Theoretically you are correct but I think you will prefer them without delay. (Also check if you prefer the delay for the tops on 10ms instead of the 5,9ms)

okay cool i'll set up the third amp and ss15 and have a listen. Stacking configuration suggestions for outdoors and the 5 speakers (2 TH-18, 1 ss15, 2 JRX 125)?
I know the horns have better dispersion on their sides, I just have them stacked this way because there is no room to lie them down inside the small room.

I just finished reading all threads posts in here, I am hooked.. I currently have 4 SS15s so... what would 2 th18s do different, I definitely do not have the money nor the space for 4 of these monsters... I am looking for more SPL, I have 4 EV ZX5s, I have 2 QSC Plx 2402s and a yamaha p7000 ... I DJ so most of the time I only use 2 of the ss15s, but there was 1 time where the 4 ss15 were not enough for the room... it could have been my configuration, but they were not enough for that room... Thanks in advance
Where the SS15s are loud from ~50Hz on up, the TH18s are loud from 35Hz on up. So, it will depend on what style of music you play to deem the TH18 beneficial to you. With the B&C 18SW115 driver, the TH18 is about as loud as 2 to 2.5 SS15s. The TH18 weighs 3 times as much (160lbs vs. 50lbs - it's bigger, uses thicker wood: 3/4" vs. 1/2" and far more bracing) and depending on the driver, can take up to 3 times as much power (1700W vs. 500W). As far as packing more SPL in less space, the TH18 is where it's at (vs. the SS15). One TH18 costs just about as much as 2 SS15s (depending on driver and accessories), but again, will be louder than those 2 SS15s.

Aaaaaaaand B&C's neo products finally went UP!18SW115 went from $449 to $582
Glad I ordered mine when I did! Need to see what wholesale went up to... I wanted to order a couple more pairs
*just looked it up, now wholesale went up 92 very sad

Nice overall explanation... Exactly what I was looking for.. I see that many speakers have gone up in price... can anyone explain why other than forums like this?? Meaning of course, more people buying more speakers for use on their boxes..

One would have to measure the two subs side by side to get an accurate comparison.
Since internally and externally the Xoc1’s TH-18 is very similar to the DSL TH-118 (which presently uses the BC18SW115-4, previously the 18 Sound NLW9600-4) using the same speaker they should be very close in level, but Danley’s sensitivity graphs seem to be higher than Hornresp predicts.
There are a some comparative measurements in sub shootouts and Josh Ricci’s Data Bass website that also seem to indicate the DSL sub measurements may be high.
I have had discussions with Ivan Beaver and Tom Danley of DSL regarding the disparities, but short of some side by side measurements (which Ivan has been too busy to do) of DSL subs compared to other manufacturer’s subs that have published charts, the issue remains unresolved.

The Danley TH118 SPL chart is for 28.3 V @ 10Metres with a 4 Ohm Driver. The equivalent measurement would be 40V @ 10 metres for a 8 Ohm TH18.
Even so the TH18 equivalent sim seems way off Danleys published TH118 - figures being between 3 to 5 dB lower.
Of course the only build that we have so far is mRgSr's, and no real measurement data to go on yet
Thanks for the positive comments, but I will feel a bit easier about them, when we have some real world data to base them on!

Danley's 'sensitivity' specs come from a peak at 90Hz and at 138Hz (higher than my crossover frequency). But, yes, from 20-100Hz, the Danley TH-118 provides more output......and costs 4-5 times as much
As far as my eyes can see:
.......... 30Hz.... 35Hz.... 40Hz.... 45Hz.... 50Hz..... .60Hz.... 70Hz..... .80Hz..... .90Hz.... 100Hz
Danley 101dB .. 104dB .. 105dB .. 106dB .. 107.5dB.. 108dB ..108.5dB .. 108.5dB .. 109dB .. 107.5dB
Xoc1 ...93.5dB . 99dB .. 102.5dB. 103.5dB .103.5dB ..103dB ..103.5dB .. 104.5dB .. 106dB .. 106dB
Yes, my Danley # at 90Hz reads 109dB - not 108dB like on his spec sheet. Again, this is what my eyes see on his response chart. His plot, 114dB @ 138Hz, looks it - so, I feel that what I see is accurate enough (within 1dB).
Hope this helps a little - no more toggling between tabs/pages/jpegs

Yeah...uhh..i dont have any test equipment. anyone in the NYC area who does and wants to test these be my guest!! just contact me!
