infinite baffle towards a back room ?

[Wolf11Man]

The Peerless FSL-1830R09-08 would be a nice fit for your door sub. It has a high excursion you usually do not find with drivers this size and price. Do not look at toutlehautparleur.com , it is ridiculous expensive there. Should be more like 150€.
What you also need is a small, bridgeable PA amp and a DSP to match it to your room (you find both at Thomann). Consider the Behringer DCX2496LE Ultradrive and a the t.amp E-800 as a combination. This pair is in the price range of a plate amp, but is higher sound quality, more reliable and much more powerfull. Last it has a very high price on the used market, if you want something new in the future.
A realistic budget for your sub will be 550-700 €.

PS the DSP will not only equalize your sub, but also match your main speakers to the room.

Thank you Wolf. I was thinking about buying the WIIM ULTRA with Fosi V3 Mono Amps

super, thanks a lot !

 

[DanielT]

thank you for the link and this is what matters, comment at the end of the link :

but other than that it sounded damn good

I think that this is way more important than all the measurments

Why not both? Measures well, sounds good and vice versa.

If you're interested, here's a thread that touches on that topic:

What role should listening play in speaker design

Note from staff: This thread has been split from another thread and best effort was made to preserve the flow. When we are talking whether a speaker has flat on axis response and well behaved off-axis, Andrew Jones (like other designers) leaves room for his own judgement over using...

yes Daniel, I wrote to quickly, of course, the measurements
are great as well and indeed a perfect way for us to communicate
since we cannot travel to each other houses. Thank you for the thread.
I will learn REW once I get my equipment installed.

IMO, it's already possible to study REW and the actual acoustics of your room. And simulate a subwoofer in the door (with greater benefit if the room is cuboidal).

I heard of someone here who was going to do a video tutorial on REW ?

 

[Flaesh]

@Keith_W signature contains a link to his book. I haven't read it and don't plan to, but I have reason to trust Keith. And I recommend this book. If you need any educational resources about REW. Especially meaning discussing your results and questions here on ASR.
What shape and size is your room? Including the placement of the speakers, the listening area, and that door leading into the front backroom.

 

[RaymondFromThePyrénéés]

Dear Flaesh.

Here is my choice of 2 rooms,
I am lucky to live with a women who tells me, whatever you like

I always thought that the bigger room number 2 was the best, room 2,
but perhaps not because the smaller room 1 has potentials :
I can if I want to, take away the wall of the back room,
or at least a large part of it,
and also,
I could take away the entire ceiling and increase headroom quite a bit,
I have not measured but at least 350-380sm (11.6-12.5 feet)
and also install 2 velux windows onto the roof to get some sun into this room facing west.

so finally the today smaller room 1 might be the best choice.

see my drawing below....

Here is the smaller room with the back room

Of course, I can take away the wardrobe and do whatever I want to this room.

and thank you so much for the information about the REW book for beginners.

For example

This doesn't require any special knowledge, and it's best to use it yourself.
For interpretation, it's best to compare the model with reality. A measurement microphone and some box with a speaker will be helpful.

ps: An unused fireplace can also be used. For more or less IB-ish sub

I always thought that the bigger room number 2 was the best,

Larger rooms tend to be better for bass because the Schroeder frequency (where room modes become problematic) is lower and less of the frequency range is affected (by room modes).

Plus, reverb sounds better in a large space. A lot of small-room reverb can sound pretty bad!

But I always say all rooms that fit into house are small compared to a concert hall or theater.

 

[RaymondFromThePyrénéés]

Thank you
I will star to look at REW, what about knocking down the ceiling for a much higher space under the roof, would that improve the sound ?

 

[RaymondFromThePyrénéés]

yes, but not all concert halls have great sound, to some exceptions known for their architectural achievements for concerts. I recall once listening to a pianist jazz player in a church, I quite in the middle of the concert, it was awful sounding.

If you can change a flat ceiling into an irregular one, that will help a lot. If you only make the room a larger cube, it will just change the frequency a little, but basicaly have the same problems.

 

[RaymondFromThePyrénéés]

in the smaller room, yes, if indeed I take away the ceiling,
the roof, once isolated, would indeed become irregular.
I can also take away the back room, or simply make
the door opening 4 times larger to get even more
irregularity either behind the speakers or behind
the listener. here is the attick, slanted roof and so on

 

[RaymondFromThePyrénéés]

If you only make the room a larger cube, it will just change the frequency a little, but basicaly have the same problems

that is interesting.... so then I should go with the smaller upper room and take off the ceiling. Another advantage is that the walls goes onto the exterior, no neigbours as opposed to the larger room with flat ceiling underneath.
