amazon - Only 2 left in stock.
EMINENCE DELTA 15 LFA is good for a VB = 373.4 L, FB = 23.5 Hz (92.1 dB/2.83V/m) not 100 or so.

I meant the EMINENCE DELTA 15 LFA is good for a TL speaker. (Not a 114 L sub.)

So, my current BR setup is not good for the eminence driver? Better to have a TL setup (with a folded horn, no?) That increases the dimensions of the speaker I guess (373 L )

Would the JBL 2226 work with a normal Bass Reflex enclosure? What volume?

PS, unfortunately, the horns can't be delivered in Belgium Thank you for the link anyway.

You can ask a speaker kit from Wayne Parham with the JBL 2226 or just the crossovers. You can also take advantage of the horns availability. Have fun.

How much volume should I need for the JBL 2226H speakers tuned at 40hz? (what about the ports?)
I might buy a pair of these speakers (used) for a nice price. But I have to decide today.
Will it be larger then my current setup?

Thank you!

Wayne Parham's Pi 4 Build Thread
A link, having in mind that Wayne P. is critical of derived copies of his speakers.
The JBL 2226H (from others posters opinions, never tested) it's a difficult design with smaller lower extension to play with subs. What size are your main speakers (if you intend to place them in your cabinet) ?

For now, I would stick with the original volume of my cabinets (because it is easy with the television furniture). They seem to have very similar dimensions of the 4pi speaker.

The dimensions of my main speakers are:

internal: 64cm * 44.5cm * 30cm

should that be possible with the 4pi setup?

But if the JBL 2226 doesn't fit in a cabinet with those dimensions, I'll go for a smaller cabinet (less large, taller) with 12 inch speakers.

It's because of the very good JBL 2226H deal that I am hesitating..

Doesn't your receiver have a room measuring device. Or it's just a stereo? I would say get them and work out the subs as a different project. The mic works out the crossover freq. in auto. mode.

you mean 'get the JBLS', right?

My receiver is just a stereo:

- preamp Kenwood C1
- electronic cross-over
- 2 solid brittish amps (HH VX300) used for broadcasting and television

But I can measure SPL curve with my sony mic and the program REW, that's no problem!
