Introducing SPL Chart

[moo]

Afaik, the OT12's were measured with the 2512. I do have charts for the 3012HO which I need to get sampled.

That would be Brill. The Delta Pro 12 should be similar, - but heavier of course.

Mystery over. The 3012HO chart is now included in the updated plans.
Is your chart for the new phase plugged OT12?

[Chris_Allen]

The existing charts are for the old design but are scheduled to be updated.

any chance you could model a O15tb/wb against a fEARful 15/6?

Do you have a measured chart for the 15/6?

i dont. ill ask around on Talkbass to see if one exists

Maybe not exactly what you're looking for, but I compared the the woofer only sections of both using the exact same 3015LF driver. Outside, ground plane.

Omni has a 3-4 dB advantage at 40-50 Hz, Ff has 3-4 dB advantage at 80-100 Hz.

Omni has a 3-4 dB advantage at 40-50 Hz, Ff has 3-4 dB advantage at 80-100 Hz.

I've built another O15TB to do so some revisions, mainly to the midhorn/tweeter. I'm not getting the nulls at 80-100Hz and 315Hz like you are. I'm also not getting that 50Hz bump, and the LF corner is at 40 Hz. I'm using a 2515 woofer for the testing. In theory the 3015LF should be almost identical, so I'm still puzzled with your result.

I'm assuming no piezos or horn on that J110?

Correct. That chart is the one for driver-only. No tweeters of any type.

Harley, was your point that the W10 has better response than the J110 across the board? Are you thinking of switching?

It''s not for me - I have a client who wants both a W10 monitor for keys and a J110 for upright bass. Was thinking of just one wedge shaped J100 or a W10 to do both jobs, hence the comparison.

For my own personal bass use, I am happy with my J110s in either one, two or three stacks for most my gigs which invariably have FOH so no I would not switch to a W10 for bass. I just need enough sound on stage and that's it. The T39/Dr250 are our FOH system. I am more concerned about what comes out of FOH than on stage and the T39/DR250 deliver excellent quality with heaps of low end if need be.

[DaveK]

Here's an apples-to-apples comparison with a cab about the same size.



That looks like a tie to me. The J112 stacks better and takes a bit more power. The W10 has the flexibility to be used as either a wedge or a top. If I were looking at building a pair of J112's as tops, I'd seriously consider building W10's instead.

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