Default 15 inch ambiance FR

Here is my latest speaker project. Took me quite some time! Love their effortless 3d sound. The 15 inch woofer is only there for the low midrange. To crossover from the lazy 12 inch powered subwoofer to the PHY-HP FR (unfiltered).

Jev, do you have any more info on your project? Very interesting. How did you come up with that arrangement and what are the crossover points? Great looking.

Thanks.

In the beginning of this project I set my requirements as follows:
Active subwoofers 12 inch as low as possible FS
Fullrange low-mid-high as possible but wanted linearity (used Lowther before which are too upfront)
Supertweeter support
Lots of dynamics in the sound
Alnico magnets for the most part of the spectrum
Not too tall
Not too wide
Depth was OK
Simple crossovers
Well the configuration is as follows:
Active sub XO around 80Hz (70L Wavecor Subwoofer SW312TU01)
JBL 2220A XO around 150Hz (16 ohms, 15 inch, alnico NOS, crossover with HQ58/15/112 15mh)
PHY-HP 8 inch silver coil (unfiltered)
Visaton TL16H XO around 10KHz (1.4 uF)
I wanted to have a lot of dynamic and ambiance in the low department hence the extra 15inch woofer which gives a 3D dimension to the soundstage and gives of very much power around 100Hz where the subwoofer and PHY-HP would not have enough energy (PHY-HP) or would be too slow (subwoofer with heavy cone).
The configuration I came to because of practical considerations for the width of the box. But in the end it was a gamble which I now feel turned out very well. I have no longer a need for new speakers because these have it all for me (sound staging, enough low, enough high, balanced sound)..
