  1. These things are very good, can operate happily from a 25w Passlabs clone amp with incredible micro detail especially from the Raven ribbon tweeter.
  2. Nice classics, would appear to be matrix version with ported bass enclosure. Recommend you include pics of the model label if still on back, covers off to show condition of drivers and perhaps dome tweeter being either fabric or metal to indicate model series. I had the mark 1 version 801F series with sealed bass enclosure and fabric tweeter, very good bass, 3 D imaging and voice detail. On par or better than many modern speakers, they put B&W on map of fame. GLWS
  3. Most modern 4 x 2 home plans are configured with family and dedicated HT audio rooms and older homes with extra room do also. The family audiophile can make use of the HT room.
  4. If you don’t sell soon you can store it in my audio room in Mount Lawley
  5. Ask the question in the specific forum topic for wider responses.
  6. I have heard of people with such problems on gumtree and get a few occasionally myself when advertising. In my experience they are easy to deal with: 1. Ignore them 2. report them 3. if deal proceeds make sure due diligence is done for both parties whatever it takes, call them and suss it out, get pictures of ID, use PayPal, if local meet them, make sure they have good seller review history etc. The suspicious ones are easy to pick out and you got be bit tough and savvy. However, I have had 3 bad experiences in 15 years loosing money and never hearing from them on two occasions, reported to Police but no action. A third one internationally, I tracked their name and forum identity down, threatened to call them out publicly on all the forums they existed on and shame them, which flushed them out after 12 months to refund. On the flip side there are lot of seemingly honest sellers and buyers who for various reasons are either hopeless responders, absent minded, don’t check their messages, inexperienced or don’t know anything about how to transact that are the reason for issues.
  7. It wasn’t as you mentioned. It was a long time ago, can’t remember exactly how I configured it but it was done from a recommended diagram of how to configure such amps in every possible way. The sound was never muddled or bad, just different and no better or less effective. I did this also with two other power amps, not integrated amps of another brand the same model and the same result. These two examples are not statically relevant so I wouldnt hang my hat on it and can easily believe your results.
  8. Despite my earlier comment, yes I agree if properly done it should make a difference but the OP is proposing to cobble together a basic combination and hope for the best. In my example cobbling together two NAD 3020 amps there was one mono blocked scenario that sounded more powerful than either single amp or the tweeter and woofer being fed separately, but the coherence wasn’t there.
  9. If this comparable I’ve done this using two NAD 3020 integrated amps with pre outs and main using Proac Response 2.5 speakers. It never got better than using one single integrated amp in terms of coherence and musicality. The sound changed with each configuration but never better, often worse.
  10. Picture of another Linn Kan MK1 crossover currently for sale on ebay Australia showing an extra 24 ohm resistor to my version. Looks like identifical crossover parts count, but the extra resistor looks to be where the tweeter circuit is located seems too high a value to be attenuating the tweeter, most likely shunted with the inductor.
  11. It’s completely different to the one I traced out in my model.
  12. Welcome, there’s a HT forum topic you could direct questions.
  13. Welcome, probably best to post questions in speaker forum section for wider attention and answers.
  14. Have you not got your own crossover circuit to unsolder the inductors and measure them with a suitable multimeter? There might have been at least 2 versions of them with different tweeters so the rest of the frequency response would likely be different if anyone have the inductor values.
  15. WC is where my best room modal bass response is, every bit helps
  16. Do you mean MBLs have an even narrower sweet spot, can’t see they would as they appear to be omnidirectional. The OP lives in New York and wider US states the home of incredible diverse and cheap used hifi market choices 15 x Aust population market.
  17. It’s true panel speakers have a narrower sweet spot than other types of speakers, but its completely functional and normal for any serious and concentrated listening in the prime seated position, it’s not like 1cm left or right head movement you lose it. My old Acoustat ESL pictured has a sweet spot about 10cm left right, better than a modern $30k Martin Logan in terms of the quality of imaging ability 3D effects. My Accoustats will work very well in a 2-3m listening triangle with jaw dropping imaging and voice coherence., very non fatiguing for long listening sessions. Even with other speakers none of them will stay within perfect image if one moves the head 20cm or so. People expecting a speaker to image equally within 1-2m left of right have an unrealistic expectation, it doesnt happen.
  18. On the contrary there are brands that specialise in designs or claim to achieve better imaging etc and those effects you mention, in addition to already said like B&W models with the skinny tweeter mounts and soccer ball midrange driver enclosures; time aligned front baffle, narrow front baffle surface, sloped or stepped drivers at surface (VAF, Eggleston, Duntech, Dunlavvy, Audio Physic etc). There are brands of speakers that specialise in flat baffles or toilet door size panels using large ribbons like your AMT tweeter, electrostatic panel membranes or hybrids of them with a woofer doing the low bass duties, such as Accoustat, Quad, Martin Logan, Soundlab, Magnapan, Newform etc. Many of these will out image and soundstage most conventional driver cone speaker designs and total disappear in a room. In US there are many used old Acoustats for around $500-2000 that were once many times that and still going strong as the electrostatic membrane coating is long lasting. The smaller models will work well on modest 50w amps, only down side is large size and playing loud levels. I have the model pictured it kills most mega speakers for imaging and soundstage.
  19. From generalisations and personal experience Is the experience I'm describing related to the ATM tweeters in the Tuks? If I’m referring to correct model pics of the speakers and drivers, ribbon tweeters can be different sounding to dome tweeters with forward imaging affects and very ethereal micro detailed. Would an external DAC further improve the experience or is that not worth the investment and just stick to what I have? It may do you’ll just have to try them out based on reviews initially and in your system. The differences can be very minimal between dacs, less so than swapping speakers that have more effect than other components particularly at the budget you have invested or likely to. As I grow into this hobby can others share speakers brands that are known for how well they image? Kef Ls50 and others are renowned for better than average imaging and detail effects. Comparing the Klipsch to the Tuks, is the soundstage capability of a speaker primarily driven by the quality of the speaker components or the components driving the speaker? One driver component design and build quality over another can have better soundstaging, but of equal or greater importance is the skill of the designer and the electronic crossover circuit inside the speaker diving frequencies between the woofer and tweeter and other aspects determining the final result, refer to speaker design web links for this on a range of variables too much and complicated to explain here.
  20. As mentioned the attenuators are L pads varying the resistance and dB levels to the drivers, that occurs in the crossover circuit of other speakers with set resistor values and levels. You simply adjust them to suit your tastes and room acoustics, while at the amp end the same, nothing complicated. If the sound is too sharp, reduce the attenuator levels to where you like it.
  21. Beautiful looks like decent chifi copy. If it sounds anything like my Chamila local built dual mono pass clone stellar detail and imaging for the right efficient speaker, tempted to get this for a shootout, GLWS
  22. Gumtree is also a big place to sella don’t be too afraid to package and send smaller items if you want to increase chances of best price and sales. Plenty of free packaging behind shops etc.
  23. A repairer might be able depending on the problem if it’s a burnt out dome wire coil resolder it. Contact B&W for prices, search internet for spare and service dealer etc.
  24. Brake bank term is a vague term, what is the max you want to spend on speakers, size of the room, type of speaker (stand mount, floor stander, 2 driver or 3 way design etc). For preamp maybe better to get stream device with preamp built in.
