as far as I know, Genelec 1032a is flush mountable. and have a exclusive flush mount accesary kit for 1032a.
and most car audio speaker is flush mountable. but they are not studio monitor speaker but hifi speaker.
If there was a car audio speaker for using studio monitoring. I would like to flush them into my room wall

anyway, could i find soffit mountable speker list in google or this site?


p.s genelec 1032a also need Diy filter for flush mount? or can built-in bass tilt switch be substituted for Diy filter?

Hi, it's been a while since you posted - welcome back

Sorry, but our original speaker guy hasn't had time to post here in a LONG time and I've been sorta filling in - no, there isn't a list of flush mountable speakers here. Basically, if a speaker has a flat front on the cabinet it can be flush mounted - it is more tricky if the speaker has some "different" design like the Adam speakers with their odd angles on top, or the newer Genelecs with their very rounded cabinets.

IF a speaker has built in amplifiers, John's soffit design using an air passage will let them cool enough - we have a few members who have soffited their Mackie 824's successfully and LOVE them. Also, rear ported designs should not be a problem - the idea of the port is to enhance bass, so if you soffit these speakers it may work out that you don't need ANY step compensation, since soffiting increases apparent bass and enclosing the box (and port) would REDUCE the bass, for a (maybe) net zero difference.

For a bit more on this subject (including John's drawing), you can re-read the sticky's at the top of this forum... Steve

thank you knightfly. you exactly know what i want to know and good explaination:D
it's very helpful information...
I found that SAT 12 speaker has a built-in filter for compensating boosted frequency derived from speaker soffit mounting.
but they don't recommand flush mounting subwoofer.
Do other brands also not recommand flush mounting subwoofer?

anyway, the following is the reply from Blue sky Inc. their service is really nice. and Pascal also good man.

Thank you for contacting Blue Sky International and for your interest in our products.

Below are the answers to your questions:

1) Mounting Blue Sky SATs in a baffle wall: Yes, this is possible, however you will probably need re-eq the mid to low frequency response of the SATs, to compensate for the boost in efficiency from the baffle wall. The SAT 12 includes this "baffle compensation EQ", the rest of our SATs currently do not. One additional consideration for the SAT 12, SAT 6.5 and SAT 5, is that you must provide proper cooling to the back of the speaker, to ensure proper operation of the amplifier and electronics. Consult all local safety and building codes, to ensure you are not violating any local regulations.

2) Mounting Blue Sky Subwoofers in a baffle wall: In general we don't recommend that you place a subwoofer in a baffle wall, because it limits your flexibility with regard to optimizing subwoofer placement. For more information follow the links below:

3) Will acoustic treatment improve the performance of Blue Sky studio monitors: Yes. A properly designed and treated studio can improve the performance of any studio monitoring system. For more information follow the links below:

I agree 100% with Pascal - I think there are a few people in the world that could ACCURATELY tell you WHERE in a wall to mount a sub for best sound, but I'm not one of them - apparently, neither is Floyd Toole, one of the main people at Harmon Kardon/JBL, because he also doesn't recommend subs being mounted in the wall for the same reasons.

If space is the reason you want to do this, one possible way I'd consider is to first build your soffits and mount the mains (first check my thread "are my speakers in a null" in the Acoustics forum, and use that info to figure out best placement of your speakers (assume that there are no soffits for this, find best theoretical placement of speakers in your room, THEN build the soffits around your speakers)

Then, once the soffits and mains are in place, put your subwoofer IN YOUR CHAIR but elevated to EAR height (NOT at 50% of the ceiling height) and move an omni-directional mic around the walls while using an MLS test signal (see the ETF site, here)

If/when you find a location along the wall that gives a good balance (smooth frequency response at subwoofer frequencies) I would think it would be safe to cut a hole there and install the sub. Keep in mind though, that if you do that and later want to move your setup, the sub's location may no longer be ideal... Steve

I'm not sure you would need or want to soffit a sub.

Subs are already located on the floor to take advantage of the 6db boost from the floor/baffle. They can also get additional boost from corners, and even more if it's located near where 2 walls meet.

Soffiting a sub won't gain any boost in output and you lose the ability to compensate for phase differences between sat's and sub by placement.

however, if your sub has a phase adjustment then I wouldn't hesitate to soffit them, I don't think it's neccesary though. It may however make the bass a little more defined as the sound waves will have a clearer path to your ears. A sub on the floor will radiate sound from the floor to your ears as well as bounce off the nearby walls and then to your ears. soffiting sould eliminate some of this.
