    Sorry to hear of the injury and glad you are ready to jump back in.

    Listening to lossless files from Mac Mini using Bit Perfect to deliver files to Schiit Modi DAC. Amp is an old Yamaha CR-2010.
    MIds are incredibly natural. integration of low/mid/high is seamless to my ears. Bass digs deep, release is quick and there is nice detail. Lots of the room and "air" up high. Soundstage is wide and there is some depth as well. Guessing this may get even better with more careful positioning. Most listening has been with acoustic music between 65 and 90 db (Jazz, Orchestral, Big Band, Opera) but am listening to SRV as I type this. That Strat is so glassy and smooth. These speakers should rock and slam as well. More on that later.

    I am going to give myself several days before I compare with other speakers here in the house. I have the ELAC B6.2, some small powered studio monitors (Adam A7) and a pair of JBL 4312B monitors.
    Thanks for the descriptions!

    Tough to imagine the sound without hearing them firsthand. I know I should just get back to building them and hear them first hand!!
    Looking forward to your comparisons.

    You inspired me to get back in the garage again though!!

    Can you give some more descriptive comments on the sound, and what type of music you like to listen to please?

    I like the idea of a color break along the longer seams. Thanks for that. Maybe a maple baffle and edge with black otherwise. Food for thought.

    Well, putting a fine paint finish on mdf takes a lot of work, seams can show through. A textured paint finish is easier. I have used stone texture paint frequently.

    Veneer with a painted baffle is an option. That speaker has a really big baffle, black might be overpowering.

    Duratex is a roll on coating originally for commercial PA cabs.

    Thank you! I have not yet decided. I imagine I will brush/roller a glue/water primer coat. Beyond that, who knows. Any ideas?

    Cabinet building is nearly completed. I arched the top of the front baffle with the router.

    The boards are 8.5" x 9.5" if that helps.

Basic cabinet plan is completed, Interior dimensions give me 42.9 liters. Crossover Speed Test Scrabble Word Finder Solitairelayout is done and I did a quick mock-up this afternoon. Seems like it is time to get the saw blade and router spinning. Here are a couple of quick pics. Please excuse the hand drawing - best I could do on the plane ride.
