I have finally gotten to attempt a center channel build that will better match my Oris horns. I currently use my Oris horns with Tang Band 1808 drivers and have been very pleased with the sound and performance. The frequencies below 200Hz to 50Hz are handled by my open baffle wave guides. My current center also has an open baffle wave guide, but runs to a higher frequency so I can match my 2" compression driver and horn. My goal has been to create a center channel that will also use a Tang Band 1808 and have similar performance to the mains with good timbre matching. I spent quite a bit of time looking at similar horn builds and had been planning on building the top section of a Lowther TP1. However, I decided to try and build a horn that has the same curve as the Oris horns. I made an initial template with cardboard, then transferred the dimensions to 12mm BB. I then used that template to cut all my 18mm pieces in order to build the horn flare. The plan is to use this horn with an open baffle as well since this is how my Oris horns are running right now. I also decided to try and stain the BB vs. my usual black lacquer paint in hopes of getting a nicer finish. I am in the final stages of the build and will run some frequency sweeps as soon as I can.

I figured I'd try Marantz's website (I know, to easy). Go figure that they don't a manual for this particular unit available. I guess that would be to easy, wouldn't be? I then did find this link: http://audio.manualsonline.com/support/other/stereo-system/user-contributed-manual-for-a-marantz-home-stereo-system-182512 However, when I tried to download the PDF, but the stupid thing wanted me to sign up for some bull$#!+ account. No thanks. If you want to try, that is your prerogative, but I am not going to give out my name and email if I don't have to. Did you try contacting Marantz themselves? Maybe they can send you one or point you to where to download a PDF version. Marantz Customer Service hours: 9:00 AM to 5:00 PM ET, M-F Tel: 800-654-6633 If that does not work, try...

Ben and family are fine. He friended me on FB and I sent him a message as I was concerned about how he faired. I'll tell him you asked!

Now that I look at it closer, this is a copy of the service manual. I'll keep looking for the owners manual.

Rick, I'll join in on the hunt.

My post was not an exercise in precision, but rather, what I have found to be true, which is spending lots of money, watts, and/or cubic feet of space to get GREAT BASS. The smaller the room, the bigger the challenge in a home. In other places, the challenges occur when the rooms get too BIG or there is no room. Normal living/family rooms provide 12 db/octave of gain below about 30 Hz. That is a given, irrespective of where the woofer is located in a given room. However, locating TWO front and rear wall centers, or better yet having two more in the center of the side walls, will, not only, increase potentical ouput by having more cone area and power amps to work with, it will make the bass response WAY smoother all over the room. So basically the IDEAL is 4 subs: one in the center of each wall. It's all relative.

lol. The attached is copy written material, and it wasn't free. I'll share it here, but I would appreciate not seeing it pop up on any other forums. Thanks. Speaker_cables.pdf Speaker_cables(3).pdf Measuring_speaker_cables.pdf RF effects on AF.pdf Cables_RC.pdf

Do you have the wire chart, or graphs, that are correct? Your statement is worthless as is.
