Etone woofer availability for Majestic speakers (March 9th 2015)


Several readers have contacted us to say that they've been having trouble getting a hold of etone to order bass drivers for the Majestic speakers.

We have heard that etone are now answering calls but the specified woofer is out of stock and will be on back-order for a few months.

If you don't want to wait, you can substitute Celestion 28/FTR15-4080F or 28/FTR15-4080FD 15" bass drivers. These are drop-in replacements and offer higher power handling (600W/1000W) with identical sensitivity. They are available from the same supplier as the tweeters and horns (Elfa; http://www.elfa.com.au).

We tested the 28/FTR15-4080FD in one of our early prototypes and found it worked well, but thought the etone woofer sounded slightly better and also preferred its lower price. On the other hand, with the 28/FTR15-4080FD fitted, the speakers will handle up to 1000W each (with suitably high-wattage dropping resistors for the tweeters). So it's up to you.

New postage options & prices (January 15th 2015)


We now offer a choice of postage for PCBs, parts, back issues, binders and other items dispatched from our office.

The standard Australia Post charge remains the same at $10 per order, excluding back issues where the $12 charge includes postage within Australia. However, for orders of five or more back issues, the postage charge is now capped at $10 so each additional back-issue ordered costs $9.95 (less 10% for subscribers).

Some items sent via regular post can now be tracked. If we have a tracking number for your package, we will e-mail it when the package is picked up by Australia Post.

We also offer Express Post service within Australia for most orders, for between $15 and $25 per order depending on size and weight. Note though that packages are only picked up twice a week (Tuesday afternoon & Friday afternoon) so same/next day dispatch is not guaranteed. But all packages sent via Express Post include tracking and as with regular post, we supply the tracking number as soon as it's on the way to you.

International customers can now choose between three different postage methods: Australia Post airmail, Express Post International and Express Courier International (EMS). As with domestic customers, some (but not all) airmail packages can be tracked but all Express packages include tracking. Charges depend on package size and weight; it's simply a matter of adding the items to your trolley and then selecting the various postage methods to see the associated costs.

Our office will be open until December 23rd this year. That will be the last date this year that we will send out orders for binders, PCBs, parts and so on. The office will re-open on Monday January 5th, 2015.

Subscriptions can still be renewed and online issues can still be purchased and read. Any other items ordered during the closed period will be sent out as soon as possible after we re-open.

Thanks for reading the magazine and have a great break!

Fraudulent advertising alert (November 21st 2014)


On page 9 of the December 2014 printed issue of SILICON CHIP, there is an ad from "Network Communications" offering discounted smartphones.

We now believe this advertisement is fraudulent and that the person who placed it does not work for Network Communications.

We strongly advise readers not to send any e-mails to the listed addresses as it is probably a scam and you would lose your money.

To make it clear: we believe the fradulent advertisment is not associated with the legitimate company called "Network Communications".

Website upgrade (July 8th 2014)


We have moved our website to a faster server. Readers and browsers should notice some improvement in responsiveness.

It should work exactly the same as it did before, however if you spot any problems caused by the move please let us know.

Update - the Majestic loudspeaker (June 26th 2014)


Progress update - we have located what we believe to be a suitable alternative horn for the Majestic Loudspeaker (see news flash below).

Critically, this new horn is still being manufactured and is readily available at a reasonable price. Allan is currently fitting the new horn to his prototype loudspeaker, so that he can check that the frequency response of the overall system has not been adversely affected.

A new lot of crossover PCBs are in the final stages of manufacture and we hope to have them back in stock some time next week.

Majestic SpeakerLatest news flash - the Majestic loudspeaker (June 18th 2014)


The Majestic Loudspeaker featured in the June issue is causing a problem – it is too popular! Etone have run out of the die-cast horns for the tweeter and the company which made them has gone out of business. Aargh!!

Never fear though, designer Allan Linton-Smith is on the case and hopes to do some tests on some substitute horns made by Celestion fairly shortly and we will make the results known on the website as soon as they are available.

In the meantime, if you have started making the cabinet for the Majestic Loudspeaker, do not cut cut the rectangular hole for the tweeter horn in the baffle – it is likely that any new horn we find will have different dimensions.

We are also temporarily out of stock of the crossover network PCBs but we should have new stocks available within the next two weeks.
