using sonotube in a 2way design?

[chrisfrost82]

has anyone ever done this or would it be possible. if i decide to do this i had thought about making a convex top and bottom, so there is no flat spaces at all inthe tube. building my flat baffles out of MDF and fiberglassing them to the tube. i figure should be a very sound eclosure, but i may be wrong. any help would be appreciated

I can't offer you any advice, but this guy...

... may a two-way out of a ceramic sewer pipe! You may encounter some similar problems. Possibly.

Nice one,
David.

I'm not sure what you mean by fiberglassing. Is that how you intent to eliminate the air spaces between the MDF and the tube or just as an adhesive?

You should take a peak at Aaron Gilbert's Emerald Towers. Made from Cubicorn tubes and covered with green velvet, hence the name. Sounded pretty good too.

You have posted a link to an attachment, not a thread

I probably misunderstood. I was assuming you were putting the sonotube inside an MDF enclosure. Creating an elliptical interior is a worthwhile goal. To eliminate the parallel surfaces of the top and bottom just put a sand filled sock in the bottom and tie it down with a zip tie to an eye screw.

i just plan to use the fiberglass to secure and close the gaps from the mdf to the sonotube. i do not plan to crush the tube at all. i have seen someones line array where they crused part of the tube to make it flat. i dont really want to do that, i would just prefer to keep everything round. only reason for me choosing sonotube is cause i can get it locally, dont want to pay the herendous expense of shipping Cubicon cheapy i am. i already have 2 way towers MTM design built out of MDF using parallel sides (i know i know) drivers consist of 2 Audax HT170f0 6.5" midrange/bass and 1 Morel MDT30s tweet per tower and same config for my center channel. using just a single 6.5 and tweet for surrounds. Xover was designed and built by madisound (first set of HT speakers, still kinda new, didn't want to mess with it right now) used all Sidewinder. poly, expensive things they were. but as of now tower are not finished still raw state. 1.2 cubes tuned to 50hz sound nice, but i think they could use a little help on the lower end, not quite what i expected. for my subwoofer(s) i am using 2 eclipse aluminum 12's 88012 or something like that. only running 1 as of now in a 3.5 cube box tuned to 24hz. running off a PE 250w plate amp. i have my Crown XLS402 sitting here but i think i broke it, wont get into that right now. but that is an over view of what i have so far. oh and for reciever i got a Sony Str-de875 5.1 100x5 at 8ohm, does me nice, looking to upgrade. thanks for reading this if you made it all the way through
