The JTR stuff is OK, far better choices exist than the OS Pro for 30-40Hz + IMO but perhaps none as cheap. Have fun!
What's a b2?

@Ricci seems to be a pretty serious fan of the new ds115, even over the sw152 AND it's cheaper. I dunno. I want to max this thing out and get ipals, but that's quite a bit more coin to say the least, not to mention a basic requirement for a SP amp.

Yeah, no kidding.

At less than half the MSRP of the IPAL's, I wouldn't feel so bad about using the new 115's.... as long as they worked in the SKhorn, I mean.

They are on the list that Josh posted of recommended drivers. More efficient, more usable xmax than the 152, and a better pricetag. I'd leave a dB or two on the table not using the iPals, but why would I ever need them?!?!?

Ricci have you considered a V2 that has the ports redesigned for the single port option only? Or two port? Seems like that's the way most home users would use it, so why not make the lesser ports larger?

Regarding the B&C 21ds115, is LE considered high if venturing into midbass use? It seems all specs went up a notch other than that.

I'd like to think so!

Yeah, the numbers did go up a lil bit but that's in comparison to the 152. Doesn't seem abnormally high or anything. These were designed to do bass. I'm sure they excel in midbass.

I'm not suggesting a replacement, just an option.

If you know going in that it will only be used in your basement, might as well use up the available port area as best you can.

I guess it was just another way of saying, "It was designed for a specific purpose for a specific person. Just happened to be shared to the public. Don't get your hopes up for a re-design based off your parameters."


This is the DIY section. Where you do your OWN dirty work.

Id say the Ipals might give you that last 3dB over the 115 but it is a big investment for that last little bit. I do it but Im crazy or perhaps stupid.How often will you need that last 3dB...

Dont forget that the port has to get a lot longer with the extra area too. There's not much space to do that in the current one. Really itd be best to make the vented volume larger and make the ports bigger for the lower tune but them its turning into a proper fridge of a sub.

specs:


2 x 18" ported horn; power handling 600w rms.


http://www.dbaudio.com/en/systems/ca...ocumentation-4


response:





guts:












without equalization, that short horn path is going to put a big spike in the response (and efficiency) in the ~110hz ballpark, which appears to be why ds likes it, apparently.


rough model.


displacement:





efficiency:





sub has cone motion displacement dip at ~110hz and efficiency from ~110 to ~150 is greater than 25%, both of which would reduce distortion.


looks like one heck of an mbm.

Well I would have bought DS115's for my future Skhorn had I known they were coming out. Instead I will be building mine with SW152's.

Beast I didnt know you had that much room under your center channel for a Skhorn. Wow. Should be awesome.

I won't be running it all ports open so the top ports which will be plugged are going to be behind the screen still. I'll flip the center to fit on top of it with a stand that should align the horns pretty closely with the left and right speakers. This at least is the initial plan. Lord knows I'll likely change it up at least a dozen times. Going to finally get the danleys out from behind the screen and spruce everything up real nicely.

Your making an assumption here about me liking it and why, I said it's my favorite BP, that's all. I do not want one for my own use as it doesn't meet my criteria, I chose not to buy it when I was looking some years ago. BP isn't my thing. Also that internal pic, is that from one the DIY copies? Got a link to thread? People here will likely like the Martin ASX or Void Incubus Sub more is my guess.

Also MBM? Et tu? Lol Clearly a sub IMO.

iirc, you like a big spike in the 100-125hz ballpark for tacileness, and that sub does it naturally in frequency response and efficiency, so that doesn't seem like a bad guess as to why you might like it. if you have a different theory, kick it out there.


anyway, the pic was from a random google image search. it seemed to look like some of the other b2 cab drawings--one had measurements but wasn't as clear as to the form factor for beast's question of what is a b2 (i was kind of curious too). the hornresp are just my quickies based on guesstimates of the parameters...just to get a rough idea of the b2's performance.


looks like art welter has/had one.

No I do not like a peak in the 100-125Hz range. It is my favorite BP because the processed response is what you would expect out of a BP and because it doesn't go too low, also my opinions are based more on my own hearing experiences or what I hear from people I trust rather than measurements. Whether it has a peak/dip/X distortion etc is irrelevant to me as far as my purchasing decisions go if I have heard it or if some one I trust has recommended it for my tastes. That said if you find it relevant I find that using a bandpass filter on a flat sub response can create an interestingly unique sound and if done right can sound good, to me anyway. So YMMV.

Ebay. Memory foam chunks.Jammed them in behind the wood port blocks.Little weather stripping for good measure.
