Yep use modern drivers and don't have a ugly speaker.Performance has a price
a 15 inch is a 15 inch you still don't understand, there is no replacement for displacement, and those are all modern driversYep use modern drivers and don't have a ugly speaker.
Displacement is not just cone area but also excursion, which modern drivers allow more of (although cone area quite easily overwhelms gains in linear excursion)a 15 inch is a 15 inch you still don't understand, there is no replacement for displacement, and those are all modern drivers
People who speak against 15" or larger have not witnessed a 15" or larger playing.
You can get 20 Hz from 4", but it's -20 dB below 1 kHz and over excursion happens at 85 dB. With dual 15" per side you can expect 90+ dB with 1 Watt and capacity that does not give in. 15" can have 15 mm xmax too.
My only advice to people, who think 6 inch is good, is to compare it with proper diy 15" side by side in the same room. Be it measurements and/or just listening, you will notice a different in favor of the larger driver. Bonus task: add high-pass filter at 50 Hz to both small and large speaker and listen yourself how the larger speaker will blow the smaller one away in both extension and spl.
After posting this, those who were wrong will come and cry about not saying that 15" is worse.
I've never seen anyone "speaking against 15'" or saying a 6inch compares to a 15", who exactly are you referring to?People who speak against 15" or larger have not witnessed a 15" or larger playing.

Nobody speaks against 15" - you speak against smaller drivers.People who speak against 15" or larger have not witnessed a 15" or larger playing.
What a tidy solution... very nice.This is my DIY solution.
Not perfect but acceptable for every day use.
Yeah, it's certainly not cheaper, especially once you get the bug for it. End's up just as bad as chasing factory Hi-fi cost wise. It is a really fun hobby though.Short answer: No.
Longer Answer. DIY speakers should be something you consider because you want to build speakers. Trying to save money is almost certainly a fool's errand unless you value your time at less than zero. IF you already have a fully equipped woodworking shop AND are highly skilled, AND have 2-3+ years of unallocated hobby time that you can dedicate to the undertaking, then you can possibly aspire to creating something on par with Revel etc. Maybe. But, you don't get to demo the speakers before you start, and there are no 'end game' DIY designs that I'm aware of that have anything more than basic measurements available - so there's a very real risk that you spend years pursuing the project and don't like the result.
Having said all that, the best 'end game' design that I'm aware of that has extensive documentation and build logs available is Jon Marsh's 'Wavecore Ardent' design over on HTGuide. It's a design similar to an Avalon speaker (Jon Marsh knew Charles Hansen before he got started in the industry, apparently) I believe the DIY cost was approx $5k, and would be a design that would compete with the F328BE and similar tier speakers. There are other expensive designs out there (e.g. Troels Gravsen) but none leave me with the feeling that they have a similar amount of design behind them.
Another that may be worth looking at is the 'Open Source Monkey Coffin' design from DIYAudio. I haven't looked into that as deeply, but it does appear to have had a LOT of design debate and seems to be a well-executed 3-way waveguide design.
The final point is that 'end game' speakers are as much about aesthetics as they are about sound. Finding one that looks good enough to motivate you might be tricky.
which scanspeak bass driver is this please . I have similar ideas to this . Nice to see somebody actually doing it not just day dreaming about it ha@MKR You ask for the best - here it is.
Tweeter - Bliesma T25B
Midrange - Bliesma M74B
LF - Purify. But I use mostly Scan Speak or SB Acoustics/Satori, Purify is REALLY expensive. For a 2 way they are the way to go, in my concept the benefit is small.
Sub - Whatever fits the need! SB34NRXL75-8 is nice.
Did you ever listened to big ATC or PMC speakers? These 3" domes have some magic with them and produce enorm SPL level. My goal is to achive something similar but with the best material available. This Beryllium tweeter is my goto for high frequencies at the moment - prefere it over ribbon or AMT.
But when you really need huge SPL levels you need to step up from the classic 1" tweeter - e.g. T34B.
The whole thing would be driven by a DSP based plate amplifier - I often use Hypex. With the digital input you save a lot of converting, sounds excellent.
Here is a detail picture of my actual setup. T25B, 2x 2,5" Satori Midrange with modified front plate, 2x ScanSpeak 20cm drivers. The midranges get updated to 1x M74B as soon as I have time. LF drivers are positioned close to the position needed for a single bass array - works well <80Hz. No sub needed in my small room but I will go to 10 or 12" in my next build just to get more headroom.

The room is for mixing and mastering and listening in near filed. It looks simpel but evey little piece of surface and absorption is optimised, even the table and slanted outboard are matched to the distance to the speakers etc.

What you get is sound as detailed as my K812 headphones. I never heard other speakers to be able to do that. But it's way more fun as headphones ;-)
For causual listening this room is way to dampened and you would need a different setup - but that's one way to go "End Game".
p.s.: You will never achieve the precision and details with a compression driver + horn what you get from these beryllium membranes. But you get directivity and insane dynamics - depending on the room and your listening this can be more important.
For me "End Game" means to hear EVERYTHING the source can offer - the system above can do so.
