Hi, nice looking graph. The upper response, before it gets ragged, is one of the best i've seen

What driver is it ?

Xoc1 is right to ask about a HPF What type & f

yes i am using the linkwitz riley active 24 db crossover up to 110hz or the below two schematics .

>>>one is a schematics for subs only i found on the web
>>>the other is a 24db i designed using the linkwitz 24db calculatorhttp://sound.westhost.com/project09.htm#download_esp_lr Linkwitz-Riley Electronic Crossover to fit my needs to cut the frequencies below 35hz and above24khz so as to get maxx spl out of drivers.

I'm using the SW100 in my set.
Had a gig on Saturday night and used a TH115 and a TH118 together used Crown xti 2000's with both subs and the result was very nice you can really hear the 25Hx-40Hz increase with the TH118 low end punch was even more amazing in fact I played "Bust a Move" and I had to back off the volume the widows were seriously rattling so bad they would have cracked for sure.

The widows loose their husbands, then you try to rattle them to the point they crack .
