Greets!

Note that the .....124171 has a revision 3 in the bottom R.H. corner and none on the other, so the correct one to use [assuming of course there's no newer revisions].

You're welcome!

Yes.

Nice driver! Loaded it in Hornresp and 40 L is 'right on the money' IF its published specs are reasonably accurate [no clue, no experience with the brand] and the big Xmax should make it an above average 'sub' if there's some decent room gain. I guess those early numbers were for mobile audio apps.

Yes i want them very much as it will be very suitable for a WAF (wifey only wants slim towers) But a pair of them will be expensive too.I already have SB34NRX75-6 on the left corner but i want to make a stereo one for better and homogenous response in living room.
I also have one Sony XSGSW121D 12" car sub and one B&W 12 inch subwoofer spare which have high qts.
What about different subwoofers with linkwitz transform and spl equalisation?
Or should i sell other subs and buy shallow ones?
And what do you think about SB34NRX75-6 sound quality vs shallow SB ones sound quality?Maybe i can buy one more of SB34NRX75-6 and make stereo tower.(But I can make max 60liters inside volume per box tower)
.Thanks again.Best regards

Again, no clue beyond its specs, build quality in pictures for this, and most other consumer brands, so based on these I prefer the RX75 since it has a lower Fs, Qts, much higher Vas, efficiency, which normally equates to relatively superior performance overall.

So, what's your set up, opinion of it?

That said, I wouldn't use either for 'subs' > [Fs*8] and [5] octaves for wide range [Fs*2^5], so for you it would depend on if this met your needs or someone with 'hands on' experience says otherwise.

As for the Sony, I ignore any brand that doesn't provide decent, accurate enough specs, so personally would use it for skeet practice if couldn't get my money out of it. A double barrel's worth of 12 ga #4 shot ought to make it 'boom' pretty good one time.

WRT sound quality of regular Vs shallow frames, mine is currently limited to the cheap mobile audio ones my neighbors use, i.e. no sound quality to these old ears, but hope to compare some better quality ones before I become too deaf to notice now that I know they exist.

Re LRT transforms, 'sub' driver quality; after having experienced what today's incredible DSP can do, I've lately been suggesting using any driver regardless of price that if once EQ'd will met the needs of the app, then forget its other specs and the few that have tried it have been very pleased.

Hi.The problem is only WAF.I also prefer SB34NRX75-6 in bigger boxes but i should make it slim towers.Outside dimensions should not exceed 23cm wide 35cm deep and 104cm high.So i should build sidefiring subs.
And for bracing what is the easiest way to do it?I am thinking to put about 6-8 pieces of 20x20cm square pieces vertically.I am not sure it will be enough.
Thanks and regards

The Wavecore's 6mm Xmax is good considering a 3" depth, but double or more that displacement is fairly common for 10" drivers, allowing 6 dB or more output. Below 40Hz, a 6 dB increase in level sounds more than twice as loud.
