Further Information

Hi .. any suggestions on how to mount this speaker in a plastic box (I'm building a bat detector)? I'm thinking of double-sided sticky tape cut to shape in pieces, but maybe there's an easier/better way?
Asked by: Mike Cowlishaw
Hi Mike,

Thank you for question, normally these tend to be held in place by friction fit so if you cut a circle in the plastic box that can hold it. The other way I have seen it done is with a second panel inside the case for the speaker to back onto holding it in place.

Best Regards

Will I need to buy a PCB to go with this speaker as well?
Asked by: Guy
Hi Guy, You would need to purchase some item to enable it to be used, it could be used with one of our amplifier kits.

I need a substitute 50mm speaker for my door-intercom. The current speaker (1993!) says '65ohm 0.3W' but I can't find that anywhere in the world. Will your speaker function on my intercom, given the 2W 8Ohm? Thanks for the answer!
Asked by: R.A.van Rijn

Unfortunately this speaker wouldn’t be suitable, however you are able to get a 65ohm 0.3W speaker but these are very uncommon and quiet expensive. An alternative option is a 64ohm speaker which is a lot more common, most have a power rating of 0.2W but should be absolutely fine.

Hi there, do these come with any fitting brackets? Thanks.
Asked by: Jake Stanger

Hi Jake, The product doesn’t come with any fitting brackets, and we don’t stock any either.

Answered by: Michael Lockhart

Hi could you please tell me how deep this speak is as I have limited space for it to fit?
Also how much is delivery, do I have to spend a certain amount to get it free?

Many thanks

Are these speakers suitable as an upgrade for the speakers that come with the deluxe stereo amplifier kits. If so is the differece in sound quality noticeable better.
Asked by: Gary Miles
Yes these speakers can be used with any of the amplifier kits (mono, stereo & deluxe stereo amplifier) and will sound a lot better than the standard speakers supplied with the kit. It is important to get the most out of the speaker that they are mounted well in the enclosure, so that all the air is pushed forward and out of the speaker. You will notice there is a massive improvement in quality with any speaker if you cup your hands around it which is what the enclosure is doing.
