A long way from you but these might fit the bill https://www.gumtree.com/p/guitar-bass-amplifiers/2-x-eden-ex112-8-ohm-bass-cabs-cabinet/1315199271

I don't think they do. Semi-parametic is cheap and easy to design, fully parametric is more complex and so takes time to design and is probably four times the number of components. The pedal option is probably the only option to be honest unless you are using some kind of modelling software.

Same rig as Glenn Hughes uses then?

I agree but with a fully parametric control (one where you can adjust the Q (quality or width) and frequency parameters with a pot, you can cover a lot of the mids and not have a notch or peak at the crossover frequency where a high mids/low mids semi parametric system meets.

Sorry to resurrect this thread but I have just read the spec on these and it is quoted to consume 110W at 1/8 power. So Max power consumption (not output) is 880W. If we take the M version, that probably has an efficiency of approx 85% (assuming both power supply and power amp being are over 95%. I am giving Behringer the benefit of the doubt here.). Then the real power output is a tad short of 750W. Now it ain't the 2000W the Uli's bad-boys claim but it is a powerful amp. Even with a more realistic overall efficiency of about 80% the max output power is over 700W. Of course we have to add the caveat that there are no distortion figures but it should output some serious power. I have also realised a slight bias in the way people (including me) view baked in compression. It is seen as a good thing in valve/tube amps where is is merely a chariteristic of the valves. In solid state devices it is often mocked despite the fact that it is probably this valve compression that gives the impression that valve watts > solid-state watts.

As i see it there is no need to go to 50Hz. 30 or 35Hz is ideal but the real thing is that the filter must be steep 18-24dB per octave.

Perhaps I should have said any type of boost below 100Hz that can be added to the existing preamp bass/low shelving, plus graphic/parametric EQ and sub bass/octavers that go an octave below. Not grammatically correct but hopefully clearer.

No slow evolution really.

My only concern would be that slot port. Looks like ease of manufacture may have overridden absolute performance?

There is a gentle slope with no EQ but not quite enough IMHO for a decent HPF. The 30Hz at -15dB is more like it but you are affecting the sound as the 100-150 region is also affected. This is where the old school, hump is usually found. A good HPF will leave the area above 70Hz untouched. However in Ashdown's defence there is a degree of protection for speakers with that roll-off with the EQ switched off. Now if only they and others would ditch the deep or Sub switch.

I was of course tongue in cheek. However it really makes little sense for anyone to design their own power sections. iCEpower, PowerSoft and others have have it cracked and have the volumes of scale to be both cost effective and reliable. Propriety class D design nearly crippled Ampeg with the PF 500. Another reason for me not to buy MarkBass.

I am sure I read somewhere that MPT is Marketing Piffle and Tosh but I am finding it hard to find the link having been blinded by looking at a Ninja.

In my opinion it is vital in a modern amp.

Duke le Jeune of Audio Kinesis says that a -3db point of twice the fundamental frequency works well. That coincides with your figures for the SVT. I must admit though that I would prefer a bit lower and then dial it out electronically if needed

I ask myself whether they screwed up and meant to release it on April 1st. On a serious note, it is a Pre-Amp with a DI output.

Here are cone extension and max power graphs.

It models well at 30L tuned to 50 Hz.

I have Picato Flats on my Greg Bennett Semi Acoustic but they are now rare and I am looking for an alternative. On my Fender Aerodyne I have Ernie Ball Hybrids. I have heard good things about Chromes but I am thinking about going roundwound on both. A set of NYXLs might be just the ticket.

I took my home made 1x12 cab (The Basschat 1x12 Mk2) to Open Mic night about a year ago and another bassist played through it. he was blown away by my amp. A little Ashdown MyBaas 220. This outputs 100W into an 8 ohm Cabinet. I told the Ampeg using bassist that it was the cabinet not the amp. The cabinet has a 5" ports and the amount of air that goes through the port and into your leg is astonishing. Massive trouser flapping. It just goes to show that you have to look at the rig as a whole.

Some amps mute the amp when there is no inPut jack inserted. Insert the dummy jack and it unmutes the amp.

I have nothing against a hybrid but I cannot see the point,. Many hybrids have a valve front end but most people think the valve sound comes mostly from the power amp. It probably makes more sende to have SS front end and valve power amp but the weight and size saving is minimal.

I agree but it is a b*gger to read the panel on the chrome front.

The output increase from the amp is 3dB and form the extra speaker between 3-6dB but this is only in the low register (depending on how they are located and who you listen to) so your mids and highs will be 3 dB louder and your lows 6-9dB louder. The other factor to take into account is that if you play very loud, the single cab my be approaching power compression so the difference may seem even more. Two cabs my not be suffering from power compression nearly as much.

Sounds like a plan but go easy on them drivers as they may well exceed their Xmax at medium to low volumes. litsen for farting nopise and if there is no nasty smell it may be you driver exceeding its mechanical limits.

The picture makes the escutcheon look glossy. I mistakenly thought that you misread the subject of the thread.
