  1. Question about device drivers. In the past, whenever I needed to clean up an older Windows PC to remove bloat and remnants of uninstalled applications, I always try to capture/download some Device Drivers before I do a fresh Windows OS install. I have the impression (maybe I have not looked hard enough) that only a minority of manufacturer's offer Linux drivers for their peripherals, sound cards etc. So, if you were to wipe your HDD and install Linux MINT, where would you get all the latest device drivers from? I note that, when posts appear in Windows forums about sound cards or other peripherals misbehaving, probably the most common advice is to "download the latest drivers" from the manufacturer's web site. So what would the equivalent advice be for a MINT user?
  2. This is what Microsoft itself says about data harvesting by Windows 10: “Examples of data we collect include your name, email address, preferences and interests; browsing, search and file history; phone call and SMS data; device configuration and sensor data; and application usage.” If an app harvests your personal data you can look for an alternative, block it or uninstall it. But if your operating system disrespects your privacy, you're basically a sitting duck. What business does an operating system have with tracking things like your personal browsing history, search history, your interests and phone calls? I will avoid upgrading to Windows 10 for as long as I can.
  3. Thanks for the input Snoopy, but it's not that complicated - he has bought a 5.1 Kef speaker set for HT. But, he also has a beloved pair of heavy, active 2-ways, one of which has bad electronics. So an active crossover will allow us to play around with to see if we can match the sound of the amp-less one with the good one before deciding how to proceed with those. Even though he lives far away, we look forward to the crossover fiddling. But this thread isn't to delve into his scenarios - as mentioned, I'm just keen to learn about the high/low filter features that may or may not exist on "typical", garden variety AV pre-pros to avoid having to download and read AV manufacturer's manuals.
  4. Could be right, but my understanding of the 2.1 feature of most low/mid priced pre-pros is that they: 1) usually output the subwoofer in mono, whereas the requirement is for stereo woofers 2) often limit the subwoofer cut-off frequency to something under 200Hz, whereas crossing to a woofer may need north of 800Hz. Know of any one that does subwoofers in stereo with choice of cutoff freq up to 1000Hz? Because I have offered to sort out some options for an elderly family member. It would be nice if he could cover home theatre and 2-channel with one box, and not need to hook up a PC to make adjustments as you do with miniDSP. I'm just checking in SNA's specialist AV forum to avoid having to read AV manufacturer's manuals. In my own system I don't use miniDSP but I do play with outboard crossovers using a 6-channel usb DAC and also some pro audio 3-way crossovers. I don't do HT. To Colin (cwt) - thanks for your informative post. That JBL Synthesis covers a lot of bases, even throwing in Dirac Live room correction; very impressive. Though at 6k in the US, it's Australian price is going to be well out of range for my man. I am a bit surprised that, apparently, one cannot do the low/high pass filters for a crossover with a garden variety AV Pre-Pro, given it already has a cpu, operating system and app software to handle more complex functions like parametric eq and surround decoding for DTS, ATMOS etc. So the hardware and software infrastructure is already all there, just needs an extra bit of application software to do simple high/low filters and route the outputs.
  5. An AV Pre-Pro is an AV preamp and surround processor, with pre-outs only (no power amp included like an AV receiver).
  6. I haven't owned a pre-pro. Is it possible to set up a typical av Pre-Pro to serve as a sort of active crossover? More specifically configure it to: 1) send two L-R main channels to woofers using e.g. a 24dB/oct low pass filter 2) send two L-R main channels to tweeters using e.g. a 24dB/oct high pass filter This to serve 2-channel delivery rather than full surround delivery. I know most pre-pro's allow you to set up parametric equalisation filters, but I don't know whether you can set up the far simpler low/high pass filters. Also you would need some routing configurability to send L-R mains to pre-out ports normally used for surrounds.
  7. Peter, just to clarify - are you saying here the tungsten hole saw works well to cut MDF and plywood, or hard stuff life bricks and bearers?
  8. Couldn't help noticing that these JBL 698 / 690's look similar to the layout of Klipsch floorstanders I've seen - similar waveguide size plus 2/3 woofers below. So the question arises - in what way (if any) do the Harman versions (JBL) differ from the Klipsch versions of this genre, if you pick models more or less in the same price range? And, is there a "house sound" in play at all? It's an invitation to expressing bias and/or subjective impressions, but please I'd like to hear them since I've never owner either brand and forum impressions are less conflicted than magazine editorials.
  9. Nice concise write-up of your project, Mark, covering many bases. Photos show the cabinets to be a high quality build and near complete so you may be pretty close to hooking up that D23. Following with interest, especially since the Ultraflex approach is rumoured to produce a distinct sound compared to conventional bass reflex ports.
  10. I have never owned B&W so am keen to understand what the "B&W sound" is - can you briefly elaborate please ? In respect of those woofers, if the crossover point from midrange to woofers is low (eg. under 300Hz), the wavelengths of bass frequencies are so long that I would guess the woofer positioning to be purely cosmetic.
  11. Also interested, and seems pretty much "unobtanium" in Aus at the moment. If I may add an ancillary question, just in case horn experts are lurking: what waveguide product/s could be considered to have close (or even ball park) similarity to the Seos12 and Seos15 flare shapes?
  12. Item: Q Acoustics 3050 Floorstanding Speakers Location: Sydney Price: 470 Item Condition: Used; no faults, unmarked Reason for selling: NLR (too large for current application; compact bookshelf more suitable) Payment Method: Pickup preferred, but may consider shipping (Cash, Paypal friend) Extra Info: Over one metre tall, dynamic and quite transparent sounding - fine combination. Does not fatigue me when listening long hours; high end is very clear but not aggressive. Just can't point to any weakness. Online reviews available; won a few Editor's Choice awards in Europe. Readily driven to good SPLs with modest amplification (60W /channel performs well) - beneficial if you prefer integrated amps or tubes. Unmarked with an understated walnut veneer that fits in readily with most decors. Preference for local pickup (Lane Cove area, Sydney metro), but still have the original boxes in half-good shape so could think of shipping, though insurance will be necessary. Pacific Hifi retails them in Australia for $1200 new, so the asking price is IMO very competitive. Photos: Advertisements without photos of the actual item will not be approved.
  13. Very interesting post covering a big range of speaker styles Doddsy. Good to read because you have no conflict of interest like the typical hifi magazine. Since you've had first hand listening experience to such a large range of quality speakers and you liked the sound of the LS50 so much, what do you think the step up in expenditure for a Neumann or Genelec monitor will give over the LS50? I have to admit to not having auditioned the latter so ask just out of pure interest. Especially given the "active" version of the LS50 and the Neumann/Genelec studio monitors have similar driver and cabinet sizes, what sonic benefits would the jump in money deliver?
  14. ACG, haven't been following threads about this build, but it appears that you built this horn hybrid by your own hand, and I must say, irrespective of the sonic angle, it is an exceptional effort and workmanship, especially considering how unforgiving a material steel is. Several black holes away from the logistics of having MDF panels cut at Bunnings and buying screws and glue. To me, it looks stunning, and will be even more so when adding the massive horn at the bottom with gaping mouth. Nice curved backbone; assume you can play around with vertical positions of the MR and HF horns. In all a confident beauty that exudes form-follows-function. Probably a project in itself just to play with crossover settings. I expect that to do the sound justice, you would want a "really big" room and I'd guess a minimum listening distance of say, 6m.
  15. Nice. That can be real hard work (hours and hours) winding a coil like that neatly by hand .. no? The relatively thick copper wire, 10AWG - did you choose that just to keep the DC resistance down, or does it have any effect on the final mH inductance value ?
