I built my first speaker
I've been lurking around for awhile and have made some posts about what I was doing. Well I actually built my new center channel. It's a small 2-way vertical configuration (13 1/2 x 7 x 9 external) with a Hiquphon OW 1 tweeter and a Scanspeak 5" revelator woofer - the low Qts model.
I said I built it, in actuality Lou Coraggio determined the volume, 8.5l, and the port size. I built the box,took it to Lou's house today and we mounted the elements, he measured them, computed the crossover, then built it!
I must say I witnessed two different examples of black magic- the measurements and the crossover design. I intend to learn how to do this, but it's a daunting prospect.
We listened to it for a while and Lou got up and added 1/2 ohm to the L-pad, even I heard the difference. Well we probably listened to his evaluation tunes for another half hour or so and neither of us wanted to change anything else - it sounded gorgeous!
I took it home, with the makeshift external xover, to audition with my sources, equipment and room. I tried it as a center channel and was quite pleased but I wanted to listen to some music. So I listened to a Norah Jones CD (in mono) while watching my Celtics almost blow a 24 pt lead
I was totally enthralled (you can't believe the bass that comes out of that little woofer) and I would be very happy with a pair of them for my mains but that's another project. Next up is a subwoofer.
I'll post some pictures as soon as I 'finish' it. Right now it's just bare BB and MDF. For the sides, I resawed some African mahogany veneer, 1/16" thick, which I'm going to dye a 'very' red mahogany. The baffle, top and back will be gloss back, I haven't figured out if I'm going to make a grill or not. I also need to make some kind of base.
Well, if you couldn't tell, I'm tickled pink and feel so incrediably lucky that I was able to meet and work with Lou,

Congrats, those seem like they are great but....
I'm just that guy. www.sru.edu
"It has been remarked that if one selects his own components, builds his own enclosure, and is convinced he has made a wise choice of design, then his own loudspeaker sounds better to him than does anyone else's loudspeaker. In this case, the frequency response of the loudspeaker seems to play only a minor part in forming a person's opinion."
L.L. Beranek, Acoustics (McGraw-Hill, New York, 1954), p.208.
I can vouch for the 5.5" Rev also...
I have mine in 18 ltrs vented to 30Hz, and I just absolutely love their sound. My favorite project as yet.
I gotta admit...
top end drivers, a bit of good luck, and a dose of experience add up. When John gets done with critical listening, and damping the cabinet, I'll post the design. It's a lot easier with high end components.
Many thanks to Dave Ellis for the "test mules". The Hiquiphon is an exceptional tweeter. The SS 15W/8530K woofer does put out an extraordinary amount of CLEAN bass in a small box.
Re: I built my first speaker
My suggestion is build a total of three of them. your front right and left and your center.. then build two subs from scanspeak 23 w drivers. then build another pair of the 2 ways. talk about a hi-end ht! we won't mention the cost will we.LOL! In a way I am jealous I started with low priced cone drivers etc. I have worked my way up the ladder.
