passive and tune it that way you still have to use a corner.

You are ahead of me. I have never had my hands on the newer La Scala drivers.
-
Thanks for the concise info Bob, I never thought of Zee brackets. I like that new K-77D shape better than anything before and wonder why they did not make that change a long time ago. Now if they would just front mount the mid horn.
Are those screw hole centers still the same as the K-77M?
-
While working on these 456's I notice a piece of plywood inside the cabinet towards the top. It is fill width, starts about 4" back from the front of the motorboard and goes at a 45% angle down towards the back and ends just about at the back top corner of the input cup cutout and has a layer of foam on the down side slope. What exactly does adding this piece do?
-
OK can someone tell me why the La Scala II tweeter cutout is so darned big relative to the tweeter lens? What I am told is that the new tweeter just floats around in that hole and it sure looks to me like the screw hole pattern is longer center to center too. I know Klipsch has CNC routing capability and the tweeter is precision cast so what's the deal with the third world hole size?

There wasn't a tube in the port, only two holes cut in the front board.
Matthews documented quite a bit in his thread at the time. I always like a good build thread.
Great thread. I have a set of parts for a Chorus I and I have some 1" Baltic on hand for a build. I figure on maybe making it bigger depending on what the guys with software say is best. Like these the MDF was damaged and no way to repair.

It is infintesimal at this time.

Not really. There is such a small demand for these right now that it would not be worth doing. What I can do is modify the design to extend the screw tabs on each end to match the larger hole spread. They will end up being a bit more expensive too with additional material and cutting time but I imagine not more than say 15 or 20$.
These test pretty good and getting into making them longer but not being able to make them taller at the horn mouth would change that. If there is interest over time I will do so. Hoping to be able to test tweeters myself sometime later this year. I have the tools to do so I just don't know how to yet.
-
Interesting. It looks like I will have to design a new one for this with a longer tab on each end for the screw holes. Any idea why they are just floating around in such a big hole? What are the screw holes for on the motorboard? Are they pre-drilling the holes for the back side horn mounting screws?

Sounds like it would be a blast!
So, a bit of a rhetorical question..... if you have someone performing live through Khorns, does that make them PA speakers??
They have always been Personal Audio speakers as far as I know.

I am looking for someone who has the new La Scala II's somewhere close to southern middle Tennessee. I would like to come and measure the horn lens and the cut out in the motorboard. Apparently these are a different animal and require a different size horn lens. PM me please if you can help or know someone who can.

I don't think Dave is using MDF...
Talking to the guy helping me load last week and he said that they have a stack of 1/4" cover sheets about four foot tall each week from all the skids of Baltic they sell. He said they sell the heck out of it and most goes to speaker cabinets and the thinner material goes into high quality cabinetry. For people who want the very best. They are not the only seller of Baltic in the Nashville area either so who knows how many custom cabinets are built in Music City each and every week.

I hear patience is virtue. Rome was not built in a day. The watched pot never boils. Haste makes waste. Fools leap in where angels measure twice cut once.

He doesn’t want the old caps. He wants capacitors that are similar in type to the originals.
I get that but those would be Mylars or motor start right? My understanding is those are not so good.

I don't think the knobs are very attractive.
