Have a lead on a pair of ksm 2's for 140.00 or trade, are they worth it? If I go look at them anything I need to look at/check. Thanks!

That Tuba sub is way too big for my place, plus it would need to be finished, plus it's local pickup only, and so on. I've made a choice, and I went with the Paradigm Seismic 110. It has a sealed housing, but instead of being a rectangular box of MDF or plywood, it's made of a cast aluminum tapered tube, with four big chunky feet. It didn't come from China, it came from Ontario, so my money stays in the country, plus it can be easily sent right to the factory if a problem arises.
This happened once with my previous sub. After about 10 years of service, the amplifier quit. No problem, I just took it to Sound Hounds, the shop where I had bought it, and they removed the amp and sent it to the Paradigm factory. Within two weeks I had the sub back, better than ever, and it only cost $200. This is on a sub that was $900 when new, and still sells for $450-600 on the used market today.
Anyway, that's the old sub. The new one is part of the Reference line, and uses no off-the-shelf parts. It has a cool-running 850 watt RMS amplifier and a heavy duty 10" driver. You can see a cutaway of it in this test, around the middle of the page: https://www.avforums.com/reviews/paradigm-seismic-110-subwoofer-review.156
This next review gets into more detail, and has some proper tests, which reveal that the Seismic 110 has useful output down to 18 Hz, and even goes down to 16 Hz. While I'm still breaking it in, it does seem to have more punch than the old Paradigm sub, a PW-2100, and it goes way deeper. The tests in this review also show that the distortion is very low, especially in the 30-40 Hz. range where a bass guitar can reach.
Here's that review: https://hometheaterhifi.com/reviews/speaker/subwoofers/paradigm-reference-seismic-110-subwoofer/
As well, I got the ARC kit, which consists of a microphone, a stand, and some software. The microphone plugs into a USB port on the back of the sub, and the kit is claimed to be able to tune the sub to compensate for any room issues. I'm looking forward to checking that out.
Finally, I got a great deal on the sub, and now I'm considering whether to go for a second one, although for the levels that I normally listen to, this sub may be all I need. Thanks for all your advice and suggestions.
2 subs are not always about spl but a more balanced sound/bass output. I would listen to the first sub see how you like and how it fills the room.

This is what I have. https://www.homedepot.com/p/RYOBI-2-6-Amp-Corded-5-in-Random-Orbital-Sander-RS290G/205105594
I found that the faster I moved the sander, the more material it removed. For the most part I just let the weight of the sander do the work and I just guided it back and forth.
I have looked at those but the- orbital-keep me away from them. Now I'am thinking the corners of my rectangluar pad sander are what caused the swirls. Thanks, I will have to try one of round pad sanders.

150 grit is pretty heavy. I'd be careful with that, or go to a finer grit. I have always used an orbital sander with light pressure, again, with the grain.
Curious which brand-model? I never had much luck with them fine sanding, but then mine is the old rectancular style. Might be time for an upgrade.

Alright, after more reading, I cancelled my order of Howard's products. After reading Gary Anderson's post abt using boiled linseed oil, I am highly interested in that. Stunning color and just phenomenal looking results. I can get the oil locally from HD but will just any ol' boiled linseed oil work? Where can I find more information on this process?
Also, I'd be interested in hearing some advice on sanding. I've seen some people saying to sand with the grain using 0000 steel wool but I think Gary said he used an orbital DA sander with 150 grit(?) which I have access to. Would be open to any advice here.
Personal I have bad luck with orbital sanders, every time I used one they left swirl marks on project. I sand by hand with grain or on tough projects a belt sander. Jim, above has some good advice.

Would it be possible to move the tv to the wall left of where it is now. If so I would do a 5.1with front height speakers.
The way the room is now you have the distance for a 7.1, but rear speakers might be to close to people on sofa.The side speakers I think would be hard to balance since they would be mounted an unequal distance off center.
I would switch tv/furniture to the short wall and set up as 5.1 with front height. The way it is now on the long wall I think it might be hard to get the speakers to balance correctly.
-
If you could post room size, H x L x W. Are there open areas like hallways or open kitchen ect. Pics of the room where HT is to be set up would also help.
Needed info to detrrmine how /which set up (7.1or 5.1)is best for your room.

