Introducing SPL Chart

[DaveK]

you guys must have all missed the thread where I was talking about using W10s as dedicated tops....

Saw it. I suspect Harley did, too, and that's what got us thinking about the subject. I can't remember if you included the comparison chart. If you did, I apologize for the duplication.

I'm fairly sure I did, but I dont remember. I believe the general consensus was that the DR280 > W10 as a top, with similar box size. The w10 takes a lot more eq to act as a top as well.

The DR should be a better box since it has a longer horn. J112 and W10 are a much closer comparison since they have a similar horn length.

Can you add a THT Lab15 18" vs 24" chart? The Lab 15 is in the plans but no chart.

Thanks
Dan

Hi Dan,

I've had a good look round but I can't find a copy of the chart to sample.

Okay, thanks for trying.

There is no chart for a LAB 15 in a 24" THT because it's not a recommended use. LAB 15 is only specified for 18-20" widths.

Bill,

Is there a chart for the THT Lab 15 18"? It is not in my plans nor can I find it anywhere. I am not trying to , Just want to see what I am dealing with since I have a couple Lab 15s on order.

Thanks,
Dan

It's similar to the 24" but with the lower corner frequency at 28Hz instead of 25Hz. In a 30" width the Fc is at 22Hz.

Thanks for the reply Bill. What driver loaded 24" are you referring to? I found charts on the Lab 12 and Tempest 15, from the charts I am assuming it is the Admire 15

In a 30" width the Fc is at 22Hz.

I am not sure what this means. Can anyone help me understand this? Thanks

Anybody?

[Bill Fitzmaurice]

The corner frequency is just what the term implies, the frequency where response falls off and the chart trace turns a corner.

Chris, could you please add the 3012LF T30 in 16", 27", and 30" widths? They're all in the SPL Charts section.

Sure:

Code: Select all

[spl]T30W16D3012LF,T30W27D3012LF,T30W27D3012LFX2,T30W30D3012LF&dbmin=80&dbmax=110&fmax=200[/spl]

Code: Select all

[spl]T30W16D3012LF,T30W16D2010& dbmin=80&dbmax=110&fmax=200&dbmark=89.5,92&fmark=35,50[/spl]

Checked Bill's charts and the 2010 does provide a 2.5dB advantage between 35 and 55 Hz.
