Hey all,
Looking to build some bookshelf speakers for my computer for movies/music/games etc.
I looked at the Overnight sensations mtm and liked the look of them.
Then i remembered I have some nice parts left over from a car build and would like to use them.

If anyone can advise how to design and enclose & crossover to suit that would be great.
Being new i have no idea where to start. So go easy 😛
Thanks in advance!

Car speakers are 4 Ω ( subwoofers even 2 or 1 Ω )
Amplifiers distort double on 4 Ω loads so it's better to choose 8 Ω speakers

Hi,
Actually there are several different SB29 tweeters and SB17 midwoofers, please specify the exact driver models you have in order to avoid further confusions. Generally, SB drivers are of excellent quality and do promise a very good result. Only the crossover usually gets a little bit more complicated, that's the drawback. Are you speaking of an MTM design?

The speakers are:
SB Acoustics - SB29RDNC-C0004 Tweeters
SB Acoustics - SB17NRXC35-4 - 6.5" Mids
Im happy to go with recommendations in regards to MTM.
If it will be a much better speaker overall im happy to order a couple of extra mids to make it work.
Id just love to design a great set of speakers overall.

Yes, the woofer filter normally needs two series inductors (like in the EKA) and when the DC resistance of the two coils is taken into account then you need a volume of about 20 liters per driver for a vented design. The EKA only has 15 liters and is a little bit too small IMO.
So there are several options:
A vented MTM design in 40 liters with an impedance of 8 ohm. The speaker will go very loud and is suited for a living room. But it's too large for a bookshelf.
A vented MT design in 20 liters with an impedance of 4 ohm. A classic 2-way speaker.
A closed MT design in 6-12 liters, a small PC desktop speaker. 4 ohm as well and with limited low bass capabilities.
