I've never understood what 'High-end' means in matters of acoustics. There are many 'high-priced' components, some that are worth the money, many that are not, if we're to go down the route of $20,000 speaker cables for example, but high-end ... what the definition?
TransmissionLineDesigns it’s hyperbole and there is no definition, but the way I’m using it is cost no object quality and specifications, no expense has been spared in the design and construction of these drivers from materials to design and even aesthetics, and these drivers have the performance to back it up. Conversely a $20k speaker cable sounds the same as a $50 one, I don’t consider snake oil when I discuss audio products. Thanks!
@@javadshadzi4824 The question was suppose to be rhetorical rather than a dig! Don't get me wrong, I have morel drivers in my set up, and I used Morel in my car audio, however, ... at the end of the day, we all listen with subjective listening devices called; our ears. .. and acoustics don't really respond to parameters such as 'how much this widget costs'.

No worries I didn’t take it as a dig, everything I said applies, the term is useful and commonly used in the DIY speaker building community to describe what I clarified above.
@@javadshadzi4824 You may be right but there is some confusion about the real answer. Some manufactures define xmax using the formula of (Voice Coil Height minus Gap Height) divided by 2. This formula is supposed to show the excursion length in millimetres during which the voice coil is under full magnetic control within the magnetic field. Xmax is a magnetic field measurement so exceeding the xmax does not physical damage the speaker, exceeding xmax makes the tone loose and rumbley which is terrible for hi-fi but some bass guitar players like it - they tend to be the bass players who prefer big slow 15/18 inch speaker rather than the tight punchy 10 inch bass speakers. The above formula works well for underhung voice coils but the formula is misleading when applied to overhung voice coils which are most common in sub-woofer designs. Search google images for "voice coil geometry". Another complication is that some manufacturers quote their xmax figure with a "+/-" in front of the number, but some don't. It's necessary to closely read the manufacturers fine print to see which definition is being used. What I know from personal experience is that for bass guitar players with a low E string (40hz), they should not use speakers with less that xmax 4.5mm. Players using a low B string (30hz) should be looking for speakers with AT LEAST xmax 6mm, meaning 6mm in and 6mm out - so total cone excursion of 12mm when playing the lowest note (30hz) at full volume. Note: Volume (loudness) is created by wave AMPLITUDE and the amplitude is generated by the physical length of speaker cone excursion so the limit of speaker xmax is only reached when playing at full rated speaker wattage, i.e. low AND loud.
@@dreamdiction I’m not aware of any broad or wide spread confusion about the definition of Xmax, it’s a well defined parameter and you stated the formula for it correctly. It signifies the amount of excursion, in each direction, where the voice oil is in the magnetic gap, outside of Xmax the voice oil begins to leave the magnetic control of the magnet. It is always recommended to use any driver w/in its Xmax for the lowest distortion and best safe performance. Xmech is the rating where the voicecoil can be damaged in one way excursion.
@@javadshadzi4824 there are indeed many definitions of xmax. I've seen it defined as: 1) Gap difference/2 2) Gap difference/2 + 1/3 coil length 3) 70% BL curve 4) 10% distortion point Etc etc.
I have been very curious about the Morel drivers. Glad to see a project with them. Thanks for the great videos.
Morel are a great brand, and they produce some great products.
@@juststuff5216 Morel are very good drivers ,made in Israel.
Very cool, glad morel builds are being used instead of people hating on them and recommending Dayton audio lol
Yep maybe next year I start my build lucky for me my mate used to work for JBL so am good he says 😊 only thing is there going to cost maybe 2k
Nice project! Can you post a video of the finished product? That would be amazing!
That woofer👍👍 Should be a great project - looking forward to how the baffle looks.
Wenge is used on German Warwick bass necks and finger boards.
These drivers are specifically designed for home audio or can be used for automotive.
Cool
Javad- Could you please give us an update on this project? Thank you.

@@javadshadzi4824 I'm bias .. DIY rules in my book. Good to see someone who really knows what they're doing and is passionate about what they do.
Say WenG-ay like ray may, not like an edge wedge on a ledge
The 10.5mm xmax is 5.25 in and 5.25 out. That is my understanding xmax ?
Xmax is one way, each direction
