Default 10" woofer choice

Hello, I'm looking for a bass speaker. (no subwoofer! )
fc should be around 300hz.
I'm looking for something with punch but clear, not imprecise.
My room is about 20m2 (feet?)
I'm hesitating between closed-box enclosure Seas l26rfx or bass reflex Monacor sph-275c.
Over it in mid bass there's a Davis 17klv6a
I can spend around 400$ for both speakers.

Don't know your budget but the Scan Speak Revelators seems like the most interesting woofers for low mid duty.

Obviously I can't read since you actually mentioned your budget in your first post!

With that budget you'd have to look for used Revelator drivers.

Ok thanks for your reply.
I wonder something:
Shouldn't it be better to choose a configuration with 2x8'' rather than 1x10"?
Maybe 2x peerless nomex?
The budget will be the same.

PS: I listen to many different styles of music, indeed I may have violin and techno in the same playlist

Hi,
I can't decide if you're looking for a bass speaker and don't want a sub woofer, or if you want a sub-bass speaker because you don't have one.

A sub-bass will require a different driver from a bass speaker driver.
If you want your sub to go more than quiet it needs volume displacement, i.e. Xmax times Sd should be large.
It also needs a fairly low Fs.
These two requirements usually rule out smaller drivers. You can get low Fs drivers that are small and by doubling them up get the very low bass oomph that a sub should provide. Multiple drivers usually cost more.

One thing is certain, sub performance = low efficiency, whether you go sealed or vented.

Have a look at the tapped horn thread and see if that could give your answer.

Ah, you don't really care about Fc then, you just want usable upper response for a 300Hz crossover.

Have you considered the Monacor SPH-275 you mentioned in a transmission line? If you can afford the extra space it should work well, I plan on doing this myself but haven't yet got the modelling software. I know it can be used up to and above 400hz so it fits that criteria, and the TL design should give strong bass to 30Hz or less.
