JBL L 250 A New Addition To My System
- Thread starter 4-2-7
- Start date
Both are gutted now except one Xover. And one has the finish striped off, what minimal finish it had. I didn't bring any finishing materials home from work. I could be done by monday if I had. maybe I'll get some thing at a store:scratch2:

Agreed
I beg to differ. Did you know that JBL offered kits to upgrade L-250's to 250 Ti's? The cabinets with a few minor differences are the same. Also, I can guarantee you that if I did such a conversion I'd keep the L-250 parts. Also, I'd leave the stock crossovers alone and instead build new N250Ti networks. It would be a Frankenstein if you substituted wrong parts, like a different woofer.
We all see this a lot.
Not this chicken, but I wouldn't be afraid to build a new network including biased style based on the published schematics and following key elements like matching the DCR on inductors.
Sage advice. The L-250 is pretty outstanding on its own.
A factory kit is whole different thing than uneducated window shopping on digikey or mouser and revoicing speakers by untrained ears. A mistake I have done recently myself following the beehive mind.
I am not in general against modding, tweaking and such. In this particular case with Dan and his 250s you bet your sweet bacon I am.

My heart stopped there for a second.
The speaker foam came today, now thats fast. This will speed this up a bit:thmbsp:

Did you match the caps to original ESR specs? What lab equipment did you use? PM me your CV Mr. :grumpy:
I live three miles from Mouser and the founder is a customer of mine so he let me raid the surplus and closeout bins. :yes:

Wow. You have some awesome and VIP customers. No wonder that garage rocks!
First part is fact, second part is pure fiction (I raided Madisound's website).
Just saying I would refrain from using any sealant type of finishes. And stain if any I would think minimal. Rather just a nice rub in oil finish. I know speakers are not antiques, but I have seen many valuable antique furniture values vastly diminished by people who think they want an antique to look new. Original finishes are highly valued, even with their issues. Many collectors will simply not purchase something that has been refinished they prefer the patina of an original finish.
Hi Ken
Yes I know Im a furniture finisher by trade the past 35 years.
I washed off what oil was still left because they are extremely dry and faded on some sides. I am not planning on going over kill on these sanding. This is the mistake some make trying to get the wood perfect. They make the wood look to new. I could do that and then bleach the wood and come back to a darker finnish again
I make bran new custom furniture look like antiques. Then I also get the ones that have something beat up and they want it looking new again.
I think my direction on these will be Restoration. So that means I'll make them look like well maintained original and finish them by hand.

When I had a pair i just used howards wax and feed on them - (there is an old thread of mine when I redid a pair, including the surrounds) I also sanded the barrier strips in back lightly to get the oxidation off and it improved the sound - the speakers are amazing in a big room and sound like live music - to me they weren't as good sitting between them soundstage listening as other speakers I've had -( I couldnt sit in back far enough in the room i used them in, so that might be a reason)
Ok I have the speakers gutted,striped and sanded. I will be bringing dye stain and a wipe on finish home from work tonight.
I decided on doing it this way opposed to bring them to work. For one it's easier and it might be helpful to other DIY that don't have access to a finishing shop.

I once heard a L250 vs. Kappa 9 shootout.
I say distress 'em and show how tough JBL can take a beating and be trendy at the same time
As I think I've said before, I've also compared them, and I much preferred the JBLs, but to each his own.
Oh, those are going to be so nice! Have you decided how to remedy the chipped veneer? Are you going to put the speakers on some sort of feet or risers?
They require careful set up in general. I've heard them sound good with large and small amps both tube and solid state. They are fairly efficient but would benefit from the control and damping of a large solid state amp. Purists don't like equalizers but in most rooms I've found that they (at least the Ti version) benefit tremendously from some low frequency cut in the 60 - 120hz region. They are such a neutral speaker that any bad relationship between them and the room in the bass region makes them sound dull and lifeless.
