Any other feedback on these cabs, with hefty 5" VC 18" drivers, playing Reggae/Dub.

From plots and measurements I've seen, I guess they need plenty of shaping eq, (Dependant on driver).

Question is, do they do decent 45hz, in stack of 2x !?

As 186 horn will do this with modern drivers, no problem, and is smaller cab.

i had the opportunity to measure my 6 against 6 martin s218 in the same venue if someone cares..... , i was pleasantly surprised to not see the often discussed 50hz dip (could have been the room? but the 218 look worse....).  this is with all filters on (hpf bw24 / 26hz, lpf lr24 129hz)

No comment on the quality of the design or any alternatives, but the Wayback Machine still has it: https://web.archive.org/web/20121119193411/http://www.pcorporation.net/SuperBassHornv2.pdf

HTH,

The F124 is in a different league to the SBH. I’d save your money.

I have been planning on designing a 18 inch and 21 inch FLH and posting it here but I have been very busy as of late. I am finishing my masters and moving 3500km to take a new job before the end of the year but I may find time when I settle down in the new year. 


Have you ever seen the Modified Lab sub plans, for a 2x15" version?

There are quite a few modern drivers, that would be better in WSX, than original RCFL18P300.

Would also suggest you go hear WSXs playing, in venues, of similar size, to those, you intend to play them in.

WSX are "NOT" best suited, to smaller venues.

Hey people!Cry I tried to find the Plan PDF from  http://www.pcorporation.net/SuperBassHornv2.pdf - SuperBassHornv2.pdf by Startec since the website is gone down. Please can any of you help out here?

Good job citizensc. Nice to see actual measurements, and those seem pretty stark. That's not a good response at all.

Funnily enough, there still seem to be heaps of free party types building enthusiastically anything from 4-16 cabinet sized stacks of sbh's, and circle-jerking about this "amazing bass horn" on fb LOLConfusedOuchDead

The more I have learned about FLH design, the more I have come to hate this design. Its just sub optimal, it isn't that suppressing, after all it it is a design from the 90s, adapted to what what was considered a modern driver in 2008, in 2021 we have so many great drivers and design tools that designing something better than this isn't very hard. 

Here are a couple of real life measurements of the SBH in groups of 4, as you can see, it is trash below 50hz. I ran an akabak 3 sim of the SBH in groups of 4 and compared it to 4 x 18 inch reflex and 4 x 15 inch BG horn, both killed it below 50 hz. 




From a real life subjective (ears), objective (measurement) and theoretical (BEM sim) point of view this design does not score well IMO.

I have been planning on designing a 18 inch and 21 inch FLH and posting it here but I have been very busy as of late. I am finishing my masters and moving 3500km to take a new job before the end of the year but I may find time when I settle down in the new year.
