Peshkov Sub - Scoop / Tapped / ARLS???

@Ibex.. as you say most TH designs don't use a chamber, though as mentioned by Johan they will generally then need to have a longer horn to achieve the low end response.  Cabs sizes for either approach will probably end up similar as the extra horn or the chamber will take up a similar amount of space.

@Johan.. you mention that an 18" tends to play flatter in a given design than a 15".. what in particular about the specs do you think is causing this result? Is it ratio of SD to driver BL or FS, or something along those lines?

Okay guys, so it's on me, what kind of enclosure i would prefer... maybe i will build both (tapped & microscoop) and then make a decision.
Before i will resimulate the scoop designs as a tapped one...

stay tuned an keep me up-to-date with your results relating to dependence of SPL between the 2 tapped resonance peaks on driver parameter.

maybe thats interesting too:

If someone has to questions please write me.   This is very fast hi spl subs.Best for very fast bass lines,like drum n bass bass lines. This subs was used in different clubs in "Blazin" party of dj Profit in Moscow,concert sweden rap-dancehall artist - MillionStylez in the club Yellow Moscow... and many others   so i can just tell pluses and minuses of this subs in use:   PLUSES: 1.very fast responding bass reproduction,ultimate for very fast music like drum n bass music 2.when use stacks of its - u got extended lower bass,but still fast  3.hi spl for ultimate mini size 4.very useful,easy move and transport,u can drag and move it by 1 person,and very easy with 2 person,easy placeable in small spaces like small rooms,or if you need to move it in limited passes like ship`s traps and other situations,when you`ll have big problems and many people to load or unload water transport e t c... 5.hi power and durablilty thanks to 12LW1400 power driver 6. very LOW total system latency - bass vs mid vs sat - so singer hear no chorus effect with monitors portals and singer`s voice 7. easy divided to few small sound installations or combined into one big installaition. 8.can be used like low-mid bass section,and extend any sound system if needed ... and sometimes i hear bassists replics - wow it sounding as fast as my bass combo!!! and i hear all notes i playing!!   Also i have 4 of WSX re-designed by Peshkov for PD1850. sometimes i used 1 peshkov sat+2 WSX pers side and powering  up mid bass section with Peshkov`s small subs,converted to lo-mid sections in this case  and i have i clear ultra fast bass lines and still very low latency - so i not use special latency for make WSX faster - i just use latency sat-mid-midlow and WSX play like they can))) but extend hearing lows   In some cases i use only Peshkov sat`s with WSX too - he wrote about before   If any questions - please ask me And big thx fo Maksim Peshkov and Eugeniy Goryachev again again and again

Hi Bomber!
Very cool what you haver writen!

Do you use the WSX Subs stand alone as well? Isn't it better to use 3 small Peshkov subs instead of one WSX, does the WSX (stand alone) have an lower cut-off frequency than 3 of the small subs???
Where are the crossover points, when you use 1 Peshkov top combined with 1 WSX, or what's the lower cut-off frequency of a Peshkov sat?
(questions based on following post of mine: http://www.speakerplans.com/forum/forum_posts.asp?TID=27673&PID=276714&title=peshkov-sub--scoop--tapped--arls#276714 )
I think it would be better to make a stack of 4 WSX instead of 2x2, because the WSX is constructed to use it in arrays of 4 and more...

Would you be so kind to tell me the outer dimensions of a small peshkov sub?
How does one of the small Peshkov subs work when you use it stand alone?

Do you have any pix of your system to post?

ibex you appear to have the wrong s/t peramiters for the 12lw400, i have BL=24.5, Re = 5.5, mms 95, Le = 1.72, cms = 1.14e-4 and rms = 4.16, are you using an older version of the driver?

Hi!
I think you have an old one, mine is from 02/03/2009 loaded from www.eighteencound.com...

V18-1000

You really do need to search the forum and read up on WSX.

A number of members have built the WSX, and used either V18-1000 or Celestion.
