Hi Everyone, I am a newbie,

Converting my bomb shelter into a home recording studio room.

Soundproof alone is pretty good in this Bomb shelter but not for Acoustic treatment in the room. I read up Rockwool panel 8 to 12 inch thickness at 100kg/M3 is good for absorbing low frequencies and 45kg/M3 is good for high frequencies. Thus, should I DIY 2 types of panels, 45 and 100 or get acoustic foam for high frequencies but Rockwool for low frequencies? Room size 4m by 1.5m, Height 3.5m

Keyboard Amp is not so encourage for outdoor venues as some users claimed. What other types of speaker should I get one which serves outdoor and home use for Yamaha P-115 Keyboard while keeping the cost at SG$300 or less ? outdoor would cover room size of 25sqm of 9 rooms?

Love ya :-D

A question:

. . . What kind of recording do you want to do?

To record the P115, you should record straight from the "Line Out" jacks, without any loudspeaker. Add reverb with the P115 "effects", or with software. The room acoustics don't matter.

That's very strange. It's tall, long, and narrow -- like a book, on its edge. I would think about reducing low-frequency resonances relating to the 1.5 meter dimension. So, perhaps, heavy rockwool to cover much of the 4mx3.5m sidewalls.

For loudspeakers (if you don't want to use headphones for practice), "powered monitors" are the usual answer. JBL LSR305's are recommended by other people on this forum. There are lots of other choices:

. . . How much do you want to spend?

. . . How good should the sound be? How loud?

If you want to use the same speakers for PA use, I suggest PA speakers, not 'powered monitors'. The PA speakers have protection over their loudspeaker cones, and tougher cabinets. There is a recent thread about "What loudspeaker for jazz piano gigs?" -- you might read that.

Thanks so much Charles & Rille !

Really appreciate, I will get 5 to 6 panels made from 80 or 100kg/m3 rockwool smile
I am quite worried on the downside of using Rockwool material would be harmful to our lungs but gonna to believe what the supplier claimed thattheir material is not hazard to our health.

I would like invest on a PA, preferably above 200W.

Very elated to be engaging with all of you on this forum smile
