  1. If you already own any of these, better to keep what you have. Money better spent on upgrading the front left, right and center channel speakers.


    If not....of these 2 speakers, RP-600M are better....unless you need wide dispersion. If you need that or not will depend on your room, seating, and speaker placement. Most cases use wide dispersion for side surround, not surround back. Also consider that wide dispersion in an otherwise acoustically untreated room may have significant disadvantages. Again, your specific situation is unknown, and therefore may vary (greatly). 

  2. Location: Fall River, Wisconsin 53932

    Price: $1000


    MSRP $3600

    W/ CPI inflation factored in would be $5,471.62 today.


    This Class AB amplifier is designed with a very high bias offset. That provides appoximetly 25% of rated power (900W) to run in Class A before it switches to Class B. So you are getting about 37.5W/channel and 75W/channel bridged Class A power. Don't believe me? Look at the specs. The idle power is 225W. That is how Class A is designed. That is why some have described Classé as having a "Tube like sound".


    I think this is perfect for someone who appreciates the quality that Krell, Mark Levinson, Bryston can bring, and who are also not about to pay those prices. Classe brings alot of performance at a more reasonable price point. Classe has been favorably compared to Theta. May slot in just ahead of Aragon. Ahead of Parasound too.  Definitely ahead of Emotiva, Outlaw, Monolith, Integra, Denon, Marantz

    I like those L20s.  I just bought a pair.  I should have contacted you first. 

    The other pair of L20T3's are chained to the ceiling. I would've hung that pair you spied too, but I need a new driver.


    I felt the need to and did collect the entire series.






    Been there done that now I am over it. I have 4 250Ti's now.


    You can see the L40T3's to the left. Super rare in oak. 1989 only.

    I totally agree. I had CWIII for a few months. The hump/coloration/resonance it had interfered with the midrange resolution.  Things became blurred and wooly compared to either my Forte I or Forte II, or even my Heresy III speakers.   I do not trust the CWIV will be much better in this area if it is not braced to address this issue. It probably will not be as I think there are far more Cornwall lovers than detractors.   I think some people like that resonance because it gives the illusion of a BIG sound.

    I agree with this statement so much it is worth repeating a third time. This is why I am a proponent for developing a Chorus III. Now I would like to hear thoughts on baffle diffraction and edge diffraction in a large box. My 30 year old JBL 250Ti solve those cabinet diffraction issues, are internaly braced and filled, and look good all at the same time. The only thing getting in the way of utilizing these well known solutions to well know issues, that I can come up with, is cost and profit margin.

    That rack is looking great! Very well done! I'm can't wait to see the completed project. I had the same thoughts about "why audio racks are so expensive" when I built my 2-channel audio shelf. There wasn't a shelf on the market that was exactly what I needed, so I built my own. I used very heavy maple hardwood and stainless steel tubing for the supports (200 lbs).

    Thank you. I really appreciate that. It will be a while longer before I am done done. I have a small workspace, so I did not have enough room for all of the pieces to be finished all at once. Some of the trim on the rear, and decorative side pieces will be added on later. I have to go through the exact same finish process all over again. I think there are something like 11 or 12 coats of various products with curing and sanding in between each. Don't worry the rack will up and running first.


    I love what you did there. Tubing is great, feet are a nice touch, the dimensions are definitely custom. I know that maple butcherblock is not cheap either. 


    I went through a lengthy process trying to match oak to walnut with the "Flexy" racks I built for my other system. I also needed something custom for integration across the front wall. Here is a pic to my other systems diy racks.

    I may be selling mine if you're interested. Not sure about the sensitivity but they worked very well for atmos when I had high ceilings and mounted them

    I may be interested. Send me a PM when you get around to selling those.

  8. Well, there was this one project where I successfully accomplished isolating a high frequency laser for a manufacturer. By using a system involving heavy duty spring isolators, and a suspended monolithic slab of concrete weighing 120 tons, the laser was ultimately immune from any vibrations transmitted through the ground above 2Hz.  


    Ultra low frequencies excite the materials around them, causing vibration. This vibration travels longitudinally. How far it travels depends on soil type and strength of the source. Likely your neighbor is hearing this vibration. By isolating the source, you are isolating the vibration, thereby reducing the strength of ultra low frequencies being transmitted to your neighbors foundation. These ultra low frequencies cannot be heard, but you can definitely feel them, and especially you can hear the china in the cabinet rattling.


    Hope this helps. Good luck


    Oh, and OMG what a subwoofer stack!😲

    What amps are you using?\


    I just purchased 2 Monoprice Monolith 12" THX Ultra subwoofers. They are sitting on SVS SoundPath Subwoofer Isolation feet. Basically my room is on top of a concrete slab. Never even plugged them in yet. We will soon find out what my neighbors thoughts are. hehehehe

    Yes, I believe they're grill magnets.

    Wanna bet? I on the other hand believe they're the metal inserts that the magnets that are attached to the grill frames bond to.

  10. Got a new Weber Spirit E-310 propane gas grill. Up in the top rack, had them pull the pallet down, scan the price. Last years $500 model is showing clearance price $300. Even the store manager did not know that deal existed. If you can find last years model, you can get the same deal. The store I went to had 21 in inventory, so the warehouse is dumping them and sending them out to select locations.

    Here is a link you can search for one near you- if you are interested.



    Genesis II @ 2x the price even on clearance just wasn't doing it for me.

  11. Just took the preliminary weight measurements. I estimate the final weight of the rack to be approximately 175 pounds total.

    Looking good Im about to redo mine as well. Looking at your materials I think ours will be very similar.

    I could have added another $200 to the total bill had I choosen THESE these for the sides.If I went this route instead, I would have cut vertical slots along the sides for added ventilation, and some additional aesthetics. That would have brought the material list up to $600.  Just using up what I had here instead.


    Totally understand now why audio racks are as expensive as they are, even though the prices seem insane for what they are. My issue was more about getting exactly what I wanted. I just could not find the size, color, style, shape, materials, casters, etc. that fit what was in my mind. If I was asked to build one of these for someone else, I wouldn't do it for less than $1200. Good luck with your build.

  12. Not quite perfectly flat yet. I don't really care if it ever gets that flat. Just want those high grain ridges gone so when I slide a 100LB ampifier across the shelf, I don't drag across some grain possible lifting some finish, or color, or even a scratch.


    It was the first time for me using the AquaSeal product. A bit of a learning curve. Started on the bottoms of course. I eventually got a good technique down. More tedious than I thought it would be. Worth the effort, but I stopped after 2 coats. There is maybe 100 board feet of material here to finish. I eventually got one coat of General Finishes on everything, then called it a day.
