Tang Band 2145 in action
That wide band single driver speakers work much better as a three way?
~~~~~~~~~~~~~~~~~~~~~ WEll , lets tag what I have **designed* ,,as Adam said ot if, pre new add ons,, **The Frankenstein** Which pretty much is what IT is. hehe ..so yeah its some sort of hybrid xover/WBer combo W18E001's/87db + Paper tweeter/91db + WBer 8/92db + Wber4/91db. Had my tech geek NOT stood at the doorway, and showed no signs of being impressed with my new all Mundorf xovers for the Thors.. I may not ever have embarked upon this WBer adventure/experiement/testing. Its a evolution, it evolved, its near finsihed,,just have to swap out the paper tweet fora Beryllium Neo dymium magnet tweeter from DavidLouis. 2 way as in xover type+ WBer type. 3 way Midwoofers + dual WB;'s + tweeter = 3 way. Adding the 4 result in stunning soudstage gains. Dang thing was just 1 month from heading over seas as a gift to relatives who can't afford such speakers...I'll give them the 6 which I can 't even give away on ebay. The 4 and 6 made in same plant in china,,but the 4 has superior mids tighter bass and equal highs. Same magnet, same cone material. The 6 just did not mesh with the 8. The only way you can match a 4 and 8 is if the 2 have near identical mids. Otherwise it will not work. The 6;'s slightly stressed mids, lowered the overall fidelity from the 8. The mids of the 4 and 8 are what we call in tube lingo *matched pair* Other option is TBB2145 + TB2141, alottt less cash and near idetical results. I said *near*, IMHO DL gets the Gold in mids, mids in the TB Goldsilver |
I understand NOW, why the aded 4 DavidLouis has opened up the fidelity in my speaker system...GOT IT... of course around here in this anti-wide band club,,no one is in the least bit interested as to *the why**,,and for that neglect, disdain,,I ain't about to give up the goods... Nice day. The Wide Band Geek Diana Krall, When I Look into Your Eyes cd, never sounded so ,,magical, so stunning, rich, accurate soundstage. Now Diana has become vividly real |
don't like t he looks of either The only TB I would consider putting up against the DaviDlouis 4 is the TB w3 2178 Most likely I will order that speaker,, $260/pair,,waiting for a holiday sale,,if not in jan/feb i'll order a pair but really I doubt its going to match the DavidLouis in mids. Then again...it might... btw this DL4 is now out of stock and who knows when back in production,,if ever,,all because of a EU source not making that tiny 3 inch cone... music starts at 6:35 92db, TB's W3 at 88db...I'd much prefer the 92db. To match the DLVX8's 92db. Synergy. https://www.youtube.com/watch?v=BgWR6IbqOOg&t=317s |
scratch the Tang Band w32178 Its Tang band W31878 I'd like to snag a pair at $200, but if I gotta pay the piper's 260,,I;'m willing. Those lil guys have been out for som time now,,I think years ago the price was under $100,, my guess is when Tang band figures out the true value of each model, the prices go either down or up. In this case a nice 50% increase. I love Neo Dymium magnets,, but in this model,, TB employs those round *pills*, Like Voxativ. Its a cheap way of employing highest quality magnets. The tiny pills in the Voxativ was too weak, rendering the Voxativ AC1A a dud, a complete bomb. In this TB case,, its only a 2- 3 inch cone, and magnet structure looks more than adequate. DavidLouis employs a huge neo dymium manget for its 4 inch.(3 inch acutal cone). IMHO the DaviDlouis 4 is the finest W4 on the market. Its no longer in production and seller has no clue when it will be back. Now he lists a cheap 5 inch that looks like worthless trash. |
acresverde253 posts10-11-2021 9:33pm@mozartfan BTW, I watched your YT video where you were using RG's bread board SET amp to drive the David Louis WBs. Be advised that the powertube used is the 50 tube and not the 250 tube (is there even such a thing???) and the amp uses two (2) of them. You might consider making that correction. ~~~~~~~~~~~~~~~~ Yes correct at his shop on tuesday,,, he did say **The 50 tube**, and forgot to have him clarify that, = Not 250 tube. Thanks SETs are not wimpy,, RG employs a colbalt in the out trans. Small but super powerful and not cheap. That SET has equal the big Defy's power + bass slam. I do not understand much dif in output froma SET vs a PP. AS far as employing a higher sens speaker is concerned. I note there are other WBers with a 94++ db sens. No way I'd be interested in anything about my 92 dbsens. Actually 90/91db is ideal. The DLVX8 is 92db the DLW4 states 91db. I can note a difference in the 1 db sens The DLW4 highs are definetly rolled off, say 10khz, (??) , but has quick tight bass kick maybe 80hzish,,, you;d be surprised at the lil punch in bass. . Mids are accurate/clean The VX8 has at least 45hz bass, if not the 40hz as claimed on the specs. Highs are there, whether its 12khz or 12khz+, I do not know, and am not at all interested where the roll off begins. You can hear the snares with sparkles. Miles Davis via DavidLouis. https://www.youtube.com/watch?v=xcjYiZztHgM |
