Need some suggestions with these

I've been picking my brain - and google - to figure out how to get the best out of my pair of Mogale 18" Super Scoopers (figured out they were Mogale's by climbing in and having a feel around inside, lol)... Before i get into it, let's dive into a shallow bit of history of my experience with bass cabinets.

................

I've heard my fair share of reflex boxes, single and dual 18's facing forward, single setups and stacked, a variety of port configurations, indoors and outdoors - but I've never been satisfied with the impact of the low end below 45-40hz - and yes, I can hear it - more importantly I like to feel the impact of my system.

The system in my car plays over 145db @35hz so I know what I'm looking for in terms of sound signature when I judge these cabinets - reflex sound great but I'm not about to spend stacks on amps to drive 6 to 8 2000w rms dual 18 cabinets.

I have 4 of the EV 1810 styled bass cabinets (just the bottom), 2 of them have slightly smaller chambers than the other 2, but they're serving me just fine for now. I've also built 2 Nexo LS1200 styled cabinets that I'm quite pleased with - So it's fair to say that I'm trying to find a decent balance between SPL, portability, and low end extension - I will create another thread for all of these projects once they get going.

...................

Now, back to my dillema - these Scoops that I have...

Firstly, external dimensions;

760mm D x 638mm W x 1220mm H

It's hard to find the Void, B&C, or the Fane drivers where I'm at (South Africa)... Even second hand is quite pricey but there are recone kits available for the Fanes so I'm still on the lookout for a decent pair. I've been considering some Beta3 drivers, or even Celto - but i'd still have to save for a bit.

I had the cabinets loaded with Genesis GE-18A 1200w RMS 8ohm drivers - they sounded good but I know the cabinets can sound way better - I used to have them loaded with an ancient pair of Infinity Dynamics 18" 300w RMS drivers.

I've read that the sweet spot for these cabinets are around 20m so maybe I just haven't given them a proper test outside with the new drivers, although I can see them struggle once the frequencies drop below 40hz - as I've come to learn after reading up here also.

PS - I've also read through the ROG transcript where he spoke about them.

I haven't lined the chamber with polyfibre so that's the first step, but afterwards I'm a bit lost as to what to try in them next - what should I be looking for when looking for drivers for these?... I'm considering building 2 to 6 more of these, as well as 6 more Nexo LS1200 cabinets, so any input based off of experience here would be greatly appreciated.

I'm considering a few double 18 cabinet designs for my next build after the Nexos, but if the Scoops seem like a better option for me then I am going to go that way.

I plan on using the Nexos mainly for smaller gigs indoors (2 to 4 a side), and using them outdoors with 4 boxes a side if need be.

The 1810s, I use them both indoors and for smaller outdoor gigs, although the 4 of them together create a decent mouth for bass extension.

Keep in mind I'll only use the full stacks for outdoor gigs of 1300+, not all at once.

I'm keeping the scoops for my larger outdoor gigs for the punch and long throw - if i build 2 more I should get a nice 35hz cutoff when I use all of them, and with 8 I should be able to hold some decent low end levels in open air... I understand that matching cabinets will take processing and delays - I've read up on it.

Right now I'm stuck on pulling the trigger on another set of 2 Scoops and build up to 8, or build a pair of double 18's and slowly save up to build another pair.

The doubles I'm considering building look like these;

I thought of building hogs but after a lot of reading, I don't think they're going to have the punch I'm looking for - I want some nice kick below 40hz, possibly down to 33hz.

So yeah, any input on my situation would be awesome.

I love these Scoops - I've had them for over 10 years, but a lot has changed since then - I understand power density and such but there's just something about a line of Scoops that speaks to my soul... I can compensate for small dips here and there with EQ if I notice it (can't afford those fancy mics so i tune by ear, does me good so far), so I'm open to ideas here...

First step is to buy that polyfibre though, lol.

Thanks in advance everyone.

But I will tell about my personal first hand experience of mogale superscoops vs. Hogs. I haven't heard them directly facing off each other. The stack with supers I know consists of 6 unmodified (with dogleg), loaded with PD186.  They do some serious pressure and weight, but struggle below 40 Hz even 6 stacked together. It just falls apart somehow. The B&C loaded Hogs on the other hand sound just as heavy, but also deliver some smooth low bass 30- 45 Hz. I've been to many roots and jungle dances with these. Usually wither one or two stacks of 4, with half usb kicks. 8 hogs on a digam k20 is epic.  I'd strongly advise to modify your existing superscoops. Driver choice is a tough call. The premium, high grade drivers do offer significant benefits under the right circumstances.

If you have any links to that, that would be great.

Back to the issue at hand... How can I modify them, and what can I expect from certain modifications? I'm all for DIY but at the same time, I don't want to ruin them.

I know there are threads although finding exactly what I'm looking for seems almost impossible... I can find drivers to test in them from time to time but I don't want to build an entire stack if it's not going to perform as I imagine it would.

Does anyone maybe have a response graph for the Mogale 18" Supers vs the 18" Hogs? That would really help.

Not much music hits below 35hz but the kind of house here has some really heavy notes between 27-37hz, some reaching below to 25hz for some portions - I really want something that hits hard from 30hz up... I'm willing to build the Hogs but I need to know for sure... I'll take the response and start another thread comparing it to the doubles I've mentioned previously.

I've been stuck on this for a while - which is why I started building the LS1200s... I'm thinking of just designing a pair of 6th order bandpass boxes tuned low but I want the horns for the throw.
