It's likely to be worse. You can easily try it out by stuffing a t-shirt in there to block it up. You'll then have a sealed cab. As long as there's space on the baffle and you don't mind a bit of DIY, you could upgrade the performance of your existing cab by making the port bigger. The driver itself doesn't look half bad. You can buy plastic ports cheaply to give the hole a professional look. One of these would enlarge the port and tune your cab to the same frequency you have now: <https://www.bluearan.co.uk/index.php?id=TUFFBR75&browsemode=manufacturer> You'd probably still need a second cab though.

37 litres is about the smallest useable volume for your typical 12" bass guitar speaker. The big stumbling block is the 5.5cm port, which will compress and make noises at a very low level. Try playing a low E through it and listen. Because the size of the cabinet plays a huge part in determining the efficiency of the system, you can't really make a cab more efficient just by sticking another driver in there. The efficiency at low frequencies is determined almost entirely by the size of the cab. I think your best option is adding a second cab.

I couldn't swear to it, but I seem to recall that when Bass Gear Magazine measured the Markbass LMIII it was flat with all the tone controls at noon. Cabs aren't normally flat though, and your settings are probably compensating for your cab and the room.

Good sight reading practice. Ho Ho. I don't think I could ever play that in a million years.🤩

Love it! I've always wanted to have a bash at that Real Thing line.

Did he write that? Well I'll be blowed.

At the beginning you say that you "work from the top knuckle" rather than bending your fingers - then you proceed to play with curved fingers throughout the video. I think it's great that you're putting lessons online, but I think you need to fix that.

That sounds like a good deal to me.

Try and stop me!

Aha! No, but I know a smartalec when I see one. 🙂

Too right! I was too much of an idiot to figure it out and sold mine.

The big question is why you want a custom-designed cab.

I advertised an Aguilar TH500 on here a couple of months ago for £450 with the case. That's an in-demand, fast-moving product selling at about £50 less than at the beginning of the year. I didn't get a sniff - not even an offer. I then sold it on eBay without too much problem for £525. I'm not sure what to make of that, but the cheap bits and pieces still seem to be moving.

Didn't Passinwind (not someone to exaggerate for effect) say something similar several pages back?

Good points, Richard. The compression driver I'm using for the latest lightweight version is not ultra-efficient and doesn't therefore have a huge amount of padding. The system measures 98dB at 1 metre throughout the midrange, which is slightly better than most, with a tweeter of about 104dB sensitivity. I'm not a big fan of adding cabs willy-nilly - even if they contain identical drivers, because you get cancellation and combing in the midrange, which varies depending on where you are standing. My preferred solution for a second cab would probably be just to roll the bottom cab off at about 500Hz with a passive crossover. That would double the power handling at lower frequencies (where it's needed) and change the sound balance somewhat. I'd need to experiment a bit with that. One of the reasons for adding a second cab is to have a cab close to ear level so that you can hear yourself properly. That is definitely not necessary with this design. You can hear yourself perfectly clearly even when the cab's on the floor and you're standing right in front of it. I can't imagine needing two of these in a normal gigging environment either. One is certainly enough for me. But your mileage may vary, as they say.

There should be some news next week.

You might consider putting some sealing foam where the Speakon mates with the cabinet.
-
Most hi-fi speakers aim for a flat response, because research shows that this is what customers actually prefer. It is true that they don't always achieve it. The boom - tizz brigade that you describe is something else.
-
That is plain wrong. You can have certainly have flat response, full range and high efficiency.
-
No. That's not how to fix the problem at all. Particularly with small, high power cabinets, you can't just increase the port area willy-nilly because you soon run into problems with port length. The best solution is to reduce the wall area of the ports. That means, ideally, a single round port. The only bass guitar cab designer who seems to understand the importance of this is David Nordschow.

No need to apologise, Pea. 😛

Très bien, Jacques.

I've given some thought on how to do the flat packs. To cut the assembly time, the panels need be machined so that they slot together with a minimum of effort and tools. That would make it quite a fun project, with most of the work being in fitting the t-nuts, corners and handles, and painting the box. I'll be publishing a crossover layout on here for those who want to build the two-way and could easily supply a kit of parts. You would need to be able to solder though. Could be interesting.

This isn't really a music video; it's a YouTube video. It's a one-take video like Kylie's - except the music is much better. 🙂 video; it's a YouTube video. It's a one-take video like Kylie's - except the music is much better. 🙂 -
I'll be resuming this thread in a couple of weeks, Peter - with plenty of piccies.
