I'm getting nagged at to post something about my new speakers.
I have some Frugalhorns with MAOP 11 drivers, which are more than a little bit special, but had the urge to build my own speakers, so the Frugalhorns are up for sale in the classifieds here.
I didn't take many pictures of the build, but the plans attached are the basis of my 2 ways, and I used Mark Audio Alpair 12PW's and MAOP 7 drivers. My utter lack of knowledge about anything electrical meant the crossovers were built by Stefan at KJF Audio, who also supplied the drivers etc.
I made a few mistakes in the carpentry part, but nothing that anyone would notice, bought a cheap circle cutter which was another one as my circles are not perfect (no-one has noticed yet despite me pointing them out) but so far I'm very happy with the results.
Lessons learnt - wait a bit longer to get Baltic Birch Ply - Lockdown meant that getting some was going to take a month and I'm impatient, so my local builders merchants sold me something that was meant to be devoid of holes/spaces in the inside ply's - I can't say if it makes any difference to the sound but imagine it does, and certainly seeing them as I routed or cut was disappointing.
I also didn't want to spend £87 on one of these - https://www.amazon.co.uk/Jasper-200J-Circle-Cutting-Plunge/dp/B00009K77A/ref=sr_1_4?adgrpid=67786544053&dchild=1&gclid=CjwKCAiAtej9BRAvEiwA0UAWXvpfsg064ywPb5Hd7UaijoYqK-W1jmIpZQMf-Fw8-AylkSTZ2u7T6hoC8e4QAvD_BwE&hvadid=338808665459&hvdev=c&hvlocphy=1007099&hvnetw=g&hvqmt=e&hvrand=14517871881857855373&hvtargid=kwd-356103570367&hydadcr=29381_1700893&keywords=jasper+circle+jig&qid=1606044763&sr=8-4&tag=googhydr-21 so bought a cheap alternative - https://www.rutlands.com/sp+power-tool-accessories-router-jigs-circle-jigs-router-circle-compass-rutlands+m1260 which was not worth the saving as I spent ages trying to get the correct size set up, and then as I routed the screw that held it in place worked loose, causing my circles to be slightly out.
Never start anything until you have ALL parts in your possession - cutting a hole when you have the dimensions on a plan may be fine, but if what you have ordered doesn't come can mean lots of filling and re-cutting. Also, waiting for something to arrive when you are already out in the garage revving up the router is not good. Waiting a few extra days before you start is a lot easier. Especially when a certain courier company who I won't name, but is seen as one of the biggest and best by some, but who require you to download their useless app, log in each time you want to use it, and then cancel a delivery at 10 to 8 on a Friday evening when you have already waited in ALL BLEEDIN' DAY despite asking for updates and expected delivery times is SO annoying. They have now done exactly the same thing (cancel a Friday delivery when I've already taken the day off to wait for them) for another delivery, so I will try to avoid buying from anyone who uses them from now in.
Don't buy peel and stick veneer then keep it in the garage for a few weeks. I did, and a on a couple of bits I'd cut the backing paper started to bubble. I couldn't afford to buy another sheet so used those pieces on the back where they won't be seen and sure enough blisters have appeared that I can't get to stick down (I've tried re-rolling then, using a warm iron etc)
Otherwise it's been a lot of fun, a lot of learning and now I have a pair of speakers that I've made (a dream since I was about 8, when my father who was a musician bought some speakers made for a BBC sound technician - Tannoy drivers in solid teak, almost as tall as I was back then and the start of a lifetime of listening to music). I think they are likely to be keepers, I'm still getting used to them, but so far they sound wonderful to my aged ears.
A brilliant way to spend many hours in a cold garage and more money on tools than I had expected..
