136A cone question

[pioneer]

I pulled the drivers to check serial numbers on my recently purchased L300's . Upon inspection I found these two tiny holes just outside of the dustcaps ( hopefully you can see in the picture if my attachment works). They look like they were used for the wires that attach to the cones but maybe put in the wrong spot? it leads to two questions is their anything I can put on to cover them or should I leave them as is. They do not seem to be growing. Part two I was told that these are the wrong dust caps does that effect the woofers? I did a search on the site but I could not find anything in the archives although I am sure this has been asked before.
Thanks

Here's a pic of my 136 and it does look like your dustcap might be a tad larger.

The distance from the edge of the cap to the first set of concentric rings is
1 1/4 inches also, the two leads are clearly visible.

here it is

Aftermarket recone, looks like

[pioneer]

I was told they were reconed when I bought them and supposedly by an authorized jbl dealer but I am not so sure about that.The back of the cone has W5777108 stamped on it. The leads are not visible on the cones they are covered by the cap and on the one I took the picture of shows two tiny holes were it looks like leads had been planned but not finished.

[edgewound]

Definitely aftermarket recone...I hate the misrepresention.
It's just wrong.

[pioneer]

that's the problem when you deal with long distance and have to trust the seller. although in this case the seller was only a middle man and was passing on what the original owner had told him , they did look like they were reconed in the picture with oversized caps. So they question is leave them alone fix the holes , look for replacement or recone these

Well the number one question is how do they sound??? You know you have after market kits so to recone you end-up with 2235's as the 2231's are long gone. With the after market kits you really don't know what you have. Is the mass ring installed?? Who knows??

They actually sound pretty good. Without hearing another pair I am not sure if I am missing anything. Will an after market cone be bad, although hearing this makes want to recone or replace. Mass rings hmm!!!! good question since I do not know what I am looking for I will have to do some searching.
How much difference does the 2235 make in the sound compared to the original 136a or is this one of those personal preference questions.

Pioneer if you decide to have the 136a reconed and done correctly contact John at Pro Sound, Braintree MA, a JBL Pro shop.

[pioneer]

Hi Majick47
I called Braintree yesterday and they quoted $140 to recone to the 2235. Did you use them? He would let me preorder the cones(which he does not stock) and notify me when they came in and turn them around in two days.I also called a JBL pro dealer up in Stoneham who quoted me $109 which is a good price but is a shlepp to go up there and I do not know the quality of their work. I tried the dealer you mentioned in Hanson but I did not hear back from them yet.

[majick47]

Pioneer Pro Sound Braintree reconed two pairs of 136a for me and both were very well done, the price sounds like what I payed. At this time Pro Sound is refoaming a pair of 116h for my 4301b. Stoneham would be a hike for me also. One pair of 136a had been reconed prior to my purchaseing them by a shop on the North Shore, can't remember if it was in Stoneham, the reconeing was very poorly done. I havn't done buisness with the shop in Hanson so I can't give you any recommendation re their workmanship. I remember calling them once and they said they mostly did work on cinema systems.

[pioneer]

thanks for the reply....I assume you reconed to 2235's did you notice a difference in sound from the original 136a's? not that I have a choice if reconing, unless I can find a used pair of 136a's for sale in good condition

[majick47]

Pioneer my L300 came with 136a woofers with the original cones and they had been refoamed correctly shortly before I purchased them. My L200b with the 136a woofers reconed with 2235a cones sounded the same to me as the L300 136a with original cones. In fact I tried a pair of 2235h woofers in the L300 for a while and still heard no measurable difference. Some members with better hearing and experience may be able to distinguish the different 15" woofers but so far I havn't been able to do so. I'm confident that you will be very happy with the results after you have the 136a reconed with 2235h cones. Like you I want to keep my L300 "original" as possible. If you check the product brochure the recommended available recone for the 136a is the 2235h cone and by this time many L300 will have been reconed with the 2235h.
