I am flat broke. I spent to much while fretting about rounds. When she finds out it will be my neck on the line,,, (slinks back to the Den Of Iniquity Thread).

Not all plywood is heavy. Birch is and it is as tough as hell, spruce is very light and was used for the prototype BC112 MK3. However spruce is softer than Birch. Poplar is a good compromise. Its all relative. My BC112 MK3 weighs 12.4Kg, not as light as the GR equivalent but similar to a Big Baby II. It is also very well balanced.

My mistake. Sorry.

That's great. I love it when people get the gear they want. However the 410+ is listed as a wooden cabinet on the GR website.

Me neither Mike, I have both on my basses (not at the same time of course). i will be honest I don't like either. I hate the tension of most flats and the string noise and extra friction of most rounds. I know my technique is lacking and I am trying to improve it but until I can get a round with no string noise or lower tension flats, I will continue to hate both equally.

I think the the point is that the ideal material for a cabinet sonically is MDF but that is too heavy and is not very resilient to knocks and it is very heavy. Plywood is not as good sonically but much lighter and very tough, that is why some types are structurally sound and approved for building. Carbon fibre or Graphite is very light and, with the help of bracing can be quite strong. The reality is that to achieve the strength of plywood you need a lot of bracing. So it can be light but not resilient. Now you pay your money and take your choice but, even at 70, I would forgo the 2Kg weight saving to know that my cabinet will almost certainly be intact at every gig.

That is really what I was saying but I was trying to be tactful.

I checked the tracking on the amp modules early last week, they were still in China after 4 weeks. The back panel had been delivered...to my old addressand to top it all, The amps I was looking at befpre were all now in stock.....Gr. So on Thursday I had to take SWMBO (is that sexist?) to the hospital. On the way back we called into my old house and collected the front panel. Phew! Arrived home and voila, a small but very visible from the road, parcel containing two power amps. Two power amps that were still in China according to the tracking website. So after convincing myself that the satisfaction of building you own was more than getting a mass produced item, I started sneezing and have had a heavy cold ever since,🤧😁 Yes blame me for the shortage of Lateral Flow Tests. The back panel and one power amp is below. The screws on the sockets are silver and I was considering buting some black ones but the small slide switches need M2.5 screws and those are harder to get than M3 or above. The amplifier modules from Connex come with all the cables so wiring is reletively easy. I have to get over this cold however to carry on but I will keep you posted.

Correct. It is only limited by the maximum voltage , maximum current (amps) and the imagination of the marketing department.

According to Infineum "All the power ratings are at clipping power (THD+N = 1 %). To estimate power ratings at THD+N=10%, multiply them by 1.33" With a square wave output it goes to 1.414

I think this is true if you compare Barefaced with older cabinets. However there are number of cabinets that woukd be as loud as Barefaced using high quality modern drivers.

I have criticsed the use of carbon fibre as a cabnet material but I think this is just early days in the technology. Against all my concerns GR can change the designs and hopefully prove me wrong. Of course the bset wat to strengthen carbon firbe is with wooden braces between the layers of carbon.

Keep them elves at work.

The more pics the better.

This is bringing back memories. looking good.

I should have known better than to invoke the DoI. It’s like I broke the pentangle and let the demon breakthrough from one reality into that other dark place, speaker building. Now it’s time for me (no one else can do it) to invoke the straight banana sending all DoI Demons back to the Den from whence they came.

I think wwe just hijacked the Den of Iniquity thread.

Answer: It depends how well you roll them!

There is no such thing as a silly question. only silly answers.

I bought most of OBBM's stock when he retired and have since added to it.

That shows Shuko power sockets as used don la continong.

I use mainly Neutrik. The plugs are solid construction, wheras many jacks are riveted and can come loose. For other brands it depends on the range. The HiCon silent jacks are superb.

Unless you are using a bass/guitar with a Strat type input plate, I find it best to use right angled jack at the instrument end and a straight at the amp. The only basses that use the Strat type input plate to my knowledge are the later Fender Aerodynes If you are going into a pedal or pedal board you may need right angled at both ends. In my opinion right angled jacks tend to stay put when pulled so are a beeter bet. There is no technical reason why you shpuld shosse one over the other though. I make all my own cables and sell a few to fellow basschatters so I am a little biased. However most branded cables should be avoided. The long moulded plug covers or long pieces of heat shrink, often hide poor quality components I have heard good things about Planet Waves. Lynx make good cables and Designacables are recommended by many on here. If you want a quote or just advice, eithe repy or DM me.

Bill and you are correct as my comment missed one vital parameter, frequency. It assumes a fixed frequency and ignores the effects of power compression. I am also fully aware of both the power law and ohms law and it is nice to see others are too.

The saying's go "no news is good news" and "good things come to those who wait" Well both or neither could be true here. I was told it would be 4-5 weeks for the rear panel and accepted that, Sadly the Class D modules seem to be lost somewhere in Chine. I am wondering if the decisions I took were correct. Ironically the "VU" meter had arrived and I will investigate that more later. So the next decision is when to cut my losses and raise a PayPal dispute? I notice that many power amps on Thomann are now showing short lead times and I keep saying to myself that the build was really an excuse to learn about DSP.... More shortly.
