Claude's quarter pie horn. You could build one that stands vertically (woofer firing down), and shorten the horn flare to 2 feet. My surround QPs stand vertically and work great. I would imaging that being that short would mean that the horn would bottom out 90-100 HZ instead of 50-60 HZ, but an F20 can handle that.

Uncle Fester!

I spent several hours today playing test tones and measuring with REW. After getting the LR channels sounding superb with the Xilica I decided to tackle the other channels in my HT. I am using a pair of Ashly 3.24cl units which are not nearly as user friendly or capable but having learned A LOT over the last day the results are impressive. Speakers have location-ally vanished. Everything is super clean, music and film sound awesome! Many, many thanks to Chris A for sharing his knowledge. I owe you a beer or 3 for sure.

I also wonder if the odd readings on the bass bin could be from the Integra pre/pro I use. It switches output on, with an audible mechanical click from the unit, when it detects a signal. There is a slight delay, maybe affecting the beginning of the sweep?

The bass horn is a quarter pie with an Eminence 15c driver (60-600 HZ), JBL 2360 with EV DH1A drivers (600-6000 HZ), QSC horns with Dayton drivers (6000-20000 HZ). I hope this is the image.

What is this telling me?

With the above corrections. Better, though not sure how to interpret the bottom zig zag.

More zoomed out. Sorry to be so slow/dense, thanks for you patience.

Now I think I have something. 5 ms delay?

Is this something?

I assume I should be looking hard at the crossover points (in my case 600 HZ and 6000 HZ)? Using the spectrogram values that you show above I don't see anything resembling your time mismatch. I am I still not getting something, or do I already have it very close?

This is my right channel. Not sure what I'm looking at.

The Xilica sounds quite good, already a noticeable improvement over the Ashly units. The computer interface is intimidating at first but seems well laid out and I was able to easily input REW numbers for EQ. Next is to more accurately get time delay figures. I am using my old numbers from the Ashly units which were derived from measuring with a tape measure and guessing a bit. Any tips on getting that accurate would be appreciated.

Thanks for all the info you put out here! I just got it hooked up and actually working! I will be attempting to use REW shortly. I have such a huge tangle of cords with my setup (16 channels) that getting it hooked up right is taking time.

Well, my XP-3060 arrived yesterday, and as luck would have it I have some time today to try to figure this thing out. There is an overwhelming number of things you can do with this thing compared to my Ashly units. I know I am going to need help when I can figure out what questions to ask. Setting up crossover points will be task one. This unit is going to run my LR 3 way front speakers.

Sale pending

Open to offers. I would rather sell in here than on Craigslist!

The Academy is great! Using it in my KG4 setup and it is really matches well.

I am selling a Harman Kardon 630 twin powered receiver with matching wood case. The receiver is in good operating condition with all lights and functions working. I have not had any work done on it so given its age a bit of TLC is due down the road, but it sounds good and is functional as is. The matching wood case is in very good shape. I would like $200 for it , and would prefer local pick up (West Chester, OH), though I might be willing to ship with buyer paying shipping costs. This is however a big, heavy unit and shipping would not be cheap.

Pioneer PLX-1000 Can be found for around $600. Nice sounding TT, solidly built. Gives you several hundred to spend on a cart and still stay under $1,000. I have mine pared with a Clearaudio Arum Beta cart that I picked up on Audiogon. Sounds good to me.

I will pass this along to my violinist wife. She will be amused to know she can't hear high notes, esp. at night.

My K-horns image quite nicely. I do have them well setup, 20 feet apart and tucked into corners. The imaging is as good as I have heard with any other speaker. Magnapans that a friend of mine has do extremely well too, but no dynamics. Setup obviously is a big part in this.

PM sent. Did this on my phone so let me know if you don’t get it.