at least in my speaker demos, I give you some ideas how the speaker actually performs, LIVE, vs your comp speaker rendition. I wouldn't lie by the way. Nothing snakeoil, fake comments, no pumping. Straight up. I've read enough comments on the 2 most popular brands right now to know to keep it real. btw I am not going with the Tang Band3 1878 as the 3rd wide bander in my 2 way WBer system. No, I rethought it through,,,thankfully i did not order the TB 1878. Fora few bucks more I can get the 'DaviDlouis VX6 I looked over Teks and Zu's, Both offer multi criver systems. So I figured if these 2 super hot labs (more folks are buying Teks and Zu's at the moment that any other speakers) If these 2 big time labs are making multi driver speakers why can't I. ?? anyone? That purchase will have to wait til I get out of the wide band experiementation debt. And after i buy a 845 amplifer. Hang in there, Either the DLW4 will stay or the DLVX6 will take its place. My system could bea 3 way WBer or a 2 way WBer. Its anyones guess at this point. Hang in there new developements are in the plans. Just need some audio cash. |
Yeah well if you want to finance my YT speaker Project demo, for a superior cam please gofundme The sony cam is all I could afford and does present my demo as trans radio. But again, if you hear Enrique Caruso sing in the Rome Opera House and he also sings in your bath with door closed are you going to tell me you will not recognize Caruso's voice from your shower? As the same cantor as in Rome's Opera house? All I am doing is givinga basic hint at how my speaker system performs. If there were any weaknesses I'd sure let everyone know. For my CM its perfection. btw the DLVX8 is NOT 92db as stated it is ~~95db~~~ right there with the AER/Vox But the higher up the sens ladder you go, less solid punchy bass. AER has like 96 db sens which is wayyyy too high for my use. 95db sens is the ultimate limit you want in a speaker Sorry AER/Vox I must be truthful here. which reminds me , time for another comment on the Voxativ AC1A. Sounded like the old transistor radios we used to buy back in the early 60’s, they were like $5.99. w ear plugs. Thats the way I would describe the performance of the VOXATIV AC1A with Neo Dymium Magnet motor. AC1A @ $1900/pair Obviously not recomended for hifi. 2 big thumbs down. |
Its compressed, for sure, my tech says its ridiculous to try convince folks of a sound they really can;’t hear up live. well I told him, if Enriqo Caruso sang at the Rome Opera House, and then sang same arias in his shower, door closed, Are you going to tell me you will not recognize Caruso;s voice in your shower as same guy at the opera house?? I am making adjustments/tweaks/mods to the configuration. Everyone just hang tight til i find some cash to finish the design. Just glad i held off on the Tang Band W3 1878, as the DavidLouis VX6 might be, in fact most likely will be the finishing touch. ’Not to say we can’t add in the TB1878 next year when more cash is avaliable. Might keet the DLW4 along with the TBBW3,, but hunch says, only 1 will stay, and my guess is the TB1878 will beat out the DLW4. The DLVX6 looks likea winner. I studied the driver’s pics very closely for about 2 hours. I know what i see. Just hang in there next year Frankenstein will live. Could be a 6-7 driver per channel speaker. Just crazy. A real monster just like Frankenstein. He’s going looking for Wilson’s top dawg for a shootout. You know the model, the one Wilson makes for the Dubai Oil sheiks **You mean the $950G speaker?* Yep thats the one. 6+ drivers vs 6+ drivers. I'm giving Mr Wilson the Jadis JA800, I;m taking my tech's modded Dynaco ST70 EL34 Giving Mr Wilson everything he needs to get his mega monster to sing top form. Monsta vs monsta. My system will have 3 separate cabinets, all combined under 100 lbs. vs the Wilson monster at 300+ lbs. David vs Goliath |
Ok you could very well make a system with dual tang bands, 2145 + 1878 and end up with close to same results as in this dual davidLouis Pity the sound in this vid is severly compromise. These WBers bring this legendary concert to a near real experience. Its that good. anyhoot here goes, Mahvishnu Orchestra Live CP 1973 https://www.youtube.com/watch?v=IdggD3H8F2A |
And no, even Mr Carlson with his Star Trek looking gadget test room , would convince me of what I assume to be true That Midwoofers don't do so well above 1800hz and tweeters start to break up below say 3khz. Especially on highly complex passges of symphonic orchestra. Thats a substantial range, critical, 1800hz - 3khz. Thick with grueling midrange complexities. Here is where WBers shine. |
For some reason this Live Mahvishnu did not record very well. I was trying to get Billy Cobham drums on the vid. the whole things sounds low fi. Soory about that...any hoot, so I was looking for some 8uf caps to ship off to a friend overseas with the paper tweets i was dumping,, + He gets the Davidlouis yellow cone W6 WBer, which i can't sell on ebay,,,and while looking through my stash of caps all taken from the Millennium xover, I saw soem 8ufs EVO's Silvergold. I looked at a fq/uf cap chart for tweeters, 8uf takes it down to like 5khz. I figured let me try a 8 uf, see how it performs on the paper tweeer. Much much better, The Mundorf SESGo 2.2 was chopping the tweeter off at 10jhz. maiking the tweeter restricive/compressed/dull. The 8uf opened the paper tweeter. Now the soundstage has taken on more ambience, more sheen. Can't believe small tweaks can make a huge pop in sonic gains. I'm expecting the Davidlouis' clone of the Scanspeak's Be/Nd tweeter to offer stunning resolution. Taking The Speaker Project one step closer. That is set for march/april. WBers absoluetly must have a tweeter of your choice. Either a 8 uf or 10uf are the ideal values. 6uf kicks in the tweeter too high fq, 13uf takes the tweeter too low. Tweeters begin to show stress under say 4khz. Besides the dual WBers have plenty of fq's at the 4khz range. Dont need the tweet to go lower than 5khz. |
