Reply With QuoteI dont think you will get a vash improvement. You can try something with a whizzer cone, or even adding a tweeter. I put a speaker with a whizzer cone in an A100 and it doesnt seem any brighter.
Has anyone used different or more modern internal speakers for any of the spinet models? The stock unit in my L- series is a little too low end for my taste and I want to get something that is more mid to high mid. I've considered lining out but I would like to have the option of still being able to use the internal speakers. Any thoughts or suggestions?

I have a hole in my M3 where someone installed an ignition switch (likely a church)so a tweeter may go in the hole with a crossover inside the organ
1956 M3, 130 custom leslie, 51 Leslie, 860 Leslie with Preamp, S08 Yamaha and K2000S, Young Chang 85 key spinet and Korg SV-1 73less Hammonds, downsized they found a good home
When re-designing the works in the stationary channel of a Leslie 415, our engineer used a 12" bass unit, 2 x 8" mid range and a horn tweeter. All from JBL or Celestion. With a little fettling to balance them out and tame the tweeter a little, it was a massive change. Driver from the stock amps in the leslie. No reason why something similar wouldn't work in a spinet, and it would be easier to squeeze in!
But just how much in the way of highs do you expect from a stock L?
It's not what you play. It's not how you play. It's the fact that you're playing that counts.

The L-100 series amp is looking for 8 ohms. You have a few options. An 8 ohm speaker like the Eminence Beta 12 LTA (12" woofer with wizzer cone) goes up to about 8khz. You could use just one and cover the other hole. The efficiency is close to the original speakers. The Eminence Delta 12B is a 16 ohm driver and you could use two of those wired exactly the same as what is in there now and get a boost in the high end. I think tonewheel general uses these as a leslie replacement. The other option would be the Jensen P12 or C12 clone from Weber Speakers or the New Jensen company. How do I know... well I have two L-122's and I have played with the eminence Beta 12 LTA. With 11-18 watts the Hammond amp is not going to make you go deaf.Originally Posted by the demiurge
Thanks
The L-100 amplifier has integrated low-pass filtering. If you truly want a night and day difference, you'll have to do a few electrical modifications first. You'll find that most speakers you hook up will sound weak in the treble end, otherwise.

Interestingly, an "old timer" told me that back in the sixties they used to replace the spinet speakers with guitar speakers.... supposedly they got a lot more volume out of it. I reckon that's an old fisherman's tale though.

And I touched a 1958 M3 once.
Actually, replacing those speakers with JBL or a Celestion Blue, both rated at 102 dB per watt at 1m would definitely improve the volume and top end a little. Still not going to stun the grandkids, though! Tapping into the speaker cables for an external, solid state amp (which is basically what the reverb amp does) should be pretty easy, then run that to a high efficiency self-powered box like the Mackie SRM450 and you've got all the volume and top end you could use. Just run thru a direct box with a 20dB pad engaged.
Hmm... Food for thought. Thanks all.
