Yes, 2 speed.

The Quilter is a great amp. Whereas most class D's are ICE modules with different preamps attached, the Quilter has a modified QSC K series power section that has been uprated for bass. The minimalist pre is actually very varied tonally and very high quality. Pushing the pre past 2 o'clock results in tube-y sag (but no distortion to speak of). The pre can also be configured as a variable slope HPF at 100hz and has a LPF too if you like to use it that way. I sometimes use my Lehle RMI Classic pre before the Quilter pre or sometimes direct into the power amp section in using a 1/4" jack to XLR lead. Serious punch regardless of the options.

Well..., I loved the tone at home but they were too dark on a gig with my Quilter BB800 (and too small for my Markbass TTE801!) Also I could never rely on them to carry a room. They're very loud but in certain rooms they "run out of breath" like in carpeted acoustically dead rooms IME. I'm sure others will disagree but that was my experience.

I recently bought a Markbass Std 121HR to replace my Barefaced One10's as my small rig. I've done 2 gigs and a jam night with it and I'm very very happy with it. Amongst various other previous Markbass cabs (all the single 12's for instance), I used to own 2 Club 121's which I kind of regretted moving on. The Std 121HR is very similar in design and sounds even better than I remember the Clubs sounding. I like it in kickback mode too.

Sold Lawrence my Barefaced One10's today. Great to deal with, he is an absolute gent.

I love my 1126's. I could have managed with just one though. Feed them enough watts and one would have been more than enough for almost any gig I've ever done.

I thought that was what a HPF was for ! My TKS cabs are FRFR so I'm trying to narrow the bandwidth at the bottom end to replicate the response of "normal" cabs. If your cabs roll off at 40hz then any HPF you add on top of that will double the rolloff curve. Speaker excursion isn't a bad thing - just over excursion. I applaud your belt x2 and braces outlook though

My preference is to boost the bass at 30-50hz and then HPF at 100hz or thereabouts. I doubt if I could hear 1 shelving filter at 20hz if I had a HPF at 50hz especially given the cumulative effect of the natural rolloff on the bass cab.

Also Given the fact that the HPF frequency is the point where the signal is -3db, I'm not sure how necessary two shelving filters @20hz actually are (or even 1!) if you also have a HPF at 50hz. If you google images of "12db hpf at 50hz" it would give you some idea why.

I'm sure it's been mentioned here before but just a reminder how Fishman recommend setting up the Platinum Pro Eq depth control. This of course applies to the AcBsPre sim on the Ms60b and the B3. Depth Tighten up your sound, or dial out deep-bass feedback with the Depth control. The Depth control works hand in hand with the Bass control to bring out tight and articulate lows: 1. Start with the Depth turned up full (5:00) with the EQ set flat on your bass amp and/or PA. 2. Set the Bass control to full boost. 3. Play the bass and back off the Depth (counter-clockwise) until you hear the sound tighten up, usually between 9:00 and 12:00. 4. Re-set the Bass slider to taste. I've always found this method to be really effective.

As I understand it (and I'm far from an expert), the Shelf will just reduce by -12db and stay there. There will still be lower level audio (like a shelf in the frequency graph) underneath the shelf frequency. With an HPF it is the slope that is being referred to in the "-12db/oct" and this means that the slope will continue downwards past the first octave at the same rate until zero audio content.

Zoom haven't quoted any figures (that I've seen) for the LoEq in HPF mode. I would imagine that if they've called it an HPF that's what it does. It certainly sounds like one to me. I would imagine that it would be a sharp slope given the low frequency that you can set it to. A gradual slope from 25hz wouldn't be much use to anyone! *Edit : Zoom's quoted -12db is for the "gain" parameter which is redundant when the LowEq sim is set to HPF *

Well... not exactly but getting there. An HPF set at 50hz will be flat down until 50hz and will then drop off sharply to nothing. The PEQ set at 50hz will start to drop off less sharply but at 100hz or so depending on the Q and then raise again in the sub frequencies. It seems that Zoom were listening to us when we were asking for a AcBsPre sim on the B3n (purely for the HPF feature on the Depth control) but provided a fully fledged variable frequency HPF on the Lo EQ. My Quilter BB800 ,on the other hand appears to have a fixed frequency (100hz), variable slope HPF as well as a fixed, steep sloped 25hz HPF too.

As I said, try it at a higher setting and tell me it doesn't work!

The depth control on the Fishman was designed as an HPF. It works really well as does the LoEq on the B3n.

But weren't you comparing an HPF at 25hz to a bell curve cut on a PEQ that would start considerably higher? If you compared an HPF at 80hz you would notice it and no extraneous frequencies below 25hz at all. You won't hear much if you set the HPF at 30hz or below just like you won't on a Thumpinator. Oh and btw the gain parameter on the LoEq effect doesn't work in HPF mode on the B3n.

Remind me again, what's wrong with the HPF setting on the LO EQ patch on the B3n ?

With the PEQ set at 30hz, the rolloff curve could be starting around 100hz or higher depending on the Q. With the Lo Eq set on HPF at 50hz that is where the rolloff starts. I find on the Fishman Pro Platinum, the sweet spot is around 100-120hz. My Quilter BB800 has a fixed HPF at 25hz and the Deep control acts as an additional variable slope HPF at 100hz when anti clockwise.

When the LoEq effect is set to HPF the gain parameter has no effect. I assume this means that it is already a fixed cut at -24db so using 2 effects wouldn't be necessary. The gain parameter only works in Shelf mode.

The Lo Eq effect set to HPF works great on the B3n. I've used this and the AcBsPre depth control on the MS60B and the B3 in the past as well as the real Depth control on the Fishman Platinum. Mostly though I use the Quilter BB800 which has a fixed Thumpinator style HPF built in and a variable slope at 100hz (-24db) on the Quilter's Depth control. Works well with my TKS 1126 FRFR cabs.

I have an NS CR4M and I get an authentic sound using Spirocores and a hair scrunchie that goes right around the body and positioned just over the bridge to reduce sustain. It's important too not to use too much bottom end in the sound as a real DB is inefficient in this area due to the constraints on size of the sound chamber. I've had best results using a Fishman Platinum Pro (old design) with the Deep control adjusted to 11o'clock area into a Markbass Minimark 2x6.
