My Denon X-4000 AVR sounded fine, but I wanted to use all XLR interconnects with my active crossovers and multiple outboard amps, so I bought a Marantz pre-pro. I then gave the Denon to a friend, who now has a nice sounding home theater with his Klipsch in-wall and ceiling speakers, and I have a system that I am happy to listen to AND enjoy looking at the professional appearance of my hardware installation.

I think I will cut some horn holes with my new plunge saw.

You are correct about the frequency range of musical instruments and the capabilities of the recordings, but JBL recommends the application of the 20 Hz high pass/subsonic filter on the 4645B ported bass reflex subwoofer referenced at the top of this thread.

Your Stop Saw is a fine piece of machinery, and its safety features are impressive.

You may want to download the Crown HiQnet System Architect software and then plug your Crown into your home computer via USB cable. This is not required, but will be easier to navigate the menu and read your settings, compared to the tiny front panel display on the amp. I have not used a DSi, but I think it should do what you want.

I once replaced a Black Widow driver with a Peavey Low Rider 18" subwoofer driver and it was a big improvement in low frequency response.

I like your saw, and the subwoofer you built with it.

An adapter is not really needed with your existing hardware. Just take an inexpensive RCA wire set, cut off one end and strip the insulation, insert the bare wires into the Phoenix connector and tighten the set screws. The inner wire should be the positive + conductor.

I recommend connecting The Marantz PM8005 pre-outs directly to the Crown DSi 1000 input using a RCA to Phoenix adapter, then scroll down the DSi 1000's onboard menu and selecting the pre-sets for the JBL 4641, the newer version of your fine subwoofer. That should get your system playing just about right without buying an outboard crossover, since the La Scala does not really need a high pass filter (bass cut filter). Later, when you become more familiar with the Crown's built in DSP, you can select the CUSTOM mode to apply your own settings, the important parameters being JBL's "B6 filter", 6db boost @25hz Q2, Hi Pass Filter (subsonic cut) @20hz. Also select Low Pass Filter @60hz to the subwoofer since your La Scalas will handle everything above 60hz.

The owners manual http://assets.klipsch.com/files/RP-HD-Wireless-Extended-User-Guide-v07-ENG.pdf, does not specify compatibility with other brands of WISA equipped wireless speaker and audio, but leads me to believe that it should work for you, according to the set-up instructions.

You noted the Cello Palette EQ curve in the past when asked about dealing with internet source streaming music. Is that what you are recommending again, or are there other similar options to consider.

The 4 1/2" Worx saw would be convenient if you are standing on a ladder, or cutting a 2 x 4 that is attached to something. But most hand held circular saws are not for precision work. I like to use my 12" sliding compound miter saw and shop dust collector in the garage, or my table saw, whenever I can make a reason to cut a piece of wood, so that the cut is square, and if cutting duplicate pieces, that they are all the exact same length. Different tools for specific tasks, the ideal is to have all the right tools, and operate them safely.

Your going to have a really nice setup, right around the time your speakers start playing some tunes.

The Rockwell plunge saw is handy for cutting sheetrock for installing in-wall speakers. Set the proper depth and saw the hole with no fear of nicking any wires or pipes that might be hidden in the wall cavity. The blade is so thin that dust is fairly minimal. I have used one for trim and thin panels also, but I probably would not abuse the little saw by cutting 2X4s. The price in your linked ad is so good, I just ordered one for myself.

Went outside after midnight to look at the constellations and to observe 28 db SPL on the meter. After a while I could faintly hear the hum of a pole mounted electric transformer about half a mile away, then I noticed the sound of a solitary car's tires rolling down the asphalt two lane highway a couple miles away. When the car travelled a mile or two further and the silence returned, a breeze caused some autumn leaves to rustle and made me realize that my neighborhood is not as quiet as I thought. Glad I have Klipsch speakers to drown out all the background noise around here.

The Hoh Rain Forest is a quiet place when it is not raining, but the dense vegetation does absorb any stray sounds during the dry moments..

I looked at the specs for the THTLP and it is impressive. Should sound good in your place, and I am guessing you have a big room because each single THTLP is a large box.

Pictures of the original wires and the speaker wire connection panel would be helpful.

I value your opinion on this. I have never seen or heard one, so am curious, how large is, and how much does a new Tuba HT Low Profile (with amplifier) cost, delivered?

The subwoofer's performance looks good on the manufacturer's supplied graph. The product description lists a lot of good design features, for this style of subwoofer. Thanks for alerting me to an interesting new product.

Klipsch should exhibit the Jubilee at the Consumer Electronics Show.

That explains why my La Scalas sounded better outdoors at high SPL's.

Is this what is called "collapsing polars"? So a horn advertised as 90x60 degrees dispersion may become 180x90 degrees at lower ranges, affecting the frequency response in a room with hard walls?

Your new Forte III speakers look really good.
