Mesa Boogie Walkabout Mega-thread Part 10

The difference between the original Deltalite from the earlier Scout cabs (with the vent on the front dust cap) and the Deltalite II is pretty big! Can’t say for sure that there is any difference between the Mesa OEM speaker and a stock Deltalite II, but I used a stock one in my old Scout 12 for years and it sounded great!
if it wasn’t for the resonator I think I would be trying to make a clone-a-like of the cab with a Deltalite II ...
 
Which vent, and where's the dust cap?Thanks.

Well I have the one type in my WA, and the other type in my ext cab, so I'll have to try them one by one side by side to see if I can tell any difference. As I mentioned earlier though, I'm quite new to playing bass and haven't yet done a gig, so I may not easily tell a difference. Or I might notice a difference, but not really know what it is. That's more likely I would imagine.
The biggest difference you should notice is that the new one can handle quite a bit more bass frequency before “farting” like my old Scout cab would do at moderate volume. The new one is a better-rounded bass speaker all around, with less peaky midrange. They honestly might sound good together at low to moderate volumes- it’s all subjective. They are definitely quite different!
 
The original series 1 Deltalite was a step in the right direction but sacrificed low frequency extension for more extended high mid voicing. Once Eminence got some more experience with Neo motor design, they introduced the vented motor which is far superior as well as lighter weight. The reason the series 1 has a screened dust cap is because the motor is not vented and the spider had too much air resistance to work well.
 
This is my damaged driver from the combo

Don't ask me to point out the damage in this light - it's literally a tear in the suspension part (whatever that's called) the size of a small screwdriver blade, and I have carefully pushed it all back together ready for whatever (as yet undiscovered) repair method I employ.

The middle part you can see through on the front is the vented dustcap that is the tell-tale of the original Deltalite design

Thanks.

Well that's good news really - more tonal range?

I've only ever tried them both at the same time once, and it was almost too much.
That was in a church hall with just me and the 3 guys I was practicing with in there.
I knew when I heard the two together though, that I'd made the right choice in buying them.
 
I believe the replacement is not a stock DeltaLite 2512, but a variant. They may have a DeltaLite logo on them, but those can be used with any of the DeltaLite models. The passive radiator tuning works differently than a port does.

It's the info around this page of the thread that prompted me to order the Eminence Neo - particularly posts #411 and #412.

I’ve always been curious about the Scout cabs because they have both a radiator and a port, which seems like it would negate some of the radiator’s action

I just sold my WA.. Mine was stock with the 4Ω speaker.
Its 300 watts sounded very hefty into a larger 610 or 810 cab.

From my experience the WA 300 watts is almost as stout as an SVT head and the original WA is about as close to an all tube amp that you can get without getting an all tube amp.

I compared my old WA to my SVT-CL with both a Berg HT322 and a TL606.
I used one of those Ampeg Selector switches that they used to have at music stores so turn the knob and plug into a different amp; takes 5 seconds.
For clean power, both amps had the exact same SPL (as heard by me).
Very tubey and I didn't have any issues with the low end.
I loved that amp but not enough juice for an ineffecient cabinet, clean, and medium loud.
As mentioned in previous threads, line out to a big power amp does not sound the same.
The resale on the WA's in excellent; same price used 5 years ago as to today ($450ish average used price).

Ironically, the ABM 500 (575 watts at 4 ohms) does get the job done with headroom to spare.
Never would have thought that 275 watts would make that much difference.
