    Mouth could be facing front of couch? Or back back I guess if the wall behind couch has some distance. I was thinking it would be a great way to add a large horn sub. Basically take no room up, and be near field. win win win?

     

    Improper placement will cause a null in frequency response, if possible fire it into a boundary for best results.

     

    Near field placement is not a great choice in my experience using horn loaded subs.

    Wonder what a horn sub built like a 1-2' tall platform like. That a couch could sit on. Or under the couch. If the couch legs were raised a foot. 

     

    As long as the horn mouth is between 18"- 2 1/2 feet from a boundary ( depending on the crossover point) to avoid a null it would work fine.

    I'm good with having something larger than the lil wrecker since it's going in a pretty good size room...14.5 x 35 or so. I don't play at ear bleeding levels but I would imagine I get over 100db on occasion.  Tinnitus doesn't allow for too much more volume, but, I do want some solid bass along with the Belles. I figure it will have to be something like the THT with the 10" woofer.  Years ago back in my car audio days, Kicker (Stillwater Designs) had a box design that used 4 of their C-6.5" woofers that was called "suitcase full of boom". It was very impressive in the hatch of my 93 Cobra for sure but you had the transfer function of the hatchback to help its LF extension. Maybe I'm more from the school of "there's no replacement for displacement". :D

     

    Subs in a hatchback with the rear seat down works just like a horn along with the added cabin gain can work very well.

     

    A 10" driver is really not recommended in the THT though it will work,  better if used in the Table Tuba design and the recommended driver is very reasonable in fact less expensive than the little 6.5" driver in the little tapped horn mentioned earlier with far greater output.


  4. The only advantage to that tapped horn is its small size. Probably fine in a smaller room at lower outputs.

     

    If you do decide to build one don't include the padding on the bends, it serves no purpose.

     

    Max output would be similar to 1 watt through the Belles but it would be struggling by that point.


  5. The Tuba 18 is not worth adding as it really does not dig much lower than your mains.

     

    I suggest a 10" or better Table Tuba or THT in the corner and not the THTLP unless you plan on laying it down firing it into a corner, sloped ceilings are not the best place for the horn to exit.

    No? I'd love to hear your theory about how BFM always manages to find these threads, in which you also participate, without an active account or forum presence. I mean, he had to create a new account just to post his weak legal threat, so clearly he's not haunting the subwoofer section on a daily basis and had to be tipped off by ... someone.

     

    Bill is a member of many forums, he probably reads the forum here.

     

    Maybe somebody said something, i don't know but many forum members have done business with him that i know of and could be many more but to blame me is just wrong.

     

    You want to make an *** out of yourself that's fine but leave me out of it.

    All you really had to do Bill, and Jason by proxy, was come here and remind folk that you've put a ton of blood, sweat, and tears into your designs and all it takes is $15-30 dollars to purchase a plan and support your continued efforts. But to come in here swinging dick about flimsy copyright claims for assumed violations, and not actually provable? Bad form.

     

    Sad assumption, i come here to help and learn.

     

    I recommend Bill's products because they work just as i recommend Klipsch where i can.

    He doesn't list a thtlp... I've never heard it reffered to except on this forum. He does have a t45 but it doesn't look the same.

    On the lower part of the THT page it lists the Tuba low profile version hence the THTLP and there are 2 versions, end firing and front firing. All work the same, choose witch version that fits your space best.

    That was my next request... please if you could.

     

    Also, does anyone have an opinion on up firing versus down firing with legs/feet?

     

    Also, birch or high density mdf?

     

    Upfiring or down does not matter, whatever works best in your space.

     

    Use Arauco or or BB, avoid MDF.

     

    I recommend the 15" Dayton driver in the plans.

    The guy raised his price after we contacted him.  Not sure I want to do business with him.

     

    What does one of these weigh in Birch?  I need to raise it about 5 feet off of the ground to put it behind my TV.

     

    I don't blame you.

     

    Not sure about weight and would hate to guess, it would take 2 guys to lift as its bulky.

    Can anyone let me know how this would work behind a projector screen.  Will it cause the screen to waive in the wind? 

     

    No problems and not under normal conditions.

     

    Horns are not air pushers like normal DR types but will move stuff under high spl.

    Jason or anyone else in the know.  What are the dimensions of the mouth /opening?  I know it is 24" wide, bit how long is the opening? 

     

    14" x 23" on a 24" wide cabinet

    Anybody who builds a sub uses a high pass filter, that's so basic its stupid. Who attempts to run a sub driver full range?

     

    Oh your an expert......I forgot.

     

     

     

     

    You are probably thinking about a low pass filter.

     

    This will need both a high pass and low pass filter.

     

    With that attitude good luck getting help here, sounds like you really need it too.


  14. If only Radio Shack was still in business....

     

    Their twisted flat wire was cheap and high quality, my 20 + year old wire still looks like the day it was purchased.

     

    Dad used lamp cord back in the day, it did green up like it was kept outside.

     

    As long as you keep an eye out and know what to look for its nothing to loose sleep over.
