Thank you, now l understand.
Well, its really not a bassreflex box.
It's more like a copy of a Truels Gravesen design.
Google Gravesen and cyclop, and you understand.

I also have the original cyclop midrange box with the Seas 5" driver, but deside to leave it and maybe use it for tv-sound

^^ Ah, aperiodic. That makes more sense. Thanks, I was curious otherwise.

The GPA12's are good drivers but I'm not sure they'd be the best fit for an OB. I'd look at something more designed for the application as the GPA Q may be too low especially on a narrow baffle.

CD+horn top
1x GPA 414 mid
2x 15"beta SLOB bottom
Much more compact and similar if not better performance

Sell the remaining dozen GPAs and donate the $ to charity (or donate the GPAs to poor audiophiles). Happy holidays

I will keep my 1212" GPA's for bass duty. Very good sound from 30-200 hz.
Double GPA 12" for 200-1khz, black JMLC400 for the TAD2001 up to 9-10k and a T500 on top.
I think that's a good plan. And of course, a different color ;p

The Jantzen 8" and Eminence 15 beta can go up to the livingroom followed by a AMT l have in stock.
Family speakers

It works best to have a complete base colour already. The stone paint is basically just specks of materials. It cannot be relied on to supply coverage without really overdoing the texture. It works best, IMO, as an accent coat on an otherwise finished product.

As well, definitely do a test spray before going on a finished speaker, each can sprays a bit different and its easy to over do. It's almost best to imagine you are "throwing" the material onto the speaker, big sweeping movements with quick little bursts of the valve. Especially if you only want an accent.

After the stone paint I covered with a couple of coats of spray on polyurethane. This is important because the textured paint will collect dust and dirt easily and will not wipe clean otherwise.

Good advice. I found the black needs a pre-finish, but recently used the tan on some stands in bare pine and it was really nice on it's own. Also using Rustoleum bed liner on cabinets. Nice matte finish and light texture.

Great thread! I have a list of speakers I rotate through, but I am using these Holt Hill Audio Cionnsaile Monitors on matching stands at the moment. Connected to a restored Bogen DB230A integrated from 1959. Source is a Pioneer DPR-609 CD Recorder that I also use as a DAC, as well as a Bluesound Node. Turntable is usually a Revox B790, but I have it out of rotation right now to fix the dust cover.
