The music really is fantastic. The nominal impedance is noted as 8 ohms and the measured DCR is about 6 ohms. The AlphaA voice coil diameter is 38 mm 1. The pair of Eminence AlphaA woofers measured very close to one another. This is particularly effective when the HF source is directional, as widebanders are.

The Eminence AlphaA woofer driver comes neatly packaged in a split moulded styrofoam shell and snuggly inside a sturdy cardboard box. Guy 13 Logged aquapiranha Jr.
Logged matevana Full Member Posts: Eminencw was wondering what type of material you made your baffle out of? The overall build quality of the AlphaA woofer drivers appears to be very good.
I apologize my late reply, I missing it for some reason, I ashamed for it, sorry. An Eminence AlphaA sticker covers the small rear motor structure of the woofer which features a vented pole piece. Rudolf Full Member Posts: Dont know quite where to go next, but do have four extra Bs on hand. From the datasheet the Eminence AlphaA woofer drivers have a noted usable frequency range of 46 Hz to 3. Considering their size and the size of my apartment — the OBs don’t feel large or overbearing.
The Eminence AlphaA woofer has a small motor and a high Q ts which makes the driver well suited for use with open baffle speaker systems. Thanks Glen for your nice detailed reply.
Hello Glen, Beautiful images, a great OB, must made wonderful music surely. The nominal impedance is noted as 8 ohms and the measured DCR is about 6 ohms.
May I also know what crossover you are using? Anyway, I’m a newbie at any type of speaker building and am also interested in building a H frame sub using 15 inch driver s. Cookies help us provide you a better browsing experience.

Since you’re talking about modifying, then with the round frames of all drivers in yours, rminence you considered flush mounting them? Cool setup you have there. King has done some excellent work with the AlphaA see links at bottom of page and found it to be a well performing open baffle woofer that can produce excellent bass output down to about 40 Hz.
Because of the good OB performance and low cost for the AlphaA woofer, this is one of the more popular woofers for open baffle speaker configurations.
The relative 2-dimentionalness of them keeps them ‘small’ in the room. I absoutely love the way your setup looks! Mono records sound alpha-15q and wide when the baffles are square to the room.

Logged JohnR Facilitator Posts: Ekinence official Eminence AlphaA datasheet is in the links below. I’ve been running this set-up for a while now and have really been loving it — just thought I’d share some pictures.
It depends on the crossover frequency between the two drivers. I just caught this and wanted to compliment you on your speakers.
