Adding another 15 to my current box?

[orlando144 20]

Whats up SSA!

I have 2 Ascendant Audio Mayhem 15's running on a Soundstream dtr 1.3400 at .25 ohm

(3400 rms @ .5 2200 rms @ 1ohm)

I have the subs in around 6.2 cubic ft net and they get loud but im itching to get louder if i can...

I can get 3 American Bass HD 15's dual 1's and wire to .67 ohm... But can i just make another hole in my box? Thats the most airspace available.

Goals.. Hit 150 db (currently 149.1)

Should i keep the 2 15's or get 3 ?

If its a bad question/ idea input on that would be apreciated

Thanks

Your best bet is to design and build a new box for the two 15s.

[orlando144 20]

Also... Would it throw off any frequency response of the subs or enclosure?

Its tuned at 34 hz peaks at 49hz...

[S.DeYoung 968]

Yes and your port area is going to be inadequate. Adding any extra objects is going to throw off tuning.

I tried a box tuned higher but it dosnt sound apealing to me.

Any idea as to if a 6th order would get louder than a regular ported box?

[orlando144 20]

Seems reasonable about port area and tunning being thrown off

Ill try redisigning a box and see what results i get

Thanks for the help

I would stick with a regular ported box. Stick with the AAs, add more port area, and if possible add more power.

[orlando144 20]

Port length is what is bad about adding port area..

If the subs have more air space with the same power will it possibly get louder?

[orlando144 20]

I was looking at some DD 9515's locally but dont have the money

Keep the Mayhems or sell them and get the 95's ?

What don't you like about the Mayhems?

[orlando144 20]

What don't you like about the Mayhems?

I actually love the mayhems but i would like to get louder. Cosmetically they look bad but my friend said he would buy them

Seems kinda pointless ?

I think ill keep the mayhems and just work with enclosure designs

Higher tuning with a larger box volume will end up with an awesome low end output with good numbers.. Why does .9 dB matter when it's in audible to the ear?

When i metered 148.1 at 1 ohm and metered 149.1 same frequency... It sounded louder.. Noticably to where my ears started hurting/tickling

Where at 148.1 i had to lean towards the dash to get that feeling on the ears.

[S.DeYoung 968]

If you could tune a little higher it would help you. Would you be willing to go to 39-40hz? Try to get closer to your resonant frequency.

[orlando144 20]

Yeah i can do that

So tuning near resonant frequency gets louder? Ive had other boxes peak at 45hz..

[Ohjay 116]

An increase in enclosure volume and/or power should get you to 150 and allow you to retain the lower tuning you desire.

I would get with one of the box designers/builders here on SSA and see what they have for a recommendation.

would help as well!

I wanna try learning from designs myself and building myself

More experience is always good ?

Right you are, Ken.

But don't get discouraged when the first attemp fails. Hands on learning is the best way to learn and succeed. SPL #'s take testing and building to reach your goals.

[bhsdriller 24]

Mayhems are very nice subs...I would get the DD's over them
