thanks davey, i think this design could sound realy nice, im betting it will have a nice hard hitting sound, maybe even a HD15 alternative with better cooling.

Thanks for the enthusiatic comments guys. Yea, you can chop it in half if you want to make it a single. I'm not sure it would make the best upper bass cab, probably wont sound as clean as the hd

I had designed it with mounting the drivers with the magnets inside the speaker... but i guess you could always try it the other way round!?

Surely box look to be fine for intended use.
I have designed pretty reminiscent version (single 15 instead double) ..I will find some pictures later

But still I would not place those in scoop category :)
 ..I assume that something to be rear loaded horn a.k.a. scoop must have noticeable horn "action" (tending to be long more or less but close to 1/4wave length of low cutoff)

In my opinion it will fall more under "advanced bass reflex" .. or "light" version of serial tuned bandpass 6th order box.

I do not want to be meticulous .. It is just way I look on thing.
..And maybe to help some fresh-newbie to not be confused and start to assume every bass reflex cabinet with a bit longer port (or "L" shaped port) as scoop (or mini scoop :) )

Best wishes (always)

Yea calling it a scoop is a bit wrong really. There's no physical "scoop" to it. I'l rename the post something else as soon as i think of a good name. 

Yes its more like a horn flared series tuned bandpass enclosure. It definately has the response of a bandpass cab with the steep dip at 200hz

I'l post the HR model. I stuck in 20cm as the offset between the driver and the horn mouth which takes a cut from the upper bass response

Its difficult to say how low it'l go. The proof will be in the making and listening... don't worry. You won't have to wait long :)

it looks like the parts would fit ok in the sheet of ply i have left at home, its not too big in singles and the frequency plot looks good for an upper bass cab to play reggae.more efficient than a standard reflex cab but with different sound than hd15 or turbosound style bandpass horn, like 3 singles above 4 scoops

so i think about building a prototype and see if with a midbass driver it has a good kick at 300w amp power with crossover points 80hz-160hz , and also if it can work good in a home set up as bass cab with low amp power 50hz-130hz where i dont need much sub
 
the driver i'm going to use is this one http://www.sonoraspeakers.it/schede/Z00830.pdf not really a subwoofer but was sounding good in 15"reflex cabs and has no place now that i have tse118 as upper bass cabs

thanks davey t!

i'm getting seriously keen on the idea of build a 12v system and have a pair of p audio c15 600lf sitting unused- do you reckon they'd be any good in this design? i've been playing about in HR and winisd with little success in terms of compact designs.
the only thing more dangerous than a person who doesn't give a f**k is a person who gives a sh*t.

Davey

Altough not entirely similar but could you help me with my 15 minute effort. I first did it in sketchup, measured throat and such points and tried it out in HR

http://www.speakerplans.com/Forum/tiny-kick-bin_topic27251.html

As you can see, it ended up pretty flat, but could you explain how did you get 104db sensitivity while my sensitivity is somewhere around 92db, altough the nominal sensitivity of PD is 96db!
