8030A with dual 7040A Sub

There are other discussions on this very topic, but i wanted to get one last consent on this config.

7040A extends down till 30hz but at max SPL they peak at 40hz till 85hz. I am going to keep 8030As very near, like 1.5 feet away, and keep dual 7040A below them, to create a perfect stereo speaker system.

Something like the image attached. Infact i will keep 8030s horizontal over the sub, peeking out from top of it.

Now i already have 8030A pair. But i am going to buy sub for the same. The only reason I don't want to go for 7350A is because of their size, i will rather buy one sub then. But if i go for 7040A, i may buy 2 and keep them on my table the way shown in the attached image.

I have few doubts, if any one can clarify me on that:

1. Will 2 subs (7040As) will be able to compensate for the fact that since they are dual, they might be able to produce 30hz at higher spl than a single 7040a?

2. If i am still better off buying 7350A rather than dual 7040As?

3, Are the frequencies below 30hz very imp that mixing with that range can cause mix issues? Thats why i should stick with 7350s?

My use case is composition, mixing etc in home studio environment. Partially treated room and I use sonarworks since my 8030As are not GLM compatible.

I mix at low volumes, like 40 db or below. Since the proximity of speakers is very short 1.5 feet from my listening position and 2 feet apart from each other, at low volumes, I am able to get rid of reflections to some level and get a very good image and clarity with my 8030s.

I am also inclined towards buying 8331 pair in future, just FYI since i might retire 8030s. But for now, with my current situation, what seems to be the best advice.

I am aware of all details and pros and cons of 7040A and 7350s. But since these days audition is difficult, I am just relying on forums and advice from experienced people here. Thanks for reading this.

0. mounting 8030 horizontally is not advised.

1. Yes, twice the acoustic energy, so +3db @ any frequency.

2. Good question. I'd urge u to get one 7350 now, one later since it's the lowest price to your desired setup.
​​​​​​​But there's one caveat, 7350 only has distributed bass management, does not filter output for the tops. we'd have to check if 8030 can filter input signal.
​​​​​​​Also digital speakers have small delay, about 80cm. I haven't tried such a setup, I don't think delay is a big problem.

3. You'll be okay unless trying to do high end mixing/mastering. But for that you need a more elite setup anyway.

thanks for your reply. Regarding your 8030A filtering input signal, it has a bass tilt switch for 85hz, is this what you are talking about in your point number 2 above? If so then i guess 7350 can work. Plz let me know.

Also, as suggested by you above for me to get a 7350 sub instead of 2 7040a, so i assume that later adding another 7350 to make it stereo sub is more advisable than dual 7040a today?

I think the reasons behind this should be a more suitable and powerful 7350A sub for 8030A rather than 2 smaller subs 7040a.

well, this is what happens when one has to buy stuff by reading threads on forms. But its still good if the end decision works out well.

Since your above reply came late, I anyways ordered 7040A to try out, if found inadequate, i will then replace it with 7350A rather.

So to sum up, dual subs are good, may be better, but sticking with 7350A (single or dual) for 8030s is advised & preferred rather than dual 7040A.

Ah, sorry i missed that.
​​​​​​​Not sure if the 85Hz bass tilt switch is adequate. Any Genelec staff around? ask by email support if necessary.
I urged you towrards 7350 because it's the cheaper than buying 7040, selling that, and then buying 7350.

And it's more sub for your money, 7040 is just a bit too lightweight to really be a sub in my book.
