Rear Ported - Plug it?

[tmix]

I asked this question years ago (it seems) and got no definitive answers so I thought I'd ask again now that more peolple have proably tried this.
I have some or the original Alesis monitor ones (passive) that are rear ported. I would like to flush mount them if it would be benefitial in any way.
If I do flush mount them, should I plug the port or just let it fire into the triangular cavity they will be mounted in?


Thanks for your input!

Tom, I'm not sure on the Alesis rear ported monitors, but some of the Tannoy monitors actually shipped with plugs, to be used instead of the typical switches for half and quarter space, which kick in typically 3 and 6 dB shelving equalizers for low end.

I'm not nearly the speaker guru that Barefoot is, but personally I'd check with Alesis (or what's left of them) on this; my concern would be that different types of woofer would react differently to the change in air cushion stiffness caused by plugging ports. IOW, the Tannoys woofers may be better able to handle being effectively converted from bass reflex to acoustic suspension.

Personally, I'd leave the ports open and let them fire into the absorbent in the soffits - we've had members soffit mackies with their passive rear radiators and like the results.

All this is based only on "gut feel"; and Thomas has been so busy with his new speaker company for the last several months that I wouldn't hold your breath waiting for an answer from him - also, if you talk to Alesis you may get VERY negative comments about soffiting/flush mounting - some companies just don't get it, at least partially because they are more "resellers" than USERS. Don't let that stop you, you'll be amazed at the difference... Steve

Thanks for your time Steve.
I will consider going to Alesis for answers. I have a feeling I'll get a canned "cant do".

I may go ahead and prepare a flush mount shelf system in the walls. If it doesn't work well, I can always put a blank wall bezel up to cover the holes until I can save up for something that will work flush mounted.

I'd love to afford some of Barefoots stuff. I'm not sur he has anything in my price range. Once I get the building built, I'll have to see what my finances are. I probably couldn't spend more than 1500-2000 bucks though.

Thanks again for the answer, it agrees with what my gut says also.

Man, I thought I was a night-owl; it's even later where you're at! Are you up early, or stayin' up late? (Not that it's any of my biz, just realized it's time for quite a few people in your neck of the woods to be gettin' up - never mind...) Steve

It is my job that gets me up!

I go to work early so i have to get up around 3:30 am - 4:00.

I usually get to work aound 5:30 and jump on the internet and take care of "bidnez".

You know I really have to thank you guys for all the help I have gotten over the last couple of years, but particularly over the last few months.
I would have never taken the plunge to build my own studio if it were not for the info I have gleaned from this site.

I am basically just your average drummer -dude that absolutely loves recording and mixing. I have built homes with my Dad for 10+ years so I am not afraid to swing a hammer. But for the last 25 years had my main paying gig as a manufacturing planner for a small Aerospace company whilst playing and recording on weekends.

I am horrible on computers, which brings me to my next request .
I have searched for some answers to proper inside corner construction and have come up empty.

I understand your typical contruction tecniques for building wall corners (inside type).
Is there anything different that needs to be done for building corners where you are supporting the multiple leafs.
Under typical construction tecniques you would only have a small 1-1/2 " edge. After you put a couple of layers of rock on, it seems you would not have anything to nail to. Would'nt it be better to space a stud say.. 2-3 inches off each corner stud assy just to hang the multiple layers on and simply caulk the inside corners where they meet in the inside corner.

I have tried searching, and I can't see to come up with the proper search phrase. I have read through many of the stickies and still have not found the answers. If you would not mind , please point me to the proper posts.

Thanks again!

Tom, don't think there's ever been a "proper post" - so I drew this. Hope it helps... Steve

Steve,
Exactly what I needed!
I'm sure others can use it too!

Thanks again. I'll post other questions in the building forum.