I have a pair for sale. They have been only mounted for testing, otherwise brand new.
I believe they are one of the recommended drivers for the Super Heresys
They sell for $140 each. How about $150+shipping. for the pair?
Where are you located?

My setup is pretty different than the other 402MEHs... I would ask Chris A to assist you, he is the expert on the k402MEHs.

Does your screen always come down in the same position...so it is always in focus? I ask this as this will be my first non fixed screen.
I bought a use motorize screen, mine has/had limiters that could adjust the up and down location. It was located on the left end cap of the screen.
Make sure your screen is level, my was off about 3/4 of an inch and was noticable,11 foot screen.
What are your intial settings for your set up. ( crossover and slope settings if your have them) Are you getting any harshness from the EV's? Thanks, l'am working on something similar.

No...This is a tradeoff between length of woofer ports and their width. The woofer ports (the "off-axis" ports) affect the combined off-axis polars of the entire MEH loudspeaker. Longer/narrower ports are a bit better at spreading out and minimizing the reduction in extreme off--axis SPL response around frequency band that corresponds to the 1/4 wavelength distance from the throat.
One of the no-no's of MEH work is to put too large a port across one wall of a pyramid-type horn (like the K-402). You'll get a drop out in off-axis polars that corresponds to that frequency band. Making the off-axis ports too small affects the efficiency of the woofers, too large affects the off-axis polars.
These are tradeoffs that many amateur MEH builders apparently are not paying much attention to. I try to pay attention to them.
BTW: the tradeoffs that are made for MEHs are far less of a compromise than using separate horns like on "conventional" loudspeakers...in terms of the resulting sound quality and issues with lobing at the crossover frequency bands--among other issues such as time misalignments.
Chris
Does the location of the port affect the sound? Looks likes yours and negatons are center a 1/3 of the way up up the side of the horn.
Are these going to be a 2 way design, haven't seen any mention of a separate tweeter. Thanks'

They both worked good for me, so one is not really an upgrade over the other. The main difference is the dispersion angles. The choice might be to use the 17x11 for a narrow listening area, or the 18x10 for a wider set of chairs. The shape of the front flange on the 17x11 can be a factor if you want to install grill cloth.
Thanks! The 18 by 10 is shorter in length but 17 by 10 fits better on top of my chorus ll. I like the sound so guess I will stay with them.

Chris suggested I use a 1 3/4" holesaw instead and make them longer for my setup...they are still a 10:1 compression, just a little smaller diameter.

Did Chris change the holes because your speakers will be standing up right? Looks good so far, looking forward to seeing finished cabinets.

This thing looks very interesting and I ordered a set just to see.Looks to be very close to the Faital HF200 everyone raves about.
Textreme a new fabric being used in speakers. Read an article on it not too long ago, looks promising. I will be looking forward to your review.

I have 2 of these and have used one on the F20 for years as have friends that I've built F20's for. You don't need a lot of power for that sub to shine, you can trigger it and the controls are all on the front panel for phase, gain and frequency, what else do you need.
Thanks again carl!
Amp does look nice, will have to look into it next month when I have more cash. Never really liked plate amps.
For now I am going with the yamaha, only 40 bucks so really can't go wrong for a temp. solution. Thanks!
-
I am looking at a Yamaha ax 592 integrated amp, 100wpc with 18 hz low pass filter. Figure I could use my avr for high pass filter. Would this amp work for .my f20, I can pick it up cheap.
Would only be a temporary till I get at little more cash for a bigger amp. Thanks!

Left surround speaker. Using the 18" x 10" horn here, to compare with the 17" x 11" on the right surround.
These are zxpc right? Iam using the zxpc 17 by 11 on top of my chorus ll and really like the sound. Do you favor one horn over. Thought about trying the 18 by 10 but not sure it would be an upgrade.
-
You could look as some of the zxpc horns, I am running the 17 by 10's on top of chorus II. 18 by 8 (I believe) are also popular and suppose to have polars close to the k510. He is an Ebay seller and average price is around 40 bucks a horn + shipping.

Ksm II any good

I was thinking of using them for rear surrounds in a 5.1 system. Was hoping the wedge design would save a liittle space when placed in a corner up right.
Was kind of wondering how they sounded? 2 way design, one review compared them to older cornwalls?
