+1 to that.

I have been shopping for some La Scalas myself. $1500 sounds a little rich. But maybe if they have a very nice cosmetic appeal and are electronically sound. Others here will say look for AA or AL-3 crossovers. Still it sounds high. My limit is $1000. Audiogon bluebook is $1230 which is an average price.

I think he was only talking about this response. Not Mustang's

Well the auction just ended. The La Scalas went for a cool $1000. Too rich for me considering the 4 hour drive there and back, the new crossovers, the time and materials to refirb the cabinets and the fact that I couldn't even audition them???? Those industrials are looking mighty tasty at $1200 obo.

I just found out these La Scalas have the AL crossover type. B. Crites recommends an upgrade to his AL-3 crossovers - Cost $365.00. So, $600 - $365 = $235 to 250.00 as a max bid I would think. And one or more of the drivers might need to be replaced??

These I posted the pictures of are about a 4 hour drive for me to get. The lister says that "all speakers and cones are mint and they work and sound as they should" but he also says they are in "very good shape" cosmetically.

Here's another...

Here is part of a pair of La Scala's currently listed on ebay. They look to be in bad shape cosmetically and there is only a picture of one of them. Any idea what they are worth and any guess what they will ultimately go for?

I used REW to calculate the PEQ filters for me and then I manually programmed them into the DEQ2496. The REW software works for the DEQ2496 the only trick is you need to tell the software that you are using the FBQ2496 as an equalizer. It works great. You "Measure" the room then you select "EQ". Then "match response to target" then Look at the "EQ Filters" it has calculated. I only had 5 PEQ filters so it was a snap to program the DEQ2496.The latest software is 5.09 beta or 5.0 standard release. I am using the 5.0 standard release. There is a MIDI interface from REW to EQ device but I didn't trust it since I couldnt explicitly select DEQ2496 as an equalizer type. Programming manually was a snap though no need for the MIDI interface. So programming the DEQ2496 was a 3 step process for me. 1. Play the 1/3rd octave test tones on the Rives TEST CD 2 and read them with my Radio Shack Analog meter. Adjust the GEQ settings on the DEQ2496. Then play the 31 test tones again while reading with the RS meter to make sure every thing had leveled out. This included the bass test tones. 2. Using REW and an ECM8000 mic play the sweep to measure the room/stereo combination. Let REW calculate the PEQ filters for me and manually program them into the DEQ2496 PEQ. The PEQ was only in the range of 20Hz to 100Hz. Tweak any GEQ settings that may be off from step 1. 3. Run a final sweep with the REW and ECM8000 mic to record the final results. Note I did not need to use the FBD on the DEQ2496. I am just running GEQ and PEQ. And then the fun part - listen to my collection to see how good all the music sounds.

This is the final waterfall chart. It shows minimal ringing and level bass frequency response. I got the author of Room EQ Wizard, John Mulcahy, to comment on the chart over at the hometheatershack REW Forum and he said it "looks pretty good []" All in all, integrating my Sunfire sub to the Heresy 3's was a straight forward and fun project. And now I get to sit back and enjoy. Thanks to Quiet Hollow who first suggested me getting a Radio Shack analog SPL meter. Thanks to willland for getting me one (Radio Shack analog meter) even though it is discontinued. And thanks to artto for suggesting me getting the Behringer DEQ249 and helping me figure it out. There are lesser models than the DEQ2496 but it is perfect for me because in addition to the Parametric EQ it also has Graphic EQ which I chose to use for the higher frequencies. Thanks to John Mulcahy for writing REW and providing it for free (donations optional). And finally thanks to all the other posters that commented and helped me out. I think the Heresy 3/Sunfire combo is better than Cornwalls alone and dare I say it, I think my setup will rival a pair of La Scala's alone with better WAF too.

After GEQ and PEQ:

Before Equalization:

This is my new frequency response chart as composed by Room EQ Wizard. Green is with no EQ. Purple is with both GEQ and PEQ applied. The region around 2KHz I over equalized so I fixed that and didn't resave the graph.

I bet room acoustics (reflections etc) causes much more variablity in performance than subwoofer manufacturer does. That's why I have been spending my efforts recently on being able to measure my listening room/stereo combination and equalize out problem frequencies.

Artto, thank you for your reply. Everything is becoming clearer. I received my DEQ2496 today. I am going to get a mic cable by mail Monday. So in the mean time I wanted to play. The DEQ2496 was a snap to cable up (Main In and Main out). I powered it up and restored it to the initial factory settings. I then played the Rives 1/3rd Octave Test Tone CD and checked the levels on my Radio Shack analog SPL meter. For each test tone/meter level, I adjusted manually the DEQ2496 GEQ 1/3rd Octave. The graph is now the equalized frequency response of my stereo/room combination. (I made sure to primarily cut not boost). When I get my mic cable and USB Mic Preamp with Room Eq Wizard, I'll be able to improve the resolution using PEQ and FBD.
