I bought some fairly cheap bookshelf two unit speakers, and they sound fine as long as they are at least a couple of foot away from a wall as they have a port in the back of the cabinet. However they are described as bookshelf design, and of cours as most bookshelves are on walls this somewhat makes the port at the rear a silly design. Not only that but they have the keyhole screw head...

A mid range unit - say about 4" - in a suitable sealed box. Remind me of the difference between mounting it on the rear of the baffle, front, or recessed flush to it?

My bedroom is almost square with one corner with an airing cupboard and the next one sliced off by the chimney as it runs up from the floor below. It has this middle sounding honk no matter what speakers I use.

I notice that Manx Radio is now the strongest station on Medium wave at night on 1368Khz, and its jingles proclaim the nations station. It even fades like Luxemburg used to.

BBC FM channels back to normal, or even better than before, although this might be because I paid a visit to the loft and cleaned up the connections to my 3-el loft FM aerial. Mind you it has now become nice and dry which seems to help. Does anyone know what they were doing for so many weeks ?.

Just to let people know that I have now made freely available a PDF version of the book I wrote mumble years ago on Information and Measurement. Can be obtained from http://jcgl.orpheusweb.co.uk/InformationAndMeasurement_PDF_Book.pdf The explanations use various examples like CD Players, etc, to illustrate the underlaying methods and science.

Hi, our local Talking newspaper has a problem. The problem is this. The sound hardware both in the pc and the cheap Behringer box have got a fixed level monitor of the input, not even mute works on the latter and the internal card only has level monitor adjust if you accept latency, which is unacceptable. Are there any reasonably priced sound cards or usb interfaces which allow simple...

I have a pair of Tannoy IIIlz speakers which I've used for many years and apart from cleaning up the switches in the crossover at the back, they have performed well. always a little on the bright side, they do seem in recent months to be getting significantly brighter, or kind of presence heavy. I guess it could be my ears aging but I did wonder if it might be time to either get them tested...

How do these work if only a 6 inch stub sticks out of the roof ? To get a decent FM signal indoors I need a dipole of some sort that is about 59 inches long, plus reflector and director.

Last year 2017 was the centenary of the birth of Ella Fitzgerald, probably the greatest female jazz singer of all time. To celebrate, the big band in which I play tenor saxophone, put together a tribute project with our singer Ida and played ten concerts to capacity audiences. We used both original Ella Fitzgerald arrangements written by Nelson Riddle, and also arrangements written in 1940's...

For quite a while now I have noticed that FM from Rowbridge on the Isle of Wight seems to be more hissy than the previous 38 years. It seems to be worst on 88.50 Mhz, which is R2. I used to have an Aiwa AX7400 receiver which was utterly brilliant at receiving FM and the signal strength meter showed a good signal where I live, about 50 miles north east of the transmitter, but slightly hidden by...

Many years ago Toshiba had some globe speakers that sounded quite good. Basically they had multiple drive units moundted in a shape a bit like a dodecahedron and covered over with a global mesh. The main construction was di cast aluminium. You needed a bass bin as I recall, but they sounded quite good. I wondered if anyone had continued with this type of idea since it kind of turned the...

I have a relatively new computer which has two brand new cd/dvd writers in it. Neither of them seem to be able to produce universally readable standard CD recordings. Many cd decks give up when looking at them, but a DVD or an el cheapo cd player from tesco read them fine, as do many in car units. These are standard, not mp3 cds.

I have a Beogram 2202 turntable, that could do with a bit of attention. I don't know if it's economically worth it, but it would be nice to have it running in top condition again. Can you recommend a UK-based service for repair and service? Thanks. Daniele

My ancient workshop amp failed. Took the mains fuse - and a replacement. It was assembled from bits I had lying around - including a mains transformer I've not quite sure what it was made for.

Yesterday I decided to bite the bullet and trace the fault on my right hand channel old speaker wire that is for the other room.

Do speakers change with age. I seem to recall that my Tannoy LLLlzs had more bass when I first had them.

I'm going to need an audio source, so I thought I'd try building my own with a Raspberry Pi. I'll be playing ripped CDs, from a USB flash drive, and Internet radio. It will certainly be more convenient than having my CD collection spread over two locations. I now have a Raspberry Pi running Volumio, with a board-mounted DAC (Allo Boss) and a touch-screen.

Mate has a 20 year old AV amp which is getting past it. Switching is giving problems despite cleaning. He'd like a new one with HDMI and toslink etc inputs, that he can use with his existing surround speakers. I've not kept up with this side of the market at all.

Hi just joined the forum. I recently decided I wanted to start listening to vinyls. I was initially looking to buy a linn LP12 but after some research I decided not to buy an LP12. I now proudly own an Ariston RD11s. A client at my work lives in Eaglesham close to Tiefenbrun. I will ad some more info later as I must head to work.

Hi everyone I'm new to this I was hoping someone could help. My DAC sat down on me the other day and I'm reluctant to scrap it if it can be fixed, the power light comes on but no lock light if anyone can fix this or might have one to sell I would be interested. Many thanks.

I realise now that there has been many concerns about the Quad FM 4. Can anyone help with my Quad FM 4 fault, maybe someone has the same problem. The stations will not memorize. Manual tuning works but when the station number preset is selected together with tuning button no memorizing. It just goes to some random frequency readout? New IC1 replaced.
