Looking for an operable speaker that goes behind the dash, for my '58 sedan. Early Lark may be the same.

TIA. :)

Wouldn't any 4x6 4ohm modern speaker work, and produce greater fidelity?

I have no idea.. [:I] Though a modern one may be better to have.

Absolutely.As long as it can fit and you can run wires to it,it's not an issue.Just don't let any SDC judges know!![:0]

Have you tried Stude Intl? I got a speaker for a Lark from them.

Check what you can scavenge off those junked Lincolns and Mud Turtles; should all be 4ohm, with mid-range and center tweeters; better than original.

You need a 10 OHM speaker, we went around on this here before, some thought it did not matter, but the electronics pros said; NO, it damages the output transformer I think it is called, power supply whatever with higher volumes and longer term use. [:0]

For heavens sake, get a new speaker! Any old speaker will have the paper cone dried out and just ready to tear. If you have the old speaker, check the ohm value printed on the rear of the magnet. If no old one, go to the trusty manual. New speaker, same ohms.

Most of the Studebaker car radio's and speakers systems we are dealing with are monophonic {not stereo, not 2 channel} with 10 ohm. output {impedance} and less than 10 watts peak power output. I don't know the exact figures. Like said previously, it is best to match the radio's output impedance to an equal speakers input impedance. If the speaker impedance is less than that of the radio's output transformer, or output transistor, whatever the configuration may be, it is said to be a mis - match. This theoretically, and does, allow the radio's output circuit to be operated under stressful conditions. Temperatures within the components of the output circuit will increase beyond their tolerable limits, thus contributing to premature failure. Sooner or later. Just when? I don't know. If the speaker impedance is more than the output of the radio it should not harm the radio. It probably will not sound proper An impedance match supposedly will allow for a better quality of sound reproduction, although wattage ratings, {power output in watts "W" should be considered also. In my opinion, if you use an 8 ohm speaker in place of a 10, I wouldn't worry at all. The radio will probably not know the difference. A standard Studebaker car radio speaker was probably under 12 watts power handling capacity. You don't need no steenking 90 watt ball buster speaker. Your stock radio wouldn't be able to move that speaker cone enough to create an adequate amount of quality sound reproduction. Just get a cheap low power handling capacity speaker. The right physical size should be available with 8 ohms at less than 20 Watts capacity. If you want 2 speakers, get two 8 or 10 ohms's and a fader control. "If you don't want a fader control, two 8 or 10ohm speakers wired in series across your power out will be 16 to 20 ohms impedance. Wont hurt a thing. I don't know what it will sound like. Parallel speaker combinations sum up differently. Two 8 ohm speakers in parallel become 4 ohm as a combo. Two 4 ohm become 2 ohm as a parallel combo, Two 10's become 5 ohm as a parallel combo. There are parallel - series combinations also but I don't want to complicate any further than I may have allready. By the way, make sure your speaker or speakers are phased properly. -to ground and + to radio spkr. output. They work better when in phase. You wouldn't hook your starter up backwards would you? jimmijim

Since we are on the subject of speakers, my original 63 lark am radio works, but the sound falters. one minute it is fine, then, unexplicably, the sound drops about 2/3 in volume, then it comes back. At first, I thought it was a short, but why would there still be sound if it were shorting out? Wouldn't it cut out completely?

If you feel that your antenna is ok and they usually are,check the wires to the speaker firstly. Substitute another speaker temporarily. 8 to 10 ohm. One from your stereo will work. If symptons persist you may have a radio problem. jimmijim

The ohms of the speaker should be matched to the radio. Ir you install an aftermarket radio it should be marked as to what speaker to use. The old Western auto may have what you need NT

If only one of your ears is plugging up, the sound won't cut out completely. You can troubleshoot this by putting your finger in one ear at a time and compare the sound volume.

