  1. Best courier for sending HiFi equipment?

    UPS, I deliver dozens of parcels of speaker stuff each week and they have never lost or damaged any of them in over 2 years. Drivers are generally very professional and are driving vans that are kitted out for the job so your stuff doesn't get chucked about.
  2. DIY Speaker Bake Off

    Right, I've added the date I mentioned above to the event calendar on my site. http://www.kjfaudio.com/event/2nd-annual-diy-speaker-event/ Can those of you who want to come pop over there and use the RSVP function at the bottom to book in, that way I've got an easy way to see how many are coming and contact you all with updates etc. There is a comments section at the bottom of the page, if you are planning on bringing some kit could you just pop it in there, I'll curate a list or stuff and post it over to the various fora from time to time. Stefan That's a shame, there will be another next year, I'd like to make this an annual event for the DIYers, maybe moving forward we'll have to move it from the farm to another venue.
  3. DIY Speaker Bake Off

    I'm going to move this, I've been rather busy and think I'm going to struggle a bit to get this organised for mid October. I've spoken with Dave Shevyn over at GIK and November 25th works well for him so am proposing we do this then if you are all still up for it? Stefan
  4. Looking good, hats off to anyone who spend thier hard earned commissioning someone to make a pair of speakers for them. It's things like this at Scalford that make it worth going year on year.
  5. DIY compact, active floorstanders

    I'd be interested to see a raspberry pi based crossover, I've never seen any pi software that could hold the filters. Been a long while since I looked though.
  6. DIY compact, active floorstanders

    You are worrying unnecessarily the thing you want to really avoid is clipping at any point. Do you still need the preamp, you could just use the miniDSP as a preamp. I've used both of those drivers in an active 2 way in the past, apart from the obvious 2 way foot print it was as good as I've heard a 2 way. Stefan

    You need to experiment with room positioning and stuffing a little to get the bass right in your room. Ideally the cabinets should be back in the corners of the room and you should be listening at least 10 degrees off axis for the flattest response ( I normally cross them in front of me). Remove some of your stuffing. You'll find that less gives a deeper bass and more gives a tighter bass. They might lose a little bit in the bass compared to a dedicated bass driver but you should be able to achieve 35-40Hz in room no problem. Some do use a helper tweeter but IMHO that just messes up the cohesiveness of the speaker.
  8. Brilliant amps, I borrowed some from Mark for our KJFaudio room at the Northwest show, they certainly contributed to all the glowing reports the room got. Built like tanks too!

    That's interesting, where did you order them from? I should be the only UK place you can get them. Stefan
  10. Well it's been a good experiment. If nothing else you've learned that drivers only really work well in the size and type of enclosure they are designed to go into and even clever DSP can't change that. I'd guess they sounded better before the tweaks? You've probably already considered this but knocking up a little circuit to use with REW so can measure the TS parameters and model the cabinet behaviour of the drivers (or send them to me and I will) will pay dividends. Stefan
  11. They will.modulate each other and ultimately if you give them to much welly will kill each other. Measured distortion will be much higher. Still if it sounds good to your ears that's all good.
  12. Crossover Design

    Anyway, Linn have lent me these for a couple of months to join the party. We spoke at length at Scalford and one of the things that seems to hold folk back from doing an active conversion is the physical activity of actually doing it, both the maths bit and actually hacking thier beloved speakers, maybe down the line that is something I can offer on thier behalf so more people can actually enjoy the benefits of linear phase active speakers via a speaker they already love. Anyways this isn't a post punting for work, I'm absolutely not aligned with Linn, at least not for now, Danny sit back down😂 Over the next week or two I'll try and get these set up and see what we can accomplish. Some of you will have met the speakers I use day to day at Scalford in the past. They are already active but like Edd I've used convoluted (excuse pun) methods to accomplish that in the past. My music is all on PC and I use Jriver to hold all of my filters for the crossover. This then goes to a multichannel studio DAC and onward to my Hypex amps. The sound is excellent and I'm not really expecting an improvement there, but this method will certainly be MUCH more user friendly as Edd alluded to in the past. It looks quite pretty too. This has arrived in good time, both of my studio interfaces have broken and one of my Hypex channels is down! I also build and supply a few less speakers during the summer (what summer) so have a tiny bit more time. That said, don't expect really quick results from me😁 Thanks and Kudos to Linn for getting thier feet wet. Stefan
  13. Crossover Design

    Look what arrived this morning Linn Majik Exact ox and Linn Majic DSM Here is a close up, they look nice and understated. Oh, it wouldn't let me upload any more....Danny, consider adding auto smushing to images so the resize to 320px and get compressed automatically. Better for users, better for Google page speed results too 😀
  14. You've got the low bass side firing driver in the same space as the existing driver on the front? Don't do that it only really works of both drivers are identical so they are either doing g exactly the same thing or exactly the opposite thing. Stefan
  15. Frugal Horn XL Build

    Glad you are enjoying them. I've managed to get hold of 2 more pairs as well so hopefully a couple more customer can get the benefits. Stefan
