  1. 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.
  2. 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.
  3. Ricci's Skhorn Subwoofer & Files

    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.
  4. 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.
  5. 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
  6. 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.
  7. 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.
  8. 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+.
  9. 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?
  10. Ricci's Skhorn Subwoofer & Files

    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?
  11. 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.
  12. B&C 21DS115

    SO the first model is the 21DS115 vs SW152. It some areas the DS looks better. I pushed both to about 20mm but I was just doing a quick sim from what I had. Then I selected the lossey Le in Wizard and you can see the DS in black verse the Le in red. Not a huge difference but enough to make sure you simulate it is all. For me the DS115's are about the same price as the 18IPAL's. So thats why the DS's are very interesting. I am not ready to buy any more speakers for now since I still have to finish my Skhorn first. BUT I do want another pair of horns to build come January. I just keep forcing myself to make a reason to get the IPAL's.
  13. Questions about othorn,keystone, Xoc1 th18, DSL118 and others

    For me the option is the Alpine SWS 15 or 18IPAL. Amp wise I dont have an issue there because most amps can handle 2ohms. BUT when I find something I will build using the 18IPAL I am looking at just using a SP 4000 amp. PLUS I will be buying one for my Skhorn build anyways. Look to see real world how the IPAL does in the Xoc1 TH118. I dont have the plans on Toms design but dont mind building the clone.
  14. Questions about othorn,keystone, Xoc1 th18, DSL118 and others

    Will be interesting to see what your results are. I do like the IPAL but havent been able to make a design that warrants the extra cost yet.
  15. Questions about othorn,keystone, Xoc1 th18, DSL118 and others

    Wow did they really use the 18ID driver? Not a fan of that design. I do like the 18IPAL. I just need to come up with a design that can hit crazy SPL and go low enough for me to warrant buying them. 21's are only 100 more roughly.(SW152)
