You might consider the Fletcher-Munson curves. https://en.wikipedia.org/wiki/Equal-loudness_contour
These show that even average ears need a higher acoustic level (phons) to perceive low freqs. Therefore by these standards everyone is hard of hearing at low freqs.
Let me suggest you try some in-ear headphones, I have a pair from a cell phone purchase, to try the tones on the link which was posted. I can hear 30 Hz without problem on my laptop in a quiet room. OTOH this is where many big speakers are rolling off in acoustic output rather quickly. Therefore speakers have falling output and ears have falling sensitivity. It is a losing battle down there.

I certainly agree with lamp cord (zip cord) maybe 16 gauge. This is PWK's wisdom.
I'll suggest a new receiver from Fry's or the like particularly what you have nearby. Check out the store return policy. Fry's in Dallas was good to me years ago. You get a warranty.
I don't want to spend your money for you. But as you go up in price from $150, to $200 and $250. you get a lot more features including sophisticated equalization which could really help the Heresy bass. In all things I avoid the rock-bottom priced units with limited features because in the future I wind up moaning that I should have spent just a little bit more. Penny wise and pound foolish. Or as Car Talk said, "It's the stingy man who pays the most."
You should give some thought about what you will use to feed the system. You can start with a Bluetooth link from a cell or laptop. That is basically free.
If you have a big screen, or not very big screen, you owe it to yourself to hook up your rig to the screen. You'll never go back to the dinky speakers in the screen.

I'm glad to hear that people like Motorola. The Galvins have done a lot for IIT, one of my schools.
I had lost faith in Moto a bit. My niece has a Moto on a discount carrier and probably poor signal strength and it might have have be drowned a few times. The system is a muffled mumble machine. For good or bad I'm her telephone caretaker and have to work with it from afar. But so now I know it is not inherent in the phone. Thanks again to the Galvins and excellent Moto products and support of IIT here in Chicago.
By way of background: I enjoyed the HP200LX pocket DOS computer very much decades ago. Half a CGA screeen in LCD and a fabulous QUERTY keyboard. It folds like a laptop. I'd love a cell like that.
So I've got my eye on the LG dual screen. It is marketed for multitasking and gaming. It seems to have a setting for QUERTY keyboard on one sceen which is good for a fat fingered guy like me and the high rez OLED screens. One reviewer mentioned they're viewable in sunlight when goosed up. I dunno.
Funny story there. One time I was at the shadeless lakefront promenade when an important call came in. I had to make excuses for delay, take off my backpack, and put my jacket over my head backwards to see the cell phone screen. I got the assignment but looked like an idiot to onlookers.
Anyway, the LG looks like a winner and less expensive than similar units on the market.

Okay. We've all had tragedy, and we all need sympathy. It is good for you to share with us.
But in the end we have to strap on a pair and be a man.
Ann Landers had some correspondent who was moaning. Ann replied: Count your blessing and quityerbitchen.
King James Bible
Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest.I take that as advice that our work is the solution to loss and frustration.
Sorry if I'm preachy.

Yellow Jackets. They're miniature one-fanged flying rattle snakes. I was stung just under my eye when in 8th grade and swelled up like a pumpkin face; and it hurt a lot. The problem was fruit trees in the back yard.
I'd think the problem is finding the nest. In any event there are several YouTubes about using a shop vac. https://www.youtube.com/watch?v=ytMcIpIRL3w
I would think they'll be back unless you can kill the queen.
There does not seem to be info on whether UV will attract them into a zapper. In any event, this was a marvelous commercial.

Is that Schwartzman replying? A "3" in "2" land? Hi there fellow Ham.
Back to the original issue. If you're looking for more bass Belle and LaScala really are not deep bass performeres but would make a good center between the EV versions.
There are dimensions here if you hunt around. Maybe someone will point you. Andy showed a very accurate LaScala.
You should look at the Klipsch.com video of the LS II. Getting the doghouse right is difficult for the LS. If you look you'll see that Klipsch used plywood plates at the top and bottom to allow the doghouse to be constructed as a unit before it is slided into the box for the LS II.
Re the Belle. Very beautiful. It is 18 inches deep and is built to use the K-500 mid which is very rare on the market. Therefore you might be better off building the LS type which is about 24 inches deep and takes the less rare K-400.
OTOH, the front point on the LS is the result of two very difficult to cut angles. I've used an element on the front like the Belle which eliminates that issue and you'll have an LS which looks like a Belle in this regard

From the title I really thought you were talking about the base partof the box rather than the low frequency bass. Gentle grammer correction and welcome to this happy place.
Some will help you.
In my view, it is better to use a bit of equalization rather than modifying the speaker.

Long ago I saw a guy on the bus reading a magazine call Bass Master and actually thought it might be about speakers. Hmm, maybe Roy reads it. Smile.