As another possibility, if the radio audio output is a "push pull" circuit amplifier then the loss of one side of that circuit will give half power out. There may be an "intermmittent open" problem (cracked circuit board, bad connection, etc) that might account for the symptom of reduced output. In real life: A "short" generally causes some permanent circuit damage and those aren't as likely to happen as an "open".

I talked with a radio rebuilder last year at the Ozark Empire swap meet in Springfield, Mo about the intermittant a m reception on my modern radio when the f m works great. He said that the
a m is much more ground sensitive. You must have a good antenna ground for the a m to work correctly. I polished the underside of the fender where the antenna is mounted and it works much better on a m but still needs some work. I plan to add a ground wire to the antenna base.

You have the the most common problem with the Delco Transistor Radios, usually also; you can move the volume knob and it makes scratchy sounds, and works good in only certain spots on the volume control.

When that happens it is a bad Volume Control, sometime if you buy some of that canned Nitrogen in spray cans you can remove the knobs and CLEAN it, and maybe delay needing a new, hard to find replacement.

You also could try putting a better ground (wire) on from the case to the Dash chassis instead of depending on the mounting brackets for ground, that may help.

I have some CRC Brand Contact Cleaner 2000, it is a liquid electrical contact cleaner, I will be trying that at some point, on my Delco AM/FM volume control.

Update: Neil; It does dry in in about 1 sec. ,it's highly evaporative.

Thanks! I hadn't even thought of the volume knob, I am going to go ahead and try both of your suggestions and see if that clears things up.

Tutone! If you spray any liquid into the radio be sure to give it time to dry out before putting power to it. I worked at a radio station in the 70's. We used a spray called a "POT CLEANER" to keep the static down in the control board. The brand name was L.P.S. I don't know if it is still around. We were cautioned to let it dry completely before re starting. I have been told starting fluid will work also but have never tried it. NT

Once the carbon tracks of the volume control pot are cracked the best thing to do is replace the volume control pot.The cleaners and sprays are only a short term fix. Any competent radio technician can replace these volume control pots.

It appears that Richmond would be a good one to use for re-coning your speakers, probably $55.00 ea. professionally rebuilt. :)

However this Simply Speakers, does not have one single Auto Speaker (Oval) listed, and NO 10 OHM. :(

They do have some nice speaker and speaker grill CLOTH though, that should help protect your speaker cone paper from sun damage.

There are about 4 ==== nos 10 ohm delco 4 x10's on e-bay right now. Not going to bring anything near 55 $.

Bad as I hate to deal with eBay, I just bought a new 4x10 with 10 OHMS for $25.

Thanks everyone for their help.

Sorry, guys, I guess I missed all of the posts between my first one and Studeriche's I will still try his idea, but I totally missed the one about antenna ground! My antenna, it just so happens, is a bit loose, and needs tightened...this may be the problem after all!

Matt, sorry for hijacking your thread, it is good to hear that you got yourself a speaker.

Why do you hate dealing with ebay? I think I have only had one bad experience in all of the 8-9 years I have dealt with them.

I'm just not a big fan of ebay. My last purchase was a $40.00 shifter stick for a Hurst. Long story short, I ended up with a nice, empty, $40.00 box. Oh well... [V]

Definetly not the usual type of e-bay transaction. Freakish. I have had all positive results but 1. I sometimes check feedback before bidding. Was the package sealed? Did you follow up with the seller? jimmijim

While on the subject of speakers, the Avanti Parts manual just shows a picture of the front speaker. My 63 has a front and back with fader control and the parts manual list them as different parts nos. Are they both the same size? Are they 4" X 10"? As I restore my Avanti I think I will replace both speakers to work with AM radio and then put a remote control stereo with CD changer in the trunk for modern sound.

Matt; be sure to let us know what if any contortions you went through to get that 4X10 in. Speaker you bought in there! [^]

If I remember right, the original was closer to 5X7 or 6X9in.

You're right Rich. Looking closer, the 4x10 won't bolt up. But I think I can make an adapter plate easily enough. :)
