    Horn length extension on Othorns?

    Those D18's have always been one of my favorite looking designs. And StainlessSteve seem to explain it best already from my understanding.

    Yes but these Skhorns are most likely my go to option.

    For me I am building for two different setups. One is for outdoors . I dont mind the size so long as I can afford the drivers.(Maul) So yes a single fold would work but so would many other deigns. Regards to my living room that design is more constrained. So single Skhorn may work but may not just not 100% sure yet. Othorn would almost fit also but I like the extension of this Skhorn design. The BC designs have some extra gain due to their size and boundary loading/gain. I have always like FLH's but cant always fit them. So for me a pair of Skhorn's could work just fine for my outdoor setup. And indoors there are many designs that could work. And if needed down the road I could always drag the living room setup out for extra SPL.

    I dont look at stuff like this because I am using it to its max in a HT setting. I use this stuff in order to have more spl but at lower excursions. SO if I wanted to have a large ported cabinet I could do the same. Probably smaller volume but at also a higher distortion. This may not bother some but it does me. I could also just use a large Xmax driver in a ported cabinet and be happy but my experience has shown me that I prefer pro audio drivers from what I have experienced for ULF. For the pair of 18NW100's you only need about 1000watts to max them out. 118db roughly at 18hz. BUT for me and wanting the lower tune for my singles I do prefer the 18DS115. It doesnt have as much max SPL but it does look better for the lower tune in the volume thats available. So here is the 18PB Z verse the 18DS115, one vent hitting Xmax for both. And the below picture is with about 300watts for the PBZ and 2300 watts for the DS115. But for me these are still a great option for size and low end. And since I will have a pair of DIY SH's eventually above them I think these are great choices. I do like a bit of overkill also. BUT I do like looking at this sort of thing also because I do eventually want to build something like a pair of BC218's.(outdoors) So for now these should hold me over. @Ricci did you get a chance to test the 21DS115? I ask because I wonder if the large coil simulation needs to be used at all when simulating this driver. I would think not as BC seem to be always good with lower inductance drivers. I am moons away from building the single driver version of this horn design. I will be building the normal dual Skhorn with SW152's. So I am mainly wondering from a educational standpoint regarding simulations. And if I can manage to fit the single driver version in my living room I am liking the 18IPALS the most.

    Depending on what your doing two cabs could be better overall for bass distribution. For me the IPAL's are not worth double the cost of the SW152. They give I believe about 2db here and there more output. If you want to maximise SPL per volume then the IPAL's are worth it. BUT we all have different criteria to work with. Some have more budget than room. And some vice versa. BUT now that I have re-simulated the Skhorn (final sim page updated)with 18PZB, 18NW100, 18DS115 and 18IPAL I have to say the NW100 looks better than the PZB for single vent options. And if wanting more than I would go with the 18DS115. I am very interested in doing a single version for my living room if I can fit it in. I would get the 18NW100 myself simply because I had a need for them for another build. I looked at building a large ported cabinet for the living room using the NW100 and down the road upgrading to 18IPALS. But its always hard to upgrade and spend the money when money comes so slowly. PLUS I think I would be quite happy with single version Skhorns in my living room. Just need to finish up some other projects and then build them.

    Here ya go. This is 1watt into 4ohms and 32hz tune.

    I would buy the PZB100 if budget is tight. It looks good in this design for sure.

    No they are not out yet. Probably going to be a while until they are out. Ricci is always busy with a 1000 things. BUT he did say you could just cut the design down the middle and have a single version. SO I have been simulating that and trying to decide between that design and the large ported.

    For me the best value is the 21SW152 drivers. If you can get those cheap then there ya go. I have based all my opinions on Hornresp simulations. I tend to simulate a LOT to hopefully one day build something. I will be building my own Skhorn in Aug/Sept using the 21SW152's. Probably have to wait until Xmas to have the SP6000 amp to power the sub though. For BC options I would have to say these are the best option from best budget to the ultimate option. 18TBW100 18NW100 18SW115 21SW150 21DS115 21SW152 21IPAL If I had 21IPAL money I would see if I could get a pair of 5100's. But thats me. The other option would be to get in touch with Funk and ask if he can make some more powerful (Bl) custom drivers. I asked about this before and he did say it was possible for a good price. I looked at trying to find a 5100 equivalent and it looked like Funk could build me one for around $1000 or less. That is less than a 21IPAL and less than the 5100. Lots of options though.If you have something specific I will simulate it and show you the comparison to the SW152 if needed.

    The 18PZB100 doesnt look bad at all in the Skhorn. It rolls off earlier than the 21SW152 but only a few hz. But is very flat similar to the 21SW152. The 21/18TSAD and 18GUJ are all very peaky. I dont think they look that good but I guess could be EQ'd to suit. Still wish the 5100 was available. These drivers look good also. FP 18HW1070 Beyma 18SW1600Nd BC 18TBW100 looks ok also. Rolls off a bit earlier but not a LOT different then the PZB. I have been simulating almost every driver for this design. I looked at trying to build a single driver version also for my living room. Tried to see if I could get the design to not get too big but perform similar to the 21DS115 in 350l 15hz.

    B&C 21DS115

    Does it really need that much space. I remember looking at doing 15cuft for 15hz and around 10/11cuft for 20hz. So 20cuft seems like that is more than is needed going by memory. Although I was looking at the SW152. DS115 does simulate very similar though. I am away for work so I cant look at comparisons on simulations to help sorry.

    Big thanks to SME for fixing the images

    Awesome to hear. Thanks SME.

    Hopefully your single version takes advantage of being a single driver version and perhaps a slightly larger version also.

    You would have some port chuffing with the 19hz tune and using the 21's. BUT since the 18's dont move as much air as the 21's you will most likely be fine with 19hz tune and using the 18's. Thats what I was saying in my earlier post.