I like my Quartets. Circumstances forced me to sell my Forte II. As things turned out my circumstanes were not that bad but at the time it had to be done.
My favorite experience with the Quartets was to drag the not so big, big screen up to the couch and put the Quartets on either side. StarTrek TNG is my secret enjoyment. It was ear opening to hear the sound of the engines in the background from scene to scene.
No one should hesitate to purchase the Quartets, IMHO.

I've made Beef in Burgundy per the recipe of the Frugal Gourmet. You can Google. Basically chuck chunks browned in bacon and then stewed in red wine. Then at the end add sautee'd low sulphur onions and mushrooms. Double the 'schooms, I say.
I found that too much wine leads to too much cooking and letting it boil off and that overcooks the beef. It might be that the French put it in a 180 degree oven for a longer time.
The FG says to serve with way too much wine and you'll be famous in a half hour. True.
I've seen recipe for a steak size piece of beef served in a shallow soup bowl. It is on the list.
Any music will do.

Long ago in one project:
aI put down a bead of hot glue (like spaghetti) on the frame and let it cool; then put the fabric down over the frame maybe with some stretch;then applied a clothes iron to the fabric to melt the hot glue through the fabric. You can iron down one edge and then stretch the fabric to the other as you please of course.
It worked for me.
I haven't tried reversing the process but it should work to adjust thing. As they say, experiment first because some fabric may melt with too hot an iron. Aluminum foil on top of the fabric might help.
At least you don't need a hundred staples! It should work on Masonite.

There may be a different issue here. The virus IIUC will not multipy and spread outside a host. OTOH, the virus can live in little blobs of sneeze (micro sneeze?) which can be physically moved. This is the basis of the need for hand washing and masks for physically coralling sneeze.
Is there information on how any virus survives on a nominal "dry" surface. We see data that it survices on surfaces. But do they survive with no H20?. It may be an empty question because in the real world that does not happen.

I'm with you Thebes in grouchyness over cell phones. One friend in the burbs is fond of going downstairs to do laundry and put me on speakerphone. Ugg.
When I become king the standard will be to simulate a twisted pair on a Princess Phone, like in the good old days.

Maybe someone can clear this up for me. The implication above is that there are errors in the digital data as it is copied from CD's and other digital media. Some years ago we had a fellow saying he had a 4th generation of a music file and of course it sounded bad (he claimed) because of errors.
My question is therefore whether errors are corrected, perhaps perfectly, by the CD player before an analog output is created. The same for creating a digital file like FLAC. Going further, how about all the digital data which is sent hither and yon, copied, and archived.
Computer program publishers are naturally concrned that their works will be copied and distributed, etc. Apparently the concern is that the pirate copies are indeed perfect -- or at least all errors have been detected and corrected. Don't Reed-Solomon techniques do this?
It wouldn't be difficult to do a hash analysis of the files to detect errors in original versus copied files but I've not seen things like that being done.

It is certainly true that the tweeter of any speaker system is the most delicate and prone to failure. Regardless of rating like "100 watts program" the units are only capable of absorbing 3 to 5 watts continuous or so without failing. The windings are made up of wires about the diameter of human hair.
The reason for using thing wire and lightweight diaphragms is simply mass. High frequency movement require high acceleration. And F=MA. The windings and magnet are the motor proving the F. If you want high A you must have low M (thin windings).
What has happened with some regularity is that a posting member will say his tweeters are burned out and suspects the crossover network Then it come out the units werer just purchased second hand. In my view prbably the original owner recognized he had a problem and sold them off. I bought some Quartets like that. Happily it was an easy repair and not worth arguing about. They were otherwise minty.

Matt. Welcome.
I can't answer your questions about specific amps.
Let me say that I had some enlightening experiences with good performing home systems in large venues such as a cafeteria and outdoors. They are just enemic at best. It may be difficult to believe until you try it yourself.
It is correct that multiple K-Horns and LaScalas with 100 watts or more can do the job in a dance hall Forte, though, just can't do the job with one home amp in my view. So please be realistic.

See https://en.wikipedia.org/wiki/Alphonse_and_Gaston
and the link therein to Goofy Gophers.
It was a funny cartoon where the dog is approaching rapidly and the gophers are debating which should go down the hole first. At the end they agree to hold hands and both jump down in together, and just in the nick of time!

In my view that is a square (or oblong) magnet which is made from a slurry of ferrite. The slurry is called "mud" and therefore it is an M. It looks like there may be Z brackets but I don't know how that affects a suffix. ("q, s"???)

The 63/37 has the lowest melting point. Consistent with what good Marvel said, it has no slush stage and IIUC that slush is what causes the dreaded cold solder joint.

Is that correct that the Forte II had a rubber surround? I don't recall that on mine. I had to sell them, which after all was not really necessary.
