    Re: Event Horizon: a slim, wall-mounted WMTMW

    Thanks for the reply Paul. I just took a look at the B4n simulation using Jeff's woofer box designer, and it looks like a F3 of 50 hz is possible in a vented enclosure. I am guessing you were wanting something into the 40's?

    Right now I am torn between trying this 3-way design (vented or PR enclosure) or a two-way using silver flute woofers and the Dayton silkie. The silver flute design could be a single W20RC38-08 8" or a dual W14RC25-04 5-1/2" wired in series. Both have about the same F3 frequency in 20 L volume with the Dayton 8" PR. I am really looking to keep cost down below $100 each (not including cabinet cost). Any thoughts on which design would be best?

    Well, I can give you what I've done (ND105-4 + ND90-9 + ND20FB and HiVi B4n + B3N + ND20FB versions), although they need a sub, and therefore didn't quite meet my design requirements. I've had a back-burner version for quite a long time that--if it works--won't require subs. But I just haven't gotten around to building prototype cabinets for it.

    Honestly, this project wore me out. I'm on my 4th or 5th set of prototype cabinets for it; and just couldn't get the bass I wanted (hoffman's iron law and all that). So... maybe this is one of those times I enlist the help of another cabinetmaker if I ever want to finish the project.

    Sorry to bring this back from the dead, but did you ever finish this design Paul? I am looking to build a wall mounted speaker for my living room (wife banned my towers to the basement), and this design might be just the ticket.

    The cabinet drawing in the first post clearly shows a back on the cabinet.

    Sorry to bump this thread again, but I'm about to order the MDF I need (this is for the Overnight Sensations CC build, as you recall) and I'm simply not sure about the back - from your drawings, I just noticed that it looks like you've no rear baffle at all? In other words, the wall is acting as the back portion of the speaker, is that correct? If so, I guess I'll be adding another 1/2" to the depth of the speaker, because I'll want to be enclosing it.

    Or, am I misreading and you DO want a rear baffle, but maintaining 5" depth?

    Thanks!

    Right. I mean, you could separate it into chambers, but it's not necessary with this design.

    I think it might have had a bit of bracing, but nothing fancy. 2 or 3 dowels or scraps tying the side walls together here and there would be fine.

    Just the answer I was looking for - thanks a lot, Paul. =) That simplifies things a lot for me. Just confirm as well, that the cabinet has no internal bracing? It's just a box, basically?

    Got it, thanks. Replied in your thread. For anybody else who might know - can the Overnight Sensation CC be used vertically as a L/R main?
    Yes. Paired with a sub, I think it would work well in your application.

    Paul would need to comment to be sure, but if I remember correctly, he voiced that specifically for vocal range.

    It might be a bit shouty for mains without an XO adjustment. (shouty being technical audiorific terminology)

    I am building them. Currently on a hiatus after having finished one speaker. I have been listening to it as my CC since Jan, using some Overnight sensations as the mains. Looking to finish them by end of the this month.

    Here is my build thread.

    I realize this is an old thread, but I'm wondering if there are any updates? Has anybody built these? I'm seriously considering them for a TV stand project of mine, they're nearly perfect for me.
