Want to build (2) 8" small subs.

Hi all, haven't been here in a while. Was helped by many members to build my (4) dual 15" Dayton subs for my theater. I could use your help again.


I have a small 11'x11' art room and I would like to build 2 small subs. I am looking for good SPLs and accuracy. I want 2 subs to achieve good room response. Want to keep under 2cuft for each sub but not a cube. I rather tall skinnier shape because I have very little floor space. I might even mount these to the wall where the ceiling meets in the center of both sides of the room.


I love my Dayton subs in my theater so I was initially looking at their 8" HO and HF models. Also looking at the Tang Band W8740-p but I don't like that it uses foam. I worry about it deteriorating after 10 years or so.


I am willing to listen to any options.


My art room setup.
Denon DVD-910 CD player
Onkyo TX-8050 stereo receiver
Schiit Uber Bifrost D/A converter
Emotiva EPA-2 Gen 2 Amp
DefTech Studio Monitors SM-65s Speakers


Thanks in advance,
WMD

God loves me, but everyone else thinks I'm an a$$hole.
My small dedicated theater.

What is the max size of the cabinets you are willing to accept?

What amp will you be using to power these?

Are you going to apply any eq to them?

Will these be for music only? In that case you don't have to chase 20 hz output.

I thought about it but it is a tad too big. Also, with it being a horn, I don't have any flexibility on the shape of the box like I do with sealed or ported.

Trying to keep under 2cuft. The amp will depend on the driver and design.

I would like great output down to 30hz and usable 25hz signal.

If you need small speakers, have you considered an isobaric design subwoofer? You would have to buy twice as many drivers but you would cut the box volume roughly in half. You might even get by with smaller drivers than 8". I was working on a sub wit two 6.5" drivers when somebody made me an offer for the drivers that I could not refuse.

10" and 12" drivers should be possible for sealed subs in that volume. I wouldn't limit yourself to looking only at 8" drivers.

True but it is not necessary for dual 10s or 12s in such a small room.

Also, i forgot to mention that my budget is $500 max for everything.

Okay, but for example, a 860w, 1060w, and 1260w are basically all the same price.

There is an 8" design (called "The Digger") on the Parts Express Tech Talk forum that gets rave reviews. The designer is a buddy of mine, and a very nice guy.

It might be worth a look.

My money would be on a pair of tens in small sealed boxes(less than 1 cubic foot).
Add eq as needed.
The PE drivers you mentioned above would be good choices.
If you end up going this route be sure to buy more watts than you think you need.
Good bass needs watts lots of them.

Yeah, I've got a Digger 8 hidden in my kitchen. Tall and skinny, can probably build a pair for the $500 budget.

Thanks for all the great relies. I ended up ordering parts to start dual Digger 8s. When all is siad and done, I'll have spent just under $700 on these.

I went with:
(2) Infinity Ref 860w 8" subs
(2) Bash 300s 300w amps
(2) Creative Sound Solutions APR12s 12" passive radiators

I wish someone would have done some measurements of this sub because I feel like I'm taking a chance on this. Anyway, I will be doing some measurements when mine are built.

Go over to Parts Express Tech Talk and PM JSR.

He may have taken measurements.

He is a very nice and talented guy.

I run two of these (soon to be four) in my small room HT/music setup. They rock. Original design is ported, but I wound up running them sealed (better integration with mains/room, 17Hz flat in room response):

DOH just saw you already started in on a design. Have fun!
