I've corresponded with Tang Band and they were prompt and helpful in responding. Thanks for another great video!
I wish I had watched this great video 2 weeks ago. I just bought two 10 inch woofers for an open baffle project. The Xmax is 6.5. I'm thinking about returning them.
I appreciate your style very much. Pretty much my favorite DIYer on CZcams
Very well made video. Thanks.
Thanks Marius. Great advice!
Great information. Thanks
Again straight to the point and clear. +++++
Great information , thanks.
Xmax is important, but Xmech is also important imo. Unfortunately not many manufacturers provides this specification.
Also, you need to be careful when looking at the sensitivity. Depending on how they measure it can change drastically. If they use 1W instead of 2.83V of if they measure it at 0.5m instead of 1m can change the sensitivity by a considerable amount!
Good informative video! I always watch for the SPL scale and smoothing, but wasn't aware manufacturers use different baffles and box sizes. I always assumed they all used an 'infinite' baffle. I'll keep this in mind next time I'm selecting drivers for a project.
Maybe it is a topic for a separate Video, but the TS-parameters are very important for woofers and should be mentioned. It can tell a lot if that driver is usable for what you want to build or not.
so good, thanks
Great Video 😃
Like your style.
I’ve subscribed to a class of yours and it’s great. Thanks so much.
What would be amazing is if you could possibly tell us how we can ‘ upgrade’ woofers in our current speakers.
Not how to build the xo, but to see if the cabinet we have can accommodate other woofers.
Instead of choosing drivers and then making a box around them, can we figure out if we have let’s say an MTM design with 6.5” woofers , what can we swap them out for, without the box not being able to accommodate them.
Thanks !
Great advice ill remember for next build. Btw, i use your simple 2 tool tower build as a reference for i just happened to have purchased the same woofers some time ago.🤓
Funny seeing you talk about Scanspeak drivers. In 98 or 99 I bought a woofer driver from them for a speaker I wanted to make, but never did. I still have it in my attic anf want to try to make a subwoofer with it. I'm not sure exactly which it is, but I remember it needed an absolutely immense box to go deep.
Use your attic as the box! This kind of thing, building speakers into the house structure, was done in the 1930s to 1950s when amplifiers were low-powered, 5 to 10 watts.
Nice video, as always, I was wondering if you can uncover some of the mysteries of determining the right volume of a box, and type, from the T/S driver parameters
I like most comments. And I agree with the x-max comments but I wonder whether the 26W/8534G is a good example of a low x-max problem. Perhaps it’s more an alignment problem. It’s TSP would better suit a sealed box; say around 50L or less. The BR reflex box needs to be large like 100L with a low tuning. Two of them need even a larger box.
great video - as ususal- I wonder if you can shed some light on the following issue: There are some speaker drivers (usualy the expensive once) that just tend to sound very clear fast more open and dynamic, as oppose to (cheaper drivers) that sound compressed and less "live" - can you point to the t/s parameters that "show" this capability of speed, clearity and dynemics. Thanks
One thing I can tell you that set's apart a higher end driver is the presence of a shorting ring in the motor structure. This reduces distortion and also it reduces Le. So, if it's not mentioned directly in the description, low Le is an indicator of a good speaker.
Correct me if I'm wrong, but some tweeter spec sheets feature a 2600Hz 1st order HPF following IEC268-5 standards. This would mean that if you want to use the minimum phase response (the one from the FRD graphs), you have to take into account this high-pass filter capacitor.
I thought 1st order filters do not mess with phase. But I could be completely wrong here
I've also seen xmax listed as one-way and as peak to peak
That's what I wanted to say, but I find it odd that it's rarely listed at all whether it's one way or p-p, or maybe that's just the drivers I'm looking at?
How can I measure XMax in my 6 1/2”? I am doing my first steps I. tS parameters measurements and I do not have any date from the manufacturer. Thank you!
What job are you doing?
Any audio related jobs?
Not really. I'm an accountant 😅
A well made speaker can have a lower xmax and sound better than a poorly designed speaker with a higher xmax.
tang band is notorious for fiddeling with parameters. ±20% is normal
Thanks for the video ;)
