I ordered for some nice midrange in a huge 3-way party speaker I've been meaning to build for years.

Then I thought, such a bargain and, if there's a project going on here I may like to have a play, so in went another couple of pairs. Then I realised I only needed to spend another fiver to use my free discount voucher, so in went another pair 😀

Maybe some little desktop/lab monitors, and/or sexy compact lounge speakers... Really like the idea of a .5 compensating for baffle step - something that will be new to me 🙂

matttcattt - I can't find a TM025F1 at Maplin 😕

they do do them, but they are out of stock 😱 delivery being within 28 days, they are listed as 70w tweeters in the audio range, we must have been looking at the same time. 😀

Falcon do not sell them nor do Wilmslow, anyone know off any other sources for this tweeter????

or for that matter another alternative??

Well I am studying acoustics at salford uni and im in my first year. Although its not really what I had hoped for nothing to do with loudspeakers yet, and the bit we do, do on the course ive already done myself!

Either way good luck in your exams.

Your project for an escape?? Ive got several on the go! not inc. the audax one, although I suppose I probably will start this one sooner then when the exams are over.

Now to look on ebay for some nice cheapo veneer, got like 50sqfeet of maple burr for £35 the other day, worth like £580:bigeyes:

I was waiting for someone to suggest a suitably cheap matching tweeter - cheers David. I suggest people just pop down their local to pick up that tweeter if you can't get them online. I know my local has a couple of the AP100Z0 in stock and sure it will have the TM025F1 too. It would be nice to know what, if anything, will be dropping price next...(perhaps a tweeter - or is that just wishful thinking)

I find it amusing to see what Maplins think is a suitable picture to illustrate the TM025F1.

Glad to hear you guys have made good use of the WM-61A's. I've yet to use mine!

NO tweeters left at Maplin - No delivery date known!!

Maplin were very unsure as to their next delivery of the tweeters from Audax, my own thoughts are that they will not be getting any more in 🙁 as the order desk girl stated two delivery dates which had expired !!

I have however found a Maplin shop that has some and will get the tweeeters from there. (fingers crossed)

Thanks for the info as to the alternate source but at 15 quid each and 7 p+p you are right in them being at a premium price still good value though.

What are the benefits of non proted enclosure

5th element:- ( or others)

Can you share with me your reasons behind going for a sealed cabinet over a ported one, I would be interested to enable me to understand the theory's behind the design of loudspeakers so that i may apply these to larger more complex (expensive 😀 ) ones.

I am guessing that it is to do with the phase shift or delay?, as the F3 value would appear lower, clearly this is not the only thing to look at in when designing a loudspeaker, so what are things shgould we be considering in our designs?

I guess this must be a good distraction for students all over the UK duiring their exams (as I have to add myself to the list, as I'm right in the midle of sitting my third year finals as part of my four year masters in engineering).

Anyway, try not to bash the people at maplins too much, some of them aren't quite so dim (like me!).

:smash:

(oh, and if people wan't I can check out myself when the next lot of those tweeters will be in - if they will ever turn up)

Well from a design point of view its easier to make a sealed box and looking at the data of how the two boxes perform, sealed and ported, I think the bass loss in a sealed will be negligable or even apparent because it actually plays louder lower. I am a big fan of sealed boxes anyway better bass quality. Usually for a small pair of speakers I would want to go ported to maximise bass output but in this case sealed, to me, would be fine. If you want to go ported then thats fine by me the crossover should still work in a ported box.

Sorry Mr. Parsnip, you know I'm only joking about those Maplins folks, you must understand how annoying it is to get a bad order.

Actually, some (and only some!) of the ppl at the several Maplins I've been to really know their stuff and are very friendly (sometimes just weird tho.! 😉) Whilst we're on the subject of Maplins, how nice is the catsuited bird on the new TV ad they've just been running???

ps - I finished my degree last year 🙁 But unlike you guys it was in an area nothing to do with this hobby - IT! Dull....:whazzat:

Well, rather than start a new thread, when this one is already talking about maplin, which of their tweeters should I get?

The possibles are the Audax TM025F1 and the Motarola KSN1165A, KSN1141B and KSN1177A. Duse to the price and power ratings. (My amp is rated at 70W peak per channel)

I dont want to spend more than £12 each...

I think the TM025F1 would go with the AP100Z0 best due to the lower effieciency, but I want advice before I buy anything. 😀

Hi Matt,

What you really want to see is the frequency response graph, and the impedance might be useful too I reckon - the same might be nice, to help keep it all simple.

You really want the tweeter to play smoothly down to 2khz or below, and hopefully to have a resonance of much lower than that, but if not, never mind. Don't worry about the sensitivity.

Power handling also doesnt matter, as long as you x-over at 2nd order or steeper. 70w isn't going near the tweeter - that will only get used for the bass in reality - unless you actually try to break the tweeter 😀

I'd go for an Audax tweeter I reckon, as being the same brand and relative price point, it might match really well.
