How can I improve this DIY kit

[JZatopa]

So I built a pair of parker audio 98's about 6 years ago. You can find the kit here

98 & 98 kit

I used a 2uf cap on the tweeter and the stock enclosure specs. Now I would like to improve the design. I have two ideas on how to improve the design but could use input.

My first idea is to improve the crossover. The only real improvement I can really see is to add a low pass to the woofers.

The second idea I have is to add a powered woofer to help fill in the low end. These speakers really don't have much bass and I don't think a different style of enclosure will really change this. I even thought about mounting these in a back loaded horn but unless someone else tells me different I think that a semi active design may be the way to go.

Aside from these change does anyone else have any ideas how I could really maximize the sound from these drivers?

Unless you can measure (or already know) the basic TS numbers for you drivers, a re-design is going to be pretty difficult.

No bass from 2 x 6.5" drivers in a 1.25 ft^3 box doesn't sound too promising.

Yikes!!......A system impedence of two Ohms? Ouch! For the 6.5"....
Looking at their site we have: Fs 60 Hz, Qts .26, Vas .78 Cubic foot, Four Ohm, 93 Db@1W1M. Not the best of specs...particularly the 60Hz Fs. That's a long way to reach down toward some deep Bass......& it won't get there.

Buy a much better/different kit? It's been 6 years after all!

I have considered a different kit but I figured that I should make the best of this one before I do that. The 2 ohms really isn't a problem with my amp and they can easily be wired in series to become 8 ohms if need be. The way I see this system, now that I have built it and learned quite a but, is trying to get bass from a midrange driver. The thing is that you can't get bass from a midrange driver. What do you guys think about adding a bass driver that is possibly powered? I would have the MTM played by my zen select and add a 12-15" woofer

 

[PeteMcK]

the first step is to measure the drivers...
with a low Qts, maybe reconfiguring them as a 2.5 way in an EBS alignment would work

I think you already answered your own question. Add a powered woofer.

I think you already answered your own question. Add a powered woofer.

What Cal said, but stereo and crossed a little higher than 80Hz

 

[JZatopa]

I am sure I can find the drivers but do you guys have any suggestion on an amp? If I go this way I think I may high pass the mtm at around 200-260 and have the powered part play from there down.

 

[Cal Weldon]

Might be best if you think in the 100-200 range. A lot of plate amps don't go up to 260. Check out Parts Express or Google "Plate amps for sale" Also best to buy an amp that has more power than you need an just go easy on the gain control.

My cheap and dirty solution was to buy a Behringer electronic XO and use an old stereo power amp I already owned, very cost effective way to do things
