It is unlikely this will be your last FR build

Start cheap and work your way up.

Yes, A7 is better than EL70, but it will show every wart on your choosen amplifier.

Thanks Dave, I think I'll just go with the EL70, I don't think the difference is going to be really worth it until I start focussing on my source which is a little bit down the line.

Attached is the revised plan.
I've tweaked the sizes a bit for easier cutting. It has resulted in a bigger box but I've kept the ratio to 1.4, so I reckon it will work!

Is chipboard a huge compromise over plyboard for this design? It's about 1/4 of the price!

Well, EL70 drivers ordered. I'll be going for the design that I posted just above and I'm really looking forward to it!

Quick question - with the inverted BiB, how far off the ground should the box be, or is it again a matter of finding what sounds best? I am thinking about experimenting by putting blocks of wood under the corners first, but if there is a recommended amount then I will just make the sides longer and have a front and back vent..

Yes. Quite a bit of tuning latitude there.

Ok, I'll build it as designed and then use blocks of wood on the floor to raise or lower it to find out how high the spikes need to be!

The weather today was about as miserable and wet as any I've seen in the UK or Ireland. That made it the perfect day for working inside on some speakers!

Unfortunately, tools are sparse but I managed to get my hands on a VERY wonky jigsaw and 2 half broken clamps. Oh yes, this was already shaping up to be a successful build...

Anyway, with holes (which looked like they had a stroke) cut for the driver, it was time to start glueing it all together with the help of Selleys Aquadhere. It was at this point that I noticed that matey at the builders merchants had given me warped plywood. Nice one, thanks. I'm too impatient to get it all done again so I figured that, as this is my first speaker project, I'd persevere and see how it goes.

Some Pictures from todays action:

Glueing the second piece (note the expensive water bottle weight)

Glueing down the baffle:

Glueing down the other side of the speaker. I needed this much weight to try and un-warp the wood

Sticking on the top piece of the speaker:

I'm using some pretty ropey speaker cable that came free with car speakers I bought for the Falcon, but that's easily changeable as I'm going for a binding post free design. Less connections the better.

The speakers still need the front fascia putting on which will be primed and sprayed Matt black as per my image above. I reckon this will look pretty good and I may be able to get away without veneering the speakers as the ply finish isn't too bad. We'll see.

In other news - I received a note that I have a parcel waiting for me at the post office All I need to do is to find a soldering Iron for 2 connections on my TK2050 amp and I'll be listening to music!
