Suitable Enclosure for TB W5 1611 SAF

Hello World
I decided not to follow my own advice and purchased these off a local speaker builder who made me an offer too good to refuse. I must say I was underwhelmed initially but after experimenting with larger baffles and giving them a day or two to break in. they sound very smooth, phase coherent and convince me there is is something to this full range driver stuff. The build quality is excellent for the money. 60 Hz FS is a bit high but you can't have it all for this money. They do have a certain coloration due to the polypropolene cone. I do prefer the sound of a good paper cone because I like that coloration better. Over all I am not sorry at all that I purchased these. Looking for advice for a cabinet or Horn to suit them. I already have a hybrid TL cab design that I know will work well with the modified lower QTS due to the neodymium backing magnets that sweeten the treble. If there is anyone out there who has put these into a front loaded horn I would love to hear from you. The Le Cleach Azura really appeals to me and I like the http://www.hornlautsprecher.de/ website but haven't got a handle on the theory as yet. Has anyone out there built a horn for these and what are their opinions?
Cheers and many thanks. Mark
 
FS=60Hz is actually not all that high for a 5" FR IMO. Efficiency would be like to quickly plummet from the nice figure of 90dB had they tried to extract more bass out of it.

I have to admit to a certain bias against poly-cones myself, but this is a driver I'd like to hear/try in any case.

I'm afraid it's not an ideal candidate for a front-horn, it lacks motor strength and an oft-associated rising response and hot treble area that will naturally balance the horn transfer function. Electrical EQ can always be used though, but this can quickly eat-up power headroom, especially on larger horns, if one is to have any usable bandwidth. It'd be wise to test that out with rigid cardboard or foamcore build before plunking down for what is like to be a costly horn.
 
Hi all
I apologize for my wording. What I am itching to build is a back loaded horn that exits to the front. Apologies as I am new to horns. So far the drivers have been broken in in a 4.5 litre sealed enclosure with a 350mm X 470mm high stiff cardboard baffle and sound amazingly good. Can't wait to put. them in a proper enclosure. The top end is lovely with the neodymium backing magnets. Without them the sound is a little dull on top. I don't find it too bright up top as long as you have a baffle wide enough to mitigate excessive rising response. This driver can be used without correction circuits and has to be the best value for the quality & performance. Definitely sound better after 60 or more hours run in.
Cheers
 
I've read pretty conflicting opinions of the 1611's sound, with arguments often based on the cone material. I don't know how much listening time you clocked in on these in your FH3, but how did they do in the midrange/treble region? How beamy were they on top?

I did not have issues with beaming -- the top was a bit soft. They have a plasticy coloration i did not like. It was not severe. EnABLing the driver helped a bit to hide that but did not completely eiminate it.

Hi Planet 10
The more I look at it the more I like the idea of a fonken for this driver. Your suggestions on the optimum version to play with my 14w rms CV40/60 parallel SE triode with variable feedback is most welcome. Just remember QTS with the 3 neodymium backing magnets is now closer to .33 and efficiency is 91.5 dB Try this to de -plastcise the sonic signature. Sounding better & better as they loosen up.
Kindest regards Mark.

They beam like crazy, but the sound is also that good, it has some vortex emotion of intimacy, can't explain it 🙂

PS: have you seen, there is a new paper cone version, didn't heard them yet, but they are on top of my list
TangBand W5-2106 Wide range speaker | DIY
crap now TB has new widerangers in all sizes money money aaaaaaaaaaaaaaaaaaaaaaaa 😀
TangBand W5-2143 | DIY

I find the W4-1320SIF to beam a lot too, but very good sound as well. I wonder if and when these new TB's will make it to NA sellers.
 
Hi all
Thankyou for hijacking my post to discuss drivers I don't have or care about. A special thankyou to "I'm sorry I can't do that" Dave. Who after I show Interest in one of his Planet10 commercial designs cannot even give me the simple common coutesy of a reply. Thank you to the one reply that actuually addressed my questions.
I thank you for helping me evolve to a higher level of conciousness that leaves most of you far far behind.
BYE
 
Hi all
Thankyou for hijacking my post.

AudioPath, look at the Tabaq TL thread here in the fullrange forum. There are dimensions for what is referred to as a Tabaq Large. It is a decent looking floor stander, and from what I read, the folks that built them to use their 5" Tang Band drivers, said they sounded pretty impressive. Hope this helps!

That sounds like a swipe. Life can get busy.

I did work out a miniOnken for these (the neo version). If you have changed the driver parameters i'd have to start over again with good T/S numbers.

Hi All

PTS Disorder says HI! Apologies Dave. The last post is exactly what I needed to hear. So I will stick with the design I have because of the altered parameters which essentially means no calculated enclosure for the standard TB will work properly for me. A quick A/B with my 2 ways tells me I will want a super tweeter as the highs are still a little too dull for me. I have a spare pair of the Peerless 810921, now known as the ScanSpeak Discovery D2608/913000that are a perfect match regarding efficiency. I will stick with the box I have designed and send photos of my speakers when finished. Just got to decide on the best crossover point. between 7 & 10kHz. Thinking that a large sealed cab using the natural roll off to a plate amped pair of 8 inch drivers for bass each channel Cabs are finished & ready to roll to enjoy the benifits of the linear phase and lack of crossover issues and live with the beaming while enjoying kick *** bass and extended treble. On vocals they are very good.
 
Thanks to all for your replies.
The guy who sold them to me wanted them back so I gained the experience and it cost me nothing. I think I would be happier with the larger Tang Band's AKA W8 1772. If anyone has any suggestions that can outperform this driver at the current Parts Express price of $174 each with the same efficiency I am all ears
Cheers Mark

That is quite a call on paper at least. Tang Band W8 1772 Neodymium magnet, Cast alloy frame 95 dB efficiency copper coated alloy Phase plug. lightweight bamboo pulp cone around 10 grams.
Versus Mark Audio 10 X? Both A & P vary from 87-89.5 dB efficiency Plastic frame, ferrite magnet and all the money seems according to their ads to be put into the cone & suspension that does weigh around 5 grams with a BL of 4.74 vs 7.1 for the TB.
With the PE price of $174 for the TB & $110 for the MA Alpair the opposite seems true.
for $50 more you get way more efficiency magnet technology SD or cone area cast vs plastic frame?.............................................................................................................................................................................................................................?
PLEASE EXPLAIN!
 
Some manufacturers channel most of their efforts and resources into things that will have the largest influence, like cone specifications, voice-coil configs, magnet, suspension, surrounds, etc. etc. I don't know exactly, but comparing different drivers, other bits seem to be "sacrificed" in order for these to be done well under a budget. That means they can make their drivers sound good, but make it slightly more affordable.

Other manufacturers probably went the extra mile. Things like using cast metal frames (which may be carefully shaped to further reduce vibrations, and also allow better breathing), exotic phase plugs, special magnet arrangements/material, microscopically tuned everything, etc. etc. Manufacturers expect these small improvements done everywhere would compound together to make more noticeable improvements. Of course, prices would then go up.

It would probably be an engineering decision by MA to go the first route for most of their product line. Even the Alpair 12 8 inch is cheaper than the W8.
