    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.

    Ricci's Skhorn Subwoofer & Files

    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.
  8. chrapladm

    Ricci's Skhorn Subwoofer & Files

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

    Ricci's Skhorn Subwoofer & Files

    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.

    Ricci's Skhorn Subwoofer & Files

    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.

    Ricci's Skhorn Subwoofer & Files

    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.
  16. chrapladm

    Ricci's Skhorn Subwoofer & Files

    I would suggest, if you have the room, build the Skhorn. Build some adaptor plates in case you decide to upgrade. PLUS when using the 19hz tune you want have to worry about port noise with the 18's.

    I just happen to have this comparison. That is the 21SW152 max SPL verse the 18LW2400 Max SPL. I can show a 1 watt for the LW2400 if needed. The 2400 does roll off sooner as you can see.

    Which 18" for 3way SPL AND extension

    Thanks Luke. I am curious about the dust cap leaking or making any noise when having to play 15hz tones. Might be something that is not even a worry but I dont know. I do know that I wont ever be pushing these very hard. My floors/walls wont take it. BUT I do plan on getting more of these AE drivers if they are to my liking. I still have to build myself a bass rig again also.
  19. So after many years I am finally going to build my 3way. Things have taken a while but I have finally got a job that will allow me to actually start projects and finish them with in a reasonable time. I have a few projects that will finally be finished so I am planning, budgeting and simulating a lot right now. I have looked at building a SH but will end up just building a 2way SH using a TPL-150, Celestion 0410 mids, and a single 18 below the horn. My designs goals were to have a dual 15 design like JTR's 215RT but costs start to add up. I then looked at just using a single 18". Most of the 18's I looked at are similar in SPL and extension. The next filter for me is price verse quality in sound. I have looked at a lot of BC products because they are by far the best value for me. So, I cant afford to buy all the drivers to have a listen to and then return them. So I am hoping others can comment to help me decide on which may work. In the end I think all will probably work very well. I dont need crazy SPL as I am happy with a moderate setup. I am on suspended floors. I looked at buying a pair of 18's to compare in a side by side comparison. BUT I cant help but wonder about the others. I will have a active setup and be using a QSC PLD 4.3 for L/R. So these are the two 18's I thought about buying first: 18IPAL and Funk 18TSAD-R The 18IPAL will probably cost about half the cost of the 18TSAD. IPAL is peaky but does most things very well and can be used up to 350hz. Thats about as high as I think I will need. TSAD does this also but does look much flatter in comparison. SO the first pic is the TSAD vs TD18H Apollo. 2nd pic is TSAD vs IPAL . 3rd is TD18H vs IPAL. 4th pic is BMS 18 vs TD18H. 5th pic TD18H Apollo vs FP18XL1800. And lastly is the GUJ vs TD18H Apollo just for fun. All these sims are in an enclosure of 250l and 18-19hz tune. I will look at trying to tune for 15hz but that will be a balancing act of smooth response shape and port size per volume of enclosure. So how do you choose which. For budget price the 18TBW100/NW100 even works. BUT I was looking at tying to buy more SPL for ULF double duties. So I started looking at higher excursion models. Most expensive option is the BMS 18 or possibly the TSAD. Would have been nice to have bought Ricci's used BMS 18's. FP18XL1800 and TD are about the same cost. So as I said I looked at buying an IPAL either way to compare against the other 18. I have never heard the TD series of speakers so I dont know what I am missing if anything. Just never heard them to say if thats a good thing or not. And of coarse I also simulated Kyle's 5100 speakers. Always considered those also if they were around.:) And to add to this, I will be using this 3way as a fullrange system. Wont be any room for normal subwoofers. Hence such a low tuning. Luke I know you have used the TD18's as you have also Ricci. Dont know if anyone has compared the TD18 against anything else in a A/B comparo or something similar. Thanks either way guys. Ricci, just noticed this in another forum but should this thread be moved to the speaker design section?

    Replacement AVR / processor

    Happy to see someone else thing about the 700 AV. I will be purchasing one for my AVR. Still have some time before that happens but it is the best deal for me and who doesnt like balanced outputs.:D

    Which 18" for 3way SPL AND extension

    BC speakers I dont have to pay shipping and the rest arent that bad to ship. Under 45-50lbs is ok. Anything heavier is when it gets expensive. I wont be basing my decision off of weight of drivers. If I have to pay a little more for one verse the other that is ok. I am only buying a pair of these drivers not 10.

    Which 18" for 3way SPL AND extension

    This was an old reply from John but he describes the PB18H+. He is saying what the benefits are for having the phase plug verse dustcap.

    Which 18" for 3way SPL AND extension

    I was looking at having a 350hz possibility for the 18. I looked at even using the 21's from BC but wanted to keep the width down a bit.(Although it does work in similar volumes just fine) UH21's would probably be a great option but I cant afford those pair of 21's for my system. TD18H looks to easily reach whatever is needed at the Xo and regarding the phase plug I looked at using the PB version of the TD18H. So leaking would not be a problem. Although, I never knew that could be a problem at all. As I said I have never heard any of the TD line up in person. IPAL was a possibility because the excursion capabilities and very low Le. It is very peaky but I figured I could EQ that flat. BUT this is all knew to me when it comes to using that much EQ on anything like an IPAL speaker. And now that you mentioned your 21's, I did have a look at the 21DS115 . It is cheaper than any of the speakers I mentioned so far. BUT most of these are all within about 2-400 dollars. So I am looking at using the best driver I can. The 18DS115 is actually more expensive than the 21DS115. I have a pair of 21SW152's already that will be used in a Skhorn for outdoors. I will have to wait on my TPL's to come in for another 2 months. Once I get those in I can start building the SH. Then use those underneath until I figure out what to use. I hope to have figured this out before then. Also waiting on a few quotes to see what will cost what. Probably hear back from all parties next week sometime. TSAD and IPAL were my first choice for future purchase to compare. Then I was curious about the TSAD and TD18H/PB+.

    Also glad to see you got a quote you can live with and building it out of great ply. Ricci is it best to ask Skhorn "versions," questions here. And will you be looking at designing a single driver version?

    Ricci's Skhorn Subwoofer & Files

    Wow thats crazy for a delivery charge. My plywood will cost me about $75each at the cheapest place for a B/C sheet each. SO things starting getting expensive when you need multiple sheets. Its also why I havent started my Skhorn yet. Baltic Birch would probably cost me about 200 a sheet. SO ya I tend to build a lot of things also in MDF.
