    First off, the smaller room is a fail. it does not meet the minimum volume requirements for a critical listening room. The larger, however, will do nicely with 2770 cubic feet. The modal spread is decent and if you can tweak the length slightly, you could meet The Bonello Distribution critera down to 20 Hz. As it is, you only have good modal dist down to the 40 Hz 1/3rd octave band...

    YOU can DIY your own treatment and you SHOULD treat five of the six room surfaces!

    The sweet spot won't be sweet without substantial treatment, well unless you want to wear your speakers like headphones. 😉 - I'm joking. 😛

    But seriously, you will need substantial trapping and reflection control - just for STARTERS! As you can afford it, build complete 'treatment walls'.

    Today more and more CDs (and subsequent hit records) are recorded in a home situation. The only problem that I have with the typical home studio is that it is usually NOT a studio, but a collection of studio equipment. In order for you to have a real studio, one that actually does the job of a studio, you must place your equipment in a room where it can function as designed. This means an acoustically treated and accurate critical listening room.

    Besides, a well-treated room is so much more fun!

    Take your time and get the trapping that you need installed. This can be as cheap as R-19 building fiberglass from Home Depot! As your skills building treatment improve, you can try your hand at some membrane types and diffusors. But please note that treatment placement is not arbitrary. It is important to know what you NEED here or there because Form Follows Function. 😉 - And certain devices don't function well in certain spaces. That said; you really cant' go wrong building broadband absorption. You really can not have too much trapping.

    Desk building: Be careful NOT to copy commercial desks! For example; small home studios should NEVER buy or build a look-alike Argossy or Sterling desk! These huge monsters are mainly used in Mastering rooms of very decent size. If they are too close to the main speakers, bad reflections/diffraction will result. - And never, ever, ever put your speakers on the desk or on the bridge of the console! (Sorry Warren) LOL!
