X = Cones
Y = Sundaes
X + Y = 182 --- Y = 182 - X
0.90 * X +1.65 * y = 226,05
0,90 * X + 1,65 ( 182 - X) = 226,05
0.90 * X + 1,65 * 182 - 1.65 X = 226.05
300.3 - 226,05 = 1,65 x - 0,9 x = 0,75 X
74,25 / 0,75 = X
X = 99
y = 83

SOURCE: speaker repair

Contact MMats Pro Audio at 561-842-0600. They can re-cone it for you, or sell you the re-cone kit. If that does not work for you, contact MWA Speaker Parts in Tuscon - 520-647-7193. They can sell you a re-cone kit, or they can direct you to a speaker repair center near you. A third option would be to contact Sundown Audio in Troutman, NC. They may be able to re-cone it for you.

SOURCE: sub with stuck cone

Search for a RE-CONE Kit, Not sure if they make them. Only ship to JL if you are under warranty & even than it's a hit & miss. Good Luck!

Rear axle replace

screw 1 of the cone pieces(that fit bearings)tapered section towards centre of axle(about 3/4 inch), then slip 1 bearing case on axle from other end with bearing side facing centre. Then insert axle into hub and put bearing on other end(bearings facing middle)then cone.
**NOTE** Put small amount of bearing grease inside hub for bearings. Doesn't have to be bicycle grease- I use auto grease as you get 10times as much for same price.
Then adjust cones by hand untill there isn't any slack and axle centered.Then screw on thin nut(both ends), it acts as lock nut for cones.To tighten correctly you need a skinny spanner to hold cone while you tighten the skinny nut. Spanners from bike shop only cost about $2. Can adjust without a narrow head spanner by leaving a bit of slack when doing up cones and hopefully lock effect between cone/nut grabs before cones are over tight(a bit of messing around without a narrow spanner).
There shouldn't be any slack between axle/cones and wheel, wheel should spin freely.
Put wheel on bike then a washer(if you have any)outside frame, then larger wheel nuts.
Hopefully all your pieces have been used. HAPPY RIDING

you should just buy a replacement speaker and install it, replaceing the cone would not be cost effective, in fact you could buy a better speaker and get better bass out of the sytem, try they are in Cleveland and sell many great speakers in all sizes.

I have signature classics 12 cup coffee maker with timer model# xq626-wt svc code 2764 i can not find a filter for it According to this link and others, we need to use a #4 filter. I placed my old #2 cone filter in this machine (I just bought it tonight) and it is short about one the next step up would be a #4. The bottem of the basket that comes out, would lead one to believe it is a cone shape cone. You can also opt for a perminent gold cone filter. But, use the paper one first to be sure of the size. I am getting #4 tomorrow and test this machine out. It has mixed reviews on line. Coffee Maker is the brand name and I only see it sold at Home Depot from my on line searches. Good luck....blkqueentech at yahoo dot com

University theater sold 444 tickets for a play. Tickets cost $20 per adult and $15 per senior citizen. If total receipts were $7345 how many senior citizen tickets were sold?

Let A = number of adult tickets and S = number of senior tickets.
The total number of tickets is 444. This equals A + S.
444 = A + S
Total receipts were $7345. This can be represented as:
7345 = A*20 + S*15
Solve for A in first equation.
A = 444 - S
Substitute this into the 2nd equation for A
7345 = (444 - S)*20 + S*15
Solve for S
7345 = 8880 - 20*S + 15*S
7345 = 8880 - 5*S
-1535 = -5*S
307 = S

Therefore there were 307 senior tickets sold.
The number of adult tickets would be 444-307 = 137

It cuts out at high rpm but the plug is fine.

Pull the spark plug. If the porcelain cone is whitish then change the main jet to a higher number i.e.. 178 original main jet changes to a 180 or a 182 if needed.

If the porcelain cone is blackish or sooty then change to a lower number i. e. 178 down to a 175 or 172.

Ja switched capacitor C8, based on my research of other users, but got no result.

Please help me!
